What does dry construction underfloor heating cost?
The costs for dry construction underfloor heating average between €800 and €1,050 for 10 m², depending on whether you install the system as additional or main heating. The total price is determined by the surface area you want to heat and the type of heating system. Main heating requires more heating capacity and therefore slightly more material, which affects the costs per m².
Dry construction underfloor heating costs per surface area
| Surface area | Additional heating costs | Main heating costs |
|---|---|---|
| 5 m² | €400 - €450 | €600 - €650 |
| 10 m² | €800 - €900 | €900 - €1,000 |
| 20 m² | €1,200 - €1,400 | €1,800 - €2.000 |
| 30 m² | €1,800 - €2,100 | €2,700 - €3,000 |
| 40 m² | €2,400 - €2,800 | €3,600 - €4,000 |
| 60 m² | €3,600 - €4,200 | €6,300 - €7,000 |
| 100 m² | €7,800 - €9,100 | €9,900 - €11,000 |
The table shows that the price per m² decreases as the surface area increases. For an average living room of 30-40 m², you pay between €3,250 and €4,550, depending on the use. Main heating is approximately 35-50% more expensive than additional heating due to the extra heating capacity required.
Prices include 21% VAT and labour. Additional work such as installing a bypass costs €65 to €100. The professional carrying out the job calculates the exact price based on your specific situation and the chosen configuration.
Dry construction underfloor heating costs per type of heating
The costs for dry construction underfloor heating differ per type of heating. With additional heating, the system provides warm feet but does not fully heat the room – radiators are still needed for this. Main heating replaces radiators completely and heats the entire room. The cheapest scenario is additional heating for 5 m² starting from €400, while main heating for 100 m² costs between €9,900 and €11,000.
| Type of heating | Characteristics | Indicative price |
|---|---|---|
| Additional heating | Warm feet, radiators remain necessary | €400 - €9,100 (depending on surface area) |
| Main heating | Replaces radiators completely, heats entire room | €600 - €11,000 (depending on surface area) |
Price-determining factors for dry construction underfloor heating
The costs for dry construction underfloor heating are determined by several factors that each influence the total price. Some are practical, others depend on your specific situation. Below you can read what increases or decreases the price, and why.
Surface area
The number of square metres you want to heat is the most important price factor. The larger the surface area, the more material and labour are required. A room of 10 m² requires fewer pipes, heating elements, and insulation material than a room of 100 m². The costs per m² do decrease as the surface area grows, because fixed labour costs such as preparation and connection are spread over more square metres.
Additional or main heating
Main heating costs approximately 35-50% more than additional heating. With main heating, the system replaces radiators completely and must provide sufficient capacity to heat the entire room. This requires more heating elements per square metre and a more intensive installation. With additional heating, the system only provides warm feet and radiators remain the primary heat source, requiring less material and labour.
System material costs
The type of dry construction system determines a large part of the price. Systems with aluminium heat conduction plates are more expensive than standard insulation boards but conduct heat faster and more efficiently. Choosing a more expensive system increases material costs but can results in lower heating costs in the long run.
Installation height
The installation height of the system varies between 15 mm and 30 mm. A higher structure offers better insulation and heat distribution but costs more in material and takes up more room height. A thinner structure is cheaper but may heat less efficiently, meaning longer warm-up times.
Floor type
The finish floor you choose affects heat transfer. Tiles conduct heat best, causing the floor to warm up faster and heat more efficiently. Laminate or parquet insulate slightly more, extending the warm-up time. Flooring such as carpet slows down heat release the most. The type of finish requires no adjustment in the installation itself but determines how effectively the system works.
Subfloor condition
An uneven subfloor must first be levelled before the dry construction underfloor heating can be installed. Height differences of more than 5 mm per linear metre can lead to poorly functioning pipes and heat loss. Levelling costs extra material and labour time, increasing the total price.
Removing radiators
With main heating, existing radiators must be removed and pipes disconnected. This requires dismantling, disposal of material, and sometimes adjustments to the pipe structure. Removing radiators is an additional cost that does not occur with additional heating.
Installing a bypass
A bypass along the central heating boiler prevents the boiler from continuing to switch when the system has little demand for heat. This keeps the water moving and protects the boiler against wear. Installing a bypass costs €65 to €100 and is primarily necessary with main heating.
