The total price of a boiler installation can vary greatly and is determined by several technical, functional, and structural factors. Below are the most important aspects that influence the amount of the investment.

1. Boiler type

The chosen boiler type is the biggest cost-determining factor.

2. Capacity (volume in liters)

The size of the boiler tank determines how much hot water is available, but also affects the cost of materials and installation.

The larger the content, the higher the material costs, the space required, and the heating time.

3. Insulation level and energy label

Boilers with high-quality insulation and an energy label of A or better consume less energy, but are often more expensive to purchase. The additional cost is recouped through lower electricity or gas bills.

4. Installation complexity

The placement itself significantly affects installation costs:

• Boiler location (e.g. basement, attic, shed)
• Accessibility of the room
• Presence of drains, air supply, fuse box
• New piping needed or not
• Flue for gas water heaters

Complex installations can cause extra costs of €500 to €1,500.

5. Additional components and options

6. Subsidy and Payback Period

For heat pump boilers and solar boilers, an ISDE subsidy will be available in 2025. This subsidy significantly reduces the net purchase costs:

7. Brand and Warranty Conditions

A-brands with longer warranty periods (5–10 years) and proven reliability are usually more expensive than lesser-known alternatives. These include:

• A-brands: Vaillant, Stiebel Eltron, Nefit Bosch, Inventum
• Mid-range: Tesy, Eldom, Ariston
• Entry-level: lesser-known import brands

Additional costs can range from €200 to €800 for A-quality and extended warranty.

The right choice and optimal use of a water heater can significantly contribute to lower energy costs and a longer system lifespan. The tips below will help you save maximally, both during purchase and use.

1. Choose the right content size

• A boiler that is too large consumes unnecessary energy to keep water at temperature.
• A boiler that is too small leads to loss of comfort or reheating.
• Have your content needs matched to your family composition and hot water usage.

Savings: €50 – €150 per year by avoiding overcapacity.

2. Insulate the water heater and pipes well

• Heat loss through the water heater tank or pipes increases energy consumption.
• Choose a model with good factory insulation (class A or higher).
• Also have central heating and hot water pipes insulated.

Savings: €30 – €80 per year, especially with electric water heaters.

3. Choose a water heater with energy label A or better

• Modern water heaters with efficient control and high-quality insulation are more economical.
• Pay attention to the European energy label when purchasing.
• Avoid older or second-hand models without a label.

Savings: €75 – €200 per year when replacing an old type.

4. Consider a heat pump water heater

• Consumes up to 70% less electricity than an electric water heater.
• Uses ambient air to heat the water.
• In many cases, ISDE subsidies are available.

Savings: €250 – €450 per year with average use (3 to 4 people).

5. Use a timer or smart control

• Heat water only when needed (e.g., at night or for peak times).
• Smart water heaters with built-in timers or apps ensure automatic switching.
• Avoid unnecessary heating during off-peak hours.

Savings: €40 – €100 per year, depending on usage patterns.

6. Apply for ISDE subsidy for sustainable solutions

• Heat pump water heaters and solar water heaters are eligible for subsidies from the RVO.
• The subsidy can amount to several hundred euros, depending on the capacity.
• The installer can often handle the application.

Savings: €500 – €1,200 once-off.

7. Choose a water heater with a shorter heating time

• Water heaters with a quick heating function consume less energy when used strategically.
• Ideal for households with staggered water usage (shower in the morning, bath in the evening).
• Pay attention to the heating time in the product specifications.

Savings: €25 – €75 per year with smarter use.

8. Place the water heater as close as possible to the taps

• The shorter the pipe, the less heat loss and water loss.
• Limit waiting time and avoid wasting cold water.
• During renovation: consider decentralized water heaters for the kitchen or bathroom.

Savings: €20 – €50 per year and water savings.

9. Maintenance annually for gas or solar boilers

• Dirt accumulation or limescale increases energy consumption.
• Have the boiler checked annually (for gas models: CO safety).
• Descaling extends the lifespan with hard water.

Savings: €50 – €100 per year in efficiency loss.

10. Combine with solar panels (if electric)

• Electric boilers can run cost-effectively on your own solar power.
• Combine with smart controls that heat during peak production.
• Especially effective for daytime use (home workers, families).

Savings: up to €0.35 per kWh less electricity purchase costs (2025).

When you have a boiler installed or replaced, there are a number of practical, technical, and legal aspects to consider. These notes help in correctly assessing costs, execution, energy consumption, and regulations.

1. Boiler is not a heating boiler

• A boiler only provides hot tap water (shower, kitchen, bath), and therefore not central heating.
• If you also want to heat your house, you need a central heating boiler, heat pump, or a combination system.
• With heat pump boilers and solar boilers, a combination with a buffer for central heating may sometimes be possible, but this requires additional technology.

2. Capacity should match hot water usage

• A boiler that is too small leads to a shortage of hot water, especially when bathing or multiple showers.
• A boiler that is too large unnecessarily increases energy consumption.
• Have the required volume matched to the number of people in the house and the usage pattern (e.g. bath, rain shower, simultaneous use).

3. Placement space and ventilation are essential

• The boiler must have sufficient space for safe installation and maintenance.
• Ventilation or air supply is required for heat pump boilers (preferably ≥ 20 m³/h).
• Solar boilers require free roof space for the placement of collectors and good orientation (preferably south-facing).

4. Boiler consumes energy, even when idle

• Hot water is kept at temperature, even if you don't use it.
• Models with good insulation and smart control limit this loss (standby loss).
• In case of absence (e.g. vacation) it is advisable to switch off the boiler temporarily or set it to 'vacation mode' if available.

5. Boilers require maintenance and can calcify

• Especially with hard water (>8 dH), boilers can calcify quickly, which reduces efficiency.
• Periodic maintenance and descaling significantly extend the lifespan.
• Gas boilers and solar boilers require legally required safety checks.

6. Electric boilers are relatively expensive to use

• They have no combustion emissions, but they do use a relatively large amount of electricity.
• They are especially suitable for small households or places without a gas connection.
• With high hot water demand, a heat pump boiler or solar boiler is often cheaper in the long term.

7. Connections and drainage may require extra work

• In older homes, there are often no separate groups in the meter cupboard or suitable drainage points available.
• With solar boilers, pipework and roof penetrations are required.
• Take into account any demolition work, adjustment of electricity or expansion of the meter cupboard.

8. ISDE subsidy is only possible with recognized installation

• Heat pump boilers and solar water heaters are only eligible for subsidy if they:
• Are on the approved equipment list of RVO
• Have been installed by a recognized installer
• Are correctly registered after installation

9. Permits usually not required, unless roof modifications

• No permits are required for standard electric or gas boilers.
• For solar water heaters, municipal regulations may apply to roof collectors (monument, protected cityscape).
• If in doubt, check with your municipality or installer.

10. Combine replacement with sustainability or renovation

• When you are already working on a renovation or sustainability project (e.g. insulation or heating replacement), this is the right time to also address your boiler.
• You save on labor, avoid duplicate work and can better coordinate systems with each other.
