Baseboard Heating Too Long To Heat

The Home Wizard app calculates your ideal home care program to avoid problems with your Baseboard Heating, but sometimes trouble can still occur. Here are answers to questions about baseboard heating too long to heat.


I have a 5 zone baseboard heating system. My question is it takes a very long time to heat up the zone i.e. one zone is for the family room (20 X 14) and it takes up 3 hours or more to come upto 68 from 60. I did vacum (even though it was not easy) and tried to remove any dust from the fins.


Dear Raman:

If with your 5 zone baseboard heating system only one zone is not working well, one question is whether this is a new problem, or is it something that you have always had a problem with? In other words, is it a system design problem where there is not enough hot water supply to serve the size of this zone of your house?

Assuming that this is a new problem, here is a list of potential causes as to why this zone could be taking so long to heat up:

1) the zone needs to be bled of air.

2) your circulation pump for this zone has gone bad and is not circulating enough hot water.

3) the check valve in this zone is partially stuck, and is reducing the flow rate of hot water (you might be lucky enough to solve this problem with some raps on the valve with a piece of wood, NOT a hammer).

Hope this is helpful.
