The installers of the geothermal system, Jeff Gagnon heating, arrived at about 10:00 Monday, later than expected because they had trouble locating our residence. As they arrived the well rig had already been removed, and Goodwin’s will come back Wednesday to test the water and hook everything up — and we’ll be back on our well water. After a walk through to determine where the ducts would be and how they could reach the basement through some of the closets, they got started.
The equipment actually turning the heat into forced air is going to be located in the attic and that presented two problems. First, the hole for the attic is small, and they ultimately couldn’t get the unit (which in theory had 3/16″ clearance) through. They had to take the unit apart and reassemble it in the attic. They have a crew of four people doing the work, and they were friendly and professional — just like their boss.
Even though Maine has pleasant temperatures — today in the seventies — Maine attics do not. It was extremely hot up there, so by 11:30 after they’d finished the arduous task of getting the equipment up there they needed, they decided not to work up there the rest of the day. Instead they’d prep the materials for the rest of the house, put some holes through the floor where pipes would go, and then arrive Tuesday at 6:30 AM so they could get work done before the day gets too hot.
Today they located places in three closets where they’ll put pipes running to the attic. The largest will take heat directly up to the attic so it can be dispersed through the house. The others will try to give as much heat as possible to the basement, though we will at times have to augment that with our oil heater or electric space heaters. We may use the later more often since the basement is one zone, and most often in winter we’ll just use part of it. Time will tell. The oil burner will still be used for water, though a desuperheater will give us plenty of hot water in summer, and be pretty efficient in winter. It’ll be very interesting to track oil usage this year!
I had to make some decisions — where should some vents go, can they place the heat exchange pump a more convenient place than originally thought. Mostly I just deferred to their judgment — they are the experts. They were very good at explaining what they were doing and why.
The garage now holds the heat exchange pump, duct work, and the 18 vents (plus two return vents) that will be installed over the next two days. So though not a lot was done today, I have a clearer picture of what to expect, and it’s pretty exciting.
For those who read this blog for my reactions to politics and world affairs, I apologize that I’ve sort of turned my attention away from all that thanks to Italy and now this home project. During the school year I have to keep up on all the international stuff because it’s part of my courses (and yes, I do find this to be a fascinating world!) And at the end of this month I’ll be teaching summer courses so I’ll re-engage!
