Overview – A Holistic Home Energy Upgrade in Gosforth

This mid-century detached home in Gosforth, Newcastle upon Tyne, demonstrates how a holistic approach to home energy can dramatically improve:

Efficiency
Comfort
Long-term running costs.

The homeowners wanted more than simply replacing their ageing gas boiler. Instead, they wanted to future-proof their home by integrating renewable heating with clean electricity generation, intelligent battery storage, and electric vehicle charging.

Working closely with the customer, Geowarmth designed a complete home energy solution where every technology complements the others.

By combining a Vaillant air source heat pump, solar PV, Eleven Energy sodium battery storage, and the property’s existing EV charger, the household is now able to generate, store and intelligently manage its own energy throughout the year.

This project highlights why an integrated renewable energy system delivers significantly greater benefits than installing each technology independently.

The Solution – One Integrated Renewable Energy System

Rather than viewing heating and electricity as separate systems, Geowarmth designed every component to work together.

The result is a home that consumes less energy, generates its own electricity, stores surplus generation, and uses that energy where it provides the greatest value.

Vaillant aroTHERM Plus 12kW Air Source Heat Pump – Premium German Engineering

The existing gas boiler was removed and replaced with a Vaillant aroTHERM Plus 12kW air source heat pump, providing renewable heating and hot water for the entire property.

Vaillant has been manufacturing heating systems for more than 150 years and has become one of Europe’s most respected heating brands.

The aroTHERM Plus represents the latest generation of heat pump technology, combining exceptional efficiency with ultra-quiet operation and environmentally friendly R290 natural refrigerant, which has one of the lowest Global Warming Potentials (GWP) available.

Why Homeowners Choose Vaillant

Outstanding seasonal efficiency
Quiet operation for residential environments
Natural R290 refrigerant
Proven German engineering
Reliable cold-weather performance
Excellent long-term reliability

As a Vaillant Renewable Partner, Geowarmth has demonstrated the highest standards of installation, commissioning and aftercare.

This gives customers the reassurance that their system is installed by manufacturer-recognised specialists and enables access to Vaillant’s extended 7-year manufacturer’s warranty.

New 300L Vaillant Unvented Hot Water Cylinder – Designed for Heat Pump Performance

To complement the new heating system, a 300-litre Vaillant unvented hot water cylinder was installed within a newly constructed cupboard.

The new plant area provides a neat, purpose-built solution while ensuring the household has plenty of stored hot water to meet the demands of a busy four-bedroom family home.

Designed specifically for renewable heating systems, the cylinder works efficiently alongside the heat pump to provide reliable hot water all year round, whilst giving homeowners greater control and visibility over their heating system.

Solar PV – Generating Clean Electricity Every Day

To reduce reliance on grid electricity, Geowarmth installed:

10 × 450W all-black JA Solar panels
Total peak generation of 4.5kWp

The all-black panels complement the property’s roof while producing clean renewable electricity throughout the year.

The electricity generated can power:

The heat pump
Household appliances
The battery storage system
The home’s existing EV charger

Every unit of solar electricity consumed within the property helps reduce electricity bills while lowering carbon emissions.

Eleven Energy Sodium Battery Storage – The Next Generation of Home Energy Storage

To maximise the value of the solar generation, the homeowners chose 18kWh of Eleven Energy sodium battery storage paired with an Eleven Energy inverter.

Sodium-ion battery technology is rapidly becoming one of the most exciting developments in residential energy storage.

Unlike conventional lithium batteries, sodium batteries use abundant raw materials and offer excellent long-term durability, making them an increasingly attractive choice for homeowners.

Why Eleven Energy Is Growing in Popularity

Eleven Energy has quickly established itself as one of the UK’s most innovative home energy storage manufacturers by focusing on safety, intelligent energy management and future-ready technology.

Key homeowner benefits include:

Excellent cycle life
Outstanding thermal stability
Enhanced safety characteristics
Reduced reliance on lithium supply chains
Intelligent energy management software
Scalable storage capacity
Designed specifically for modern renewable homes

The battery system automatically stores excess solar energy during the day before supplying that electricity back to the home during the evening, overnight or during expensive peak-rate periods.

During winter months, when solar production naturally reduces, the system can also charge from low-cost overnight electricity tariffs before discharging that energy during higher tariff periods.

This intelligent strategy further reduces household electricity costs while helping offset the running costs of the heat pump.

As a trusted Eleven Energy Partner, Geowarmth provides expert system design, installation and ongoing support, ensuring customers get the very best performance from their battery investment.

Why a Holistic Home Energy Approach Delivers Better Results

Many homeowners begin with a heat pump or solar panels alone. However, the greatest benefits are achieved when renewable technologies are designed as one complete system.

Benefits of an Integrated Renewable Home

Lower overall energy bills
Reduced carbon emissions
Greater energy independence
Less reliance on fluctuating electricity prices
Intelligent use of solar generation
Lower heat pump running costs
Future-ready home for electric transport
Increased property value

Rather than simply replacing a boiler, this Gosforth project has transformed the property into a smart, efficient energy ecosystem.
