This page is all about hot water, how it gets hot, the different methods to heat it and the different fuels that can be used to heat it. There will be suggestions on how you can reduce the amount of wasted money and fuel used to keep water hot when you are not using it. According to the U.S. Department of Energy, water heating accounts for 20% or more of an average household's annual energy expenditures. The yearly operating costs for conventional gas or electric storage tank water heaters average $200 or $450, respectively. Storage tank-type water heaters raise and maintain the water temperature to the temperature setting on the tank (usually between 120°-140°F or 49°-60°C). Even if no hot water is drawn from the tank , the heater will operate periodically to maintain the water temperature. This is due to "standby losses": the heat conducted and radiated from the walls of the tankand in gas-fired water heatersthrough the flue pipe. These standby losses represent 10% to 20% of a household's annual water heating costs. One way to reduce this expenditure is to use a demand (also called "tankless" or "instantaneous") water heater.

Laing AutoCirc
Stop wasting water by running it down the drain while you wait for it to get hot. The AutoCirc pump is installed under the sink or faucet farthest from the water heater -- where hot water usually takes the longest amount of time to arrive. A built-in temperature sensor automatically turns the pump on when the water temperature in the hot water supply line cools down to 85º F. This cool water in the hot water supply line is then pumped into the cold water line and back into the water heater. This means the coldest temperature at the time of turning on the hot tap will be 85 degrees.
