Vented and Unvented Hot Water Cylinders


In addition to regular hot water cylinders, there are two types of unvented hot water cylinder:

an umbrella type, which has a built in diaphram for expansion; and the other is

an external expansion kit suited to the size of cylinder required.

They are mains cold water systems which are not fed off a tank and generally form part of a fully pressurised system, which have greater hot water flow rates and hold the heat better than an open vented cylinder.

The general requirement for this type of installation is an annual check to make sure that all the components are functioning satisfactorily.

CSPM Plumbing and Heating can carry out such checks for all properties within the Southend-on-Sea area.
