Systems Explained

Could not recommend Garry and his team more highly. He is unusually personable in the plumbing trade and what was most impressive was that he also made himself available when things beyond his control from subcontractors did not come up to par and he put them right quickly. Nothing is too much trouble with Garry. His commitment to us being completely satisfied was outstanding. We would use him again. Wish there were more tradesmen like him out there.

	Combination boilers 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 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 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.
