-We are in the process of planning our own home. It will have an area of 135 sqm (1453 sq ft), 20 cm (8 inches) thick insulation, and triple-glazed windows. According to our architect, the house will qualify for a KfW 70 subsidy. A ventilation system with heat recovery is planned.
For heating, an air-to-water heat pump with a supply temperature of 40°C (104°F) is intended. Would it possibly be more advantageous to pay an additional 1500 euros for a pump with a 35°C (95°F) supply temperature? Is it worth the investment? What annual electricity consumption should we expect to budget for?
