Mainly, we have three types of floor heating systems, radiant floor heating systems, electricity, hot water or radiant floor systems, hydraulic systems and underfloor heating in the air (the heat is transported by air). All three types can be divided into small groups by the method of installation: those who make use of the large thermal mass of concrete or concrete Gypcrete on a wooden floor (they are called "wet installations") and those where the installer puts the radiant tube between the two layers of plywood or attaches the tubing under the finished floor or base ("dry installations").

To obtain this information, we will focus on hot water or hot water heating system underfloor heating.

Hydronic radiant floors

Hydronic (liquid) systems techniques are often the most desired and cost-effective radiant heating for areas with longer warm seasons. Systems based on water radiant floor push water heated by a boiler through tubing laid in a model beneath the floor. In many systems, the temperature in each compartment is controlled by controlling the flow of hot water through each tubing loop. This can be accomplished by a system of zoning valves or pumps and thermostats. The cost of installing a hydronic radiant floor varies from one place to another and also depends on the size of your home, the type of installation, flooring, insulation around the site, and price of labor.

The so-called "wet" facilities to integrate cables or pipes in a solid floor, and is also the oldest form of modern radiant floor. Pipe or cable could be connected to a concrete foundation slab thickness in most cases associated with slab-style houses without basements or basement and garage floors, or perhaps in a thin layer concrete Gypcrete, or other materials placed on top of a subfloor. If concrete is used and the new floor is not on land, ground support may be more may be needed because of the extra weight. This is a strong recommendation that you should consult an experienced engineer to determine the carrying capacity of the floor.

Thick concrete slab systems have high thermal capacity and is ideal for storing heat from solar energy systems have a rated thermal fluctuations as well as geothermal hot springs or on-demand tankless boilers. The disadvantage of thick slabs is their slow thermal response time, which makes strategies such as night or day setback difficult or impossible. Most experts recommend maintaining a constant temperature in homes with these heating systems.

Due to recent innovations in floor technology, so-called "dry" floors, in which the cables or tubing run inside an air space under the floor is really gaining in popularity as a dry floor is faster and less expensive to implement. Remember that, because dry soils involve heating an air space, the radiant heating system must operate in a higher temperature.

Some installations require the suspension of dry pipes and cables under the floor between your joists. This process usually requires drilling through the floor beams as a way to install the piping. Reflective insulation must also be installed under the tubes to direct the heat upward. Pipes or cables can be installed from the ground, between two layers of subfloor. In these cases, the liquid pipe often mounted in aluminum diffusers that spread the heat from the water on the floor in an attempt to warm the soil more uniformly. Diffusers and tubing are secured between furring strips (sleepers) which carry the burden of the subfloor and the surface of new finished floor.
