What are the expected costs for electric underfloor heating?

Electric underfloor heating consists of thin heating mats or cables that heat the floor via electricity. The system is often used as supplementary heating in smaller rooms.

1. Purchase and installation costs

The installation costs depend on the surface area and the situation (renovation or new construction).

Average prices:

Important:

• For larger areas, the price per m² decreases slightly due to economies of scale.
• Often, electric underfloor heating can be installed on an existing floor without chiseling or breaking.

2. Running Costs

Calculation example when used as supplementary heating (bathroom):

• Power: 150 W/m²
• 10 m² = 1,500 W (1.5 kW)
• Usage: 2 hours per day
• Consumption: 3 kWh per day
• Electricity price: € 0.30 per kWh
• Daily cost: € 0.90
• Annual cost: approx. € 330.

As additional heating:

• Continuous use can amount to € 35 – € 50 per m² per year, depending on insulation and usage.

3. Maintenance costs

• No periodic maintenance required.
• In case of malfunctions, the floor must be opened locally; this rarely occurs.

4. Total costs (example 10 years)

For a bathroom of 10 m² (additional heating):

• Installation: € 800
• Consumption 10 years: 10 × € 330 = € 3,300
• Total (10 years): ± € 4,100

When is electric underfloor heating interesting?

• For bathrooms, toilets or small spaces (additional heating).
• During renovations without major structural changes.
• As a comfort solution alongside another heating system.

Many homeowners who request quotes via jeofferte.nl consciously choose electric underfloor heating only in specific rooms to keep costs and electricity consumption limited.

Conclusion

• Installation costs: € 30 – € 60 per m²
• Running costs: highly dependent on usage and tariff
• Best suited as additional heating, less so as primary heating due to the higher energy price.

The total costs of underfloor heating consist of installation costs and running costs.
These are determined by a number of technical and practical factors.

1. Type of underfloor heating system

• Water-based systems
• More expensive to install (pipes, manifold, pump).
• Lower running costs in the long term.
• Suitable as the main heating system.
• Electric systems
• Cheaper to purchase and install.
• Higher running costs (electricity).
• Especially suitable for supplementary heating.
• Infrared underfloor heating
• Thin film, little demolition work.
• Slightly more expensive to purchase per m², depending on the room.

2. Size of the heated surface

• Economies of scale: the larger the number of m², the lower the price per m².
• Small spaces (bathroom, toilet) have relatively high costs per m².

3. New construction or renovation

• New construction: easy to integrate, lower costs.
• Renovation: extra work (breaking open floor, leveling) makes installation more expensive.

4. Insulation and floor preparation

• Good insulation: prevents heat loss and allows for lower power.
• Poor insulation: can cause extra costs for insulation material or more heating capacity.

5. Type of floor covering

• Tiles and natural stone: optimal conductivity, no additional measures required.
• PVC and poured floors: very suitable.
• Wood and carpet: special measures required, this may increase costs.

6. Choice: main or supplementary heating

• Main heating: higher capacity and more groups, therefore more expensive to install.
• Supplementary heating: cheaper, limited to small areas.

7. Control and home automation

• Simple thermostat: lower costs.
• Smart zone control and home automation: higher investment, but more efficient use and energy savings.

8. Energy source and consumption

• Electricity and gas prices directly affect operating costs.
• Low-temperature sources (such as heat pumps) significantly reduce operating costs.

9. Installer and installation quality

• Craftsmanship: a well-designed system performs more efficiently.
• Compare quotes: via platforms such as jeofferte.nl you can make price and quality differences clear.

Conclusion

The costs of underfloor heating are determined by the type of system, the size of the room, the condition of the house, and the chosen finish and control system.
A good preliminary calculation prevents surprises later on and helps to find the right balance between investment and comfort.

Electric underfloor heating uses electricity to generate heat.
The costs are therefore dependent on:

1. The power of the system (in Watt per m²).
2. The number of hours the system is on.
3. The price of electricity (dynamic tariff or fixed contract).
4. The insulation and heat demand of the room.

Power and consumption

• Average power electric underfloor heating: 100 – 160 W/m².
• In a well-insulated bathroom of 10 m², this means a power of about 1 – 1.6 kW.

Calculation example:

• 10 m² bathroom, 150 W/m²
  = 1,500 W (1.5 kW)
• 2 hours per day on
  = 3 kWh per day
• Electricity price 2025: € 0.30 per kWh
  = 3 × € 0.30 = € 0.90 per day (approximately € 330 per year with daily use).

With main heating in a larger room, this amount can be much higher.

Consumption costs per m²

For average use (auxiliary heating):

• Annually: approx. € 10 – € 20 per m² per year
  For main heating (constant heating):
• Annually: approx. € 35 – € 50 per m² per year (depending on insulation and use).

When are the costs higher?

• Poorly insulated homes: more heat loss.
• Continuous use in large spaces.
• High electricity rates (without dynamic or night rates).

Limit costs

• Use programmable thermostats or home automation.
• Combine electric underfloor heating only in small spaces with another system.
• Pay attention to the power per m² when purchasing: in many cases 100 W/m² is sufficient.

Many homeowners who request quotes via jeofferte.nl therefore choose to use electric underfloor heating only as additional heating in the bathroom or toilet.

Conclusion

Electric underfloor heating is easy to install and ideal for comfort, but the consumption costs are higher than with water-based systems.
As additional heating, consumption remains limited and affordable; as main heating in large rooms, energy consumption can increase considerably.
