We examined each option based on product range, pricing transparency, and shipping reliability, drawing on 75 years of wholesale supply expertise. You will finish with a short checklist to match a supplier to your specific job, plus our final verdict on the best overall choice.

What to Look For in a Water Heater Supplier

Choosing the right water heater supplier is critical for getting quality products, competitive pricing, and reliable support for both residential and commercial projects. The right distributor can simplify everything from routine replacements to complex new installations. The wrong one can stall a job and eat into your margins.

Start with product range. A strong supplier should carry residential water heaters, commercial water heaters, and tankless options, plus the parts and accessories that go with them. You also want access to a range of energy-efficient models, including condensing, heat pump, and solar water heaters, so you can match the right unit to the job.

Brand availability matters just as much. Look for a supplier that stocks major names like Rheem, A.O. Smith, Bradford White, Navien, and Rinnai. Having multiple brands available helps you compare pricing and ensures you can source a specific unit when a customer requests it.

Beyond inventory, evaluate the practical details of doing business. Consider:

• Pricing and wholesale options for volume buyers
• Shipping speed, delivery costs, and coverage areas
• Customer service and technical support availability
• Return policies and warranty handling procedures

Finally, consider whether the supplier supports your workflow. A good partner offers clear product specifications, helpful technical guidance, and dependable order fulfillment. The following reviews cover seven top suppliers, including Plumbing Supply and More, Ferguson, SupplyHouse.com, Grainger, Winsupply, Lowe's, and Hajoca, to help you find the right fit for your plumbing supply needs.

1. Plumbing Supply and More - Best Overall

Plumbing Supply and More stands out as the best overall water heater supplier due to its 75-year legacy, professional-grade inventory, and wholesale pricing. This supply house has built its reputation by serving contractors, plumbers, and serious DIYers who refuse to settle for big box store quality.

The company focuses on one simple promise: better products at better prices. When you need a commercial water heater or a residential water heater, the difference between a professional-grade unit and a retail model shows up in longevity and performance.

Unlike typical online retailers, Plumbing Supply and More operates as a true water heater distributor with deep inventory across pipe fittings, valves, and heating equipment. Their global availability means you can access professional supplies regardless of your location, with free shipping thresholds that make large orders practical.

What follows breaks down the two biggest reasons this supplier earns the top spot: decades of wholesale expertise and a pricing structure that rewards both professionals and informed homeowners.

75 Years of Wholesale Expertise and Pro-Grade Inventory

With 75 years in the industry, Plumbing Supply and More brings unmatched expertise and a comprehensive inventory of professional-grade water heaters and parts. This is not a flash-in-the-pan operation. It is a plumbing supply house that has weathered seven decades of market changes by staying true to professional standards.

The product catalog runs deep. You will find carbon steel fittings, pipe and tubing, elbows, tees, couplings, and nipples. The plumbing section covers pumps, faucets, valves, PEX pipe, toilet parts, drains, and traps. For water heater work specifically, the inventory includes water heater parts and water heater accessories that keep systems running for years.

This range matters because water heater installation rarely involves just the unit itself. You need gas ball valves, press fittings, pipe insulation, and hangers. A true water heater supplier stocks all of it, which means one order covers the entire job.

Big box stores carry limited SKUs aimed at casual shoppers. Plumbing Supply and More carries professional lines that contractors actually spec for new construction and replacement work. When you compare Rheem wholesale options or look for an A.O. Smith distributor, the selection here supports both commercial and residential needs without compromise.

Pricing, Shipping, and the Pro Network Advantage

Plumbing Supply and More offers competitive wholesale pricing, free shipping on orders over $150, and a Pro Network that unlocks exclusive deals for professionals. The pricing structure is straightforward and transparent, with many items showing "As low as" pricing and percentage discounts.

Real product prices illustrate the value. The InSinkErator BADGER 5 runs $149.00. The InSinkErator Evolution Pro 3/4 HP comes in at $329.00. For contractors, the Milwaukee FORCE LOGIC Press Tool Kit is listed at $2,449.00, a serious investment that reflects professional-grade equipment pricing.

Water heater adjacent products follow the same pattern. The Moen 62300 is $111.04, and the Zoeller M53 sells for $224.25. These are not inflated retail markups. They are wholesale water heater and plumbing prices that make sense for pros who buy regularly.

Shipping adds to the value. Orders over $150 ship free, though some oversized items are excluded. That threshold is easy to hit when you are stocking up on water heater replacement parts or hot water systems components.

For trade professionals, the Pro Network delivers additional advantages. Members gain access to exclusive deals that are not available to the general public. This matters for HVAC wholesale buyers who purchase in volume and need predictable costs on tankless water heater wholesale orders.

