One of the most popular types of central heating system is the vented or pumped system which comes with an expansion tank and a feed. The task of the tank is to provide the radiator with heat and provide hot water to your house. The tank also makes space for any kind of water expansion that might be a result of the heating process. The tank needs to be placed in an elevated position, preferably the loft. It will heat the house effectively and also supply hot water.
There is also the sealed central heating system, which is essentially a packaged unit with all the needed safety devices and controls. The water, in this system, is supplied from the main water supply directly.
