1.2 TECHNICAL DATA

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.  [Ask for report - Unvented v’s Integrated Thermal Storage].  [Please note that this model requires 

 

a larger cupboard and a 686mm wide door].  For properties requiring the BM 225 the incoming main should be a minimum of 

 

35mm 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 a secondary circulation 

 

on the hot water system.

2.   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.   Models will be available in Hard and Soft water versions (suffi xed ‘H’ or ‘S’).
5.   Unit is supplied on a 100mm high installation base.
6.   The domestic hot water outlet temperature is automatically regulated to approximately 55°C at the bath fl ow rate of 18 litres/min 
 

recommended by BS 6700.  The temperature is not user adjustable.
