I have added on to my house and am looking for a very efficient heat source. I am setting it all up for radiant in-floor heating. HEre is the deal:
I have a monitor now in the current building, works great, runs on K1.
I have Propane available, no Natural Gas
I have done the math, and because propane is so expensive, it never seems worth it to run that vs K1.
I worked out the heat load, so that I should need about 60kbtu to heat the addition,[~800sqft living, 1ksqft garage] although it hit 8 below last month so I may want to re do that.
My current thinking is to get an oil fired high efficiency furnace for the addition, and either size it for the hot water, or get a separate tankless hw unit, bosch for instance.
I am not afraid to spend some on the furnace, but head to head comparison seems difficult.
If I am going to spend extra on the furnace, I want it to be durable. It mus tbe over 85 percent efficient or the cost of the K1 will break me.
