Having used the heaters you supplied, during the coldest winter for 10 years, I am pleased to inform you that they performed very well under extreme conditions. The running cost compared favourably with my previous heating which was solid fuel-based. Also, the ease of control with no maintenance required, compared to having to empty and top up a solid fuel burner was a definite advantage. I should like to thank you for the care and attention you gave us, dealing with the order and supply of the heaters.
