CONVENTIONAL BOILER SYSTEM

With this type of system hot water cannot be provided on demand but must be stored, usually in a copper cylinder (usually located in an airing cupboard) and a cold water tank above it (usually in the attic) as well as a smaller central heating header tank (also usually in the attic).

As the water is pre-heated and stored, it can be used by more than one tap at a time without significant loss of flow. The Conventional system is particularly suited to the larger property with more than one bathroom or where mains water pressure is too low for an instantaneous appliance such as a combination boiler.  

From April 2002, changes in the Building Regulations effect how your installer replaces your boiler/cylinder or makes changes to your heating controls.   Click here for more information Click here for more information

There are various ways in which conventional systems can be improved.

> Boiler renewal. Old boilers can be renewed for improved performance, safety and economy.
> Powerflushing to remove accumulated sludge coupled with installation of pressurisation kit (the header tank is removed) for improved filling and circulation. Click here for more information
> Upgrade to pre-lagged, high efficiency conventional cylinder for faster heat up and economy.
> Upgrade to unvented hot water. The large cold tank and cylinder are removed and a special cylinder installed. Click here for more information
> Change to continuous hot water. All 3 tanks are removed and a combination boiler replaces the existing conventional boiler.
> Controls upgrade for separate time and temperature control of central heating and hot water for improved economy and comfort control.
