Notes:-
1. The BoilerMate 225 appliance is suitable for use in large properties because it produces the same 'peak hour output' as a typical 350-
400 litre unvented cylinder. For properties requiring the BMA 220 the incoming main should be a minimum of 32mm MDPE with
a pressure of not less than 2 bar dynamic and an adequate fl ow in line with the pipe sizing calculations. In many cases, properties
of this size will benefi t from having 2 smaller sized appliances located adjacent to the areas of peak hot water use. This will allow
2 heating zones to be provided and remove the need to provide trace heating on the hot water system.
2. A plastic feed and expansion cistern will be supplied separately including ballvalve, fl oat and overfl ow fi tting.
3. The fl ow rates are based on a 35°C temperature rise and assume normal pressure and adequate fl ow to the appliance. The actual
fl ow rate from the appliance is automatically regulated to a maximum of 28 litres/min.
4. Unit is supplied on a 100mm high installation base.
5. The domestic hot water outlet temperature is automatically regulated to approximately 52°C at the bath fl ow rate of 18 litres/min
recommended by BS 6700. The temperature is not user adjustable.
6. The designer/installer MUST calculate the suitability of the standard pump as part of normal design procedures.
7. The expansion vessel sizes have been calculated to be adequate for typical steel panel mini bore heating systems. The designer/
installer MUST check that these are adequate as part of normal design procedures and specify an extra expansion vessel if
required.
