The savings are only a half to a third less in the summer as the incoming mains water is some 10-15 degrees celcius warmer than in January. (so you could double your savings roughly)

Independent tests by consultants EA Technology have shown that CombiSave can save a two-person household an average of 27,756 litres of water and a little over 600 kWh of gas a year – as well as reducing CO 2 emissions by 130kg. No, there is no evidence of this. The components of CombiSave have been carefully chosen to be suitable for all areas. As my boiler's up in the loft the preheat function runs quite often because it's cooler and in winter before I fitted the timer it would preheat a couple of times every hour wasting gas and electric. Cabinet Secretary for Environment and Rural Affairs, Lesley Griffiths, said: “This is great news. People are continuing to benefit from the Nest scheme which helps make their homes warmer and more fuel efficient.”

The Nest scheme is part of the Welsh Government’s work to reduce the number of people who are struggling to keep their homes warm and cope with high utility bills. Heating and plumbing specialists Parr and Evans, which has more than 25 years of experience of providing heating systems to people in the Bristol area, now advise most customers – where appropriate – to fit a CombiSave. CombiSave is a valve which help you reduce the amount of water and gas used in the initial heating process, saving you time and money, and helping the environment. CombiSave can be fitted to most combination boilers and is an effective way to improve overall efficiency – reducing the amount of water that is wasted every time a hot tap is turned on and helping to reduce household bills because the time it takes to heat the water is so much less.” As soon as the hot tap is turned on, CombiSave reduces the water flow until the set temperature is achieved. From there, the valve opens fully and allows hot water to flow throughout the system. CombiSave can help you save as much as 8 litres of water each time the tap is turned on from cold.

Kenny Maxwell added: “It’s a win-win for both the consumer and the installer. On the one hand, householders save money on their utility bills, while plumbers and heating technicians can demonstrate to their customers how they can help save them money whilst gaining a new income stream.” It means that even more households can now take advantage of the savings that CombiSave can generate.” On average, it will take around 30 seconds for hot water to get to your taps.
