HYDRONIC RADIANT FLOOR HEATING COST HOW TO

Worthy of note: that requirement in code has nothing to do with whether or not a heating system has the ability to provide the entire heat load of a building, this is simply about comfort and making sure we don’t suffer any trauma from walking past a vent delivering air at a bone-chilling 16° Celsius. Because of that, every fully ducted ventilation system in a home with any type of radiant heat will require supplementary heating to heat ventilation air back up to ambient temperatures. According to code, ventilation air cannot be introduced into a building at a temperature below 17° Celsius at floor level, and not below 13° Celsius from vents located high on walls or the ceiling. In theory, yes, but it will not meet the requirements of the Canadian Building Code. Insulating air tubes near the heater box output to better distribute heat © EcohomeĬan radiant floor heating provide all the necessary heat for a home?

Systems can be used in conjunction with thermal-solar air heaters, which are less risky (and less expensive) than thermal-solar hydronic heaters.

A detailed cut list and directions are provided, making installation simple and quick.

Each system and zone layout is custom-designed to deliver heat evenly.

An air-heated tube system is not pressurized and there is no liquid to leak out, so an accidental screw put into an air tube is of no consequence.

When installing a hydronic tube system you need to be very cautious, since accidentally piercing a tube will render the system ineffective.

The reduced capacity air has to hold heat compared to water can reduce the risk of overheating.

With the system being entirely embedded in the floor, heat is also entirely contained in the floor, so there is no buildup of heat in the mechanical room as is common with hydronic systems.

The first 10-12% of each zone output is fully-insulated, the second 10-12% is half-insulated – this forces the hottest air further down the tubes to more evenly distribute heat throughout the floor.

Heater units use standard parts, so, long into the future when the warranty has expired, units can be easily removed and repaired by any electronics repair shop using commonly available parts.

A metal box frame is hard-wired and embedded in the concrete to house heater units, the heater units themselves plug directly into the box to allow for easy removal for maintenance.

Units are accessed through a small hatchdoor flush with the concrete and can be placed anywhere in the home – in the mechanical room, under appliances, or in a closet.

Legalett heating units are embedded in the floor along with the tubing, so they do not require a wall in the mechanical room to house boilers and manifolds.Advantages of air-heated radiant floors over hydronic:

This acts to remove moisture from the concrete and prevent corrosion of metal components in the heater box. There are no open vents, so there is no access point for rodents and insects.Īfter the concrete is poured, Legalett requires floors to be cured with an open-air construction heater (provided with the system) that maintains a temperature of 28☌ for 3 weeks before permanent heating units are installed. It is a closed-loop system where air is moved through either 2 or 4-inch PVC tubes (which are non-corrosive), so that no dust from the air in the home is introduced into the system. Legalett air-heated radiant floor heating systems are entirely embedded in concrete, including the heater box. Why the Legalett radiant floor system works: They are the only company we know of that provides this system if anyone knows of others, please let us know in the comments section at the bottom. Cure the concrete to remove moisture before systems are activated.Ī company called Legalett that originated decades ago in Sweden now manufactures and distributes heated-floor systems across North America (you can get a quote here).Make it a sealed, closed-loop system so that air in the heating system is not exchanged with the air of the house.If you really want to, you can read more about that here.

For Information about the importance of air quality in the home and how to improve it with ERV & HRV Ventilation systems see HERE.ĭuring inspections with remotely operated cameras, some even less appealing discoveries were made, including snakes, insects, dead rodents and their excrement. In the fall when systems were activated again, air circulating through dirty and moldy ductwork would distribute particulate and mold spores throughout the home. In summertime when systems were inactive, dust-filled ducts embedded in cool, humid concrete floors provided the ideal environment for mold to develop.
