Air Source Heating


When it comes to renewable energy, Grant Plumbing Services offer a range of air source and hybrid heating systems.
We supply, install, service and commission Grant UK and Mitsubishi Air Source Systems. Both these companies manufacture outstanding renewable energy systems.
Heat pumps – usually air source or ground source – are modern, low carbon heating systems that are much more energy efficient than boilers and traditional electric heating. 21% of the UK’s carbon emissions come from our homes, with three quarters coming from our heating and hot water. This means that heat pumps will continue to play a crucial role in meeting net zero carbon targets and addressing the climate emergency.

Air Source Heating – Design – Supply – Install – Commission – Maintain & Service
Air source heating systems, also referred to as air-to-water heat pumps, represent a form of renewable energy technology utilised for heating and providing hot water in residential properties across the United Kingdom.
These innovative systems function by harnessing heat from the external air and utilising it to warm water, which is subsequently distributed throughout the building’s heating infrastructure.
The process of installing an air source heating system typically encompasses the following sequential stages:
It should be noted that the installation of an air source heating system generally necessitates a larger initial investment when compared to conventional heating systems.
Nevertheless, in the long run, this expenditure is often offset by the system’s heightened efficiency and reduced operational costs. Additionally, it is important to mention that the air source heating system qualifies for the Renewable Heat Incentive (RHI) scheme, which is a government initiative that provides financial support for the adoption of renewable heating solutions.
Why choose a Grant Aerona air source heat pump?
With outputs of 6kW, 10kW, 13kW and 17kW the Aerona³ R32 heat pumps are designed to maintain a reliable and consistent heat output, even at low outdoor air temperatures.
What’s more, these compact and efficient units have an impressive ErP rating of A+++ across the range.
Hybrid Heating Systems
We supply, install, service and commission Air Source & Oil Combined systems.
Hybrid Heating Systems – Design – Supply – Install – Commission – Maintain & Service
Hybrid heating systems represent a fusion of multiple heating technologies, incorporating elements such as a boiler and an air source heat pump. These systems leverage the most suitable heating source according to prevailing weather conditions and the specific heat requirements of the structure, thus delivering an efficient and cost-effective approach to heating.
The installation process for a hybrid heating system typically encompasses the following stages:
Hybrid heating systems offer efficiency, flexibility, and the potential for cost savings compared to conventional heating systems.
Moreover, they qualify for the Renewable Heat Incentive (RHI) scheme, which constitutes government-backed financial support for renewable heating solutions.
