Our Dollis Hill gas safe registered engineers can carry out repairs and fittings of complete central heating systems and associated gas/water appliances. We can service and repair all types of boiler systems and replace old central heating units. With local Dollis Hill heating engineers, who cover gas heating and electric heating, we are only 30/90 minutes away when you need our assistance.
Whatever the job entails, large or small, we have the experience and professional attitude to carry out any heating services. On top of this our local Dollis Hill engineers can undertake landlord inspections and prepare buyers' reports.
Mid-position Valves
This is a valve used to direct hot water to certain parts of the heating system. Depending on the current sent the motor, this can be in one of three positions: De-Energised which is hot water only (to supply to taps), Fully Energised is central heating only (to only supply water to the radiators), and Mid-Position, where hot water is supplied simultaneously to the hot water taps, and the radiators. Because of how these valves work (the motors stall intentionally to remain in one position), they can burn out frequently. They can be replaced fairly easily, but we will need to check part availability with our suppliers after an initial assessment visit.
