1 Boiler - 2 Zones - 2 Bills
So, I get a phone call today from a customer who owns the store front attached to a 2nd floor apartment. The landlord just had somebody replace the boiler. The landlord wants the store owner to pay for 66% of the gas bill even though they use the least amount of heat (freezer compressors dump a lot of heat into the store).
So, I had this vision of splitting the gas line to the boiler with separate gas meters and solenoid valves that would be energized by the individual zones. Does this sound practical or possible? The piping would have to be symmetrical to be accurate. Do you think, if both solenoid valves are open at the same time, that the meters would read the same CFH or the total CFH divided in half?
Most importantly...is there an easier solution? I've been researching BTU meters for the hydronic lines, but (hate to say it) they are damn expensive!
