What does connecting a boiler cost?
Connecting a boiler costs an average of €1,200, including materials and labour. For a standard installation, costs range between €800 and €1,600. In more complex situations, such as laying new pipes or placing a large boiler in a difficult-to-reach space, costs can rise to €10,000. Simple connections, such as replacing an existing boiler without adjustments to the pipes, are possible from €350.
Overview of average boiler connection costs
Description | Price |
|---|---|
Average costs | €1,200 |
Typical range | €800 - €1,600 |
High costs | €10,000 |
Inexpensive | €350 |
The price for installing a boiler is determined by the labour time and the necessary material. A plumber charges an average of €60 to €75 per hour, and the installation usually takes 2 to 3 hours. Additionally, you must take into account the purchase price of the boiler itself, which varies from €400 to €2,600, depending on the type and capacity. When replacing an old boiler, the costs are often lower than with a completely new installation because the pipes are already present. All mentioned prices include 21% VAT and labour.
Costs of connecting a boiler per type
The costs for connecting a boiler vary greatly per boiler type. A standard tank boiler is the cheapest to purchase and install, while a solar boiler requires the highest investment but saves on energy costs in the long term. Below you can see what different boiler types cost, including device and installation.
Type | Device costs | Installation costs |
|---|---|---|
Standard tank storage | €400 - €1,600 | €150 - €600 |
Tankless | €250 - €2,500 | €400 - €1,500 |
Hybrid/high efficiency | €900 - €3,900 | €200 - €800 |
Solar energy | €1,000 - €6,000 | €2,000 - €4,000 |
Price-determining factors for connecting a boiler
The costs for connecting a boiler vary greatly per situation. Below you can read which factors determine the price.
Type of boiler
The type of boiler has a major influence on the costs. A standard tank boiler costs €400 to €1,600 and is relatively easy to install. A tankless boiler (instantaneous) costs €250 to €2,500 and requires more technical knowledge for the connection. A hybrid heat pump boiler costs €900 to €3,900 and often requires adjustments to the electrical system, which extends the installation time.
Energy source
Electric boilers cost between €200 and €2,900 and are easier to connect because they do not require a gas line. Gas boilers cost €250 to €1,800, but the installation is more complex due to the required gas connection and ventilation.
Ventilation system
Gas boilers need ventilation for the discharge of flue gases. A power vent increases the device price by €300 to €600, plus €300 to €500 for the required wiring. With direct venting to the outside, an opening in the wall sometimes needs to be made, which costs €500 to €1,000 extra.
Complexity of the installation
Labour costs vary from €150 to €800, depending on accessibility and the number of necessary adjustments. If the boiler is in a difficult-to-reach place, the installation takes more time.
Emergency versus planned
Emergency jobs cost more than planned work. If the professional has to adjust their schedule to visit you quickly, this entails extra costs.
Weekend
Work on the weekend is more expensive than during the week. Professionals charge a surcharge for work outside regular office hours.
Adjustments to piping
If new pipes are needed, costs rise significantly. Installing electrical wiring costs €550 to €2,200, installing a water pipe between €350 and €1,900, and adding a gas pipe €250 to €800.
Permits
For some installations, a permit is required. Permit costs vary from €150 to €1,950, depending on the type of work and the municipality.
Removal of old boiler
Removing and disposing of the old boiler costs €100 to €500. Large tank boilers cost more to remove than compact instantaneous heaters.
Region
In large cities such as Amsterdam, Rotterdam, and Utrecht, costs are often higher than in rural areas due to higher labour costs and travel time.
Accessibility and preparation
If the workplace is easily accessible and tidy, the professional works faster. Removing obstacles or clearing a tight space costs extra time, which increases labour costs.

Connection: The boiler is connected to the water, gas, and electrical lines.
Filling and bleeding: The system is filled with water and bled to remove air bubbles.

Explanation: You receive an explanation on the operation and maintenance tips.
How can you save on connecting a boiler?
There are several ways to reduce costs without compromising on quality.

Common signs that you need a new boiler
Rusty or discoloured water
If the water has a rusty brown colour, the anode in the boiler is likely defective. This leads to leaks and poor water quality.
Water does not get warm enough
A defective heating element prevents the water from reaching the desired temperature.
Loud banging or cracking
Unusual noises are usually caused by limescale deposits on the heating element.
Leaks
Visible leaks indicate serious internal damage and require immediate action.
High age
A standard tank boiler lasts 8 to 15 years. If your boiler is approaching this age, replacement is often more economical than repair.
