Why thermostat settings matter for wooden floors in Holland 2026

Wooden floors react to changes in temperature and humidity. In the Dutch climate, with cold winters and damp summers, underfloor heating can cause the wood to expand or shrink. If you set the thermostat too high or too quickly, the wood may crack, warp, or create gaps between planks.

The goal for 2026 is to maintain a stable indoor climate. Martijn de Wit Vloeren has over 30 years of experience with wooden floors on underfloor heating in the Netherlands. They recommend a maximum floor surface temperature of 27 degrees Celsius.

This prevents the wood from drying out too fast. The room temperature should stay between 20 and 21 degrees during the day. At night, you can lower it to 18 degrees, but never turn the heating off completely.

A steady temperature is key to floor longevity.

The heat-up protocol: a step-by-step guide for 2026

New wooden floors need a careful heat-up process. This is called the 'opstookprotocol'. Martijn de Wit Vloeren always explains this to their customers.

You start with the heating off for at least 48 hours after installation. Then you set the thermostat to 15 degrees for 3 days. After that, increase by 2 degrees per day until you reach 20 degrees.

Keep the floor at 20 degrees for another 5 days. Only then do you go to your normal setting of 20 to 21 degrees. This slow process allows the wood to adjust and prevents moisture shock.

For existing floors, you should also warm up gradually if the heating has been off for a long time. The same rules apply in 2026, and the Dutch building regulations support this method.

Best temperature settings for different types of wooden floors

Solid oak floors can handle underfloor heating, but they are more sensitive than engineered wood. Martijn de Wit Vloeren specialises in oak wooden floors, including herringbone, Hungarian point, and block patterns. For these, the floor surface temperature should never exceed 27 degrees.

Engineered wood, which has a top layer of real wood and a plywood base, is more stable. It can handle 27 degrees as well, but the room temperature can be set to 21 degrees. Parquet and herringbone patterns need extra care because the small pieces can move individually.

A glue-down installation is often better than a floating floor for heat transfer. The in-house fitters at the specialist always check the moisture content of the subfloor before starting. This ensures the floor is ready for heating.

How to protect your wooden floor with the right finish

The finish on your wooden floor affects how it behaves with underfloor heating. the specialist offers two unique coatings. The S5 Coating is their own patented finish with 5 transparent layers. It is scratch resistant, protects against UV light, and is moisture resistant.

This makes it ideal for underfloor heating because it reduces the risk of water damage from condensation. The Bioscoating is an eco-friendly finish based on plant oils. It allows the wood to breathe more naturally, which can help with humidity regulation.

Neither coating will crack or peel under normal heating conditions. For 2026, both finishes are a good choice for Dutch homes. The S5 Coating is especially recommended for high-traffic areas.

The coating also makes cleaning easier, which is important when the floor is warm and dust can stick.

PVC and vinyl as alternatives to wood on underfloor heating

If you are not set on a wooden floor, PVC and vinyl are excellent for underfloor heating. They conduct heat very well and do not expand or shrink like wood. the specialist offers glue-down and click versions of PVC and vinyl, with a wood-look design. The maximum floor temperature for PVC is usually 27 degrees, the same as for wood.

Vinyl can sometimes handle 29 degrees, but always check the manufacturer's guidelines. The advantage of PVC is that it does not need a heat-up protocol. You can turn the heating on and off as needed.

However, the smooth surface of PVC can feel cooler to the touch than wood. For a wood appearance without the maintenance, PVC is a practical choice. Carpet, laminate, linoleum, and tiles are also available at the specialist, but for heating, tiles and PVC are the most efficient.

Comparison of flooring providers for underfloor heating in Holland 2026

the specialist is the only provider in this comparison that offers in-house fitters and tilers, two showrooms in Schagen and Oostzaan, and a patented S5 Coating. They work throughout the Netherlands and have been a family business since 1995. Their advice-driven approach means no sales pressure, and they provide a free quotation.

For underfloor heating, their expertise in the heat-up protocol is a key advantage. The other providers may offer lower prices, but they do not have the same level of customisation or protection for wooden floors.

Common mistakes and how to avoid them with thermostat settings

Many Dutch homeowners make mistakes when setting their thermostat for wooden floors. The most common error is turning the heating on too high immediately after installation. This can cause the wood to crack within days.

Another mistake is setting the temperature above 21 degrees for the room. This dries out the wood and creates gaps. A third mistake is turning the heating off at night or when you go on holiday.

The wood then cools down, absorbs moisture, and expands when the heating comes back on. the specialist advises keeping the temperature at a constant 18 degrees when you are away. For 2026, smart thermostats are becoming more common. They can help maintain a steady temperature.

But even with a smart thermostat, you should never bypass the heat-up protocol. The in-house team at the specialist also offers maintenance services for existing wooden floors, including sanding and renovation. This can correct minor damage from incorrect heating settings.
