I have a well sealed 15 year old house with double glazing and good insulation but get considerable condensation around my aluminium joinery as it isnt thermally broken. Heating is currently provided by a 8.4kW heatpump in the main living area which keeps the house warm (but distant bedrooms take ages to heat). Downlights are LED and well sealed.
I am looking into getting a Cleanaire to get fresh air into my house and help with the window condensation issue. Hopefully it will also help with the heat distribution to the far rooms. I plan to have it running constantly at a low speed.
A couple of questions for people with similar balanced HRV systems..
- Do you find that you lose a noticeable amount of heat from the house into the roof space through ducting lengths and heat exchanger efficiency? Ie, in winter is your house noticeably cooler with the system running and do you require additional heating?
- Is there a company who makes a heat pump unit without fans that could be added to the system if I decide I want additional heating/cooling at a later date? Basically like the inline electric heaters you can get
