Summary of Contents for HEAT HERO DIRECT
- Page 2 Understanding Solid Fuel Boilers A solid fuel boiler can achieve twice the heat of an oil or gas boiler and will not turn off automatically. Efficiency can only be achieved with strong circulation and fast heat transfer. This is not possible when an open vent is installed in front of the circulating pump or a heat exchanger is installed on the solid fuel boiler.
- Page 3 HEAT HERO DIRECT DESCRIPTION Heat Hero Direct operates at 0.7 par of pressure and has strong circulation. It is designed to control single or dual solid fuel heating systems and directly circulate the water from the solid fuel boiler to the radiators and DHW with out the use of an Heat exchanger. Safety is guaranteed with an open vent, a built in 44KW cooling loop and an optional gravity circuit to the radiators.
- Page 4 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.
- Page 6 When Heat Hero Direct is installed the water circulates from the Solid Fuel Boiler directly to the radiators, underfloor heating and DHW without going through a heat exchanger achieving full efficiency and good heat transfer throughout the home.
- Page 7 The thermal safety valve is connected to the hot water outlet of the water heater or to the inlet of the safety heat exchanger. If the response temperature of 99 °C is exceeded, the heat expansion of the silicone oil in the probe system causes a stroke via the bellows which opens the valve to supply cooling water from the mains system.
