Troubleshooting the thermostat on your water heater might look difficult. But with this guide, you can handle this task without contacting a professional. 1.Head to the circuit breaker and turn off the power to the thermostat. This step is vital because it protects you from electrical shocks. If you are working with a two-pole breaker, both breakers will go off at the same time. 2.Pull out the two...

Replacing a Water Heater Thermostat in 8 Steps Remember, this is for electric water heaters: 1.Safety first, cut the power off at the breaker. 2.Remove the access panel(s) and insulation so you can access the thermostat(s). You may have one or two access panels. Most water heaters have two elements/thermostats. 3.Use the voltage meter to make sure the power is completely off. 4.Take a picture of t...

For homes without ducts, air-source heat pumps are also available in a ductless version called a mini-split heat pump. In addition, a special type of air-source heat pump called a "reverse cycle chiller" generates hot and cold water rather than air, allowing it to be used with radiant floor heating systems in heating mode.

Geothermal (ground-source or water-source) heat pumps achieve higher efficiencies by transferring heat between your house and the ground or a nearby water source. Although they cost more to install, geothermal heat pumps have low operating costs because they take advantage of relatively constant ground or water temperatures. Geothermal (or ground source) heat pumps have some major advantages. They...

A relatively new type of heat pump for residential systems is the absorption heat pump (AHP), also called a gas-fired heat pump. Absorption heat pumps use heat or thermal energy as their energy source, and can be driven with a wide variety of heat sources such as combustion of natural gas, steam solar-heated water, air or geothermal-heated water, and therefore are different from compression heat p...

A number of innovations are improving the performance of heat pumps. Unlike standard compressors that can only operate at full capacity, two-speed compressors allow heat pumps to operate close to the heating or cooling capacity needed at any particular outdoor temperature, saving energy by reducing on/off operation and compressor wear. Two-speed heat pumps also work well with zone control systems....
