Vaillant Heat Pumps: Efficiency
The efficiency of Vaillant heat pumps shines with A+++ energy ratings and SCOP values hitting 5.03, meaning they deliver more than five times the heat output from the electricity input.
This high Seasonal Coefficient of Performance makes them a top choice for renewable energy in the North East’s variable conditions. For example, the aroTHERM plus 7kW model achieves a COP of 5.0 at 35°C flow, ideal for underfloor heating or low-temp radiators.
In real terms, this can slash annual heating costs by 50-60% compared to gas boilers, based on 2026 UK tariffs. Local factors like your home’s insulation and outdoor temps in Newcastle play a part, but integrating solar PV via the app boosts savings further. Check your EPC rating to unlock the full potential of these air-to-water systems.
Vaillant Air Source Heat Pump Range of Models
The Vaillant air source heat pump range of models includes the aroTHERM series, offering monobloc and split configurations for flexible UK installations with a focus on high-temperature output and low noise. These air-to-water units are designed for both residential and light commercial use.
Here’s a table detailing the range:
| Model Series | Key Variants | Capacity (kW) | Refrigerant | Flow Temp (°C) | Noise (dB) | Best Use |

| aroTHERM perform | Monobloc | 15-20 | R290 | Up to 70 | 50-60 | Larger properties |
| aroTHERM pro | Monobloc | 5-11 | R290 | Up to 65 | 45-55 | Space-efficient installs |
| aroTHERM Split | Split | 5-15 | R290 | Up to 63 | 45-61 | Retrofits |
Vaillant Heat Pumps: Costs

Which? Ratings for Vaillant Heat Pumps
Which? ratings praise Vaillant for high efficiency and build quality, positioning them as a leading option in independent UK heat pump tests.
Vaillant vs Other Brands
Vaillant heat pumps lead in quiet efficiency and UK support, but comparisons show distinct edges for North East applications. This section explores unique angles for internal linking.
Vaillant vs Cosy 6
Vaillant beats the Cosy 6 with superior SCOP (5.03 vs 4.5) and higher flow temps for radiator compatibility, suiting larger Tyne and Wear semis. Cosy 6 is more compact, but Vaillant’s extended warranty offers better longevity.
Vaillant vs Aira
Vs Aira, Vaillant delivers higher outputs (up to 20kW) and R290 refrigerant for eco-credentials. Aira’s all-inclusive service appeals to hands-off owners, yet Vaillant’s local installer network shines in Newcastle.
Vaillant vs Panasonic
Panasonic includes air quality features, but Vaillant’s 41dB quietness and 75°C temps make it preferable for older North East homes. Both are smart, but Vaillant’s heritage ensures stronger regional support.
Vaillant vs Nibe
Nibe excels in sub-zero performance, while Vaillant’s affordability and app controls suit milder winters. For commercial retrofits in the North East, Vaillant’s monobloc ease reduces setup time.
Vaillant vs Samsung
Samsung offers seamless smart home links, but Vaillant’s higher COP and Quiet Mark certification provide more savings in variable climates. Landlords favour Vaillant for durable multi-property installs.
Vaillant vs Mitsubishi
Mitsubishi is built for extremes, yet Vaillant’s lower GWP refrigerant and grant fit make it more accessible. In Tyne and Wear, Vaillant’s UK network edges out for quicker service.
Vaillant vs Viessmann
Viessmann matches precision engineering, but Vaillant’s quieter models and higher temps suit compact gardens better. Efficiency-focused homeowners in the North East lean towards Vaillant.
Vaillant vs Worcester Bosch
Worcester Bosch has familiar UK roots, but Vaillant’s R290 and SCOP 5.03 deliver superior eco-performance. For energy-conscious landlords, Vaillant’s smart zoning wins.
Vaillant vs Hitachi
Hitachi powers big spaces, while Vaillant’s compact designs fit urban North East plots. Colder snaps favour Vaillant’s reliability over Hitachi’s app focus.
Vaillant vs LG
LG heat pumps excel in connectivity, but Vaillant’s flow temps and support network outperform for radiator-heavy homes. Green adopters in Newcastle choose Vaillant for its natural refrigerant.
Vaillant vs Daikin
Daikin offers strong global tech, yet Vaillant’s UK-specific quiet operation and installer network provide better local value. For North East retrofits, Vaillant’s high-temp capability edges it for older properties.
