The demand for unvented systems continues to increase as their benefits are recognised
by specifiers, installers and end users. The new Multipoint 75 and 100 litre units offer
unvented water heater performance and are quicker and easier to install.
Based on the highly successful Multipoint range, the new 75 and 100 litre models are
designed to significantly reduce installation time. These wall mounted units are supplied
factory-assembled with all necessary valves and controls pre-installed ready for
connection to the mains services resulting in a much easier, faster and neater installation.

04 Features and benefits
Multipoint 75/100
Multipoint 75/100 are ideal for commercial applications such as
cloakrooms, kitchens or washrooms, where a single heater is
required to service multiple draw-offs. Both products may also
be used for single point showering and are available with 6kW
rating (2 x 3kW elements) for use in locations where faster hot
water recovery is required.*
As with all unvented units above 15 litres, it is a Building
Regulation requirement that installers are competent to install
Multipoint 75 and 100 litre units. This normally means having
successfully completed a course in unvented systems.
