Boiler hot water heater not working.

The most obvious reason an electric heater doesn t work is that it s not receiving any power. One sign of this is if you need to turn the central heating to maximum in order to get any hot water. Reset the tripped circuit breaker or replace a blown fuse. If you have eliminated any other causes listed above and you still have heating but no hot water or your boiler heating is not working but the water is then it is likely that you have a problem with the diverter valve.

If you have no hot water there are several possible reasons and you need to work through each of them methodically to eliminate each one and this will also depend on whether you have an electric or gas powered heater. If the diverter valve is not working properly it could be stuck in the central heating position or may have developed a fault. An absence of hot water generally occurs as a result of all the hot water in the tank being used up for example by running both the washing machine and dishwasher at the same time. Maintain the water level in the boiler at half full the boiler s automatic filling system controlled by the pressure reducing valve should maintain the proper water level at 12 to 15 psi of pressure.

All repairs and handywork should be conducted by a qualified gas safe registered engineer. Over time water contaminants can build up and harden in the bottom of your water heater reducing its ability to produce ample hot water. The circuit breaker or fuse controlling the furnace may have tripped or blown. This is is a valve that opens and closes to provide heat to the radiators or to heat your water.

They also allow the homeowner to use renewable fuels and some companies are even offering mixes of heating oil and biodiesel which produces less pollution than heating oil alone.

Oil fueled boilers and heating systems are popular in areas where there isn t ready access to natural gas.

A water heater that produces no hot water may not be getting power or it may have a tripped limit switch or one or more failed heating elements. First check the water heater s circuit breaker in the service panel to make sure it hasn t tripped. In the case of not enough hot water or hot water that is not hot enough it may be that you need to replace the heating element on your water heater.
