Speedheat Underfloor Heating

How does underfloor heating compare with air convection type heating?

With convection heating, air is being heated which subsequently rises to the ceiling whilst cold air gets sucked to the bottom of the heater. An oil-filled fin heater or reverse cycle air conditioner are typical convection heaters. The heat transfer from such heaters is 85% by convection (air flow) and about 15% is by thermal radiation. This air circulation causes drying of the skin as well as evaporative cooling.

Floor heating provides a much more comfortable environment as the heat is radiated evenly from the floor, leaving no cold spots, improving your comfort levels.

Heat generated from electric floor heating is radiant heat (like the warmth of the sun).  Radiant heat does not warm the air directly, but it warms all solid objects, including obviously, the occupants. There is minimal convection, giving you that tip-toe comfort.  The diagram above compares the differences in comfort levels experienced.

Compared to air convection heaters, floor heating offers the following benefits:

Improvement in comfort levels.
Better indoor air quality - minimal drying effect or circulation of dust and allergens.
Heats the area evenly compared to a conventional free standing heater.
No hazard for physical injuries due to accidental contact leading to tripping and falling.  This is why floor heating is so popular in hospitals and health care institutions.
No maintenance.
Occupies no wall space.
Heaters are very quiet.

How does electric underfloor heating compare with hydronic underfloor heating?

Hydronic systems use water as the heat transfer fluid that is circulated through a network of pipes between the floor and the boiler. 
The concrete slab acts as a thermal mass to retain heat, so that you have a large hot block underneath your floor.  Because of this thermal mass, systems take long to heat up.

Take a look at our comparison table:
Speedheat vs hydronic underfloor heating

Hydronic underfloor heating is better suited for the European climate with long cold winters.  The high thermal mass does not allow the heating system to respond quickly to changing weather conditions.
