Solar Hot Water Repair Service in Canberra

How to fix broken solar Hot water systems

There are many reasons why a Solar hot water system will fail to provide hot water.

The most common reasons are..

The electric or gas booster has been turned off. To fix this you can check your switches, fuses and valves. You can also check your owner's manual for relighting instructions. If your booster does not work after this you will need a Solar hot water repair service.

The solar collectors are in too much shade or they are dirty. To fix this you can chop back any overhanging branches and clean your collectors with soapy water. You should also check that your collectors are facing towards north at a pitch of 45-55 degrees.

The glycol or heat transfer fluid has leaked away ( roof mounted tanks and a small number of split systems). To fix this you will need a solar hot water repair service.

The solar circulating pump is not working. To fix this you should check all 3 pin plug connectors and check sensors are fit well into the sensor ports. Test power supply with a low wattage lamp. If there is power at the pump supply replace the pump. If there is no power at the pump supply and the sensors are secure in their ports you will need a Solar hot water repair service.

Either the sensor wire in the tank or in the collectors is faulty. To fix this check both sensors are secure in their ports. Check that the wires between the sensor and the solar controller are not broken. If the sensors are secure in their ports and they are not broken you will need a solar hot water repair service.

The hot water tempering valve is faulty. To test the tempering valve check the temperature of the water coming out of the storage tank. This can be done by holding a thermometer under the outlet of the relief valve while pulling the lever on the valve to release water slowly. If the temperature of the water coming out of the relief valve is significantly hotter than the water coming out of the hot taps you will need a solar hot water repair service.

The pressure and temperature relief valve is constantly running. This is normal during sunlight hours and during boosting. If this occurs in other times you will need the assistance of a solar hot water repair service
