Even brand-new A-rated (condensing) boilers waste water, gas and money; independent tests show that your boiler wastes the first ten litres of water when you turn on the hot tap. CombiSave is an award-winning British innovation that can help you reduce the amount of water and gas used in the initial heating process, saving you water, gas and of course money whilst also helping the environment.
CombiSave reduces the amount of water needed by the boiler in the heating process, saving an amazing 55,000* litres of water per year. (*Figures based on independent tests by EA Technologies.)
How It Works
CombiSave is a thermostatically controlled valve made from de-zincification resistant brass. By controlling the flow of water during the initial firing process, the CombiSave accelerates the heating of water and reduces the amount of fuel needed in the process. The CombiSave can even be fitted to older models, so it’s a great way of making your home more energy efficient without buying a brand new combi-boiler.
When the hot tap is turned on, the CombiSave reduces the flow of water until it has reached a set temperature. At this point, the valve opens fully and allows the hot water to flow throughout the system. The CombiSave will save an average of 8 litres of water every time the tap is turned on from cold.
CombiSave is factory set to open at 45 degrees centigrade. Installers are able to raise or lower this setting by +/- 5 degrees centigrade as required.
