I am about to set the rear header for the ceiling of the Garn on the outside wall, I want to have a 4’ wide access panel from the outside for inspection and service if necessary this will allow access to the supply/return as well as the air intake and the flue.
I have looked at photos of other installations and notice that on some the ceilings are higher than the manhole with a framed opening which I think is a good idea for additional insulation
.
Is there a point of no return on how thick to make this blanket? I do realize you have to be able to reach the manhole and anodes. In a house the heat loss is greatest near and at the ceiling.
Those that have already done this, do you now wish you had added more insulation above the unit?
Perhaps I am getting too anal on the insulation but I would like to cut my standby losses as much as possible.
