Good Morning.
12° with a high of 20 today under a clear sky.
Yesterday’s snow removal went well, just did my place and son’s, as he was out of town, but DIL and grandson were home.
When I built this place almost 40 years ago, I was obsessed with making it as energy efficient as possible. That meant no fire place or chimneys, a complete envelope of sprayed in urethane insulation foam from under the basement slab to the attic. Its heated and cooled by an open loop geothermal heat pump with no back up, as none is required for an open loop system, the ground water is 55° regardless of the outside temp, and is of virtually unlimited capacity (the geo loop, not the system)
The result has been exactly as planned, the house is extremely comfortable with consistent temperature throughout. I have averaged about 15 years out of each heat pump. Each one has benefited from advances in process control and become more efficient, and using less water.
However, I’m planning on putting a fireplace in my new “in law suite” that will become my new home. I like tending the fire and the radiated heat, even though I realize I’m sending conditioned air up the chimney.
This will be on a slab, which I plan to heat with propane warmed water to break the ground chill, but use mini splits for overall heat and AC. The advances in efficiency of the mini splits take away a lot of the advantage of going geothermal.
I now have the township approvals and exemptions that I needed to move forward with the project, so now I’m doing the design work. I’m will be hands on, but I’ve decided to actually hire a general contractor to run the project. I’m confident that we can work well together, allowing my level of involvement to vary without impeding progress.