Underfloor heating distributor
The number of groups in the distributor determines how many zones can be controlled separately. More rooms mean more groups, increasing the costs of the distributor. A distributor with three groups is cheaper than a distributor with six groups but offers fewer control options.
Installation complexity
Installation in multiple rooms or connection to a heat pump requires more time and expertise. Systems running over multiple floors require extra piping, extending the labour duration. The more complex the job, the higher the total price.
Combination with heat pump
Dry construction underfloor heating works efficiently with heat pumps due to lower supply temperatures of 30-40°C. Installing a heat pump costs several hundred euros extra but lowers heating costs and increases energy efficiency.
Region
In large cities, costs are often higher than in rural areas. This is due to higher labour costs, travel time, and demand for professionals. Regional differences can be up to 10-15%.
Urgency and weekend
Urgent jobs are more expensive than planned work because the professional must adjust their schedule. Work in the weekend costs more than during the week due to weekend surcharges. Plan ahead to avoid these extra costs.
Extra costs and surcharges
Extra costs depend on your specific situation, such as urgent jobs or adjustments to the space. At Zoofy, you do not pay call-out charges.
- Urgent surcharge: Applies to urgent jobs because the professional must adjust their schedule
- Weekend surcharge: Applicable when work takes place during the weekend
- Installing a bypass: At the central heating boiler to prevent the boiler from cycling, costing €65 to €100
- Removing radiators: Necessary when switching to main heating and constitutes an additional price
- Levelling subfloor: Required when the existing floor is not flat
- Adjusting door frames and skirting boards: May be necessary due to the raised floor
- Heat pump installation: Costs several hundred euros extra
- Disposal costs: For rubble and old materials may be added
How does the professional work when installing dry construction underfloor heating?
The installation follows a fixed sequence where each step contributes to a well-functioning heating system.
- The professional assesses the existing subfloor and checks whether it is flat, dry, and clean. If necessary, the existing floor covering is removed and the subfloor is levelled.
- Special insulation boards with channels or grooves are laid on the subfloor. These boards contain preformed grooves into which the heating pipes fit.
- The heating pipes are laid in the grooves according to a predetermined pattern. In some dry construction systems, aluminium heat conduction fins are added for better heat distribution.
- All heating pipes are connected to the underfloor heating distributor, which controls the different zones.
- The system is filled, vented, and pressurised to check for leaks. A correct pressure test is essential for the quality guarantee.
- After approval, an underlay is applied on which the final floor covering is laid. A dry construction system has no drying time, so the installation for one room takes 1-2 days.
How can you save on dry construction underfloor heating?
There are several ways to save on the costs for dry construction underfloor heating without compromising on quality.
- Ensure good insulation: Install floor insulation before the dry construction underfloor heating is installed. This prevents heat from disappearing into the ground and lowers your energy bill.
- Prepare yourself: Move furniture and clear the workspace. This saves the professional labour hours and lowers the total price.
- Plan during the week: Do not book in the weekend or with urgency. Planned work during the week is more economical due to lower surcharges.
- Choose additional heating: If you only want warm feet in certain rooms, additional heating is cheaper than main heating.
- Combine with heat pump: Dry construction underfloor heating works efficiently with heat pumps due to lower supply temperatures, reducing your energy costs. The payback period is between 7-12 years.
- Book via Zoofy: You get a fixed rate in advance, with no call-out charges and no surprises. You only pay after completion of the job.
Common problems with dry construction underfloor heating
Problems with dry construction underfloor heating often relate to installation, dimensioning, or maintenance.
Cold spots
Cold spots occur due to incorrect dimensioning of the system or poor insulation under the floor. This causes uneven heat distribution, leaving certain zones colder than others. It affects comfort and increases energy costs through inefficient energy use.
Air in the system
Air in the system causes gurgling or clicking sounds and significantly reduces heat release. This occurs when the system is not correctly vented during installation or after maintenance. Periodic venting restores heat performance and prevents noise nuisance.
Leakage
Leakage is recognisable by damp spots or pressure loss in the system. This is caused by damaged pipes or poor connections and must be fixed immediately to prevent water damage.
