Renewable Retrofit with Samsung Heat Pump & Battery Storage in Alnwick
Client: Private Homeowner
Location: Alnwick, Northumberland
Project Type: 4 Bed · 260m² · 2000s Detached Home
System Installed: Samsung Air Source Heat Pump & GivEnergy Battery Storage
Overview
In the historic market town of Alnwick, a homeowner decided it was time to take control of their energy future. Their spacious 260m² detached home, built in the early 2000s with underfloor heating and good insulation, was well suited for a low-carbon heating upgrade.
Eager to reduce reliance on fossil fuels and modernise their home’s energy system, the homeowner selected Geowarmth Heat Pumps Limited to deliver a smart renewable retrofit. This included installing a Samsung air source heat pump, upgrading upstairs radiators, and adding a 13.5kWh GivEnergy battery — with solar PV scheduled for installation later this year.
The Solution
By combining trusted technology with careful system design, Geowarmth delivered a solution that matched the home’s layout, size, and energy needs:
• Air Source Heat Pump:
At the heart of the new system is a Samsung Gen7 16kW air source heat pump, chosen for its high efficiency, inverter-driven performance, and quiet operation — even in cold weather. This next-generation model intelligently adjusts output based on demand, ensuring year-round comfort and minimal energy waste.
• Hot Water Cylinder:
To pair seamlessly with the heat pump, a 250L Joule unvented hot water cylinder was installed. This ensures reliable and efficient hot water delivery for the entire household.
• Heating System Upgrade:
While the existing underfloor heating on the ground floor was retained, the first-floor radiators were upgraded. Four units were replaced with high-efficiency models to work effectively with the system’s low 40°C flow temperature, maximising comfort and efficiency.
• Battery Storage:
To prepare the home for solar PV and further boost energy resilience, a 13.5kWh GivEnergy All-in-One battery was installed. This allows the household to store electricity during off-peak periods and use it when demand (and tariffs) are higher — a smart step toward energy independence.
What’s Next?
Later in the year, the homeowner will complete the renewable package with a solar PV system. Once installed, this will allow the property to generate its own electricity and work in tandem with the battery storage to reduce electricity bills and grid reliance even further.
As a result, the home will become a near self-sufficient, low-carbon property, demonstrating just how accessible and effective renewable retrofits can be.
Customer Outcome
This Alnwick-based retrofit is a great example of how modern air source heat pumps and energy storage systems can be integrated into existing homes with minimal disruption.
Thanks to the Samsung Gen7 heat pump, Joule hot water system, and GivEnergy battery, the homeowner is already enjoying a quieter, greener, and more cost-effective home — with solar energy soon completing the picture.
It’s a future-proof solution that not only supports the environment but also protects the household from rising energy prices.
