We have lived here for about 5 years and the heat has always behaved

The house has FHW by Oil, 3 zones: First Floor, Second Floor, Workshop.

There will be a zone control valve for each area.

Thank you all for the info. *I took a look and could not find zone valves
in my system, just a type of one way valve at the beginning of each run..

this. *One was bad and he replaced it, so all works now.

Thanks again.
