Overview

Green Flare was approached to replace the existing gas boilers at Somerset House with a renewable heating and energy system.

The client wanted to move away from gas and install an air source heating system that could provide heat for the house, hot water, and heating for the swimming pool. Previously, the swimming pool has been heated using two gas boilers, which was proving costly and was not aligned with the client's environmental goals.

The project required a carefully designed system that could support the property's energy demand while reducing reliance on fossil fuels. Green Flare designed and installed a joined-up renewable energy solution combining air source heat pumps, solar PV and battery storage.

Technology

For the heating system, Green Flare installed two Stiebel Eltron WPL 25 air source heat pumps to provide heating and hot water for the house, as well as heat for the swimming pool. This allowed the client to replace the previous gas boiler setup with a lower-carbon heating solution designed around the needs of the property.

The heating system was combined with solar PV and battery storage to help provide energy for the house. We installed 36x JA Solar 370W panels and 2x Pylontech 7.1kW battery storage units. The battery allows the client to store electricity generated during the day and use it later, rather than sending excess energy back to the grid. This helps the property make better use of the energy generated on site and supports the wider goal of reducing running costs.

The new solar PV system replaced the clients existing 15-year-old solar panels. According to the client, the new panels are around five times more productive than the previous system, making the upgrade a strong investment from both an environmental and financial perspective.

Challenges

The main challenges was designing a renewable system that could replace the existing gas boilers while still meeting the property's wider energy requirements.

This was not only about heating the house and providing hot water. The system also needed to support the swimming pool, which has previously relied on two gas boilers. Swimming pool heating can create a significant and consistent energy demand, so the system has to be specified carefully to ensure it could perform efficiently.

This project also involved assessing the existing solar PV system and whether it was still delivering strong enough performance. Although the property alrady had solar panels, the older system was no longer as productive as it could be. Green Flare's assessment showed that replacing the panels made good economic sense, with the client highlighting an estimated payback period of three to four years.

By combining heat pumps, solar PV and battery storage, Green Flare was able to deliver amore complete energy system rather than treating each technology separately.

“We were very lucky finding Green Flare. We talked to a variety of people, and with Green Flare we found Tom and Matt, who really understand what they're doing.

Various schemes were proposed, and when we finally came up with the right solution, we were extremely happy with it. I have to say the analysis they providing was spot on.

We had existing solar panels, but we did wonder whether they were as productive as they could be. The new panels are about five times more productive than the 15-year-old panels we had, so it made good economic sense to replace them.

The payback period may be three, maybe four years, but very good. Green Flare have come good. I can recommend them. You can trust them. They're knowledgeable, experienced, and if you've got the money to invest, it's a good place to invest"
