Notes..
This system is based upon a standard Indirect unit, and has the primary controls fitted.
The unit is fitted with two heat exchangers, and is capable of delivering 45 litres/minute.
The unit uses a High Duty Coil to transfer heat from the primary system into the cylinder.
The Feed & Expansion Tank can double as the boiler F&E (top-up) Tank.
The Three-Port Valve [35] is used to divert water from the boiler to the cylinder or to the heating, or both, as required.
