How effective is the GasSaver and SuperFlow in the summer period?

With no central heating operation, there is obviously less wasted energy to recover, however tests have shown that the GasSaver can still recover enough energy to supply around 15% of the hot water demand. Of course, there is less demand for hot water in the summer, so the GasSaver's key effectiveness is in winter - when you need it most. The SuperFlow system can be controlled by a twin channel time clock, allowing operation of the thermal store in summer without activating the main heating circuit.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
