INSTALLATION INSTRUCTIONS FOR DUAL HEATING SYSTEM:

Heat Hero Direct is installed above the solid fuel boiler to allow gravity pass through the
solid fuel boiler and Heat Hero Direct.

The pipe thermostat must be of good quality and should be fitted as close to the solid fuel
boiler as per diagrams. (Caution should be taken that the heat from the stove does not
damage the workings of the pipe thermostat.)

The circulation pump should be an 8m Head pump and should be fitted beside the Heat
Hero Direct.

The Cold Feed must be connected to the Heat Hero Direct Port 5 (see page 6).

The Heating Storage Tank should be a minimum of 1m above the highest point of the
heating System (e.g. above the Heat Hero Direct or above the radiators)

Expansion pipe of minimum ¾ “ diameter must be connected to the Heat Hero Direct Port
6 (see page 6) and piped to the heating tank as per diagram.

The Non return Valves should be of good quality and installed as per the diagram.

Auto air vents should be of good quality and installed as per the diagram.

Blow off valves should be installed at the secondary heat source.

Heating Zones If a heating system is zoned, At least one radiator zone must open
automatically when the solid fuel thermostat turns on the circulating pump.

Pressurised Cylinder Heat Hero Direct can be connected with solar and a DHW
pressurised cylinder safely and efficiently.

44KW Cooling Loop is built into the Heat Hero Direct. If the solid fuel boiler heats above
99° the liquid filled temperature probe will open the thermal safety valve and mains water
will cool the gravity circuit and the solid fuel boiler.

With Heat Hero Direct a solid fuel boiler, pressure cylinder, solar and oil or gas boiler can
operate fully efficiently together within the manufacturers recommendations.
