"5 stars is for the best and that's nobody but 4 is already pretty hefty. The heat pump CB-HEAT-11 professionally installed and is performing better than hoped for. Our water was 15 and in just under 4 hours up to 27.5 I like it. I hope it will be as quick as this in the winter periods here. Just a pity I can't find a Dutch manual."
Tony Leroy - Daya Nueva
