Hydronic Floor Warming Systems

This is why it is called radiant floor heating.

Hydronic floor warming systems.

The heat output from most hydronic emitters be they baseboard radiant floor circuits or air handlers doesn t vary in proportion to the flow rate passing through them. It works by running warm water through durable pex tubing that is installed in the floor and is heated by a boiler water heater or geothermal. As a bonus the film of this radiant floor heating mat only uses 12 watts to raise the floor temperature to comfortable levels. The graph in fig.

Hydronic radiating floor heaters these radiant floor systems use water or a special compound created by mixing water and an antifreeze solution like propylene glycol. The system is using heat from the heated fluid that is running through the pipes which are installed under the floor. Hydronic floor heating systems are designed to heat your home efficiently. Hydronic systems hydronic liquid based radiant heating systems use little electricity which is a benefit for homes in areas with high electricity prices or are off the power grid.

How hydronic radiant floor heating works hydronic radiant heating system a hydronic system uses a heat source a pump and pex tubing. Hydronic radiant floor heating uses hot water to warm your home and is the most efficient of the three systems. In all you can expect to pay anywhere from 6 000 to 14 000 to install a hydronic radiant floor heating system. Typically 10 of design flow rate yields about 50 of design heat output.

The heat transfer fluid runs in a closed circuit between the boiler and the floor. The system delivers heat directly to the floor and then radiates to surrounding objects. The first radiant floor heating systems were hydronic systems which featured heated liquid that circulated under the surface of the floor. While it was done as a new house was being built in my last house i poured a concrete floor on top of a wood framed floor system and could have put radiant heat in that as well.

Hydronic heating was first used by ancient chinese populations as well as the ancient romans but naturally there have been significant developments in the technology since those early days. Hydronic heating systems use different types of pipes specially designed for this purpose. The system works via pex pipe a small pump a water heater and a thermostat. This includes the system itself and the cost for a dedicated water heater or boiler generally 360 to 1 000 for a 50 gallon water heater or approximately 6 000 for a boiler.

Because there can be no joints in the pex tubing in the floor uncut lengths of tubing snake through the floor starting and ending at a manifold. And the floor heating system is installed it s as simple as that. This is about installing hydronic radiant floor heating in a slab floor system. It consists of a boiler or hot water heater which warms the water.
