CONVERTING MY HOUSE HEATING TO GAS__Good or Bad idea?

Are you saying that you have two boilers, one for heat and one for heating water and that in the winter one boiler does both function but that in the summer, a different/smaller boiler takes over to only supply hot water?



What do you mean by 7 unit? The boiler only has one firing zone but the hot water produce is sent out to 5 zones thru a manifold/zone valve system?

JTT, by UNITS I mean the separate cast metal exchange units in the firebox. The system is a newer Weil Mclain "Gold" (with a german burner cause Weil McLain was having trouble with their made burners in 1999 when this was installed) They are specked by the volumetric space that is to be heated. (We have about 4K + sq ft with 10 rooms at 8 ft and 1 large room with a 20 ft ceiling. A zone is the separate heating task. A zone contains its own thermostat and circulator pump. We have 2.5 baths and a kitchen and laundry with hot water. These are t]served by the separate boiler. (BY boiler we mean a unit . However, all the units are heated by a single firebox and a single oil aspirator and "afterburner"

We burn 0.78 gal/hr for our house on a cold winter day kept at 72. We usually keep it at 68 at night (programmable thermostats) in the main rooms and 65 in the other rooms (Unless they are being used.

glen falls as slightly more severe than where I am...somewhere between your typical extreme winter and summer temps and Glen Falls extremes.

That's interesting, FM. I've never heard of that type of system. Does the firebox/burner move to heat the cast metal exchange unit if only one zone demands heat?

If it was installed in '99, it must have a pretty decent efficiency rating.

Is your concern over standby losses only for the summer/non-heating season or year round? What's the lowest set temperature that the h2o heater can be set to deliver?