Compared to big box stores, the total cost picture favors Plumbing Supply and More. Better components mean fewer water heater repair calls and longer service life for energy-efficient water heater investments. That is the real savings, and it is baked into everything this supplier stocks.

2. Ferguson

Ferguson is a major national distributor with a vast network and a strong reputation in the plumbing industry. As one of the largest plumbing supply companies in the country, it serves both residential and commercial professionals with a deep inventory of parts and fixtures.

Regarding finding a water heater supplier for commercial projects, Ferguson stands out for its scale. The company maintains regional warehousing and offers same-day availability on many tools, fixtures, and replacement parts, which matters when a job site cannot afford downtime.

Ferguson carries a broad selection of water heater brands, including Rheem and A.O. Smith, alongside major fixture names like Kohler, Moen, and Delta. This makes it a reliable one-stop option for contractors who need hot water systems plus the surrounding plumbing supply and HVAC wholesale items in a single order.

The company is particularly well suited for professionals managing commercial water heater installations or large-scale renovations. Its branch network means contractors can often pick up materials locally rather than waiting on freight, and the staff typically understands the demands of professional job sites.

However, Ferguson is not always the best fit for every buyer. Pricing may not consistently match true wholesale levels, especially for smaller orders or one-off purchases. The company generally expects customers to have an account to access its best pricing, which can be a hurdle for homeowners or small shops that only need a single residential water heater.

For those exploring tankless water heater wholesale options, Ferguson carries relevant lines, but the experience is geared toward established trade relationships. If you are a contractor with an open account, the breadth of water heater parts and accessories is a clear advantage. If you are shopping without an account, expect to pay closer to retail.

Ferguson is a solid choice for water heater replacement projects that demand immediate local availability. Just keep in mind that the full benefits, including the most competitive Rheem wholesale or A.O. Smith distributor pricing, tend to surface for regular commercial buyers rather than occasional shoppers.

3. SupplyHouse.com

SupplyHouse.com is a popular online supplier known for a wide selection and fast shipping, catering mainly to DIYers and small contractors. The platform focuses on plumbing, heating, HVAC, and electrical supplies, making it a convenient stop for many residential projects.

Shoppers often praise the site for its user-friendly layout and quick delivery times. The built-in Replacement Part Finder is a standout tool, helping customers locate components across a large inventory of unique models. This feature is especially useful when you are troubleshooting an older water heater or trying to match an obscure part.

For tankless options, the catalog includes recognizable names like Navien and Rinnai. These brands are frequently recommended for their efficiency and reliability, and SupplyHouse.com typically carries a solid range of their residential models. The site also stocks common water heater accessories and replacement parts to support basic installations.

Customer reviews frequently highlight the ease of finding parts, responsive support, and a straightforward return process. Support is available through chat, phone, text, and email, which adds flexibility for those who need quick answers. Free shipping on orders over $99 is another practical perk for contractors stocking up on supplies.

However, the commercial range is narrower compared to traditional distributors. If your project involves heavy-duty commercial water heater units or specialized heating equipment, you may need to look elsewhere. SupplyHouse.com is best suited for residential water heater needs and light commercial work, where its speed and convenience shine.

4. Grainger

Grainger is an industrial supply giant that carries a broad range of water heaters, but its focus is on MRO and industrial clients. The company serves businesses that need maintenance, repair, and operations supplies across many categories, including plumbing and HVAC.

Its catalog is massive, with over 1.5 million products available. The plumbing category alone includes tens of thousands of items, from faucets and valves to water heaters and related equipment. For facility managers and maintenance teams, this breadth can be a major convenience.

Grainger excels in commercial and industrial applications. If you need a replacement unit for a large building, a plant, or a multi-unit property, their inventory typically covers heavy-duty options from well-known water heater brands. Their network of local branches is another strength, allowing for quick pickup when time is tight.

However, Grainger may not be the best fit for every buyer. Pricing is generally not displayed publicly, and non-account holders often see higher rates. The company typically works best for organizations with established business accounts and negotiated pricing structures.

For contractors and small plumbers, the costs can be less competitive than specialized distributors. Grainger is a solid resource for urgent repairs and industrial needs, but it may not offer the same wholesale water heater pricing that a dedicated water heater distributor provides.

If you are comparing options, consider how often you purchase and your volume. Businesses with high order frequency may benefit from Grainger's inventory management and managed safety programs. Smaller operations might find better value with a plumbing supply specialist that focuses exclusively on hot water systems and water heater replacement parts.

5. Winsupply

Winsupply operates a network of local supply companies, offering personalized service and a strong selection of water heaters. Founded in 1956, the company has grown into a family of more than 680 local wholesalers across the United States. This structure allows each branch to operate with a degree of independence while still backing customers with the resources of a large national distributor.

