There are two styles of central heating pump: One is a fix headed and the other is a variable headed. The first pump will run at a single rate of speed, which forces the hot water around the system at a constant rate. The speed of variable pumps is variable. When fitting a variable headed pump the installer such as Eastcote Plumbers can balance the radiators, then adjust the speed achieved by the to find an optimum temperature for every room. If you can’t increase a room’s temperature by opening the radiator’s valve, then adjust the speed of the pump. But before adjusting the system pump, you really must make sure that all your radiators are showing the same drop in temperature. In order to confirm this, you can buy thermometers that will clip onto the radiator and indicate the temp. Connect one of these thermometers to the feed pipe just below the radiator valve and the other one to the return pipe, also below its valve.The difference between the temperatures registered by the thermometers should be about 11°C (20°F). If it’s not, close the lockshield valve slightly to increase the difference in temperature or open the valve to reduce it. Having balanced all the radiators, you can now adjust the pump’s speed slowly and in small turns until the temperature of the radiators is what you want. You may need a specialized tool which will depend on the pump you have fitted. Switch off the pump before making each adjustment. Any doubts don’t hesitate to contact a professional service.
