Has the HeatingSave Building Energy Management System saved AH Garner money on their energy bills? "Yes it has!", said Mr. Lewandowski. He added, "We have only had a few winters since HeatingSave was installed; but I was looking at our spend over the last few years and we were typically spending over £20,000 per annum on heating. In the following years, we averaged £23,000, and then after installing HeatingSave installation, our bill was down to £17,000 per annum". This was a 26% saving, with the system having only been active for half of the winter.
