Hi, I’m from Mole Group, I saw on here people talking about CombiSave. It’s great that our product has got people talking! I just wanted to answer a few of the questions raised...
1. Does it really save £150 per year on gas bills?
Yes, you really can save that much! Check out our fact sheet on
www.combisave.com to see how these figures were calculated.
2. Whats the difference between CombiSave and the Potty Puma?
The Potty Puma method works differently from a CombiSave in that the Potterton Puma valve did not save water.
3. Will it greatly reduce my water consumption?
The average savings are 6 litres each time the hot tap is run from cold (average taken from 100 fittings).
4. Does it significantly reduce the waiting time at the tap for the hot water to arrive?
CombiSave can be retrofitted to most types and ages of combi boiler. Those that are fitted with an eco-button/pre-heat function are using gas while these are activated. The pre heat on boilers do not always keep it up to temperature as they heat the water up and let it cool down a bit and then boost it back up again. When the tap is turned on the boiler still takes a little time to fire up so most times the water will run warm, then you will feel the water get cooler and start to slowly warm up again. So the CombiSave will still assist by helping the boiler warm the water quicker. But if you turn the pre heat off you will save more money as it is not continually heating the water all the time
5. You can achieve the same thing by running hot taps slowly until they warm up?
Yes, it does work on the same principle as turning the hot tap slightly until the water is hot. But as stated, it would be unlikely that everyone in the house and their guests could be trained to do this each time accurately. Also you can’t regulate the flow on some appliances such as washing machines and showers. Just as we buy remotes for TVs but we could do that manually too!
6. What about potential damage to the boiler?
CombiSave imitates an “intelligent tap” so does not affect boiler mechanisms. The lifespan of a CombiSave is 10-20 years and the oldest one fitted to the rudimentary design has been in place problem-free for five years.
7. What effect will killing the flow until the water heats up have on the boiler?
The initial flow will not be “a trickle”, but is approx a third normal flow, so enough to rinse off something before full flow of hot comes through.
8. Won't it increase limescale formation within the boiler in hard water areas?
No, there is no evidence of this. The components of CombiSave have been carefully chosen to be suitable for all areas.
