My loft is severely outdated and has plaster walls, big windows and no duct system.
It’s actually difficult to maintain a comfortable temperature.
I’m situated in an section with hot and humid summers and severely extreme Wintertide weather. So far, we’ve been managing the indoor temperature with room-by-room solutions. During the summer, the two of us install portable air conditioner units in the bedrooms and make do with fans and open windows in the rest of the house. In the winter, the sub zero rapidly decreasing temperatures for many straight months are a big challenge. All of us have a natural gas fireplace installed in the bedroom. The heat spreads and can nearly handle demand for the entire first floor. Only the bedroom fails to benefit from the fireplace. To heat the bedroom, the two of us invested in a compact ventless gas heater. This solution is not ideal. The ventless oil furnace is a single-stage unit. It is only capable of operating at maximum capacity. It starts up and blasts heat until it achieves the control component setting and then shuts down. The constant off-and-on operation creates uncomfortable temperature fluctuations. Plus, the unit requires constant maintenance. There are several air filters and even the smallest amount of dust will result in a blinking warning light. When the warning light is blinking, the oil furnace won’t shut off. It runs non stop and I worry about the risk of overheating. I would actually care about to substitute the ventless oil furnace with a ductless heat pump. A ductless split system would mount up high on the wall and provide both heating and cooling capacity. The newer models feature inverter technology, allowing the component to adapt capacity to exactly meet demand. The ductless heat pump would maintain more even temperature and cost less to operate.
