CombiSave Energy Saving Valve for Combination Boilers
WRAS APPROVED ~ WATERWISE RECOMMENDED - UK ENERGY INNOVATION WINNER

CombiSave is a thermostatically operated valve that can be fitted to the majority of new and existing wall hung combi-boilers. By controlling the flow of water during the initial firing process, CombiSave accelerates the heating of water and reduces the amount of fuel required.

BENEFITS

Save Water - CombiSave reduces the amount of water needed by the boiler in the heating process, saving an amazing 28,000 litres of water  (four person household).*

Save Gas - CombiSave helps make combi-boilers more energy efficient. As the time taken to heat up your water is reduced, you will use much less gas. And with a CombiSave fitted, you can turn ‘Pre-Heat’ off and save even more on your Gas bill, sometimes up to £75.00 per year!*

Save Money - Reductions in use of water and gas can save you hundreds of pounds, and as CombiSave is a ‘fit and forget’ device, you won’t have to worry about lots of expensive repair bills.

Save Time - The CombiSave will provide your hot water much quicker than the boiler, thus saving you precious time every day – and how can we put a price on that?

Save CO2 - Reducing the amount of resources your home uses makes it more efficient and helps reduce your carbon footprint. Making small changes can make a big difference to the planet.


THE FACTS

Independent tests show that as soon as you switch on your boiler, the first ten litres used in the process of heating water are wasted. As such, more gas than is needed is burnt, excess carbon is produced and time is wasted.
 
Why waste fuel, money and time waiting for your hot water?

THE SAVINGS

Over the year, a two person household could save:

  • Around 28,000 litres of water
  • 611 kwh of gas per year
  • Around £250 off your water and gas bills and carbon savings of upto 130kg
  • Up to 21 hours over the course of the year saved by not waiting for hot water
  • Around 260kg–500kg of Carbon dioxide per year, helping the environment

TECHNICAL DATA

The CombiSave is a thermostatically controlled valve made from de-zincification resistant brass. It is fitted with two rotatable elbows, which allows ease of fitting to a range of 15mm pipe configurations. All nuts and olives required for fitting are supplied along with a fitting guide and instructions.

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.

FREQUENTLY ASKED QUESTIONS

Can I install CombiSave in low water pressure areas?
Daily water demand can fluctuate causing variable water pressures at peak periods, particularly in flats and in built up areas. A simple way of simulating low water pressure is to flush the toilet and whilst the CombiSave is cold, turn on a hot tap and ensure the boiler ignites. Refer to installation instructions for minimum pressure requirements and setup procedure.
 
Are there any Combination boilers where CombiSave is not currently recommended for use?
Yes. Boilers that already incorporate a water saving device such as Potterton Puma, combination boilers with built in storage e.g. Glow-Worm extra max, and boilers with inbuilt thermal store e.g. Worcester Highflow.
 
Can we install CombiSave on boilers with a pre-heat function?
Although CombiSave is compatible and works well with pre-heat systems, to maximise savings it is recommend that where possible, the pre-heat function is turned off.However, there are boilers like the Ideal ISAR where this is not possible and therefore a CombiSave would not be suitable. When a Combination boiler is used with the pre-heat function turned on, it is not as energy efficient.
 
Why can’t you just turn down the hot water tap?
It is widely acknowledged that Water Utilities have tried to influence the behaviours of customers to reduce unnecessary water use. Even the most regimented and disciplined household will probably not achieve the savings that CombiSave can bring.CombiSave has been developed so that the end user does not have to change their behaviour to allow significant household savings.