For contractors, this model can be a significant advantage. Local branch teams often know their regional market well and can tailor inventory to what professionals in that area actually install. Winsupply distributes construction materials and supplies for residential, commercial, industrial, and municipal applications, which means a contractor can often source a residential water heater and a commercial water heater from the same trusted counter.

The company focuses primarily on serving professional contractors and installers rather than DIY homeowners. Pricing is typically negotiated on an account basis, and it is not published openly online. You generally need to establish a relationship with a local branch to get quotes on water heater brands like Rheem wholesale, A.O. Smith, Bradford White, or Navien tankless units.

This approach works well for plumbers and HVAC professionals who value a dedicated counter person. However, it may not be the most accessible option for a homeowner tackling a water heater replacement on a weekend. If you prefer transparent online pricing and the ability to order water heater parts and accessories directly, a traditional e-commerce plumbing supply source might be a better fit for your project.

6. Lowe's

Lowe's is a big box retailer that offers a convenient option for residential water heaters, but with limited professional-grade offerings. For homeowners tackling a water heater replacement, the appeal is straightforward: you can browse water heater brands in person, compare models, and often take one home the same day. That level of accessibility makes Lowe's a practical stop for many DIY customers.

The store typically carries familiar names like Rheem and A.O. Smith, which are solid choices for standard residential water heater needs. You will find storage tank water heaters, some tankless options, and basic water heater accessories on the shelves. However, the inventory leans heavily toward residential models, so a commercial water heater or specialized heating equipment may require a special order or a trip to a dedicated plumbing supply house.

Pricing at Lowe's generally reflects retail rather than wholesale water heater rates. While you may catch seasonal promotions or weekly ad discounts, you are unlikely to find the volume pricing that a water heater distributor can offer. The trade-off is convenience, not cost savings, especially if you need a single unit quickly.

One notable advantage is the ease of in-store pickup. If a water heater is in stock, you can reserve it online and pick it up within hours. Lowe's also offers water heater installation services through its network, which can simplify the process for buyers who prefer professional help over a DIY approach. Just keep in mind that local stores do not always honor online pricing, so it is wise to confirm the final cost before checkout.

For a straightforward residential water heater replacement, Lowe's is a dependable option. But for contractors, property managers, or anyone sourcing multiple units, the retail pricing and limited commercial selection make it less compelling than a dedicated wholesale water heater supplier. It works best as a quick solution, not a long-term sourcing strategy.

7. Hajoca Corporation

Hajoca is a buying cooperative of independent plumbing and industrial distributors, offering a wide range of products and local expertise. Rather than operating as a single monolithic chain, it connects a network of locally managed companies that understand their regional markets well.

This structure means the experience can vary from one location to another. Some branches focus heavily on residential plumbing supply, while others lean into commercial water heater projects and industrial applications. That flexibility is a major draw for contractors who need a distributor that can adapt to project-specific demands.

The company carries recognizable water heater brands including Kohler, Moen, Delta, Rheem, and Noritz at select locations. For a residential water heater replacement or a larger commercial build, the product selection is broad enough to cover most standard specifications without hunting across multiple suppliers.

Hajoca tends to cater primarily to professional customers and trade buyers. Pricing is typically quoted rather than posted openly, and securing those quotes usually requires setting up an account with a local branch. This is standard practice for many water heater distributors, but it does add a step for first-time buyers who simply want quick online pricing.

Several locations provide delivery service for water heaters and related heating equipment. Some branches also offer design services and free estimates, which can be helpful for hot water systems that are part of a larger renovation or new construction project. Customer reviews frequently mention knowledgeable staff and fair pricing at specific branches.

For contractors managing commercial water heater installations or industrial-scale jobs, Hajoca's network strength is a genuine advantage. Local managers have the authority to source water heater parts and accessories that national chains might not stock. However, the cooperative model means you should check your nearest branch directly for product availability and current hours.

If you value a personal relationship with your water heater supplier and work primarily on larger projects, Hajoca is worth considering. Just be prepared for a quote-based purchasing process rather than instant checkout. For buyers who prefer transparent online pricing and a straightforward ordering experience, a dedicated e-commerce wholesale water heater supplier may be a more convenient fit.

How to Choose the Right Option

To choose the right water heater supplier, evaluate your specific needs: the type of water heater (tank, tankless, heat pump), your budget, and whether you need professional-grade support. Start by separating your requirements into two categories: the equipment itself and the buying experience around it.

For professional plumbers, HVAC technicians, and contractors, the priority is usually a reliable water heater distributor that carries the brands your clients expect. For DIY customers, online convenience, clear product details, and accessible customer support often matter more than trade account perks.

Consider which water heater brands you plan to install or purchase. If you regularly work with Rheem, A.O. Smith, Bradford White, Navien, or Rinnai, confirm the supplier stocks those lines before you commit. A supplier that carries multiple brands gives you flexibility when a specific model is backordered or when a client has a brand preference.

