Heat pumps are an increasingly popular, energy-efficient way to provide heating, cooling, ventilation, and hot water for homes in Ireland. By harnessing renewable energy sources—either in the ground or from the air—heat pumps can help lower your carbon footprint and reduce heating costs. However, not all heat pumps are alike, and selecting the right one can seem overwhelming.
At Unipipe, we are proud to be Ireland’s exclusive supplier of NIBE heat pumps. Since 1952, NIBE has been at the forefront of sustainable energy innovation, blending Swedish engineering with cutting-edge technology. Below, we outline the most important factors to consider before purchasing a heat pump, including how weather compensation and Quiet Mark certification can enhance performance and comfort.
1. Which Type of Heat Pump?
There are three principal types of heat pumps you are likely to come across:
-
Ground Source Heat Pumps
These extract solar energy stored in the ground to provide heating, cooling, and hot water. During warmer months, they can also operate in a cooling mode, making them suitable for year-round climate control. -
Air Source Heat Pumps
These capture heat energy from the outside air and convert it into warmth for your home. Ireland’s relatively mild climate makes air source heat pumps a popular, cost-effective choice. -
Exhaust Air Heat Pumps
These systems recycle the heat from warm indoor air as it is vented outside. They capture this outgoing heat to provide additional heating or hot water.
The right solution for you depends on factors such as your home’s size, insulation level, available outdoor space, and budget.
2. Prioritising Energy Efficiency
A heat pump’s efficiency is usually measured by its Coefficient of Performance (CoP)—the ratio of heat output to the electricity input. The higher the CoP, the more efficiently the unit can convert a small amount of electricity into useful heat. However, efficiency does not only hinge on the heat pump itself; correct sizing, installation quality, and helpful features like weather compensation are also pivotal.
Why Weather Compensation Matters
Weather compensation technology automatically adjusts the heat pump’s output based on outdoor temperatures. Rather than running at a constant rate, the system supplies only the heat required at the time. This is particularly advantageous in Ireland’s variable climate, as it stabilises indoor comfort while preventing needless energy use.
3. Advanced Features to Look For
In addition to weather compensation, modern heat pumps often come with features that further improve performance, reliability, and convenience:
-
Variable-Speed Motors
These modulate the compressor’s power usage according to demand, helping to optimise both energy efficiency and indoor comfort. -
Programmable Thermostats
Allow you to automate temperature settings throughout the day, reducing energy waste. -
Timers & Built-In Control Systems
Provide precise control over when the heat pump operates, based on your household’s schedule. -
Scroll Compressors
Known for their reliability and efficient heat transfer capabilities. -
Back-Up Burners
Supply additional heat in exceptionally cold weather, offering peace of mind.
Confirm which features each model offers—opting for newer designs can often pay off in longevity and efficiency gains.
4. Noise Levels and the Quiet Mark
Earlier generations of heat pumps sometimes had a reputation for being noisy, but improvements in design have made modern units much quieter. One way to verify a heat pump’s low-noise credentials is by looking for Quiet Mark certification.
What Is Quiet Mark?
Quiet Mark is an internationally recognised award programme that identifies high-performance, low-noise products. Heat pumps bearing this mark, including certain NIBE models, have been rigorously tested to ensure minimal disturbance. If you plan to position your heat pump near a bedroom window or in proximity to neighbours, looking for the Quiet Mark is a wise move.
5. Correct Sizing
When it comes to heat pumps, bigger is not necessarily better. An oversized system can lead to short cycling and wasted energy, while an undersized one may struggle to meet your heating and hot-water demands. The right capacity (measured in kW output) depends on various factors, including:
- Insulation levels
- Total floor area
- Number and type of windows
- Local climate conditions
A NIBE Pro Installer will conduct a thorough heat-loss calculation to determine the optimal size for maximum comfort and efficiency.
6. Costs and Grants
The cost of a heat pump installation varies based on:
- System Type & Features: More advanced models, such as those with weather compensation or variable-speed motors, may cost more initially.
- Size & Capacity: Larger systems carry a higher price tag.
- Installation Complexity: For example, ground source installations typically involve more involved groundworks than air source systems.
In Ireland, you may be eligible for grants from the Sustainable Energy Authority of Ireland (SEAI), which can substantially reduce your up-front costs. Always factor in the price of professional installation when budgeting, as a properly set-up system pays you back through better performance and lower operating costs.
7. Brand Reputation
When you are investing in a heat pump, it is essential to choose a reputable brand. Look for:
- Transparent warranties and after-sales support
- A track record in renewable energy
- Evidence of continual innovation
- A network of trained, trustworthy installers
NIBE has excelled in each of these areas since 1952, designing products that are both reliable and highly efficient. Unipipe’s role in bringing NIBE’s top-tier technology to Ireland ensures you will receive expert guidance, support, and a well-established local presence.
8. Maintenance and Warranty
All heating systems require routine servicing, and heat pumps are no exception. However, cheaper or poorly engineered models may need frequent repairs, eroding any initial savings. Pay attention to:
- Warranty Duration & Coverage
- Availability of Replacement Parts
- Quality of Customer Support
NIBE’s warranties are comprehensive, and NIBE Pro Installers can offer the best possible service and advice. This combination minimises downtime and secures long-term value.
9. Why Proper Installation Matters
Even the finest equipment can fail to deliver if poorly installed. That is why we recommend opting for a NIBE Pro Installer, who:
- Undergoes specialised training
- Understands the intricacies of NIBE heat pumps
- Can offer extended warranties and consistent after-sales service
Professional expertise in design, sizing, and system setup is critical in ensuring you enjoy the best possible performance and efficiency from your heat pump.

Heat Pump FAQs
1. What is a heat pump, and how does it work?
A heat pump extracts ambient energy from the ground, air, or exhaust air and transfers it into your home’s heating system using a refrigerant cycle.
2. How much does a heat pump cost to operate?
This depends on your chosen model, household insulation levels, and features like weather compensation. Although the initial investment can be higher than for conventional boilers, the superior efficiency often leads to lower energy bills in the long run.
3. Can I get funding in Ireland?
Yes, the SEAI offers grants that can cover part of the installation costs, making heat pumps even more economical.
4. What is weather compensation, and why do I need it?
Weather compensation automatically adjusts heat output according to outdoor temperatures, providing more stable indoor comfort and preventing energy waste.
5. What is the Quiet Mark?
The Quiet Mark is an international certification that indicates a product, including certain heat pumps, has been tested and proven to operate at lower noise levels.
6. Will I need new radiators or pipework?
In many instances, existing infrastructure can be adapted. However, a detailed assessment is often recommended to confirm compatibility or identify any potential upgrades.
