Dunelm Plug in 500W heater.

[jovad]

For anyone requiring a small heater to maintain the internal temperature in a PVC or small motorhome when on EHU, I can highly recommend this tiny 500W unit presently available for £15 at Dunelm. I had occasion to stay overnight at Cornish Farm this week for solar installation and having drained down everything for winter storage I needed a small fan heater or similar to keep me warm throughout the evening. This little thermostatically controlled heater can be adjusted in 1 degree increments downwards from its default 30 C and even has a timer to select on periods upwards from 1 hour. You can even change its orientation by 90 degrees. Possibly insufficient in freezing conditions. I suppose it all depends on the internal insulation of your vehicle.
