Energy Efficiency

Heat pumps are highly energy-efficient systems, capable of transferring heat from one location to another rather than generating heat directly.

Dual Functionality

One of the significant advantages of heat pumps is their ability to provide both heating and cooling functions using the same system.

Consistent Comfort

Heat pumps provide consistent heating and cooling throughout the year, maintaining a comfortable indoor temperature regardless of external weather conditions.

Environmental Friendliness

Heat pumps utilise renewable energy sources such as the heat present in the air, ground, or water, making them environmentally friendly heating and cooling solutions.

Long-term Savings

Although the initial cost of purchasing and installing a heat pump may be higher than that of conventional heating and cooling systems over the course of an average year, heat pumps save our clients about 20-40% on their annual heating and cooling bills.

Long-life Span

Heat pumps can have a long lifespan of up to 50 years, with the average being about 14 to 15 years. They are exceptionally reliable and steady, offering a safer alternative to combustion-based heating systems.

Increase Your Home's Value

Heat pumps increase your property value. A well-designed heat pump system, installed within a smart home and maintained by a trusted, professional home energy specialist, can significantly boost the sale value of your home and other properties.


Other advantages include serving both heating and cooling functions, saving space as they don’t require fuel storage, requiring no planning permission, and being silent and unobtrusive.



Heat pumps work by taking natural warmth out of the surrounding environment to provide hot water and heating to your home. There are three main types of heat pump: ground source, air source and water source. The name of each one describes where the appliance takes its heat from, and, therefore, each one works in a slightly different way.


Before anything else can happen, the heat must first be collected. Depending on the type of heat pump, the heat will be absorbed by a refrigerant either from the ground, air or water source. This takes place in the evaporator with the refrigerant changing from liquid to gas in the process.


The refrigerant is now a gas instead of a liquid and the gas is compressed to increase its temperature even more. It is this heat that can be used to warm up your radiators or underfloor heating.


As the refrigerant transfers the heat that is to be used in your home’s heating system, it gradually cools down and condenses back into a liquid. This occurs in a second heat exchanger. One of the reasons why heat pumps are so efficient is because cooler water from the central heating can continue to absorb the heat from the liquid refrigerant within this second exchanger.


Once the refrigerant has cooled right down, it passes through an expansion valve. In here, the liquid’s pressure is decreased and it returns to the evaporator to begin the whole cycle again.


They can be ideal whether you are looking for a heating system for a new build or a renovation, and they can be operated in conjunction with solar thermal systems to bring further cost savings and environmental benefits. In addition, they can be combined with an existing gas or oil heating system to form a multi-mode system. This enables every building and property owner to implement their plans in the most efficient way possible.










 Commercial NDMG Solar PV Scheme

New funding ranges from €2,700 to €162,600 to support an even wider range of businesses to switch to solar. This will typically support 20-30% of the investment cost, reducing payback to as little as 5 years. New Solar PV Scheme enhancements will boost business investment in renewable energy generation

Domestic Solar PV Grant

A grant is available to all owners of dwellings built and occupied before Dec 2020 and where SEAI have not previously provided support for solar PV system at that address. How much you can receive from the grant is dependant on the size of the system that was installed. A grant of up to 2,400 euros is available for a solar PV which is installed on your property.

TAMS3 For Farms

In February 2023, the Minister for Agriculture announced the latest TAMS project, TAMS 3, which includes a significant initiative: grants for the installation of solar panels and batteries. All of the electricity generated from the installation of Solar PV on farms must be used for agricultural purposes. gives further information of the eligible items and their associated costs.

EV Home Charging Grant

Claim up to €600 towards the purchase and installation of an electric vehicle home charging unit. When Combined with a solar PV system you can use the green energy generated from your solar panels at home to charge your electric vehicle in the most efficient and sustainable way. Friendly on the environment and your pocket!
