Sundial S & Y plan
S and Y plans have been designed to give you close control of both system and regular boilers fitted with a hot water cylinder, ensuring that your heated water is diverted to the correct areas. S and Y plans are also a way to ensure that your boiler interlock works. An S-plan is a better technical solution, and gives greater flexibility - since extra zones can easily be added (called S-plan-plus).
Unlike most general plumbing & heating companies we carry out the fault diagnosis & installation in house which results in a much quicker turnaround & reduced costs compared to paying sub contractors.

"I have used CH4 (Luke) before and have no problems recommending them for any work required relating to gas engineering, heating and plumbing and full fit out of bathrooms. What you will get is impartial advice on what you have requested and what they think is required. As the project progressed there was many unforeseen events. What separates CH4 is their ability to deal with problems there and then and provide you with the information required in a timely manner. The ability to work around issues and can-do attitude most probably derives from the years within the armed forces."
