I recently purchased a house near Boston. We are doing quite a few upgrades/renovations to the house. Next spring, if everything goes according to schedule, we will be installed 3 WaterFurnace Series 7 units (3ton, 4ton and 5 ton) with vertical wells. It's a large house, and not that well insulated, although every repair we make (mostly water leaks) we bump up the R value when we open the house's roof (slate, rubber, metal). In addition to the geo, we will install an electric boiler to run the baseboards and radiant bathroom heat. Right now, that hot water is supplied by the Viessmann oil boiler which we will be removing. We are planning to install a heat pump in the utility room for domestic hot water. We have a large existing solar farm, and are adding 32kw of Sonnen battery capacity. I am hoping, in the event of a grid outage, to be able to heat/cool and run other household electrical devices overnight. It would not be a problem to turn off the electric boiler in the event of an outage, as the baseboards and radiant heat are not critical. As my username suggests, I am a complete newbie at this. Any words of wisdom are appreciated.
