Turns on about 5pm turns off at 9:30am - 11:00am
If we have the fire going it will turn about 9:00pm.

865277 2010-03-11 04:01:00 The dude said in winter it might be 3.9 degrees when you wake up. The HRV system raises the temp to 16 so you need minimal heating to get it to 20 degrees. He says in winter there will be substantial heating up in the roof space.

For the 60% saving power bills, it is also in their brochures, he says NZ universities research has proven it. And that HRV sells the most in Southland and Otago and that Otago uni recently installed 50 student flats with them in it. :clap


You will need him to put that in writing, because that sounds impossible. Where is that heat coming from, because the rook space doesn't magically create heat, and in winter the roof space is often almost as cold as outside, as the roof space is not insulated from the outside.
Do they actually have this university paper to show you to prove those findings. They maybe taking the figures out of context. Maybe they said 'up to' 60%. Our DVS certainly doesn't do any of that. SOme brands have heater attachments, but it costs more to run those, and it is more efficient to pump heat in from the floor, due to heat rising.
