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.

About Product Overview

This Reliance tankless water heater skips the tank altogether, heating water on demand with a 199,000 BTU burner that can run on natural gas or propane. Because there's no storage tank to keep hot around the clock, it only fires up when you need hot water, which is the main draw for anyone tired of a big tank taking up closet or utility space - or paying to keep 40+ gallons hot when nobody's home.

The Low NOx burner and Energy Star certification point to efficient, cleaner combustion, and CSA listing confirms it's been tested to recognized safety standards. A temperature pressure relief valve is built in, and the unit handles elevations up to 10,100 feet, so it works for installations well above sea level. Bottom water connections and a 3/4-inch water connection size, along with a 1/2-inch gas connection, keep installation straightforward for a qualified plumber. Backed by a 15-year warranty, this is built for residential use where steady hot water matters.

  • 199,000 BTU output, natural gas or propane
  • Tankless design - no standby tank capacity
  • Low NOx burner, Energy Star certified
  • CSA listed for residential use
  • Handles elevations up to 10,100 ft
  • 15-year warranty

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.
