Hey Blew I run a Harmon. Almost trouble free for almost 15 years. One main board and one igniter in that time. They make a great product.Lights cost more than sun, but I do it for my mental health...it gives me a winter project and I love to see something green and happy in February
We were lucky to get our hands on a Harmon pellet boiler before the FDA made them stop production (just fell short of the crazy low emission requirements, which is hilarious when you see a neighbors outdoor boiler burning trash!) It heats our floors, radiators (only when it is below 0F, which is rare) and hot water. We go through about $1250-1500 a winter in pellets, all sourced in Maine (or Canada). Pellets are carbon neutral and the money stays local versus fossil fuel $ going out of NE.
We use a wood stove at our cabin and I love sourcing and prepping the wood as well. My 10-year son is learning the value of a good days work when he helps me. Plus, I am surrounded by enough timber to last several lifetimes...pellet production is a complex process, and they need to be delivered, so if that supply is ever disrupted we have a wood cookstove as well.
Please have a great Christmas.
