R290 Heat Pump Technology in Ireland: Why Viessmann Vitocal Heat Pumps Lead the Way

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.

What Is an R290 Heat Pump?

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.

Why R290 Heat Pumps Are Ideal for Irish Homes

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

Viessmann Vitocal R290 Heat Pumps Explained

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.

Key Features of Viessmann Vitocal R290 Heat Pumps

• 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.

R290 Heat Pump Efficiency and Running Costs

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.

R290 Heat Pump Retrofit vs New Build

New Builds

• Ideal match for low-temperature heating systems

• Achieves A-rated BER with ease

• Supports future carbon-neutral targets

Retrofits

• 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.

Safety and Design of Viessmann R290 Systems

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.

SEAI Grants and R290 Heat Pumps in Ireland

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.
