QUESTION FROM tom

we just put in a brand new house and have an ouside pellet boiler and it does not seem to be heating the way it should on cold days the temp does not get above 67 degrees we have been moving pipes around trying to get air out nothing. the pipe entering the baseboard is hot along with leaving the baseboard any thoughts?

ANSWER FROM HOME-WIZARD

Dear Tom:

It sounds like you have a baseboard hot water heating system that is heated by a pellet boiler, and you are not able to get the temperature in you home up high enough.

You said that you have been moving pipes around, but have you tried purging the air out of each zone of your baseboard heating system? For the procedure on how to do this, please see the answer I gave to an Ask-the-Wizard question on this earlier today.

Other potential causes can include:

1) bad (or improperly adjusted) thermostat.
2) bad circulation pump.
3) valves not open all the way (which reduce circulation rates).

However, if I understand you properly, when you say that the pipe is hot LEAVING the baseboard, if you mean that the water being returned to your boiler (after going through your baseboard radiators) is still hot, and that this is a NEW house, then I'm wondering if possibly the amount of baseboard areas in your home are not sufficient for the area of rooms that you are trying to heat? In other words, that there should be more linear feet of baseboard radiators, or that they are augmented by an electric blower (which is sometimes down in kitchens or bathrooms where there is not enough wall space for enough feet of baseboard radiators).

Hope this is helpful.
