Air Source Heat Pump Installation Northern Ireland.
Air source heat pumps designed for real-world performance, with systems built around proper heat loss calculations, low-temperature design and professional commissioning.
We design and install air source heat pump systems for homes and commercial buildings across Northern Ireland, focusing on heat loss calculations, low-temperature heating design and proper commissioning.
More Than Just Fitting a Heat Pump
Our Approach.
Air source heat pumps only perform properly when the entire heating system is designed correctly.
Poorly specified installations can lead to high running costs, inconsistent heating and disappointing results. At Newell Heat & Power we take a design-led approach, starting with the building’s heat loss and heating performance rather than simply selecting a unit.
A Design-Led Approach to Heat Pumps
We design air source heat pump systems around accurate heat loss calculations, emitter sizing and system flow temperatures rather than simply selecting a unit size.
By focusing on the building fabric and heating distribution, we ensure systems operate efficiently, deliver consistent comfort and achieve strong seasonal performance.
Designed for Low-Temperature Efficiency
Air source heat pumps operate most efficiently at lower flow temperatures. Our systems are designed to work within these parameters, delivering steady and comfortable heat without the spikes and inefficiencies associated with traditional high-temperature heating systems.
Real-World Performance
TOP of The SCOP’s.
We have the Highest Performing Monitored Heat Pump System in the UK & Ireland with Over 500% Seasonal Efficiency.
Independently Verified Heat Pump Performance
At Newell Heat & Power, we focus on designing heat pump systems that deliver strong performance in real homes, not just theoretical efficiency figures.
One of our installations is independently monitored through HeatpumpMonitor.org, an open-source platform used across the UK and Europe to share and compare real-world heat pump performance data.
Over the last 12 months, this system has achieved a seasonal performance factor (SPF) of over 5.0, meaning the heat pump produces more than five units of heat for every unit of electricity used – equivalent to over 500% efficiency.
Based on the publicly available data, the system currently sits at the top of the monitored performance charts, demonstrating what can be achieved when heat pumps are properly designed and commissioned.
Why This Matters
High seasonal performance isn’t achieved by the heat pump alone. It depends on the design of the entire system, including:
• Accurate heat loss calculations
• Correct heat pump sizing
• Low-temperature heating design
• Proper hydraulic balancing
• Careful commissioning and optimisation
This design-led approach is what allows systems to deliver low running costs, consistent comfort and proven long-term efficiency.
