This technologically advanced, versatile mains pressure water heater is ideal for localised use. The Europrisma can be used where hot water is required but where it is not convenient to enlarge the existing central hot water system or where there is no central system at all. Examples of such situations are small industrial units, warehouses, dentists' and doctors' surgeries, cafés, and certain residential situations, e.g. additional bathrooms, loft conversions, etc.

Installation Using Pipe to Accommodate Expansion
Current Water Regulations and Byelaws permit unvented water heaters with capacity of 15 litres or less to accommodate the expansion of water that occurs during the heating cycle in the system pipe work. To achieve this the pipe work between the last cold water draw off and the water heater must be of sufficient volume to accommodate the expansion.
Installation Using an Expansion Kit
If it is not possible to accommodate the expansion in the system pipe work, it is then necessary to use an expansion vessel and non-return valve (Kit A). If the mains water pressure may exceed 3.5 bar a pressure reducing valve (Kit B) should also be installed. The discharge from relief valves must be made in a safe and conspicuous manner; therefore a tundish (Kit C) is available for 10 and 15 litre units if required.
