System design support

The key to a successful renewable heating system installation is thorough planning and preparation. Air source heat pumps, for example, can achieve their maximum potential if the complete system has been designed correctly. This includes ascertaining a property’s heat loss to identify the correct heat pump model and output through to selecting the most suitable heat emitters to compliment the heat pump’s low temperature operation.

While there is a lot to think about when planning a heat pump installation, Grant UK is here to help customers whether it be with onsite support, technical assistance or product specification. Our in-house Design Team is on hand to discuss your upcoming renewable heating projects – whether you are in the initial planning phase and need to discuss the solutions available or whether you need support with heat loss calculations and quotations, the Design Department can help you.

Heat emitters to complete a system

Selecting the right heat emitters for a renewable installation is just as important as choosing the heat source technology itself. Air source heat pumps operate at lower temperatures compared to traditional fossil fuel heating systems so they require heat emitters with larger surface areas. This is why underfloor heating is such a popular choice to work alongside heat pumps because it is effective and delivers complete comfort.

Other heat emitter options are available for heat pumps. Grant UK’s range of heat emitters provides choice so that customers can choose the products which best meet their requirements while still achieving excellent performances. From underfloor heating through to fan convectors and aluminium radiators, we have it covered.

Renewable Heat Incentive

To encourage and support homeowners with the transition of heating their home with renewable energy, the Government’s Domestic Renewable Heat Incentive (RHI) issues eligible installations with quarterly payments over seven years. Through the RHI, householders can earn a financial return on their renewable heating system  – for example, a Grant Aerona³ 13kW air source heat pump could earn an estimated annual RHI payment of £1,300 which could total in excess of £9,000 over the duration of seven years.

Homeowners looking to apply for the RHI must meet the Scheme’s criteria which includes selecting an eligible renewable heating system (all of Grant’s heat pumps, hybrids and solar thermal systems are eligible) which needs to be commissioned and certified by a MCS accredited installer.

Combining heating technologies

For over four decades, Grant Engineering have been researching, designing and developing efficient heating systems to meet the changing needs of all our homes. This has resulted in the comprehensive range of products that Grant UK can supply to customers today. While each individual product is exceptionally efficient in its own right, when multiple heating technologies are partnered and installed together, a home’s overall efficiency can be taken into a new class.

For example, installing an Aerona³ air source heat pump with a Grant ‘A’ rated MonoWave 200 litre cylinder and a Sahara two collector solar thermal system, a combined package efficiency of A+++ could be achieved for the whole heating system. Consequently, by installing more than one heating technology, homeowners can not only significantly reduce their carbon footprint but also their energy bills.
