Do I need a motorised water valve in a system with gravity fed hot water and pumped central heating ?
Although a DCD Controller may be installed without a control valve for hot water, this is in fact an essential later enhancement if maximum benefits are to be obtained, and should be introduced at the first opportunity. A hot water control valve will enable the boiler to be run at its maximum, when it will operate most efficiently and heat your home and hot water in the shortest time. The temperature of your water at the taps can then be programmed to whatever you choose for different times of day. The DCD Installation Instructions describe how you connect valves in a system with pumped central heating and gravity fed hot water. One valve is needed in the water circuit with a gravity hot water system for temperature control, but one may also be put in the heating circuit to stop creep’ in the summer months. It is in fact vary rare for a valve in the heating circuit to be needed.
