Are you deciding between a heat pump and a central heating boiler? The available space in your home plays a significant role in this choice. Here’s what you need to know:
-
Heat Pump:
- Requires more space due to an indoor unit, outdoor unit, and possibly a buffer tank.
- Outdoor unit requires sufficient distance from neighbors (at least 3 meters) and produces 40-60 dB(A).
- Suitable for well-insulated homes (minimum energy label C).
-
Central Heating Boiler:
- Compact and fits in small spaces such as a storage room or attic.
- No outdoor unit needed and easy to install.
Quick Comparison
| Feature | Heat Pump | Central Heating Boiler |
|---|---|---|
| Installation Space | Indoor and outdoor space needed | Indoor space only |
| Noise | 40-60 dB(A) (outdoor unit) | No outdoor noise |
| Insulation Requirement | Minimum energy label C | No specific requirement |
| Buffer Tank | 50-500 liters (depending on type) | Not needed |
For new constructions or major renovations, a heat pump offers advantages, while a central heating boiler is ideal for existing homes with limited space. Read on for more details.
Heat Pump Basics
A heat pump is a system that extracts heat from the outside air or ground and converts it for use in your home. Instead of generating heat itself, a heat pump transfers and amplifies existing heat sources.
Heat Pump Types
Below are the different types of heat pumps with their dimensions:
| Heat Pump Type | Indoor Unit (w x h x d) | Outdoor Unit (w x h x d) | Buffer Tank |
|---|---|---|---|
| Air-to-Water | 60 x 85 x 50 cm | 100 x 80 x 40 cm | 50-300 L |
| Air-to-Air | 90 x 30 x 20 cm | 80 x 55 x 30 cm | Not needed |
| Water-to-Water | 70 x 180 x 60 cm | None (does require ground source) | 200-500 L |
| Hybrid | 60 x 85 x 50 cm | 90 x 60 x 35 cm | 50-200 L |
Indoor and Outdoor Space Requirements
For a complete installation, a technical space of at least 2 m² is needed. Ensure 75 cm of workspace around for maintenance. The indoor unit should be placed in a ventilated and frost-free area, with additional space possibly needed for a buffer tank. The piping requires a diameter of 10-15 cm. The outdoor unit should be placed at least 3 meters from property boundaries, on a sturdy surface or wall mount, with ample free space for air circulation.
Placement Requirements
Noise Insulation:
- The outdoor unit produces 40-60 dB(A).
- Sound-absorbing materials may be necessary to limit noise nuisance.
- Place the unit at least 2 meters away from bedroom windows.
Technical Requirements:
- The home must be well insulated (minimum energy label C).
- Low-temperature radiators or underfloor heating are required.
- The system must be tailored to the size of the home.
To optimize the heat pump's performance, it is important to have it installed by a certified installer. This takes into account technical details and local regulations. Read on for the installation requirements of central heating boilers.
Basic Information About the Central Heating Boiler
Let’s take a look at the compact design and installation of a central heating boiler, a popular choice in Dutch households.
Types of Central Heating Boilers
In the Netherlands, HR combi boilers, Solo HR boilers, and VR boilers are commonly used. These systems are known for their compact size and minimal space requirements.
Space Requirements
Thanks to its compact design, a central heating boiler can easily be placed in a small, dry, and well-ventilated area. Consider locations such as the attic, a technical room, utility room, or storage room.
Simple Installation
The design of a central heating boiler makes the installation straightforward and efficient. Here are two key advantages:
- No outdoor unit needed.
- Extra space for a buffer tank or control equipment is unnecessary.
This makes the central heating boiler a practical choice, especially in renovations where available space is limited.
Space Requirements: Heat Pump vs. Central Heating Boiler
Let’s compare the space needed for a heat pump and a central heating boiler.
A heat pump has multiple components that collectively take up more space:
- Indoor Unit: The size varies per model. Additionally, extra space is needed for pipes and control panels.
- Outdoor Unit: This needs to be placed separately, with enough distance from windows, property boundaries, and noise-sensitive areas (at least 3 meters).
- Buffer Tank: If present, it requires additional space.
Central heating boilers, on the other hand, are much more compact. They can be easily installed in small spaces, such as a storage closet or attic, as long as there is a safe flue gas outlet and good ventilation.
When choosing a system, available space is an important factor. For new builds or large renovations, a heat pump can be more easily integrated into the plans. But in existing homes with limited space, a central heating boiler is often a more practical choice.
The next section provides more details and advice to help you make the right decision.
Conclusion
When choosing between a heat pump and a central heating boiler, available space is a key consideration. A central heating boiler is often a practical choice for homes with limited space, due to its compact design. It is essential, however, that there is adequate ventilation and a suitable flue gas outlet.
A heat pump requires careful placement. The outdoor unit should be positioned to avoid noise disturbance and allow for good air circulation. Indoors, additional space is needed for the technical components.
