Hey I was just wondering, my house is 1200 sq ft. It's a prestige mini home, and well insulated. Right now I have a LG 18000 BTU Multi Split Heat Pump, and it heats pretty good. I live in Nova Scotia, Canada in Zone B. I was going to get a bigger unit around 24000 BTU's to heat my home warmer when the temperature drops. Do anyone think the bigger unit would heat better, or should I look into another form of heat to use when the temperature drops. On our coldest days, my current heat pump maintains 21 degrees celcius in my house, but my wife likes it around 23 or 24.
