Hydronic radiant / Discussions

How do you run ducts for heating and cooling with slab on grade construction?

...radiant heating systems. Cooling is a different matter, some people put in air-to-air heat pumps cooling, and radiant cooling is something of a contentious topic but can work, as long as you don't 'over' cool the floor to the point where you are creating condensation.  Heat pumps are a great idea as you mention, you ca...

What is the best heating / cooling system for a new build?

...hydronic radiant systems (water or glycol) that overheat, whereas electric wire heating systems shut off instantly. Also air heated radiant floors don’t overheat as much as liquid hydronic under floor heating due to the fact that air cools down much faster than water, so they tend not to overshoot the mark. Here you ca...

Is solar air heating for a floor as efficient as solar hydronic?

...radiant floor is most efficient. Thanks for your question, and I would start here in general terms of efficiency in heat delivery - there is no great difference in the energy efficiency between air heated floors or hydronic (liquid) radiant floors, at least when they are heated with the same fuel. Meaning – a boiler he...
