Heat Pumps (Air & Ground Source)

Efficient Heat Pump Solutions

GPS Contractors supplies, installs and maintains high performance heat pump systems for domestic and commercial properties across the UK. Whether you are upgrading an older heating system, planning a new build or exploring renewable heating options, our specialist team designs solutions around your property, energy usage and long term goals. We manage the full process from initial assessment and system design through to installation, commissioning and ongoing servicing.

A heat pump takes heat from the air or ground outside your property and uses it to provide heating and hot water in an efficient, low carbon way. Air source systems draw heat from the outside air and suit most homes with minimal space requirements, while ground source systems extract heat from the ground and can offer higher efficiency where space and conditions allow.

Lower Carbon Impact

Heat pumps run on electricity and use free heat from the environment, producing far lower carbon emissions than gas, oil or LPG systems. As the UK electricity grid continues to decarbonise, this benefit increases over time.

Lower Carbon Impact

Lower Running Costs

When correctly designed and installed, heat pumps can be cheaper to run than older heating systems, especially in well insulated properties. Running costs depend on tariffs, system efficiency and how the system is used day to day.

Lower Running Costs

Comfort & Future Ready

Heat pumps deliver steady, even heating for improved comfort and have a long service life with fewer moving parts. They also work well alongside solar panels, batteries and smart tariffs, helping future proof your energy system.

Benefits of Heat Pumps

Lower Carbon Emissions

Air source heat pumps use renewable heat from the air and electricity rather than burning fuel. This results in significantly lower carbon emissions than gas, oil or LPG boilers, especially as the UK electricity grid continues to become cleaner.

Lower Running Costs

When designed and set up correctly, air source heat pumps can be cheaper to run than older heating systems, particularly in well insulated properties. Actual savings depend on electricity tariffs, system efficiency and how the system is used.

Lower Running Costs

Consistent Comfort

Air source heat pumps deliver steady, even heating rather than the on off cycling of traditional boilers. This creates a more comfortable and balanced indoor environment.

Long System Life

With fewer moving parts than combustion boilers, air source heat pumps can operate reliably for 20 years or more when properly maintained.

Heat Pump Installation Process

01

Consultation & Assessment

We discuss your current heating system, property type, insulation levels, usage patterns and goals to determine whether an air source or ground source system is suitable. We also consider space, noise, planning requirements and budget.

Heat Loss & System Design

A detailed survey allows us to calculate heat loss, assess existing radiators or underfloor heating and design a system that will meet your heating and hot water needs efficiently.

02

03

Proposal & Performance Modelling

You receive a clear proposal outlining equipment specifications, expected performance, indicative running costs and any recommended upgrades. We explain realistic expectations for comfort and efficiency.

Installation

Our engineers manage the full installation, including outdoor units, internal equipment such as hot water cylinders and controls, pipework and electrical connections. All work is coordinated carefully and completed safely to current standards.

04

05

Commissioning & Optimisation

We test and commission the system, optimise settings such as flow temperatures and heating curves, and show you how to use the controls effectively. Proper setup is essential for performance and low running costs. Servicing & Maintenance Ongoing servicing helps maintain efficiency, manage running costs and extend system life. We offer tailored maintenance plans for both domestic and commercial properties.

Is a Heat Pump Suitable?

Heat pumps work best in well insulated properties with heating systems suited to lower temperatures. Before recommending a system, we check key factors to ensure it will run efficiently.

• Insulation & Heating Good insulation and radiators or underfloor heating matter. Some properties need upgrades.
• Radiator Suitability Heat pumps work best at lower temperatures, so existing radiators may need improvement.
• Space & Airflow Air source systems need outdoor space with good airflow to run efficiently.
• Hot Water Use Correctly sized hot water cylinders are needed and may heat water more slowly.
• Electricity Supply Electricity tariffs and available supply capacity are important factors.

If a property is not suitable, we will explain what changes could make a heat pump a practical option.