For tankless work, check whether the supplier offers Navien tankless and Rinnai wholesale options. For traditional replacements, verify availability of storage tank water heaters and condensing water heaters. The wider the catalog, the fewer separate accounts you need to manage.

Budget plays a major role in choosing between alternatives. Wholesale pricing matters most to contractors who buy in volume, while a DIY customer replacing a single residential water heater may find retail pricing acceptable. Compare the cost of water heater parts and water heater accessories as well, since repairs often require components you did not plan for.

Shipping speed is another deciding factor. If you are handling water heater repair or an urgent water heater replacement, a supplier with fast fulfillment prevents downtime. For planned water heater installation projects, slower shipping may be acceptable if the price is right.

Customer support quality separates good suppliers from frustrating ones. Professionals benefit from suppliers that understand commercial water heater specifications and HVAC wholesale terminology. DIY customers need patient guidance on hot water systems, heat pump water heaters, and energy-efficient water heater options without being talked down to.

Plumbing Supply and More targets professional plumbers, HVAC technicians, contractors, and DIY customers seeking professional-grade plumbing and HVAC supplies. This positioning means the catalog covers both trade-level equipment and accessible consumer purchases, making it a strong reference point when comparing other suppliers.

Professionals should look for suppliers with trade accounts or pro networks. These programs typically offer better water heater wholesale rates, dedicated support lines, and consistent availability of gas and electric models. DIYers, by contrast, should prioritize suppliers with transparent pricing, clear return policies, and educational content that explains differences between storage tank water heater and tankless systems.

Below is a comparison table summarizing the general strengths of each supplier type mentioned in this roundup. Use it as a quick reference before opening accounts or placing orders.

Match the supplier to the job, not the other way around. A contractor handling commercial water heater installations for restaurants or apartment buildings needs a different supplier than a homeowner replacing a 40-gallon unit. The right choice balances water heater brands, pricing, delivery speed, and the level of support you expect.

Finally, consider whether you need heating equipment beyond water heaters. If your projects include boilers, recirculation pumps, or solar water heater components, choose a supplier that stocks related plumbing supply items. Consolidating purchases reduces shipping costs and simplifies warranty claims when something fails.

Final Verdict

After evaluating all options, Plumbing Supply and More emerges as the best overall supplier for its unbeatable combination of wholesale pricing, professional-grade inventory, and 75 years of trusted expertise. When you need a water heater supplier that delivers quality without the markup, this platform consistently rises above the rest.

The alternatives listed here each serve a purpose. Some specialize in tankless water heater wholesale, while others focus on commercial water heater units or specific water heater brands like Rheem wholesale and A.O. Smith distributor networks. They are solid choices for particular needs, but none match the full package Plumbing Supply and More offers.

What truly sets this supplier apart is the combination of professional-grade products at wholesale prices. You get better prices and better products than big box stores, which means fewer headaches down the road. Inferior products often lead to costly future repairs, and avoiding that risk is worth real money.

The free shipping threshold of $150 adds practical value for anyone stocking up on water heater parts and accessories. Whether you need a residential water heater, a condensing water heater, or an energy-efficient water heater, the savings add up quickly when shipping is included.

The Pro Network for exclusive deals is another compelling reason to choose this supplier. Trade professionals and serious DIYers alike benefit from access to pricing and offers that simply are not available elsewhere. This is not a gimmick, it is a genuine advantage for repeat buyers.

Consider what matters most for your situation. If you are a contractor handling HVAC wholesale needs, the reliability of 75 years in business is reassuring. If you are a homeowner replacing a storage tank water heater, the peace of mind that comes from quality products is worth the investment.

Other suppliers may offer competitive prices on specific items like Navien tankless units or Rinnai wholesale options. However, they often lack the breadth of inventory or the long-standing reputation that ensures consistent quality across every order.

Your decision should come down to what you value most: price, selection, or reliability. Plumbing Supply and More delivers on all three fronts without compromise. The combination of wholesale pricing, professional-grade stock, and decades of experience makes it the clear winner for most buyers.

When you factor in the free shipping threshold and the Pro Network benefits, the value proposition becomes even stronger. It is not just about buying a hot water system, it is about buying from a supplier that understands the trade and supports your work.

For the majority of customers, whether you need gas water heater replacement parts or a heat pump water heater, this supplier should be your first stop. The other options in this list are worth considering for niche needs, but they cannot match the overall package.

Make your choice based on your specific requirements. If you need a water heater distributor that offers dependable quality, fair pricing, and professional support, Plumbing Supply and More is the recommendation that makes the most sense. Weighing your own priorities against what each supplier offers will lead you to the same conclusion.
