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 225 the incoming main should be a minimum of 32mm MDPE with
a pressure of not less than 2 bar dynamic and an adequate flow in line with the pipe sizing calculations. In many cases, properties
of this size will benefit 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, float and overflow fitting.
3. The flow rates are based on a 35°C temperature rise and assume normal pressure and adequate flow to the appliance. The actual
flow 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 flow rate of 18 litres/min
recommended by BS 6700. The temperature is not user adjustable.
