Based on postcode, city and region, the form calculates estimated heat demand, system recommendation, energy use, savings and installation cost.
Postcode, city and region are used to calculate energy price, climate factor and installation cost.
If you do not know, select “I don’t know”.
If annual consumption is entered, old/new system costs are compared and heat demand is calibrated to real consumption.
Photos increase the accuracy of the analysis.
This is a preliminary analysis. The final quote is prepared after an on-site inspection.
Energy prices and labour costs are assumed regional averages. If the user enters the real unit price from a bill, the calculation is based on that value. This form is not an EN12831 calculation; final device selection is confirmed after on-site inspection, design and real heat-loss calculation.
