Looking to add something to existing on-floor drying to keep the humidity at the right level so I can turn the fan on and leave be. Fan is big and old-school, so really I want to set it going and have some kind of gas burners modulate to keep the air nice and dry. Anyone seen anything different / better than a Tryac burner and couple of humidity sensors? Do you reckon I can get some in and fit for £4k or abouts?
