What is your current heat source? A new furnace installed isn’t cheap.
We have central HVAC. It is propane.
The unit is a Goodman, and seems to be in good condition.
I have no problem with it other than concern over the ability to get propane when I really need it.
I'm gona be/sound a bit ignorant about your situation, since I don't know your situation, but how big is your house? I guess, my first thought is why an outdoor boiler? If a person has a propane setup already, why not just get a good wood stove and get that installed and have it for supplemental/backup heat? If propane becomes unavailable, at least you'll have a heat source, if you don't already have a stove.
Of course there's variables I'm sure, like if you have a wife and kids or a massive house, or extra money to spend, I understand that stuff would make a difference in the decision.
I guess, I'm a bit of a tightwad though, so the thought of 17k for a boiler install is pretty wild for me. I only gave 17,500 for my whole house though and my house is between 950-1000 sq ft. So a wood stove easily heats my whole house.
Our house is 3500 square feet. 2 story with a walkout basement.
I have a wife and 9 children, so safety and reliability is rather important.
I had an outdoor boiler at our last house and really like the principal of it.
If I buy one, I am not interested in buying junk.
Insurance really frowns on wood heat inside.
I have a place where I can cut my own wood, and we enjoy doing the work.
The propane is really handy, and makes sense to me as far as money goes. Switching to wood is not to save money (although that is always nice), but is more for reliability.
Our government has their hands into way too much, and I don't want to be too dependant if I can help it.
I wish I could just sit a stove in the basement and call it good. I hope to have this payed for in the next five years, and then I can do what I please.
As an aside, I do have a whole house generator that is tied to the propane, and that can provide the power to keep my furnace running during a power outage.
