Ran a project in an old building, not so well insulated office/print room in Wexford. Installed two 60x120 Sunnyheat infrared panels in two adjacent rooms, one in each room. These panels were set at 18 degrees during night and 21 degrees during the day. Started measuring at the 2nd of June 2010. The Sunnyheat panels used up to 1st of September 2010 resp. 79kWh, 123kWh, which totals 202kWh.
The night storage heaters that heated these rooms before came on every night and used in the same period last year: 6kWh * 6 hours * 5 days * 8 weeks = 1440kWh.
This saved our customer 200 euro in the space of 8 weeks!!!
