Regarding the furnace, I have just purchased the house (move in on 4/24) and
yes this has always happened.

Since my last message. I have taken another look and found a plastic dial
with numbers on it and on the cast iron part of the valve(?) is embossed
hot\cold. I assume that this is a mixing valve and have tried to adjust the
valve all the way in one direction and then all the way in the other,
letting the shower run for a 5-10 minutes each time. Both ways I
experienced the same results... cold shower.

I also noticed that the valve is tied into the system with three threaded
fittings and looks VERY replaceable. I'm sure Home Depot would have the
part and as far as installing it, the shut off for the furnace is at the top
of the stairs, the hot & cold water pipes have spigots to turn them off,
but, I do not see a spigot for the third pipe (I think it goes into the
furnace).

Is this normally a difficult task? I have replaced faucets and electrical
fixtures and can perform small repairs to my car, but should I venture to
expand my list of trades? Binx
