    Furnace fan + woodstove. What am I overlooking?

    Last winter I self-installed an Ambiance Hipster 20/Hearthstone GM60 wood stove, and it’s been a dream. No draft issues. No complaints. Other than when we’ve been away, we haven’t had to use our oil furnace at all, which is ideal given the trends for heating oil prices. The one drawback of...

    Nest Thermostat 'W' wire connection

    I have an old dual-fuel heat pump system. The "fossil-fuel kit" (which arbitrates between propane furnace and heat pump) appears to be failing.

    Quadrafire 7100 - additional zones worth it?

    We're closing in on purchasing a 7100. One of the intriguing features is the additional ports for additional zones/rooms to be added. Due to our 2 story vaulted ceiling where the 7100 is planned to be located, I have a strong suspicion that our other 1st floor rooms will need some additional...
