Customer testimonials
Having examined the range of pellet boilers we decided to purchase the strongly built, efficient, high quality German constructed KUNZEL-25. Since installation in December 2006 the boiler has been operating daily, at an amazing cost of £10 per week over a period of 18 months.
We are completely satisfied with the system installed and the high quality of personal service given by Mr. John Kielt of Modern Energy Technologies.
