Dedicated to providing comprehensive calculations which enable the correct specification of sustainable heating technologies and relevant supporting products, Grant is leading the way with its free-of-charge professional heating design service.

Designed bespoke

Developed with architects, specifiers, BER Assessors, heating engineers and builders in mind, the service is helping to save significant time on new build projects and reassure contractors and homeowners that each heating system has been designed bespoke for each property.   

Commenting on the continued success of the Grant heating design service, Barry Gorman, national renewables sales manager at Grant said: “We have been offering our heating design service to professionals within the heating industry for several years now and are delighted to see so many availing of the service throughout Ireland.

"As a company, it is a priority for us to ensure that our heating technologies can be specified and installed with minimal effort for the heating engineer. This is why we offer the services that we do, whether it be the free of charge home heating design service or indeed our range of product awareness and installation training courses.”

Maximum efficiency

Throughout every new build project, Grant’s technical specialists work closely with the contractors involved in the building of the property to ensure a fully integrated heating package is designed with correctly sized and specified heating technologies. This careful combination, sizing and specification of technologies is vitally important to ensure the heating system performs at maximum efficiency.

When carrying out a new-build project in Ireland, installing a highly sustainable main heat source like an air to water heat pump is now essential in order to meet required building compliance.

When a heat pump like the Grant Aerona3 R32 air to water air source heat pump is chosen, then full heat loss calculations in line with SR:50 requirements are recommended. These calculations are included as standard by the technical specialists at Grant as part of the home heating design service. 

In addition to providing the heat load requirement for each room, which helps to calculate the output of the air to water, air source heat pump, the Grant team also correctly size and specify complimentary technologies for each individual build including supporting technologies like the Grant integrated unit, hot water cylinder range and heat emitters for each room in the home whether that be radiators, and / or underfloor heating.
