what you have to remember is when us cold water users clean in this weather , by the time the water gets to the window our water is all ready warm

this is because the sun heats it up
1 the hose on the ground water come out is already warm
2 the window it self is all ready hot and the water get warm them as well
and I have not told you the best bit .... we have stated that your hot system is better in summer then in winter which kind of defeats the object and we have warm water thanks to the sun and we are not paying a penny for it
