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 Honiton: From Combi Boilers to System Boilers

Combi Boiler

Combi boilers, or combination boilers, are the most commonly used type of boiler in the UK for domestic hot water and gas central heating.

One of the key advantages of a combi boiler is its high efficiency, as it only heats water when a hot tap or shower is used, eliminating the need for a separate water storage cylinder or tank in the loft. This design helps save space and ensures optimal energy usage for heating water on demand.

System Boiler

A system boiler operates by pumping hot water to both the radiators and a sealed hot water storage cylinder. One of the advantages of this type of boiler is that most major components of the heating and hot water system are integrated within the boiler itself. This makes installation more straightforward, minimizes clutter, and improves overall efficiency. Additionally, servicing is simplified with this design.

Furthermore, system boilers are recognized for their outstanding environmental credentials, alongside their high efficiency and performance levels.

Regular Boiler

Heat-only boilers, also known as regular or conventional boilers, are characterized by having a small expansion tank and a larger cold water storage cistern in the loft space. If you are replacing an old boiler and currently have this type of setup, chances are you have a heat-only boiler.

Heat-only boilers are typically used in open vented systems, where two tanks are usually present in the loft space. This type of boiler is designed to work in conjunction with a separate hot water cylinder, providing hot water for taps and showers, as well as supplying water to the radiators.
