Insulation and venting for a well pump house
I have a well on my property that I need to build a well house for to protect the pump equipment/plumbing and to prevent freezing in winter. The well house with the equipment will be about 20′ from the actual well head. The development my property is in allows for a well house structure to be a maximum of 8’x10′ in size.
My question is how best to insulate the building to prevent possible freeze damage to the pump equipment in the winter (climate zone 5B)? The exterior cladding will be fiber cement siding and the roof will have architectural shingles to match my residence. Can I insulate the walls and rafter bays without any vents in the building or do I need to insulate the ceiling below the roof and have a ventilated roof?
Also, the building will be on a small 8’x10′ slab. Should I use rigid foam insulation under the slab and/or around the perimeter of the slab?
I have been told by a local well driller to install a small cadet heater in the building set for about 50 degrees to prevent winter freezing. Does anyone have any suggestions?
