Oxford study proves heat pumps triumph over fossil fuels in the cold

This is a most excellent place for technology news and articles.
Mind me asking what yours cost?
Just got a Toshiba unit installed in Norway and it was $3500.
Built in de froster.
Price might be what makes yours strugle in colder temps.
Mine has Toshiba guts. I don't know what I paid for it - now it appears to be selling for $1100. Mine defrosts but its defrost cycle just turns on AC for a bit instead of heat. Edit: Mitsubishi guts.
I reckon that’s your main issue.
You’d need a model designed for a colder climate.
Maybe for your next one!
Hell that's cheap.
Cheapest quote I ever had was £15k, not including all the improvements to insulation required before the house is compatible..
Mine is air to air.
You were probably quoted ground to air, where they must drill for ground heat?
