Offaly self-build features renewable heating designed by Grant

The self-builder of a new NZEB family home in County Offaly is experiencing high comfort and low energy bills with the help of a new renewable heating system from leading Irish home heating solutions company Grant.

With a focus on sustainability and reducing environmental impact, self-builder and paediatric nurse Katie Grogan wanted to future-proof her family home and ensure it remained warm and comfortable for many years to come.

Katie’s contractors contacted Birr-based heating specialists Grant, and the team went through the house plans, calculating the heating requirements for each room and correct sizing of all recommended heating technologies, which resulted in a bespoke integrated package that included home heating design, specification and supply. Katie chose the Grant Aerona³ R32 air-to-water heat pump which provides building regulations compliance and “an energy efficient, sustainable and cost-effective way to heat a property”, according to Grant.

“The technical team at Grant literally took care of everything and provided our contractors with a home heating plan for every room which included layout maps which were an absolute godsend for the build,” Katie says. “I was also able to use the maps myself dozens of times when I was talking to kitchen designers, electricians, plumbers. It made it so much easier as all the trades knew exactly what was going on.”

With an ErP rating of A+++, the Aerona³ R32 range is available in outputs of 6 kW, 10 kW, 13 kW and 17 kW and the units can help to achieve nearly zero energy building (NZEB) standards, as required by all new build properties in Ireland. Katie also opted for Grant Uflex underfloor heating across two floors, a Grant pre-plumbed hot water cylinder and Grant wireless smart controls. Grant’s pre-plumbed hot water cylinder range is designed to heat water faster and more efficiently than standard cylinders and ensure hot water is available 24/7.

Katie says: “When we planned the house with the architect they went through our options in terms of heating and we realised that an air source heat pump was the way to go, coupled with underfloor heating in each room. We did have the options of radiators as well, but we preferred underfloor heating as it meant we didn’t need to worry about placing furniture in front of radiators and gave us more freedom over the design of the interior. For us, the most important things were comfort and cost.” The family has also seen a reduction in their heating bills, added Katie. “We’ve seen them cut by two-thirds, which is amazing.”
