Selecting Vaillant
Selecting a model of boiler requires consideration of the type and condition of home you are heatings. Age of your home is important, system setup, number of radiators, insulation grading, dwelling type, if your home is an apartment what floor you are on is important. Storage radiators verses radiators with convector fins also matter. Furthermore if you have a system fault you will need to troubleshoot, fault find and almost always replace parts.
Typical problems
Vaillant Combi Boilers have common problems like most other boiler types. The EcoTEC Plus sometimes have an issue with the pressure build-up at the pump. Typically you will recieve a F.75 fault letting you know that the system did not reach the required pressure rise at the pump, resulting in your boiler not firing up. Other problems include combustion seals leaking, heat exchanger blockages, hose failures, leaking diverter valves and faulty pressure sensors. Almost all boilers will get trapped air or low water pressure within the circuit (system). This common issue that can be overcome by bleeding the air from the radiator. Furthermore additional water can be put back into the system via the mains valve. However ensure that the operating pressure is not exceeded.
Warning!!! Please remember it is a criminal offence to work on a gas appliance if you are not qualified to do so. If you have an issue please call a boiler specialist who has the proper qualifications and experience and is GAS safe registered.
