Question for a plumber on a forced hot water system

[Steve K]

Raven,

I cannot get to the pipes to insulate them. Good point about the valves. Unfortunately, I have no way of knowing if there are any valves.

Thanks,
Steve

look at the heating unit....
and see what it is...

then relate your finding...

it may be set to low...

they usually can be reset with just a screw driver

Is this radiant or baseboard? if it is radiant you don't want to go much higher than 140 on the mixer if you have hardwood floors and there should not be more than about 15 degrees drop over the run. I cant remember what the drop if for baseboard tho. if there is there may be another problem.

I have baseboard and hardwood floors. It is less than two years old. Is it normal to hear the water rushing through when it kicks on or does that mean that there is air in the system?

No its not normal. Sounds like you h ave air in the system that is restricting the flow. do you have bleeder valves on it?
