Tankless Water Heaters
Hot water on-demand with 10-20% water heating savings
Throw away your water heater tank and shave ten to twenty percent off your water heating bill. Tankless water heaters have an electric, gas, or propane heating device that is activated by the flow of water. Once activated, the heater provides a constant supply of hot water. Large units intended for whole house water heating are located centrally in the house while, in point-of-use applications, the water heater usually sits in a closet or under a sink. Residential gas models are available that can heat more than five gallons per minute by 60°F, generally more than enough for two showers to be run simultaneously. Whole house electric units typically have a capacity closer to three gallons per minute.
