You use air circulation from your heat pump don't you Slim, or am I misremebering what you wrote?
Nicky, I agree about temperature. I have great difficulty sleeping if it is too hot, and am used to working in cooler temperatures. When I worked in clean rooms, we had to keep the temperature and humidity fairly high as most of the work was carried out sitting very still, and higher humidity was better to reduce electrostatic problems. If I had to do anything physical, such as cleaning, I got overheated, and couldn't take off a layer, as we had to wear special clothing.
We keep our wood burner running all the time in winter, and although it runs down overnight and the temperature falls, it is still going in the morning and needs to be just 'woken up'. If necessary we add a little smokeless fuel to keep it in. We shut the bedroom door if it is too hot when we go to bed, but try to shut it down a little while before going to bed so that it cools down a bit. |

I've written about it before, but I can't remember what thread.
We bought the place with a defunct outdoor wood boiler, hooked up to leaking plumbing for baseboard hot water radiators in the first floor (must have frozen? I cut out lots of burst copper pipe and rusty radiators). Living room also has a small functioning propane wall furnace (Rinnai). Upstairs was completely unfinished (loose subfloor and bare external stud walls). House was about 20 years old when we bought it.
We put in a wood cookstove and a mini split heat pump in the dining room.
We heat primarily with the stove (no water tank or hookup, JA Roby 'marmiton'). The heat pump is constantly circulating a very small amount of air to judge the temperature, this helps to circulate heat around the house, but only to a very minor extent (you can't even hear a the fan moving). When the air temperature finally drops below the heat pumps set point (usually early morning, depending upon outdoor temporaries and how late I put last load into the stove) it turns on, and starts blowing warm air, and that circulates around the house pretty well, blowing into the living room (past the stairwell where heated air rises on its own), and around through the back hallway, ending up in the kitchen and finally back to the dining room. Because they're in the same room, the heat pump is actually set pretty warm - to kick on at about 70 F. The air is pulling in is from near the ceiling, so it's usually quite warm there if the stoves been used. By the time it kicks on in the mornings, the colder rooms in the house are probably in the low 60s F. The thermostat can be adjusted very easily, so I drop it down when we're leaving those for a couple days and let the heat pump handle the whole load.
We kept the propane heater in place, and turn it on for the coldest nights (starting when the outdoor temp is forecasted to be below about 15 F maybe) when the heat pump doesn't put out much heat. Also leave it on as a backup when we're away for a couple days during the coldest part of winter. It functions similarly to the heat pump, circulating a small amount of air to gauge temperature and cranking up when temp falls below it's set point, but it's "downwind" in the circulation of air.
So the great pump and the propane always circulate a tiny bit of air (probably not that noticeable) and really push some hot air out when they're running, but each is like a large space heater in a sense. No ducting, apart from the flexible refrigerant lines connecting the two end of the mini split heat pump, and the gas and exhaust on the propane heater. The majority of our home heating is moved via natural convection |
