How long into winter can we run our Heat Pump with our Legalett System

This is a good idea, as heat pumps can be up to 3 times more efficient that other heat sources. We consulted with a Legalett engineer to be sure, and they would like you to run your Legalett air-heated floor system at least a bit to inject some heat for proper frost protection. In order for it not to compete with the heat pump, you could set the floor at a higher temperature just to activate it, just be sure to set a reminder somewhere to turn it off again so you don't overheat. This is something you could do for a few hours every few days perhaps. That way you can use your feet as a judge for when the temperature has risen slightly. It doesn't need to be run so much as to heat the air of the house {the heat pump can do that) but enough so your feet are a bit more comfortable.

Legalett has required minimum operating temperatures for each custom design, either 18C, 15C or freezable like in the case with an unheated  garage, and freezable slabs have significantly more skirting. Do you know the base operating temperature? If not you could email us your address (info@ecohome) and the Legalett engineers have offered to confirm if you aren’t sure.
