Air Source Heat Pump Installer in St Helens
Expert installation of air source heat pumps with personal service and high-quality workmanship
What Are Air Source Heat Pumps?
Air source heat pumps are renewable heating systems that extract heat from the outside air to warm your home and provide hot water. Even in cold weather, there is heat energy in the air that can be captured and used efficiently.
Unlike traditional gas or oil boilers that burn fuel to create heat, heat pumps move existing heat from one place to another using electricity. This makes them significantly more efficient and environmentally friendly.
Flow Energy specializes in installing high-quality air source heat pump systems across St Helens and surrounding areas, with personal service and attention to detail throughout the installation process.
How Air Source Heat Pumps Work
Heat Extraction
The outdoor unit absorbs heat energy from the air, even at temperatures below freezing.
Compression
The refrigerant is compressed to increase its temperature, making it hotter.
Heat Transfer
The heated refrigerant transfers its heat to your home's heating system and hot water.
Cycle Repeats
The process repeats continuously to maintain your desired temperature.

The Survey: What to Expect
Before any installation can be booked, a detailed heat loss survey of your property is required. This is a technical assessment — not a basic quote visit — and is the foundation of a correctly designed system.
What the survey includes
- Room-by-room heat loss calculations for your property
- Assessment of insulation, windows, and construction type
- Correct sizing of radiators where upgrades are needed
- Full system design completed after the survey
- Firm installation price confirmed once design is finalised — installation can then be booked
The survey ensures your system is designed correctly first time, helping maximise efficiency and performance.
Why is the survey chargeable?
- ·It takes several hours on site plus design time afterwards
- ·It is a technical assessment, not just a basic quote visit
- ·It ensures the system is correctly sized and efficient
- ·It prevents undersizing or oversizing — both of which reduce performance and increase running costs
Important: all initial quotes are estimates only
Any figures provided before the survey — including online estimates — are indicative only. Your final installation price will be confirmed in writing after the survey is completed. The survey cost is deducted in full from your installation price if you choose to proceed.
What the Installation Involves
A typical heat pump installation takes around 4–5 days from start to finish
Heat Pump, Pipework & Hot Water Cylinder
The outdoor unit is positioned and secured, primary pipework is run between the unit and the plant area, and the hot water cylinder is installed. This is the core of the system and is completed in the first two days.
Radiator Upgrades (if required)
Heat pumps operate at lower flow temperatures than gas boilers, so some radiators may need to be upgraded or replaced to ensure the system heats your home effectively. Where required, this work is carried out during days two to four.
Commissioning, Testing & Controls
The system is fully commissioned, all connections are tested, and the controls and thermostat are configured to suit your home and lifestyle. You will be walked through how to operate the system before we leave.
What Disruption Should You Expect?
We understand that having work carried out in your home is never entirely convenient, and we aim to keep disruption to a minimum throughout the process.
Hot water availability
Hot water may be off for up to 2–3 days during the installation while the new cylinder and pipework are connected. We will always let you know in advance when this is likely to occur so you can plan accordingly.
Access to different rooms may be required at various stages, particularly where pipework or radiators are being worked on. Our installer will keep you informed throughout and tidy up at the end of each working day.
Aftercare & Follow-Up
Our commitment to you does not end when the installation is complete. Approximately one week after handover, we carry out a follow-up check to make sure the system is performing as expected and that you are comfortable using it.
Depending on your system and circumstances, this may take the form of a phone call combined with remote monitoring data, or an in-person visit. Either way, the purpose is the same: to confirm performance, answer any questions, and ensure you are fully satisfied.
If anything is not right, we will address it promptly. Your satisfaction and the long-term performance of your system are what matter most.
