Renewable Energy Systems
Reduce energy costs and future proof your homes, commercial properties & developments with a renewable energy system.
Renewable Energy System Specialists
Dawson Mechanical and Renewables are specialist installers of renewable energy efficient heating systems throughout Dublin, Meath, Kildare and Louth. From heat pumps to PV solar heating solutions, we help homeowners and businesses reduce energy costs while minimising environmental impact. As SEAI-approved installers, we guide you through the entire process from initial consultation and SEAI grant applications through to installation, commissioning and ongoing servicing. Whether you’re building or upgrading to a new energy-efficient home, retrofitting an existing property, or upgrading heating in a commercial development, our renewable energy specialists deliver reliable and professional service.
Heat Pump Energy Systems
Air source heat pumps extract heat from outdoor air and work efficiently in most properties. Ideal for new builds with underfloor heating, they can also be retrofitted to existing homes with proper system design.
Air-To-Water Heat Pumps
Takes heat from the outside air and uses it to warm water for your radiators, underfloor heating and hot taps in your property. It’s very energy-efficient (around 300–400% efficiency) and a very popular heat pump choice for properties across Ireland.
Air-To-Air Heat Pumps
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.
€12,500 Heat Pump Grant
Heat pump installations qualify for a new and updated SEAI grant effective from Feb 2026, significantly reducing your up front investment while delivering long term energy savings. Check your eligibility with a free consultation.
Projects we install heat pumps include:
We partner with industry leading heat pump providers Viessmann on all our projects:
PV Solar Systems
Photovoltaic (PV) solar
Some Recent Renewable Energy System Installations
Some recently successful completed renewable projects which included air-to-water heat pumps and by using renewable energy to provide on demand underfloor heating and hot water on demand.
Renewable Energy Systems for New Builds, Renovations & 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 renewable energy systems that integrate seamlessly with building services.
Frequently Asked Questions
Choosing the right renewable energy system raises important questions. Below are answers to common FAQs about air-to-water heat pumps, air-to-air heat pumps and PV solar systems. Please reach out if you still have a question.
A renewable heating system uses natural energy sources such as air and sunlight 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 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.
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.
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
PV solar systems
Grant amounts vary depending on the property type and system installed.
