We visited this car workshop in Sutton. It has 5 roller shutter doors running along its entire length, an arrangement makes conventional heating virtually impossible. However our shortwave infrared heaters controlled by time delay switches, will keep the staff happy and running costs under control.
My husband takes pride in his boat. He is all for buying quality items and is very picky about keeping them nice. During the winter months, he doesn't settle with a boat cover, he makes sure to rent a boat storage unit to keep it from weathering.
