What is a Condensing Boiler?
A condensing boiler is a high efficiency boiler.This high efficiency is achieved by condensing water vapor (and so the name condensing boiler) in exhaust gases which recover latent heat that would otherwise have been wasted or vaporized through the flue.
What is a Combi Boiler?
A combi boiler is a type of condensing boiler that delivers both hot water and heat for your home.As it is a type of condensing boiler it will be a high efficiency boiler. If you have a combi boiler you will not need a hot water cylinder as the hot water is heated directly from the mains.

Fast, efficient, top quality
Fast, efficient top quality, would definitely recommend Jamie and will call him first if I ever need a plumber in the future.
Great and timely problem solver
Nor merely a plumber but a true Zen Master. Great and timely problem solver, mending a leaking tank and recommending the installation of a water pump to solve water pressure issues. The heating and water supply have work seamlessly ever since.
