15Kw Heater

Its been too cold most days to get into the main workshop and do any work, so I took the plunge and purchased a 15kw 3 phase heater. I know its not going to heat this place up, but it takes the edge off of the area I'm working in. I worked out we would need about a 40kw heater for this unit, but with no insulation it would probably need to be on continuously! This 15kw unit was reasonably priced at £175 and was about the biggest I can plug into our 32amp 3 phase socket.
