CombiSave Is...
...a thermostatically operated valve set to become an essential add-on for new and existing “in-situ” combination (”combi”) boilers.
Tests show that a combi-boiler can waste the first 10 litres of water between the time the hot tap is turned on and the water running hot. Meanwhile, excess gas is burnt, carbon produced and the consumer waits!
A CombiSave valve is suitable for retro-fitting to any make of wall hung combi-boiler in less than 30 minutes and will not affect boiler warranty. The device is small and 'fit and forget', needing no power supply or maintenance.
Through thermostatic flow control during the initial fireing and heating process CombiSave accelerates the heating of the hot water and reduces the fuel needed.
Add in the reduction in carbon footprint and it's a win-win-win situation: a CombiSave fitted in 50,000 homes could save a whole reservoir of water in a year, together with associated treatment costs, as well as 12,500 tonnes of CO2 per year.
| Application | Operation |
|---|---|
| The CombiSave is designed to fit on the domestic hot water outlet of a combination boiler to reduce the amount of water wasted while waiting for the boiler to heat the water. It will also greatly reduce the time to heat the water thus saving on gas as well. | The CombiSave is installed on the domestic hot water outlet of the combination boiler. When the hot tap is turned on the CombiSave will reduce the flow of water until it has reached the set temperature. At which point, the valve will open fully and allow the hot water to flow freely to the tap. Saving an average of up to 8 litres, each time the tap is turned on from cold. |
| Physical Description | The Bucket Test |
| The CombiSave is a thermostatically controlled valve made from de-zincification resistant brass. It is fitted with two rotatable elbows which allows for easy fitting to a range of 15mm pipe configurations. All nuts and olives required for fitting are supplied along with a fitting guide and instructions. | The water savings can be shown by carrying out a very simple test (The Bucket Test) before and after fitting the CombiSave. When the hot water system is cold place a bucket under the hot water tap. Turn on the tap collecting the water in the bucket. When the water starts to run hot turn off the tap. Make a note of the amount of wasted water you have collected in the bucket. Repeat this test after fitting the CombiSave and compare the level of water collected compared to the previous test and you will see the saving. |
