No more oil!

It is now official--we are no longer dependent on oil. The furnace is dismantled, the hydronic baseboards have been drained, and the hot water now comes from a new 80-gallon electric tank. The actual heating/cooling unit has also been installed in the basement and hooked up to the wells. Monday the crew returns to cut vents in the family room floor (this was left to the end as it is over a tiny crawl space and running the ducting will be difficult); the kitchen (these will be toekicks due to our cabinet configuration and the fact that we have radiant floor heating there); and the foyer (the old baseboard must be removed first). Then once the ducts are connected, I believe we will be in business!

It is a bonus for us that this company will not only be removing and carting away the old furnace but also removing all of the hydronic and electric baseboards and all of the old thermostats too.

Here are a few more photos:

Big guy is the 80-gal water heater; smaller guy is a 50-gal holding tank for pre-heated water from the geo system.

We had our first 80+ degree day today and it has been pretty humid--this change is coming just in time!

Geothermal/Insulation Update

Wow, it has been a while! Work has progressed the past few weeks, albeit in fits and starts. Holes have been cut in ceilings, ductwork hooked up, wells drilled, insulation blown on the attic floor....Here are some photos:

Creative ducting in the basement

Duct through dining room closet--and we will still have some storage!

Radon system had to be shifted over to make room

Well driller--this is well #1 of 5. Well #5 was difficult--first attempt now has a $2000 drill bit buried at the bottom! Try #2 was fortunately successful.

It's messy work, though the birds have been enjoying our new mud pit.

All the wells are finished and have flexible tubes sticking out of them.

Digging the trench towards the house

The trench, almost to the basement

Attic--the pink is thick insulating foam board, the silver is a duct, and the fluff is cellulose.

New cover for the attic hatch keeping us cozy!
Today the new electric water heater and the desuperheater tank are going in; the unit itself should be here and installed tomorrow or Monday. I'll try to post more photos/news soon!
