Hi Thomas
I bought an SV30 from you a couple of years ago. I have just had some craftsmen doing various jobs on my summer house. They worked there in December and January and were very surprised by the fresh air in the house. No stale old summer house smell. I, myself, have now worked there for several weekends. The sky has been clear most of the time and the SV30 has blown fresh air with a temperature of 46ºC into the house when the outdoor temperature was 3ºC, that is an increase of more that 40ºC.
We have shut off the heaters on the days when the sun was shining.
Kind regards, Olaf West, summer house in Soendervig.
