Heating boilers come in several variations. The right choice depends on consumption, hot water needs, the house size, the insulation level and any wishes for sustainability or hybrid use. Below is an overview of the four main types of boilers with explanation.

1. HR boiler (High Efficiency)

The HR boiler is the standard in the Netherlands. This gas-fired boiler uses condensation technology to achieve high efficiency (up to 107%).

• Heats: central heating and tap water (combi boiler)
• Fuel: natural gas
• Application: almost all types of houses
• Advantage: affordable, compact, reliable
• Disadvantage: runs on natural gas, no power generation
• Price incl. installation: €1.800 – €3.800

2. HRe boiler (High Efficiency Electricity)

The HRe boiler is an advanced HR boiler that also generates electricity via a micro-CHP (e.g. with Stirling engine or fuel cell).

• Heats: central heating and tap water
• Fuel: natural gas
• Yield: also electricity (approx. 1,000–1,500 kWh/year)
• Advantage: lower electricity bill, efficient with high gas consumption
• Disadvantage: high purchase price, niche product
• Price incl. installation: €4,500 – €6,800

3. Hybrid boiler (HR + heat pump)

A hybrid boiler combines an HR boiler with a small air/water heat pump. The heat pump provides most of the heating; the boiler kicks in when it's cold or for hot water.

• Heats: central heating via heat pump and/or boiler, tap water via boiler
• Fuel: natural gas and electricity
• Advantage: up to 60% less gas consumption, ISDE subsidy possible
• Disadvantage: higher investment, extra outdoor unit required

4. All-electric heat pump (gas-free)

An all-electric heat pump is a fully electric solution without gas. The pump extracts heat from the outside air or ground and uses it to heat the home and tap water. Requires good insulation.

• Heats: central heating and tap water, fully electric
• Fuel: electricity
• Advantage: no more natural gas needed, future-proof
• Disadvantage: high purchase costs, structural adjustments needed
• Price incl. installation: €8,000 – €14,000
• Subsidy (2025): €2,400 – €3,000

An HRe boiler is an HR combi boiler that also generates electricity. This is done via an integrated micro-cogeneration (micro-CHP). The electricity that is generated, is used directly in the home, which leads to a reduction in the electricity consumption from the grid.

The HRe boiler is especially interesting for homes with a high and constant heat consumption. Think of larger households, corner houses or detached houses.

Technical characteristics

• Fuel: natural gas
• Generation: heating, hot tap water and electricity
• Technique: micro-CHP (cogeneration via Stirling engine or fuel cell)
• Heat efficiency: up to 107%
• Electricity generation: approx. 1,000 – 1,500 kWh/year
• Lifespan: 10 – 15 years
• Subsidy: occasionally via innovation or pilot schemes, not standard via ISDE

Advantages of the mCHP boiler

• Offers combination of heating and electricity generation
• Reduction of power consumption through self-generation
• Well suited for homes with daily and continuous heat demand
• Works autonomously: electricity is generated when there is a heat demand, without sun or wind needed
• Functions as HR boiler in case of power failure

Disadvantages of the mCHP boiler

• High purchase costs compared to standard HR boilers
• Not profitable with low gas consumption or well insulated homes
• Technically more complex, with higher maintenance costs
• Less suitable for a future in which gas is completely phased out
• Limited range of models and manufacturers

Prices HRe boilers (2025)

Prices include installation, disposal of old boiler, adjustment and flue gas extraction. Excluding maintenance contract.

Electricity yield and savings

Please note: electricity generation depends on the number of operating hours (heat demand). The system is largely inactive in the summer.

Maintenance and service costs

The HRe boiler requires specialist maintenance due to the micro-CHP module.

Known Models (2025)

There is a limited supply on the Dutch market. Many suppliers are switching to hybrid or all-electric solutions.

Who is the HRe boiler suitable for?

• Homeowners with high gas consumption (e.g. ≥ 1,500 m³ per year)
• Buildings with constant heat demand, such as care homes, multi-family homes or large households
• Situations where generating electricity yourself is desired without space for solar panels
• Project-based applications (pilot projects or sustainability with retention of gas infrastructure)

Not suitable for small or well-insulated homes, or households that want to become fully sustainable in the short term via heat pump technology.

The CW value (Comfort Hot Water) indicates how much hot water an appliance can deliver per minute and which application this comfort level is suitable for. CW classes are standardized by Stichting Gaskeur and range from CW1 (low comfort) to CW6 (very high comfort).

CW values are particularly relevant when purchasing a high-efficiency combi boiler, hybrid boiler, or heat pump with a boiler.

Why is the CW value important?

• Determines if you have enough hot water for a shower, bath, and multiple taps
• Prevents comfort complaints (such as pressure loss or cold water)
• Is crucial when choosing the capacity and type of boiler
• Influences the price of the installation

CW Classes Explained

The liters per minute stated apply at a temperature of 40°C mixed water (from a unit that heats cold water).

How to choose the right CW value?

CW3:

• One shower, no bath
• Limited hot water use
• Apartment or studio

CW4:

• One shower + simultaneous kitchen tap
• Standard family, 2 to 4 people

CW5:

• Rain shower or bathtub
• Family of 3 to 6 people
• Increased comfort with simultaneous use

CW6:

• Two bathrooms
• Use multiple taps simultaneously
• Luxury or large family homes

Price differences per CW class (condensing boiler, 2025)

Higher CW classes require more powerful boilers with larger heat exchangers. This translates into a higher purchase price and more energy consumption.

Important considerations

• Don't choose too low: insufficient capacity leads to loss of comfort.
• Don't choose too high: an oversized boiler unnecessarily increases gas consumption and costs more.
• Get advice based on your usage, household size, and home type.
