Very professional, efficient, reliable and friendly service. Appointment made within 2 weeks. Engineer arrived on time. Very knowledgable about heat pumps. Identified several installation faults (not installed by Synergi) which were clearly explained. Follow-up report sent the same afternoon. I would highly recommend Synergi for servicing heat pumps.

Lisa searched for many months for a reliable plumbing and heating contractor to install a combi boiler and heating in her new house and was very relieved to find Synergi (SW) Ltd. This was a challenging project but we were reassured by their professional approach and advice. Their highly efficient operatives attended on due date and after careful inspection of the site were soon on the job. We cannot praise them highly enough, they were awesome. Thank you Synergi for a job well done and excellent value for money.

Fantastic service! Our old boiler finally gave up on us and we had our new boiler installed within 48hours! All the engineers were very friendly and efficient. Jay in particular was incredible. He put in extra effort to get the installation done in such a small time window. We were very grateful as we have 2 young children. We would 100% recommended Synergi SW to anyone.

This company is a family business run properly who have really gone out of their way to sort our problems for us (including dropping everything when we had an emergency gas problem and coming straight over). We have used them to sort our underfloor heating, solar collector and associated electrics. Highly recommended.

I would just like to express my gratitude to Simon, for all his hard work yesterday. He came to install 2 new radiators at my house, but ended up having to spend longer removing large quantities of air that had built up in the system. My thanks to Joe aswell for helping at the end of the day to get my rather old heating system back up & running again. My house hasn't been this warm in years! You are both extremely hard working, tidy & professional! Thank you.

New Boiler Sidmouth: From Combi Boilers to System Boilers

Combi Boiler

A combi boiler, also known as a combination boiler, is a type of central heating and hot water system that is commonly used in UK homes. As the name suggests, it combines both the functions of a water heater and a central heating boiler in one compact unit.

Unlike traditional heating systems that require a separate hot water tank, combi boilers heat water directly from the mains when a hot tap or shower is turned on. This means that they are highly efficient and can provide instant hot water on demand, while also saving space and reducing energy consumption.

System Boiler

A system boiler is a type of central heating boiler that works in conjunction with a hot water storage tank to provide heat and hot water to a home. Unlike a combi boiler, which heats water directly from the mains on demand, a system boiler stores hot water in a cylinder or tank, which can then be used for showers, baths, and other household needs.

System boilers are often used in larger homes with multiple bathrooms, as they can provide a high flow rate of hot water to multiple outlets simultaneously. They are also highly efficient, as they can be used with renewable energy sources such as solar panels to reduce energy bills and carbon emissions.

Regular Boiler

A regular boiler, also known as a conventional or traditional boiler, is a type of central heating system that requires both a hot water storage tank and a cold water storage tank. The system heats water in the central heating system and stores hot water in the cylinder, which is then distributed to taps and showers around the home.

Regular boilers are often found in older homes, and they are popular for their ability to provide a strong, consistent flow of hot water. However, they can be less energy efficient than newer boiler types, and they require more space for installation due to the separate tanks.
