Reliance Tankless Water Heaters at HPM Building Supply

NEW! Tankless Water Heaters by Reliance

Reduce Your Energy Cost

Heating flowing water through a spiral coil is not a recent invention. The concept dates back to the early 1900’s. Back then designs required owners to light the burner for each use. Since the advent of electronics, the process has been automated to make for a very energy efficient way of providing homes or businesses with precise, abundant and cheap hot water.

Unlike traditional tank-type heaters that heat water and store it for future use, tankless units heat water nearly instantaneously as it is needed. In that way you’re only paying to heat water that you actually need.

And because tankless heaters don’t have to store heated water, they are much smaller. This creates two advantages: space savings and even more energy efficiency. Since they’re the size of a carry-on bag can be mounted high on the wall, you can put them just about anywhere inside the home or outside,–even inside a cabinet. So you don’t waste valuable floor space.

Secondly, because they’re small you can locate them closer to where you use the most hot water. This decreases the amount of water that gets heated but sits unused in your pipes on the way to the kitchen or bathroom.

How much will you save? Industry experts say tankless-types are over 30% more efficient than tank systems, and save homeowners between 30 and 50% off their energy bill.

We recently began selling Reliance® tankless heaters, all propane-powered:

We also offer a PVC venting system for use with the 320 LIH (shown above). This concentric PVC vent allows combustion air to be brought in from the outside and exhaust gasses to be discharged to the outside through only one opening in the exterior wall. And as it is PVC, it is much more affordable than stainless steel venting required for other non-condensing units.

All models are ENERGY STAR® qualified and come with a 12-year limited warranty on the heat exchanger plus 5-years on parts.

Of course tankless systems satisfy code requirements for use in place of solar hot water systems (which are also available from HPM). Come into your local HPM Building Supply to check out our display, or visit the Reliance website.

    Water heaters have successfully used the heat pump technology for more than three decades. This is a field proven technology and they have combined it with their innovative tank design to develop an integrated heat pump water heater, which is considered as second to none in the market.
