2 zone heat, 1 zone gets hot, the other just warm

Hey guys,

I have an electric hot water baseboard boiler that can't seem to get the water over 130 degrees in one zone. The other zone gets nice and toasty within 10 or 15 minutes.
Any ideas?

Thanks very much

This could be due to a variety of things. There could be air in the lines, low water / water pressure, faulty zone valve, etc. A couple of things to do would be:

1. Post pictures of your system so that we can understand how it is setup. Boiler, and piping. (another great help is editing the image in a simple program like paint brush and using arrows and labeling pipes)

2. Track the piping to the second zone. I would imagine that coming right off of the boiler / pump it is probably the desired water temp. But, somewhere down the line (perhaps at a 90 elbow) the pipes will get significantly cooler.

This will give us more insight in order to help you solve your issue.

Sounds like an air blockage to me too...

What does the pressure / temperature gauge on the boiler read?
