Underfloor Heating: Electric vs Hydronic Cost Comparison

underfloor heating cost

Today, warm floors in the dead of winter are no longer a luxury for the rich. The cost of underfloor heating has gone down so that it can be a practical option for bathrooms, kitchens, basements and even whole-house systems!

In this guide, we discuss how electric underfloor heating works, how it compares with hydronic systems, and explore the costs of both setups so you can compare quotes confidently.

Quick Summary

  • Electric underfloor heating (dry systems using mats, cables or thin film) is usually the cheapest to install for single rooms and retrofits and gives fast, on-demand warmth.
  • Hydronic underfloor heating (warm water through pipes) costs more upfront but is cheaper to run long-term when paired with an efficient boiler or heat pump.
  • 2025 costs: in the US expect roughly $10–$25 per sq ft installed for electric systems , while hydronic systems commonly range $7–$20+/ft² depending on scope.

How Electric Underfloor Heating Works

Electric underfloor heating, also called electric radiant floor heating, uses electric heating components that are laid beneath the floor covering. These components can be heating cables, preformed mats, or thin-film elements. 

They are designed to emit radiant heat upward through the floor finish (be it tile, stone, vinyl, or engineered wood). 

Electric underfloor heating is controlled by thermostats and can be zoned (meaning one thermostat per room). Because the systems are thin and use electricity, they are a popular choice for retrofits and rooms where installing pipes or a boiler connection would be disruptive.

Types of Electric Underfloor Heating

  • Loose cable systems — made of custom-laid loops for irregular rooms.
  • Prefabricated mats — these are mesh mats with fixed spacing for straightforward installation beneath tile or stone.
  • Thin-film/foil systems — these are low-profile sheets that are used for vinyl or laminate floors.

Each type has different installation methods and price points: mats are fastest to fit, while loose cable is most flexible for oddly shaped rooms or spaces.

Nuheat Electric Floor Heating Mat

The Nuheat Floor System can be installed for use under tile, stone, marble, laminate or engineered wood floors. These ⅛” thick mats are energy efficient, delivering up to 12 watts/sq. ft. or 41 BTUs/ sq. ft.

Each floor heating mat is also almost all DIY; an electrician is only needed to install a dedicated line, unless the room already has a dedicated line. Simply lay your thinset, roll out and press the Nuheat mat right onto the thinset, apply another layer of thinset and install your flooring.

Electric vs Hydronic Underfloor Heat

Upfront cost

Electric heating is typically less expensive for single rooms. Hydronic systems cost more to install due to the pipes, manifolds, pump, integration with boiler/heat pump that make up the system.

Running costs

Hydronic systems are generally cheaper to operate in the long run — especially when used with a heat pump. Conversely, electric heating tends to be more expensive monthly, particularly if used to heat large areas continuously.

Response time

Electric heats faster (due to low thermal mass), while hydronic is slower but offers steady room temperatures.

Best use case

Electric: 

  • Ideal for single rooms like bathrooms and kitchens
  • Use for spot heating
  • Good option for retrofits

Hydronic:

  • More practical for whole-house heating or large open-plan floors

Maintenance

Electric systems from reputable brands are generally low-maintenance. 

Hydronic systems require occasional pump/manifold checks and periodic servicing due to their more complex nature.

Underfloor Heating Costs

Electric underfloor heating: 

  • Material cost and installation ranges from $10–$25 per sq ft

Hydronic systems: 

  • $7–$20+ per sq ft for installed systems
  • Whole-house projects push the higher end because of extra plumbing, manifolds and source integration.

Note that prices vary with location, floor prep, floor finish, zoning, and installer rates. 

Retrofits in particular often require raising floor levels (to house the insulation + mats/screed), or embedding into thin screed systems, which push up labor costs. New builds on the other hand reduce prep cost.

Always get multiple local quotes to get the best possible pricing.

Floor Compatibility

Best

Ceramic, porcelain tile, and natural stone provide highest thermal conductivity, resulting in the fastest transfer of heat to the room.

Okay with care

Luxury vinyl plank (LVP) and engineered wood may be suitable, depending on the manufacturer’s temperature limits.

Challenging

Thick carpets or certain hardwoods may require lower W/ft² settings or be unsuitable. Always confirm compatibility with the floor and heater manufacturers.

Underfloor Heating FAQ

Can I use electric UFH as my main heating?

Technically yes, for small homes or very well-insulated buildings in temperate areas.

However, for whole-house heating in cold climates, electric systems are usually more expensive to run than hydronic systems powered by heat pumps or gas boilers. For whole-house settings, hydronic paired with a heat pump is often the most economical long-term choice.

Will underfloor heating damage my floors?

No, if installed correctly and the floor covering is compatible. Tile and stone floors have the fewest restrictions. For engineered wood and vinyl flooring, refer to the manufacturer’s temperature limits.

What other factors should I take into consideration when choosing?

  • Floor preparation needed (which can include removal, leveling, and insulation).
  • The terms of warranty for the heating elements and labor
  • Ask the contractor for an estimate of the running cost using your local electricity or gas prices.

Bottomline

Electric underfloor heating is cheaper and easier to install and maintain, but is limited to spot heating or single rooms. Hydronic heating costs more upfront, but is more cost-efficient in the long term. It’s also the better choice for heating larger areas.
