Heat Pumps basically are a refrigeration circuit that is configured to be more efficient at producing heat than cooling. Heat pumps are used to heat swimming pools, provide hot water for commercial or domestic use and as central heating boilers. Heat pumps extract heat from the air in the case of air to air or air to water systems, while geothermal heat pumps extract heat from the ground.The repair and maintain heat pumps helps if you are a handyman with a range of skills.
Heat Pump Repair Stages
Before attempting any repair of a heat pump or any other electrical appliance disconnect it totally from the mains supply failure to do so can result in injury and even death. The repair of a heat pump can be broken down into two areas the first being the electrical system the second being the refrigeration system. One of the most important things to check on a monthly basis is that the evaporator and condenser heat exchangers are clean. If filters are fitted to the heat pump clean them once a month. A common electrical failure found on all types of heat pumps is the control thermostat. This thermostat usually senses the hot water circuit. To check if it is working turn the thermostat to maximum with the heat pump not running the heat pump should start. If it does not it is worth replacing the unit with a new one.
Condenser Fan Motor Tips
Another common fault is the condenser fan. The fan is a permanent split capacitor start and the capacitors sometimes fail. To repair this fault remove the capacitor from the fan and buy and exact replacement. Basically good maintenance consists of checking and cleaning all filters both water and air, and on the refrigeration circuit checking the tightness of the refrigeration gas pipe connections. Always be careful to use the correct size spanners on the pipe joints as they are easily rounded off. Heat pumps given regular maintenance will give years of trouble free operation.
