Combination (combi) Boiler
The Combination boiler from Vaillant is also known as the ‘Combi’, where this type of boiler does two things, heats water and provides central heating. The Combi boiler heats water as you draw it from the tap, with no need of a water storage tank as the boiler is connected directly to the water mains, meaning it only heats water as and when needed.
Properties with limited space are the perfect home for a combi boiler. Combi boilers are cost effective and energy efficient, as well as compact. They are also one of the most popular boiler types fitted in the UK today.

System Boiler
The system boiler are also known as sealed system boilers with the heating system built into the boiler itself. These type of boilers are ideal for homes with more than one bathroom, as they provide a constant supply of hot water to many taps at the same time.

Regular Boiler (open vent)
The regular boiler provides central heating and hot water through a hot water storage cylinder. They are also sometimes known as an open vent boiler. The cylinder is often found in an airing cupboard and the cold water tank is usually found in the loft. Open vent boilers are perfect for a home that has multiple bathrooms as they can provide a lot of hot water at the same time. They work well if you are replacing an exisiting open vent heating system, and are ideal if the water pressure in your area is low.

Recent work
We installed this Vaillant boiler to replace an aging boiler that had been there for many years in a property in Sawbridgeworth, Herts. This new design of boiler ensures water is heated much faster, using less gas, and the Magnaclean filter protecting the whole system from metal and carbon deposits.
We worked in a large property in London providing our client with a whole new heating system, pipework and Vaillant boiler.
DSB recently installed a new Vaillant combination boiler to a property in Ware. This boiler was to replace an old boiler and hot water cylinder, gaining more cupboard space and increasing the water pressure.
