Keep reading below for other amusing statements and claims.įloor heating systems deliver only about a Pipes aren't made of polyurethane nor are floor furnaces even close to underfloor radiant systems. there were so many unbelievable statements at this eHow article it's easier for us to advise readers to avoid any article that mentions 'polyurethane' pipes and 'floor furnaces' in the same breath. If air movement were a prerequisite for thermal comfort you would feel cold while sitting in the sun on a calm day.does that makes sense to you? Of course not. Air movement it is not a prerequisite for thermal comfort. Also you don’t need to move air for thermal comfort. When the blower is ‘on’ it is good – when it is ‘off’ it is less good – translation: if the indoor air quality system in your home is rendered useless by controlling thermal comfort it is IMHO dysfunctional. When designers use exclusively a furnace to move ventilation air, the ventilation air efficacy is a function of the on/off cycles of the blower. Such systems have the highest efficacy of all ventilation systems. So what radiant systems do is enable the use of balanced 100% dedicated outdoor air systems such as HRV/ERV’s. Just because you have radiant doesn’t make you exempt from building codes – you still need to ventilate…and that takes air. I’ve never understood these comments since ventilation is required regardless of what type of HVAC system you have. With radiant you’ll have stale air because nothing is moving the air around, or you need to have a furnace to move air around, or you need to move air to provide thermal comfort. Or forced air – neither of these is wet or dry Independent of the heating system be it radiant To measure the coincident condition is with bothĪll of this is to point out that the moisture is See why radiant heat in of itself cannot be described asĭry?
