Welcome to our forum.
OK, i got 70 degrees from the tap. So that means only +30 rather than +50 and put the heating time down to 10 hours
Except for well water, I thought 50* sounded a little chilly for piped in water.
Are you saying that the water comes out of your faucet at 50? I would think it would be a little higher than that. What part of the country are you in, Alaska?---that was just a guess on my part. I'd never bothered to measure it. Hopefully warmer here in Pennsylvania. Think i'll check that out tonight.
