The graph below shows the print room temperature and humidity levels in October. The Sunnyheat panels maintained a set temp of 20.5 Degrees (DAY AND NIGHT) and used 730 kWh of electricity in the process while reducing humidity range. That’s an energy saving of 46% over using storage heating, which is not controllable or effective. The cost saving is estimated to be 80 cents a day although in the summer the saving was €3.80 per day. The Sunnyheat panels have a fully programmable remote controlled thermostat and the long wave rad iant heat does not heat the air but rather the fabric of the building and its contents. As the surface temperatures are higher the air temperature does not need to be as high in order for thermal comfort levels to be achieved. Storage heaters primarily heat the air which is easily lost in a leaky building. The operator is very happy with the comfort levels in the print room now. The Sunnyheat panels are designed to replace tiles in suspended ceilings. http://www.sunnyheat.ie/
The graph below shows the storage heaters and convection heaters in Dec 2009, the temperature in the room struggled to get to 20 Deg and the humidity was all over the place.
