Sturbridge, Massachusetts — electric boiler
Sturbridge, MA. Have abundant PV, similar to Ed Jones’ question. Need electric boiler recommendations. 40 panel ground mount lease. Put in at the height of recent depression. VG deal.
Property has small slab, under 900′ sqft,, 3” foam under and sides. low e glass, 2×6 walls.
Have abundant solar PV, no electric bill, even this winter. I do clean the panels after storms.
Current fuel is wood, we do not need to discuss.
I would rather use up more solar electricity, instead of sell it back to the grid.
Standard HVAC guys, really cannot grasp this. Most go right to propane ..
The slab is a great flywheel and I am addicted. Once warmed the temp differential of circulating water averages only a 2 degrees or less …. slow to take and release …
Need recommendations for electric boilers and whether a buffer tank should be used.
heat loss estimate 20k BTU (2 of the hvac came up with that #) –
My thought is 6kw? to 9kw ? Brands?? Cost Estimate?
If there are other ideas, please advise.
Because of building design I can isolate a HPHW heater and not be stealing from myself.. from a 1000 sqft basement adjacent… leaky and damp, unheated and always at 55 degrees.
I realize we can go straight to Minisplit and get AC but am hesitant, the slab is like have AC in the summer.
Thank You – Howard
