Browse Forums Heating, Cooling & Insulation Re: Ventilation in bedrooms with dual glazed windows 20Jan 25, 2018 11:57 am =) don't think you would be able to sleep next to the crypto mining rig =) Heating burns oxygen and uses a lot more energy than HRV system does. Don't forget that with open windows comes noise as well. For heating/cooling of the bedrooms I use nothing currently. Just insulation and the temperature of the house. For pure ventilation purpose I could use a heat transfer kit to drive the air from another part of the house. Most likely be the living room that has an aircon/heater. But to add a bit of fresh air, I would add an in wall HRV like http://www.fantech.com.au/images/Brochures/Aerofresh.pdf - does 60m3/h on high setting but only uses 7W with heat recovery of 80%. I think this is really good in comparison to the heat loss/gain with having a window open More expensive option would be to add ducted AC and have it drawing air from the area where that in wall HRV unit is, so that fresh air is added to all the rooms I don't know them all, the first 2 top of your list are best known.
