Floor Heater Technologies

Floor Heater

Floor heater technologies seem to growth rapidly since ancient time. Let’s look some of the technologies of the floor heater.

Contemporary under floor heater systems are commonly either warm water systems or electric systems. Systems can be poured into a stonework mix (called a poured floor system or a wet system) or fastened directly to the sub floor (called a sub floor system or dry system).

In a hot-water system floor heater, warm water is dispersed through pipes or tubes that are laid into the floor (usually a solid-screeded floor, although joist-based systems also work well). A variety of types of pipe are used as well as PEX, multi-layer (a composite of PEX, Aluminium and PEX) which is also known as Alupex (there is also a version using PERT instead of the PEX) and polybutylene (PB): copper pipes are rarely used.

Since it deals a good balance between cost and pressure drop, ⅝-inch (16 mm) diameter tubing is popular: ¾-inch (19 mm) and 1-inch (25 mm) tubing are somewhat exclusive, and ⅜-inch (10 mm) and ½-inch (13 mm) offer extra resistance, which means more energy spending to pump the liquid through the pipe; and the ⅝-inch tubing is often the minimum size needed for efficient thermo siphon.

In Europe, as well as the United Kingdom, 15 mm or 16 mm pipe is commonly used for floor heater system.

On the other hand, a floor heater system that designed to use solar-heated water that circulates by thermo siphon is prone to blockage by air bubbles. They are hard to pass up where the tubing lies so flat or may have high spots. Bubbles in the water build up in the smallest high spots, lastly blocking the flow. A small in-line centrifugal pump, 0.05 horsepower (37 W) in rating, can be used for purging. It will circulate water through the tubing fast enough to extricate an air bubble. The purge pump only activates when the system stagnates and the solar collectors near overheating. When circulation is restored, the pump shuts off.

Gas, oil, solid fuel, or electric-resistance hot-water boilers can be used as the source of heat for any floor heater system, as can a number of other technologies. Condensing boilers and ground-coupled heat pumps are principally well-suited as the operation of floor heater systems permit them to operate in their most efficient manner. Floor heater system can run as low a temperature as 35 °C (95 °F), allowing a heat pump to run at a coefficient of performance in excess of 4.0, compared to the 3.0 with the temperatures needed for use with wall radiators.

Wet floor heater systems can also be used in overturn, where cold water from a chiller is placed in the system taking heat energy out of the building. Nevertheless, care is needed to guarantee that surfaces' temperatures stay above the air's dew point temperature. Otherwise, slipping hazards or mold growth is a concern.
