Not sure which model is right for you?
Correct sizing matters as much as model selection. An oversized heat pump may cycle frequently, increasing compressor wear and reducing efficiency. An undersized unit may not meet the heating demand in very cold weather.
Before buying, use the ECO-TEC heat pump sizing calculator or contact our team for free advice.
