Heat Pump Energy Systems
Heat pumps are the most popular renewable heating technology in Ireland, providing efficient heating and hot water for residential and commercial properties.
Air Source Heat Pumps
Air source heat pumps extract heat from outdoor air and are suitable for most properties. Modern air source systems work efficiently even in cold weather and can provide heating, cooling, and hot water. They’re ideal for new builds with underfloor heating and can be retrofitted to existing properties with careful system design. Types of air source heat pumps (ASHP) include:
Air-To-Water: Takes heat from the outside air and uses it to warm water for your radiators, underfloor heating, and hot taps. It’s very energy-efficient (around 300–400% efficiency) and is the most popular heat pump choice for homes across Ireland.
Air-To-Air: Takes heat from the outside air and uses it to warm the air inside your home through wall-mounted units or discreet indoor fans. Instead of heating water for radiators, it blows warm air directly into the room, making it a quick and responsive way to heat a space.
We install heat pumps for:
- New build homes with MVHR ventilation systems
- Existing home retrofits replacing oil or gas boilers
- Extensions requiring efficient heating solutions
- Commercial and development projects
- Schools and educational buildings
- Healthcare and medical facilities
Our heat pump installations qualify for SEAI grants, significantly reducing your
upfront investment while delivering energy savings over the longer term.
PV Solar Thermal Systems
Solar thermal panels provide hot water using free energy from the sun, reducing your reliance on oil, gas, or electricity. They work year-round in Irish conditions and can supply up to 60% of your annual hot water needs. SEAI grants are available for residential solar thermal installations, making this an affordable addition to your renewable energy system. Solar thermal systems integrate perfectly with:
- Heat pump installations for hot water boosting
- Existing boiler systems as a complementary technology
- New build homes as part of overall renewable energy strategy
- Commercial buildings with high hot water demand
Renewable Energy Systems for New Builds and Developments
Renewable energy systems play a key role in meeting current building regulations and energy performance targets. We work closely with developers and project teams to design and install air to water heat pumps, air to air heat pumps, and solar panel systems that integrate seamlessly with building services.

Frequently Asked Questions
Choosing the right renewable energy system can raise a few important questions. Below are answers to the most frequently asked questions about air to water heat pumps, air to air heat pumps, and solar panel systems. These FAQs will help you understand how each technology works, what benefits they offer, and how to get the best performance from your renewable energy investment.
A renewable heating system uses natural energy sources such as air, ground, sunlight or biomass to heat your home. It reduces carbon emissions and lowers long-term energy bills compared to oil or gas boilers.
Common systems in Ireland include:
Air source heat pumps
PV Solar thermal systems
Air to water heat pumps extract heat from the outside air and transfer it to a water-based system for central heating, underfloor heating, or hot water cylinders. Air to air heat pumps, on the other hand, transfer heat directly to indoor air to provide heating or cooling. Air to water is ideal for whole-house heating, while air to air is suitable for rapid room temperature control and smaller spaces.
An Air source heat pump extracts heat from the outside air and transfers it indoors to heat your radiators, underfloor heating and hot water.
It works by:
Absorbing heat from outdoor air
Compressing it to raise the temperature
Releasing the heat into your home
Air source heat pumps can be 300–400% efficient.
The main difference is where the heat comes from:
An air source heat pump collects heat from the air.
A Ground source heat pump collects heat from underground pipes.
Ground source systems are usually more efficient but cost more to install.
Yes. Both heat pumps and solar panel systems reduce reliance on traditional electricity and gas, which can significantly lower energy costs. Heat pumps are highly efficient, often providing three units of heat for every unit of electricity used, while solar panels generate free electricity from sunlight, reducing grid consumption.
Air to water heat pumps work best in well-insulated properties because they operate at lower water temperatures compared to conventional boilers. Older homes can still use heat pumps, but improving insulation, window efficiency, and underfloor heating or larger radiators may be necessary for optimal performance.
Most solar panel systems last 25–30 years with minimal maintenance. Occasional cleaning to remove dust or debris, along with periodic performance checks, is usually sufficient. Battery storage systems may require additional monitoring and servicing depending on the technology.
Absolutely. Air to water heat pumps and solar panels can be integrated with existing boilers or heating systems to provide hybrid solutions. This allows homeowners or commercial clients to gradually transition to low-carbon energy while maintaining reliable heating and hot water supply.
A Solar thermal energy system uses roof-mounted panels to capture sunlight and heat your domestic hot water.
In Ireland, solar thermal:
Reduces hot water energy costs
Works year-round (with a backup system in winter)
Is often paired with a heat pump or boiler
Yes, homeowners in Ireland can apply for grants through the Sustainable Energy Authority of Ireland (SEAI).
Under the Better Energy Homes Scheme, grants are available for:
Heat pumps
Solar thermal systems
Insulation upgrades
Grant amounts vary depending on the property type and system installed.
