With any unit that you own it helps to understand the best way to repair any problems that it has. The most common model that people will use is the Worcester gas boiler. This will provide hot water and heating directly from the unit rather than taking it from a separate cylinder.

You must first check to see if the problem is in the thermostat. Turn the boiler off and allow the pump to continue running. When the boiler is cooled off, move the thermostat control lever. If there is no clicking sounds than you need to call a technician to fix it. This means the thermostat is too low.

Is there enough water in the system? You need to shut the boiler down and look inside of the feed and expansion tank. If it is empty this could be a problem with the valve. The simple fix might be too loosen it up or it might be frozen.

Every few months you should place a descaling solution into the unit. If you wait too long you will hear banging inside of the pipes. This is caused by a build up of limescale and could damage parts of it. Shut the boiler off and place the solution in the unit. Make sure to flush the system when it is done.
