I really like the idea of hot water, I like the simple setup, However and I know it goes away from this thread but, is it a)cost effective, and b)worth all the hassle?
Cost of gas, short ammount of time it's frosty, I think I'll stay with the cold until I can justify the spend.
Just out of interest, how do you get over the seventeen minute cut off thing? that would drive me wild on big jobs.
