Radiant Floor Heating

Hydronic systems circulate heated water through flexible tubing installed beneath or within the floor. The water is typically heated by a boiler or another compatible heat source before returning through the system to be reheated.

Hydronic radiant heat may be suitable for:

• Whole-home heating
• New home construction
• Large additions
• Basements and concrete slabs
• Garages and workshops
• Multiple rooms or heating zones

Because hydronic systems require piping, controls, and a heat source, careful planning is necessary to achieve balanced and reliable performance.

Electric systems use heating cables or mats installed beneath the finished flooring. They are often used to provide supplemental warmth in individual rooms rather than heat an entire home.

Electric radiant heat may be practical for:

• Bathrooms
• Kitchens
• Entryways and mudrooms
• Small additions
• Rooms where extending hydronic piping is impractical

The best option depends on the project size, existing heating system, available utilities, flooring, and how frequently the space will require heat.

A properly designed radiant floor system can provide several advantages:

• Even room temperatures: Heat is distributed across the floor instead of entering through one or two vents.
• Warm floors: Radiant heating can make tile and other hard surfaces more comfortable during cold weather.
• Quiet operation: The system does not require a blower to circulate heated air.
• More design flexibility: Heating components are concealed beneath the floor, leaving walls free of radiators, baseboards, or additional vents.
• Less air movement: Radiant systems do not continuously circulate air and dust through ductwork.
• Individual temperature control: Separate zones may be created for different rooms or areas when the system is designed accordingly.

Radiant heat can be incorporated into new construction, additions, remodeling projects, and certain existing spaces. It is especially practical when flooring is already being removed or a new concrete slab is being installed.

Common applications include:

• Bathrooms and primary suites
• Kitchens and dining areas
• Finished basements
• Home additions
• New homes
• Garages and workshops
• Rooms with tile or other hard flooring

Retrofitting radiant heat beneath an existing floor may be possible, but access, floor height, insulation, and construction methods must be evaluated before the system is designed.

Tile, stone, and concrete conduct and retain heat effectively, making them common choices over radiant heating systems. Other materials—including certain engineered wood, laminate, luxury vinyl, and carpet products—may also be compatible when properly selected and installed.

The flooring manufacturer’s temperature limits and installation requirements must be considered. Excessive heat or improper installation can damage sensitive materials or reduce system performance.

Felger Hart Residential can coordinate the heating design with your builder, remodeler, or flooring installer to help ensure that the system and floor covering work together properly.

Radiant heating should be planned around the room’s heat requirements, insulation, floor construction, finished flooring, and available heat source. Hydronic systems must also account for tubing layout, water temperature, circulation, and zone controls.

Our team evaluates the project and develops a solution based on how the space will be constructed and used. Financing options are available, with approved credit, for qualified radiant heating installations.

A radiant system can develop problems with thermostats, controls, pumps, valves, wiring, heating elements, water circulation, or the heat source.

Contact Felger Hart Residential if you notice:

• A floor that no longer warms
• Cold areas within a heated room
• Uneven or inconsistent temperatures
• A thermostat that does not respond
• Unusual sounds from pumps or mechanical equipment
• Leaks or pressure changes in a hydronic system
• A system that takes much longer than usual to heat

Our technicians will evaluate the system and identify the source of the problem before recommending a repair.

Electric radiant systems generally have few accessible moving components, while hydronic systems include pumps, valves, controls, and heating equipment that require periodic inspection.

Routine maintenance of a hydronic system can help identify circulation problems, pressure concerns, leaks, or worn components before they interrupt heating. If the system uses a boiler, regular boiler service is also important.
