Reliable hot water systems
Reliable hot water designed around your home.
A reliable hot water system should provide consistent hot water while operating efficiently in the background. We design and install hot water systems tailored to each property, ensuring they are correctly sized and integrated with the wider heating and energy system. Hot water systems can work alongside air source heat pumps, solar thermal, solar PV and central heating systems as part of a complete home energy solution. Services could include:
- Hot water cylinder installation and upgrades
- Unvented and vented hot water systems
- Hot water systems for heat pumps and boilers
- Controls, pumps and system components
Integration with solar thermal and renewable technologies

Our process
Every hot water system is designed around the demands of the property. From initial assessment through to installation and commissioning.
01.
We begin by understanding your property, existing system and daily hot water demand. This allows us to identify the most suitable solution and any improvements that may be required.
02.
The system is carefully designed around the property's requirements, including the selection of the appropriate hot water cylinder, controls and associated components. All equipment is specified to ensure compatibility, efficiency and reliable performance.
03.
Installation and system updates
Our in-house team installs the complete system, including cylinders, controls, pipework and associated equipment where required. Any necessary upgrades are carried out to ensure the system operates safely and efficiently.
04.
Handover and ongoing support
Once installed, the system is fully tested and commissioned to confirm everything is operating correctly. We then guide you through the system and provide advice on getting the best performance from it.
Trusted technology partners.
These partnerships allow us to specify proven equipment from established brands, ensuring systems are designed for long-term performance.

Very professional service, the lads did a chemical flush on our boiler & upgraded the pipe from the meter to the boiler. Mathew & Daniel were prompt, courteous & very professional. The work was a carry on from our boiler repair. I recommend their service & if required will definitely use PCL in the future.

Absolutely brilliant service from PCL. The engineers were polite, professional, and completed the work efficiently in less than a day and a half. They left the house spotless after finishing, which was a great touch. Couldn’t be happier with the quality of work—highly recommend.

Everyone was very helpful and informative, providing advice not just on the basics of running the system, but also on how to tweak the system and improve performance as we get to know it. This was a major financial commitment on our part, so to have such an excellent team of installers was very reassuring. We would recommend this company to anyone looking to install greener energy systems.

Most recently, they installed air source heating, solar panels, battery storage and a Vaillant heating system. For this new build, they also completed all plumbing and electrical work. The whole team is skilled, knowledgeable and reliable, including the apprentices, and the office team communicates well throughout. Phil and his team have been reassuring to work with and are always responsive, whether it is an emergency or a smaller job.
