We got new furnace installed for heating in Fall of 2009. Everything is fine except we do not get that much hot water in upstairs bathroom. The furnace is in the basement. The kitchen faucet on the first floor gets really nice hot water but not the bathroom on the second floor.

It takes almost 5 mins. to get the hot water in the bathroom and after that it keeps getting hot to cold, back and forth. We live in New England so Winters are very cold. It takes a lot of courage to get in the shower!

We did not have this problem with the old furnace. I know there is dial on the furnace to make the water hot/cold. We tried that but that did not help much. Actually, that made kitchen water very hot. All of us take shower at different times so this is not the case of hot water used up by the first person who took shower.

I really need some help. Any suggestions will be greatly appreciated.

Thanks in advance.
