Energy savings calculator
Kömmerling has launched an energy savings calculator to its website, which enables consumers to estimate the cost and carbon dioxide savings of installing certain types of window including 58mm, 70mm and 88mm frames.
The energy savings calculator takes into account the total window surface area, type of windows to be replaced, proposed new windows and estimates their U-value. Once this has been established then users can input their choice of heating material used and the price per kilowatt, the calculator then adds a nominal annual price increase. The results are then calculated showing the savings in year one in terms of money and carbon dioxide reductions and this is then extrapolated over 20 years.
A typical house with 25m2 of glazing with first generation PVCU double glazing upgrading to a new five-chambered Kömmerling C70 or O70 Gold system would make significant savings, with the resulting reduction of over one tonne of CO2.
