04 Features and benefits
Multipoint 10/15
FOR UP TO THREE BASINS
Multipoint is the market-leading range of small unvented water heaters and is ideal for any situation where a single heater is required to service the needs of multiple outlets. Multipoint is supplied with a factory-fitted temperature and pressure relief valve, is quick and easy to install and is offered in a wide range of capacities and ratings. High-grade copper is used for the Multipoint inner container because of its optimum performance in terms of durability and corrosion resistance. Copper requires no sacrificial anode and therefore avoids the need for regular inspection and replacement. Unlike other lesser grade materials, it also withstands shock and vibration during delivery, installation and maintenance. 10 and 15 litre capacities Choice of 3kW and 4.5kW ratings Five-year inner container guarantee Replaceable long-life alloy-sheathed element Externally adjustable thermostat 10°C to 70°C max. - lockable in hot or mid-range position CFC/HCFC free (ODP zero) flame-retardant expanded polystyrene Element ‘On’ indicator No anode to inspect or replace Suitable for use with any standard mixer or tap Fitted with 1 metre of 3-core cable Comprehensive installation instructions BEAB and kiwa approved to UK water supply regulations IPX4 Rated Multipoint 10/15 selection matrix Capacity

Multipoint 30/50
FOR UP TO SEVEN BASINS
Multipoint 30/50 are ideal for commercial applications such as cloakrooms, kitchens or washrooms, where a single heater is required to service multiple draw-offs. The 50 litre product may also be used for single point showering. Versions of both products are available with 1kW elements for use in locations where electrical loading is restricted (horizontal unit 3kW only). Multipoint 30 and 50 units are supplied complete with necessary installation accessories. A thermostatic blending valve can also be used. See page 06 for details. As with all unvented units above 15 litres, it is a Building Regulation requirement that installers are competent to install Multipoint 30 & 50 litre units. This normally means having successfully completed a course in unvented systems. For details on training courses call 0845 600 7402 or 01362 853091. 30 and 50 litre capacities Choice of

Hotflo
FOR UP TO THREE BASINS
The Hotflo range sets a new standard in value for money, small unvented water heating. It features an inner container with integral element for increased reliability and quick, easy replacement. Hotflo is suitable for a wide variety of point-of-use applications and a full range of accessories is available to ensure Hotflo can be installed in any situation. High-grade copper is used for the Hotflo inner container because of its optimum performance in terms of durability and corrosion resistance. Copper requires no sacrificial anode and therefore avoids the need for regular inspection and replacement. Unlike other lesser grade materials it also withstands shock and vibration during delivery, installation and maintenance. 10 and 15 litre capacities 2.2kW element rating Replaceable copper inner container with integral heating element Two-year guarantee Externally-adjustable thermostat 10°C to 70°C CFC/HCFC free (ODP zero) flame-retardant expanded polystyrene. Element ‘On’ indicator No anode to inspect or replace Suitable for use with any standard tap or mixer Fitted with 1 metre of 3-core cable Comprehensive installation instructions BEAB and kiwa approved to UK water supply regulations Heat exchanger replacement Hotflo’s innovative design makes replacement of the inner container with integral element, quick and easy. The screwless construction of this range allows swift removal of the terminal cover, plug-in thermostat, neon assembly and mains cable. This permits the plastic top moulding to be detached from the steel outer case along with the pre-formed polystyrene insulation. The inner container can now be lifted clear and replaced.
