the reason the dessicant ones heat slightly is because the fan inducting the air in has silica gel pads on it. The gel absorbs the moisture out of the inducted air and using centrifugal force, flings the water out into the water container. A heating element dries the silica pads and the warmer air is exhausted out of the top at around 12c.Interesting
Will be a piped radiator so will just heat up when house heating comes on hopefully should just keep it nice an warm.
God what a geek I sound. I’m a right laugh out on the beer
