Looking at moving heat from fireplace to the hallway which is only around 6m away. Don't want an HRV type system but a room transfer kits. Anyone used these and can advise/review. I see there is fan and fanless ones, any recommendations? Just trying to push hot air to the cold part of the house.

need a fan for sure. i think there is a post about the mitre10 ones recently.
make sure pipe is insulated and even cover it with more insulation. otherwise you loose a lot of the heat into the ceiling. also need to think about air return path. i read an article recently that said they need about 100mm cut off the door for the air return to work properly. but as your fireplace is sucking in heaps of air from outside anyway, its probably not a big issue. if you have looseish windows they will provide enough gap for air to be blown out at the other end of the house.

buy a kit with a thermostat too.

you don't need 100 mm cut off the doors, that's rediculous.

yes it is ridiculous. actually i was wrong. the article said 300mm off the doors to avoid pressurizing the air. but thats with central heating which will have a bigger fan and a very well sealed house.
but i think the point is made. think about the air return.

wth? No. If there are doors in way the air would flow from the outlet to the fire you just leave it open a bit.

The heat transfers I've installed typically go down to 150mm ducting at the outlets.
cross sectional area of a 150mm diameter duct = 17671 mm2
To match this area with a gap under a 760mm door you need a 23.25mm gap under it or even better leave the door open.

just a mad thought.
op is looking to put outlet in the hallway. is there any point to that as it may heat the hallway up a bit but its not exactly going to heat rooms up unless you can get air flowing from hallway and into the rooms. even then one outlet is not a lot of airflow.
would a return back through the hallway door be needed? with a single outlet feeding the rest of the house, its probably got enough air leaking past windows in all the rooms to not require it.

If you push air into the hallway it may naturally flow into bedrooms anyway due to leaky windows. Worse case scenario could be air flow from outside into kitchen via rangehood, into lounge, thru heat transfer system to hall then outside again thru bathroom exhaust fan. Is definitely better to duct into bedrooms, works so much better.

i'm just wondering where all the air for the fireplace is coming from

From within the room, hopefully being replaced from outside. There have been people killed in small cabins because of a fire used up all the oxygen.

was thinking more along the lines is the air being sucked in past the windows in the lounge only, all the windows, through range hood vent, door etc. now add a transfer kit, if you have a return via hallway door is that going to mean air gets sucked in from all the rooms which may partly defeat the hot air being transfered down there. or do you seal the hallway door and let the transfer kit blow air out the other room windows, which would increase the air being sucked into the lounge.
I have one the same as this link, have moved house and never installed, will be listing on TM for $1 reserve in the next few days

I've installed a 3 way in my house got it from bunningsd works brilliantly and nice and quiet too. It came with a fan motor placed in the ceiling and I fed the pipes off to each room.

We did it and dropped it in the hall just outside 2 bedroom doors at the end of a hall and it made a decent difference to the bedrooms. It did have a fan.

We put one in, with a single 6 metre tube to a hallway outside two bedrooms. We have a new home with a gas fireplace that is direct vented through the wall. Our problem was that the lounge gets too hot even on minimum setting. We have a thermostat and it does move heat but not massively. Ours was from Mitre 10.We don't close off rooms in the house as its pretty warm anyway so we don't have to worry about the lounge walls being sucked off the frames lol.
