The answer to your home heating needs
Building a new home and finding the perfect heating system can be daunting, however, Grant can help make the process hassle-free by providing the full home heating solution using products from their extensive portfolio.

Aimed at helping those designing or building a new home, Grant’s Multiple Package Solutions includes a free of charge home heating design service which identifies the heating requirements of the property, followed by full product specification and supply.

Using their specialist knowledge and experience in identifying the full heating requirements of the property, the Grant technical team can also maximise efficiencies through the combination of different technologies including the highly efficient Grant Aerona3 R32 air source heat pump, Grant pre-plumbed hot water cylinders and modern heat emitters including Grant Uflex underfloor heating, Grant Afinia aluminium radiators and Grant Solo fan convector radiators.

Features & Benefits
Whether you are a homeowner or work within the trade and are planning a new build project, there are number of important choices to make including the size and scale of your design, construction materials required, types of finishes available and of course, selecting the best home heating system. It not only delivers greater overall efficiencies and long-term savings but also helps you meet environmental standards outlined in building regulations. Helping to ease the process Grant provide the full home heating solution by combining specialist knowledge with an extensive product portfolio. Following an easy process, you can save time and have the property’s full heating requirements designed, quoted and supplied by Grant.

Availing of the free of charge design service, you can learn more about how combining an Aerona³ heat pump with other products in the manufacturer’s innovative product offering can help your heating system achieve optimum efficiencies.

Grant Aerona³ R32 Air Source Heat Pump Range | Grant Ireland

Features & benefits
The new Grant Aerona³ air source heat pump uses R32 refrigerant which has a significantly lower Global Warming Potential (GWP) than other typical refrigerants. R32 is a single molecule refrigerant which removes the risk of temperature glide. The enables the system to recharge and recycle with greater ease thus leading the system to be more efficient. The Aerona³ R32 is our most efficient heat pump to date but still incorporates all the features and benefits of our existing Aerona³ range such as DC inverter driven, built in weather compensation and base tray heating element to prevent against freezing.

How the Aerona³ Heat Pump works
Air source heat pumps use basic thermodynamic principles to convert thermal energy contained within the air we breathe to heat energy that can be used to provide heating and hot water. This “ambient heat” is replenished by the sun making our heat pumps both effective and environmentally friendly. How the Heat Pumps work Grant Aerona³ heat pumps use an air to water system which uses energy absorbed from the air and transfers it to a water based heating system. The process uses the same vapor/compression cycle that extracts heat in a domestic fridge. A refrigerant with a low boiling point is exposed to external air temperatures in an evaporator. The liquid boils off to a gas and absorbs the thermal energy of the air.  This gas is then compressed increasing the heat energy contained within the refrigerant, before passing through a heat exchanger where it condenses back to a liquid form, whilst transferring the heat to the water of the heating system. The liquid refrigerant is then re-circulated through the evaporator and the cycle is repeated.

Fit for the Future
With the recent fluctuations in price and supply of fossil fuels, air source heat pumps offer both an environmentally and economically sustainable alternative. Home heating accounts for approximately 30% of CO2 emissions. The heat source used by Grant Aerona³ heat pumps is entirely renewable which helps reduce the amount of harmful greenhouse gases being released into the atmosphere and, in doing so, lowers the carbon footprint of the household.

Lower Heating Costs
Compared with other domestic heating methods, the Grant Aerona³ can benefit homeowners by creating annual savings on fuel bills. The units can deliver over four times the amount of energy for every 1kW of electricity used depending on the flow temperature and the climate conditions prevailing at the time. Homes utilising this type of heat generator will obviously have a lower dependency on fossil fuels, making them less susceptible to rising fuel costs.
