    I have a customer who has a hydronic system where zones will service upper/lower flats. He wishes to meter usage to bill tennants for heating.
    Pictures in my minds eye include water meters or zone timers.
    Any thoughts?
    Thanks,
    Joe

    Would measuring the run time of each zone and then dividing the bill do it?

    The WEL would do that.

    I have seen...

    .....landloards trying to shift liabilty for heating costs to tenants. I have always bailed on these jobs as if the landload succeeds who will pay me? The tenants as I increase their cost of living? I think not.

    I sympathize with the desire to make tenants accountable for consumption. Folks who receive a good or service gratis tend to value it accordingly

    Warm in January? open a window rather than checking thermostat.

    Should clarify:

    Gas fired boiler with iron radiators.
    I think measuring op time should do, or remote stats with fixed temp and heat loss to determine % of load.

    Each unit may have a different heat loss or temperature settings. Are they constant flow pumps? If so, in addition to run time, monitor supply and return temps.

    You know the input gas the boiler takes, you should be able to figure out a "plant efficiency" numbers. Next you can calculate each units consumption by flow, run time, and temperature delta. Divide each apartments use into the input to determine their respective bill. I monitor several apartments for clients of mine that way and everyone is happy with their bills. I have been using HOBO data loggers for this.
