Can you leave a Legalett slab in winter in Canada without the heat on?
Hi, Planning a home in rural Southern Ontario (Zone 6A). We want heated slab on grade but are concerned about preventing seasonal issues esp winter. Legalett systems look very good esp their air radiant system. THE question for us is what happens in Winter when we are away for a few weeks. We'd need to keep heat on? At what level? Would pipe size in the Legalett air radiant system (2" or 4") make a difference? Would it simply be better to go hydronic or electrical instead of the air radiant? Thanks.
