An air-source heat pump is an efficient and eco-friendly way of heating your home without the need for a traditional gas or electric heating system. If you want to reduce your current heating bills while doing your bit for the environment, then read on to find out how you can achieve this with an air source heat pump.
As Ireland accelerates its transition away from fossil fuels, the R290 heat pump has emerged as one of the most efficient, future-proof heating solutions available. At the forefront of this technology is the Viessmann Vitocal range, delivering exceptional performance, high flow temperatures, and ultra-low environmental impact—specifically engineered for the demands of Irish homes.
This article explores why R290 heat pumps, and in particular Viessmann Vitocal heat pumps, are rapidly becoming the preferred choice for homeowners, installers, and specifiers across Ireland.
An R290 heat pump uses propane (R290) as its refrigerant. Propane is a natural refrigerant with outstanding thermodynamic properties and a Global Warming Potential (GWP) of just 3, compared to over 2,000 for many traditional refrigerants.
Key advantages of R290 include:
Extremely low environmental impact
Higher seasonal efficiency (SCOP)
Excellent performance in cold climates
Capability to deliver high flow temperatures up to 70°C
These characteristics make R290 heat pumps ideal for both new builds and retrofit projects in Ireland.
Ireland’s housing stock presents a unique challenge: a high proportion of existing homes with radiator systems designed for oil or gas boilers. Many homeowners assume heat pumps are unsuitable for retrofit—this is no longer the case.
A Viessmann R290 heat pump can operate efficiently at higher flow temperatures, allowing it to work seamlessly with upgraded radiators or even existing systems in many cases.
Benefits for Irish homes include:
Reliable heating performance at outdoor temperatures as low as -22°C
Reduced need for invasive underfloor heating retrofits
Lower running costs compared to oil and gas
Full compliance with SEAI grant requirements
The Viessmann Vitocal heat pump range, particularly the Vitocal 150-A , represents a new generation of R290 air source heat pumps designed for real-world conditions.
Flow temperatures up to 70°C without electric backup
Advanced scroll compressor technology
Exceptionally quiet operation—ideal for urban and suburban settings
Integrated 7” HD touchscreen controller
Built-in energy monitoring and internet connectivity
Smart grid and PV-ready functionality
These features position Viessmann as a market leader in R290 heat pump technology in Ireland.
Efficiency is a critical ranking factor for homeowners researching heat pumps. Viessmann Vitocal R290 units deliver:
SCOP values exceeding 5.0 (system dependent)
Lower electricity consumption per kWh of heat produced
Optimised defrost cycles for damp Irish winters
When combined with correct system design—heat loss calculations, radiator sizing, and weather compensation—running costs can be reduced by 50–70% compared to oil boilers.
Ideal match for low-temperature heating systems
Achieves A-rated BER with ease
Supports future carbon-neutral targets
High flow temperatures enable compatibility with radiators
Reduced disruption compared to older heat pump systems
Excellent option for replacing oil or LPG boilers
Viessmann’s R290 heat pumps are specifically designed to bridge the gap between traditional heating and renewable technology.
While propane is flammable, Viessmann has engineered its Vitocal R290 heat pumps with multiple safety layers, including:
Factory-sealed refrigerant circuits
External monobloc design
Continuous refrigerant monitoring
Compliance with all EU and Irish safety standards
This makes Viessmann R290 heat pumps safe, reliable, and installer-friendly.
Homeowners installing a Viessmann R290 heat pump may qualify for SEAI heat pump grants, subject to eligibility and system design.
Typical grant benefits include:
Up to €6,500 for heat pump installation
Additional supports for insulation upgrades
Long-term reduction in energy costs and carbon emissions
Choosing a premium system like Viessmann ensures compliance with SEAI technical standards and long-term performance assurance.

With high efficiencies, high flow temperatures, and ultra-low environmental impact, they are ideally suited to both modern homes and older properties.
For homeowners seeking a future-proof, grant-supported, and high-performance heating solution, a Viessmann R290 heat pump is one of the strongest investments available today.
As Ireland accelerates towards a low-carbon future, R290 heat pumps have emerged as the most advanced and sustainable heating option for Irish homes. Among all available solutions, the Viessmann Vitocal R290 heat pump range stands out for its exceptional efficiency, low environmental impact, and suitability for both new builds and retrofit projects. Homeowners, installers, and specifiers searching for the most future-proof heat pump technology in Ireland increasingly rely on R290 systems for long-term performance and regulatory compliance.
The defining feature of an R290 heat pump is the use of propane (R290) as its refrigerant. Unlike synthetic refrigerants such as R410A or R32, R290 offers an extremely low Global Warming Potential (GWP ≈ 3). This places it far below the limits of upcoming F-Gas regulations, making it one of the most environmentally friendly refrigerants available today.
Key advantages of R290 heat pumps include:
Ultra-low GWP, future-proofing systems well beyond 2030
Higher efficiency, even in colder Irish climates
Flow temperatures up to 70 °C, ideal for retrofits with existing radiators
Improved operational performance and reduced running costs
Compliance with Ireland’s SEAI and Part L requirements
Because of these benefits, searches for R290 heat pumps in Ireland have grown rapidly—reflecting rising demand for heating systems that deliver comfort, sustainability, and long-term savings.
Viessmann is one of Europe’s most respected heating manufacturers, and its German-engineered Vitocal 150-A Standard R290 & Vitocal 150-A Compact heat pumps represent the next generation of air-to-water technology.
