Heat pump Siemens SA 30 P
In front of the company building outside is this 29 kW heat pump. At a heat pump, each degree Celsius teperature difference is important.
With the concept to warm up the underground with the collector in the roof and a floor heating system with extrem low input temperature, there are very low heating costs.
|Heat of earth|
|Your house of apartment is built past 1984? In most cases, You will see, this company building from 1984 has less heating costs per squaremeter.|
|Built 1984 with 24 m² heat collectors on the roof. 2005 had been 153 m² photovoltaic with 21.65 kW peak added. The estimeated yearly yield was 20500 kWh, 2007 was the yield 22400 kWh.|
|Full with water collector system. For warming up the earth collector is also a low temperature enough. Sometimes also without sun, when the air is warm enough.|
|Switchboard for the heat management|
|Original from 1984, this switchboard controlls the heatpump, the 2 earth collectors and the heat collector on the roof.|
|Take not only heat, give also heat. The earth collector as a low temperature saisonal storage. Heat from the 24 m² solar collector on the roof heat up the earth collector.|
|Floor heating is not equal to floot heating. A very uniform distribution of the heat makes a very low input temperature possible. Less electric power demand at the heat pump.|
|Climate controll by the floor|
|The conference room has a large window to the south side. When the sun shines into the room, the floor is direct heated up. A floor heating can take away the heat.|
