In May 2009 we bought these infrared heating chandeliers
They supply 10kW per chandelier, and together require a balanced supply from a three-phase electric supply.
Although installed in the Spring (so we havn’t yet tested them in the depths of winter), our initial responses are very good: they provide good warmth, fast response times and good heat dispersion. They heat the people and not the dead space. We are very pleased with them.
