My wife and I are closing on an 1830 Clonial similar to "Bedford in SN33".
Clatboard exterior, no insulation, and lath and plaster interior.
I already know not to insualte because we do not have a vapor barier, and it will create a moisture pocket and cause damage to paint and rot the studs. It is not in our budget to remove the clatboards and install one.
We have very ugly baseboard hydronic heaters. The boiler is shot and the existing chimney has leaks. Instead of installing a new sleeve and new oil tank we decided to go with a gas boiler. Then the can of worms opened when i was asked "why dont you put in a heat pump?"
There is currently no duct system. I can easily run flex vent through attic and basement to all 1st and 2nd floor rooms. The we can get rid of baseboards.
The attic is insulated and we are planing on sealing gaps all over the house.
My question is. Is a heat pump an efficent heat source for our 1830 un insulated home.
