Heating water accounts for up to 30 percent of the average home’s energy budget. Some manufacturers of tankless water heaters claim their tanks can cut your energy costs by as much as 50% over regular heaters.
Savings & Efficiency: Tankless water heaters are an affordable option for energy savings. A tanked water heater constantly uses energy to heat and reheat water. Standby heat loss creates waste. And, since going green is very important, a tankless heater is a fantastic investment. Tankless units allow you to easily reduce waste and reach economic efficiency.
Heat as much water as you need without paying to keep it stored. With a tankless model you benefit from a constant supply. Simply turn on the hot water faucet.
How it works: A propane tankless water heater uses a flame so hot you don’t need to keep water sitting in a storage tank, eating up energy dollars while it waits to be used. You simply turn on a hot-water faucet. A flow sensor will activate a propane gas burner to heat the water. The heating will continue until you turn off the faucet, at which point the gas burner shuts off.
