Well, what can I say, right from the very first phone call to the job being completed Gary provided a top class service. I had about 5 or 6 quotes to have a new boiler. I read through many Checkatrade reviews and Complete was one of the companies I contacted. Gary was very quick with a response, he came round had a good look at the job and provided a written quote very quickly. His pricing is very fair and his quotes are very clear. I asked Gary to do the work for me and from start to finish he was brilliant. An extremely likeable and honest chap, very hard working and a great job done. Superb!Customer in Surbiton
Combination boilers (also known as combi’s) are fast becoming the number one choice for homeowners across surrey and south London. They are low maintenance and deliver constant supplies of instant hot water. (See combi vs conventional page for the pros and cons)
Unvented cylinders are considered to be the Rolls-Royce of hot water delivery when installed alongside a system boiler. Unvented cylinders deliver mains water pressure to the whole house and eliminate the need for cold-water tanks in the loft. They require minimum 22 litres per minute of flow to work to their full potential, so good mains water pressure is essential.
Conventional / Regular boiler:
Conventional boilers are the traditional systems that have been around for years. They work alongside a cold-water tank in the loft and a hot water cylinder. They have a feed tank in the loft along with a open vent, making the system open to the atmosphere. Shower pumps can be attached to this type of system for maximum shower experience.
System boilers are the same as conventional boilers but are pressurized. This means they are fed directly from the mains water with no feed tank or open vent pipe.
