Tankless On-demand Water Heaters

All solar hot water and solar heat systems require a backup for days when sufficient solar energy is not available. One of the most cost effective solutions is an on-demand tankless hot water heater. Most homes in the US have a large water tank that is heated all day, despite the fact most hot water is consumed within a few short timeframes.

An on-demand unit can instantaneously provide hot water to your entire house right as you need it, without the cost of continuously heating a large storage tank of hot water. They have thermal efficiency ratings as high as 92%, and with no pilot light you save an additional 48 gallons of fuel per year. When you turn on the hot water faucet the flow triggers the burner, which rapidly heats the water as it passes. When the flow stops, the burner turns off. With a tankless on-demand water heater there are no worries about running out of hot water because there is no tank to become empty.

All on-demand systems we sell are solar compatible and can handle the incoming warm water provided by your solar system or cold tap water.

Tankless water heaters are small and self contained. Normally they will be installed in the same area your existing tank is located. The units we normally sell are designed to provide hot water for all existing needs throughout your home.

There are also mini units, commonly referred to as “point of use” heaters. They are designed to provide hot water to 1-2 faucets, such as just one bathroom. These would not normally be used as part of a solar backup system.

Compared to an electric water heater, on-demand will save 25% (avg use of 40 gallons per day). Replacing your current water heater with an on-demand unit today will save you money immediately as well as become your first step towards installing a solar system.
