Install register with fans above Harman P68

[96P993]

We just finished installing our P68, was coming up with ways to get more heat upstairs...Above the stove is a 2nd bedroom, my thought was installing a register with fans to suck some of that heat upstairs. Has anyone done this (I searched) in order to get some of the heat moving and are you happy with the results?

TIA

Check with your fire service; it may be illegal
Vents like that tend to be chimneys for a fire

Never thought about that one...Will do some homework

In my case, with a P61a, vents, vent fans, and other fans did not help regardless whether I had them going up, down or sideways (and combinations). aFter install, I cut in several registers in my beautiful wood floors (the best feature of this 1960 house). Even with the basement at 90*, the warmest place on the main floor was in the mid 60s (room next to the open stairway) and the bedrooms were in the low 50s. Basement is 640 sq/ft and main floor is 950 sq/ft, so the P61a, on paper, should have easily heated the entire house.

After the first, very noisy winter from all the fans, I put a St. Croix Hastings on my main floor. That was a corner install (because of clearances), and even with fans into/out of bedrooms, the living room was hot and the bedrooms cold (although at least they were in the low 60s). After that 2nd, fairly noisy winter, I found the P43 for an incredible price. That allowed me to place the stove so the air stream was directly down the hallway to the bedrooms, and removed all use of auxiliary fans.

For other people, no extra work or stoves are needed to warm their whole house. For others, just a couple of registers for rise and fall of air. It all depends on the dynamics of the house. My house, although small, is very cut up with a bunch of small rooms. there is absolutely no notion of an open-type concept, and the hallway and stairway would not be a legal width for a residence built today. So my house has extra hurdles that I had to overcome.

I have an Absolute 43 and installed a vent in the ceiling (attic) with an insulated box, insulated flexible duct work, and an AC Infinity Cloudline Pro T6 fan. It pulls the warm air from the room with the pellet stove and distributes it to two other bedrooms where the heat just naturally couldn't reach. The AC Infinity I purchased has a programmable controller where I can have variable fan speed up based on temperature. Installed the vents, ducting, and fan last Thanksgiving and it made a tremendous difference in keeping the two bedrooms warmer.

Stove placement is critical to getting the heat where you want it to go. You've already got the stove installed, so now you have to deal with it...

I opened up the vents from the forced hot air system in this house to let the heat up from my basement install. I pointed the stove at the open stairwell. The heat went up the stairs, the cold came down the stairs, and some of the cold came down the vents. I never felt heat coming up through the vent holes. I did notice the floor immediately above the stove would get warm to the touch, but I don't think it was enough to change the temperature of the bedroom. If you opened a hole immediately above the stove, that would probably help in that room, but as mentioned, you're taking a risk by doing that....

When running fans you just want then on a low setting, enough to move the air but not fast enough to cool the air down. I now have a little 8" wall mount fan in my hall way on a sleep mode setting and it made a difference on how fast the back room heats up.. Put it on any higher speed and it actually takes longer.

I installed a P43 in my basement this year. Soon after that I cut a register hole in my bedroom which is directly above. I used 4 inch duct. I should have used insulated duct in hindsight. I had a cheap fan, but just installed a new AC Infinity one that has brushless speed control. I suck the cold air down, and it comes out in back of the stove where it gets sucked into the room blower. The the hot air is drawn up the basement stairs in a circulation. It is noisy, but not too bad if the fan speed is turned down. I called my city building department and in my case he said that was no problem. If I was cutting into my garage ect that would not be allowed. Having a hole in the floor inside a house with open doors and stairs ect should not be a problem but confirm with your responsible authority. I ran the stove 24/7 in the cold weather so I could shut the heat pumps off. I have electric convect heaters also to take up the slack. I posted some stuff on here when I did it.
