One of the most frustrating things in any house or office is waiting for the hot water to get to the faucet or shower. It can seem like an eternity and is also one of the biggest wastes of water.
The following article based on NAHB Research shows a solution to this problem. However, read the part bout how the solution can, if you aren’t careful, waste energy.
Innovative and temperature controlled hot water recirculation valves use thermal convection to circulate the hot water to your faucets and showers and do not require a pump.
A recirculation system provides a means to get hot water from a water heater to your faucet or shower, while simultaneously sending cooled water (from the hot water lines) back to the water heater to be reheated. In addition to having the convenience of instant hot water at your faucets, these systems conserve water and often save energy and can save the average household 17,000 gallons of fresh water a year and get faster hot water.
Hot water recirculation systems are commercially available nationwide through the manufacturer, distributor, plumbing wholesale supply warehouse or at selected retail home stores. No special approval or requirements are needed to install this system into your home or office. Some jurisdictions are offering a rebate on the purchase and installation of hot water recirculation systems. Warranties range from 1 to 10 years depending on manufacturer and model.
