What we do

Gas Boiler
Replacements

We are experts at fitting new A rated boilers, no matter what type of boiler you require for your home our experts will provide you with a free home survey and discuss your requirements with you.

All our boilers are A rated and will provide you and your home with heating and hot water. If your current boiler is greater than 15 years old it is likely costing a lot more to run than new highly efficient boilers saving you money on your energy bills!

Oil to LPG

LPG (Liquefied Petroleum Gas) is already in thousands of homes throughout Ireland, efficiently providing central heating, hot water and cooking.

Whether you are building your own home or switching from oil to gas, LPG is a clean and efficient fuel, saving you money, and giving you peace of mind from the worry of oil theft.

Heat Pumps

Heat pumps are an efficient, reliable and sustainable way of heating your home. An air source heat pump extracts energy from the outdoor air and transfers it inside the home to provide heating and hot water all year round. The heat pumps we use are manufactured in Europe and are suitable for Irish homes and Irish weather.

Oil Boiler
Upgrades

Oil boilers have long been a popular choice for heating in off-grid homes – properties that are not connected to the mains gas supply. In rural areas or remote locations, where access to the gas grid isn’t available, oil-fired systems have offered a reliable and relatively efficient way to provide both central heating and hot water. They can be installed in a wide range of property types, from traditional cottages to larger country houses, and have historically been valued for their ability to deliver consistent heat even in colder climates. Many households have relied on oil boilers for decades, supported by regular fuel deliveries and a network of local service engineers familiar with maintaining these systems.

Solar PV & Thermal
Panels

On average, a solar PV system can save between €200-300 per year on your domestic electric bill.

PV panels don’t need direct sunlight to work. And they still produce electricity on cloudy days. Solar Panels also have a long shelf life. As the only moving part in a solar panel are the electrons, a panel will normally last about 20 years.

Dairy Farm

277

Water temperatures are consistently identified by industry experts as a critical foundation for achieving an effective and hygienic wash routine on dairy farms. Maintaining the correct water temperature is essential for removing milk residues and preventing bacterial growth. However, it’s important to note that water heating alone can account for more than 20% of a dairy farm’s total energy consumption, making it both a key performance factor and a significant operational cost.

Our happy clients

I would like to say a big thank you to everyone in your company for fitting my new Bosch Boiler in May. Everyone was so professional. They arrived on time, used plastic covers to save my carpet, answered my questions (even the stupid ones?) and got straight to work. I would highly recommend them.
