In-Store Exclusive

This one's worth the trip to the store.

Brands like Weber, Milwaukee, Yeti, and DeWalt restrict where their products can be sold online — and for good reason. In-store buyers get authentic products, full manufacturer warranty, and access to pricing that simply isn't allowed to be advertised on the web.

  • Authorized dealer network · Full manufacturer warranty & support
  • Guaranteed authentic · No counterfeits, no gray-market resellers
  • The brands set these standards · Be wary of sellers who don't follow them

About Product Overview

This Reliance 40-gallon propane water heater is built for homes running on LP gas where a dependable hot water supply matters day to day. The 36,000 BTU burner is rated Low NOx, which keeps emissions down while still delivering solid recovery for a household-sized 40-gallon tank. It's made in the USA and CSA listed, with a temperature and pressure relief valve built in for safety and a 6-year warranty backing the tank.

Top water connections and a 1/2-inch gas connection make it a straightforward swap for standard residential installs, and the 3-or-4-inch vent diameter gives some flexibility depending on your existing venting setup. It's rated to operate up to 10,100 feet in elevation, so it holds up in mountain communities as well as at sea level. This is a residential unit, sized and built for typical household hot water demand, not commercial-duty use.

Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

Ask our counter. Or theirs.

Most hardware stores can do more than you think. If we can't help you, the folks down the street probably can — just ask at the counter.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a familiar banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
