Hydronic radiant floors – The most popular and cost-effective type of radiant heating, hydronic radiant floor systems pump water heated from a boiler through tubing laid in a pattern under the floor. Manifold setup allows varied heating of different zones. This is ideal for homes that already use a water heater.

There is less dust circulating around the house than with forced-air systems. There are no surfaces that become too hot and burn dust as with electric baseboard systems.

High-performance green homes that need little heating energy would not benefit or would benefit very little from the added costs of putting in an expensive heating system. Other, less-expensive heating options can provide the same level of comfort, particularly when the building envelope already does a fine job.

Circulating pumps are centrifugal pumps designed to generate a forced circulation in a closed system. Examples are heating systems for hot water (see Circulator pump) or high-temperature hot water at temperatures above 120 °C (see Hot water pump), heat transfer systems (see Heat transfer pump), forced circulation boilers (see Fig. 3 Circulating pump) and reactor circuits (see Reactor pump). They are also used in open systems (e.g. swimming pool filtering systems). See Fig. 1 Circulating pump

Circulating pumps are centrifugal pumps designed to generate a forced circulation in a closed system. Examples are heating systems for hot water (see Circulator pump) or high-temperature hot water at temperatures above 120 °C (see Hot water pump), heat transfer systems (see Heat transfer pump), forced circulation boilers (see Fig. 3 Circulating pump) and reactor circuits (see Reactor pump). They are also used in open systems (e.g. swimming pool filtering systems). See Fig. 1 Circulating pumpThe design of a circulating pump is often determined by the frequently high temperature of the fluid handled and the relatively low head (in relation to the system pressure), which corresponds to the head loss (see Pressure loss) in the circulation system. Different types of circulating pumps are used in closed pump circuits: circulating pumps with or without a shaft seal, and special designs.Circulating pump with shaft sealCirculating pumps with a shaft seal are often horizontal pumps, driven by electric motors (see Drive) or steam turbines. Their pump shafts are sealed against the full pressure of the closed system by cooled gland packings or mechanical seals. The thrust bearing (see Rolling element bearing) has to be particularly robust to absorb the high static axial thrust.See Fig. 2 Circulating pumpThis type of pump is usually an economical solution for system pressures of up to 100 bar. For higher system pressures circulating pumps without shaft seal are used.Circulating pump without shaft seal Seal-less circulating pumps are also referred to as glandless circulating pumps. They are often vertical pumps, driven by wet rotor motors with or without a can (see Canned motor pump). See Fig. 3 Circulating pumpThe pump and the electric motor are contained in a common, pressure-tight casing with a heat barrier between the pump section and the motor section. The heat barrier, which can either be an active or a passive component, enables the pump set to handle fluids with temperatures of up to 420 °C.The bearings (see Plain bearing) are lubricated by the fluid handled. The system pressure is virtually unlimited. The completely leak-free design makes these pumps suitable for handling hazardous or valuable fluids.Special designs of circulating pumpsCirculating pumps can also be specially designed for specific applications:With special impellers for liquid/gas mixtures or suspensionsWith sealing systems incorporating a gas cushion or meeting other special requirements of nuclear reactor technologyWith heating devices for liquids which solidify rapidlyWith protective lining preventing erosionExplosion-proof designs (see Explosion protection)

Consistent heat may not be desirable for homeowners who like to turn their heat on and off at different times of the day.

Radiant floor heating costs more to install than other types of heating, particularly for retrofits. Also, depending on your local climate, you may still need a separate air-conditioning system. You can expect to pay 50% more for installing a hydronic radiant floor heating system than for a conventional forced-air system. Costs have averaged $12-15 per square foot in projects we have managed.

While it does cost more, radiant floor heating is a popular option. It provides so much more comfort than what many of us have experience with in older, drafty, or ineffectively heated homes. A well-operated radiant heating system with a programmable thermostat can save you hundreds of dollars on home heating bills. Also, many states have financial incentives for upgrading homes to boost energy efficiency. If you’re building a small home, this is something to consider.

There is a time lag of heat movement through the flooring. This can lead to an overheating problem if there are other sources, such as passive solar, already delivering heat to a space. It is probably best to disable or avoid installing radiant floor slabs where solar heat will already heat the air more directly.

Air-heated radiant floors – Air cannot hold a large amount of heat, so this type of system is rarely installed. They are not cost-effective for residential use.

To be effective, floor coverings must be thin and conductive. The covering should not insulate the heating system from the room. Ceramic tile is the most common and effective floor covering for radiant floor heating, but thin carpeting and wood can also be used.

For hydronic heating, a lower boiler temperature than one would need for baseboard heating increases boiler life and gives the option to use hot water heated by solar energy. This is difficult to permit, though, and it is often a DIY project.

Radiant floor heating turns your floor into a large-area radiator. The floor becomes a heated surface that directly warms the home. This floor can be “charged” during off-peak hours, when electricity is cheaper, and, if the thermal mass is large enough, it can keep a home comfortable all day without further electrical input. Other options to heat a home include forced-air heating, baseboard heating, gas burners, electric heating elements, space heaters, and passive solar design.

This type of heating is good for when building occupants have acute chemical sensitivity or allergies. A forced-air system could distribute dust, and an electric heating element or gas burner can burn dust particles.

While great for smaller rooms with lower roofs, in some cases it can be less energy efficient than forced-air heating. Check with a heating contractor to see if it would be sensible.

Radiant floor heating is very quiet. There is no airflow through ducts as one would hear from forced-air heating systems, and there is no gurgling and little to no expansion and contraction creaking as one would hear from baseboard radiators.

Circulating pumps with a shaft seal are often horizontal pumps, driven by electric motors (see Drive) or steam turbines. Their pump shafts are sealed against the full pressure of the closed system by cooled gland packings or mechanical seals. The thrust bearing (see Rolling element bearing) has to be particularly robust to absorb the high static axial thrust.

With a forced-air system, heated air rises up to the ceiling, then cools and sinks back down. A radiant floor system gives a more desirable temperature gradient throughout a room.

This type of pump is usually an economical solution for system pressures of up to 100 bar. For higher system pressures circulating pumps without shaft seal are used.

At New Avenue, we’ve incorporated radiant floor heating in many of our projects. Here’s a short list of advantages and disadvantages of radiant floor heating:

Electric radiant floors – This type of heating uses electric cables or electrically conductive plastic mats installed beneath the floor covering. It is cost-effective when used with flooring of significant thermal mass. Electric systems are cheaper to install than hydronic systems, but In the long run it would likely be less expensive to use a different fuel source and go with a hydronic system, which is powered by gas. This option is frequently used to retrofit a single room or to add a little luxury. This is common in bathrooms but can be ideal for a smaller home or for occasional use.
