On many portals, you have to enter your details first before you see what the calculator has produced. We think this is the wrong approach: anyone forced to hand over their number is annoyed afterwards — and the installer who calls pays the price for it.
Our calculators show the result immediately. If you want quotes afterwards, you will find the way there. If not, you have still learnt something.
How accurate are these figures?
These are rough estimates with typical values, not planning results. For the heating load, this means: we calculate with specific values per insulation standard, an installer calculates room by room according to ÖNORM EN 12831 and thus arrives at a more accurate result. For the seasonal performance factors, we are deliberately around 15 % below the data sheet specifications, because test bench values are rarely achieved in practice.
In other words: the calculators reliably tell you whether you are in the right ballpark and whether a quote is plausible. They do not replace an on-site appointment.
