- Although most water heaters last 10–15 years, it’s best to start shopping now for a new one if yours is more than 7 years old. Doing some research before your heater fails will enable you to select one that most appropriately meets your needs.
Long-Term Savings Tips:
- Buy a new energy-efficient water heater. While it may cost more initially than a standard water heater, the energy savings will continue during the lifetime of the appliance.
- Look for efficient water heaters in the following categories: high efficiency gas non-condensing, gas condensing, electric heat pump, gas tankless, and solar.
- Consider installing a drain water waste heat recovery system. A recent DOE study showed energy savings of 25% to about 30% for water heating using such a system.
- Heat pump water heaters can be very cost-effective in some areas.
- Install a temperature controlled hot water recirculation valve, which provides instant hot water (so water is not wasted down the drain waiting for water to run hot at your faucet or shower). The Hot Water Lobster Instant Hot Water Valve is a simple eco-friendly DIY installation (no water pump required) and can save an average household up to 17,000 gallons per year. It also saves energy costs and can prevent pipe freezing.
Prevent Your Pipes From Freezing:
The best solution to preventing your pipes from freezing is to simply install innovative and patented technology known as a “temperature controlled hot water recirculating valve” (is a breeze-no pipe cutting, soldering or electrical connections). It uses your existing water pipes and the thermal convection generated by your water heater to circulate the water back to your water heater for reheating (not requiring a pump or any electricity). These systems are temperature-controlled and are easily adjustable to meet your particular temperature needs. There is no water waste and it also reduces the energy required to heat your water while it provides instant hot water to your faucets and showers. A trickle of water circulating in your pipes will keep your pipes from freezing in most circumstances.
