Oz07 Posted February 13, 2021 Share Posted February 13, 2021 What temp do you lot have your frost protection setting at? Mine is apparently factory set at 1deg c but I am sure I have seen it not come on until 0 deg c I want to knock it down a few degrees as I suspect this increases my heating loss due to the way the frost protection works (unbalanced?) I suspect having a relatively cheap unit - Domus HRXD - I am safe to go down a few degrees as it wont be the most efficient unit (upto 86%) on the market anyway?

MJNewton Posted February 13, 2021 Share Posted February 13, 2021 What's the setting actually a measure of? The reason I ask is that on my unit it can't be adjusted (not even visible) but it's never kicked in despite the outside temperature regularly sitting at -4C. I've put this down to the fact that the exhaust air in those situations has been, say, +6C and so the heat exchanger itself is still sitting above zero hence not at risk of frosting up.

Oz07 Posted February 13, 2021 Author Share Posted February 13, 2021 Just says factory set of the incoming air at 1deg although can be set down to -15 I think Link to comment Share on other sites More sharing options...
