Solar water heaters are an important component in a house. They provide a constant supply of hot water for domestic or commercial use efficiently and cost-effectively, using free solar energy. Having basic knowledge about solar water heater repair is necessary if your water heater breaks down and you want to keep the expenses low. Like other solar-powered devices, solar water heaters can develop issues as time passes and elements start to deteriorate.

Seek expert advice from Sharpe Services when your need to repair or replace your existing Solar Hot Water System. Solar-powered heaters are durable and reliable. However, that doesn’t mean that they do not experience problems from time to time.

Solar Hot Water

COMMON PROBLEMS

As with any other devices, solar water heaters are also prone to problems, element failures that cannot be avoided, and situations that would lead to costly repairs.

The most common issues with solar water heaters are sediment build-up, corrosion of the metal parts, deterioration (ageing, wear and tear) of the non-metallic, freezing (in cold climates), fluid leakage, and insufficient hot water supply or no hot water at all.

Water not being hot enough

One of the issues with Solar Hot Water systems is that they are more susceptible to changes in the weather than gas or electric heaters. This is because cloudy conditions mean that the panels on the roof will not convert as much energy as on days where there is a clear sky and the sun is beating down on the roof of the house.

One possible cause of the water not being hot enough could be that the panels are positioned incorrectly on the roof. A professional will be able to work out whether the panels need to be moved and placed on a different part of the roof.

Panels not working at full capacity

Panels need to be working at maximum capacity in order for water to be heated at maximum temperature. The panels should be working at no less than 80% capacity after 25 years. Panels which are older than that may experience problems with their efficiency. Repairs or replacements will need to happen if the capacity of the panels seems to be dropping below that threshold.

Panels coming loose from the roof

If solar installation is not done properly, there is a danger that they could come loose. Solar panels should be regularly checked to make sure that they are still firmly in place. The panels can be refitted if they are found to be loose. Have the panels inspected frequently to ensure that there is no damage.

Novices should never attempt to remove these panels by themselves because there is a possibility that the panels could be damaged beyond repair.

Conductor Rod not working properly

Certain types of solar heaters use a conductor rod in order to heat the water effectively. Sediment in the tank or corrosion on the conductor rod could cause it to malfunction.

Sudden changes in the water temperature

Sudden changes in water temperature can be incredibly inconvenient if people are trying to wash their clothes successfully. A change in water temperature can be dangerous for anyone who is taking a shower because they could suffer serious burns.

Fluid Leakage

Fluid leakage is one of the major problems that your solar water heater can develop. In fact, it is one of the leading issues commonly associated with solar-powered water heaters. This problem is usually caused when a collector glazing or pipe is broken, or when the pressure relief valve in the solar panels is damaged and open.

Another possible cause of water leakage in a solar-powered water heater can occur due to lose pipe fittings and thermal expansion.

Unusual Noise in the pump

When you turn ON a solar-powered water heater, and hear an unusual noise coming from the pump, the chances are that there is a sediment build-up on the pump’s impeller, obstructing the impeller from rotating. Another possible cause of unusual noise in the pump is due to bearing failure. Also, make sure air is not trapped inside the system.
