Seeking Ideas for Replacing Baseboard Heat
We have a property in Zone 6A that contains two buildings – one is a 600 sq. ft. studio, the other is a one-bedroom 1000 sq. ft. house. The studio is heated with a kerosene boiler, the main house uses heating oil; both drive hydronic baseboards. Both buildings are single-floor, circa mid-1960s, and have tons of double-pane glass and foam-board insulation (I believe it’s R5), thus there are baseboards all over the place.
I’ve looked into the following options for each:
* LP combi boilers – Viessman or perhaps IBC
* Mitsubishi Hyper-Heat Mini-Splits, w/floor-mounted handlers
I was initially going to go with the combi boilers, but the price of propane started to scare me, as well as the fact that I’d need to have four very large bottles outside, which is an eyesore. It does address the problem with DHW, though, which is an issue since the studio uses the boiler for it (the main house has an electric hot water heater).
I’m leaning heavily toward the mini-splits for environmental and exterior aesthetic reasons, but I really worry about how well they’ll work in practice. The fact that you need to have a backup heating source is making me a little nervous, especially because I’d really like to get rid of the old boilers and fuel tanks.
Is there a better option for heat out here? The two buildings are very close to one another (maybe 30′ between them), and it would be amazing to have some sort of shared heat and treat the studio as another zone of a larger heating system. I don’t know much about Chiltrix, but that sounds like it could be an interesting alternative to the Mitsubishi unit?
