I have a 3 story 12 unit apartment bldg. and it is currently heated by nat. gas boiler hot water with baseboard copper pipes ..each unit has a thermostat to control their unit heat. The problem is when it is in the 40 to 60 degree range, it is difficult to please all the tenants. If I turn on the boiler when it is 50 degrees roughly, some tenants will open their windows even though they have their thermostat off the heat comes from the other units I guess. If I wait til it's 40 roughly then some tenants say they are cold. I think the system is not efficient and I have to monitor it too closely. A tenant may move because the heat is not the temp. that they prefer but not say anything to me so that I don't know the reason they are moving. I hear other landlords replace boiler heat with baseboard electric heat. each tenant can get exactly to their liking, and if one unit has a heat problem it would be for one unit only. Now, if the boiler/ pump fail, allunits are cold and that m,akes me nervous....any advice about the change over is much appreciated. Each unit has 60 amp circuit breaker service; is that enough for elect. heat? Can the baseboard covers be used for electric baseboard housing after removing the copper plbg? how much will this all cost? any other way to individualize any type of replacement system? thanks a ton to all!
