    HEAT HERO High Efficiency open vented Solid Fuel Heating System

    Well spotted that man, the unit is correctly labelled, but they certainly got the diagram wrong. How could you trust a company that can't even get its own descriptions correct? Can those reviews be genuine, not if they connected the "Heat Hero" the way they show.

    HEAT HERO High Efficiency open vented Solid Fuel Heating System

    From their description I can't see what it does that a four way and three way junction and a few flow control valves and setting up on temperature flow and return would not do? Are the internals thermostatically controlled?

    Heatslave 20/25 lockout

    Testo 327-1 replacement sensors

    Purged again and the O2 is down to the IM normal 2.1, will take some more readings with this unit on a known burner and see if the sensor goes to the depleted warning again, if it does I will use the cleaner and report back what happens.

    Testo 327-1 replacement sensors

    Only one of my 327 units was saying "Warning O2 cell depleted" I purged the unit and the message disappeared and it now calibrates and works again, so may have to wait a while to clean one, one thing I noticed is the ambient O2 is at 2.2 and not 2.1 as the other two, will purge again and see...

    Riello RDB cutting out

    Check you are getting 50V from the motor to actuate the solenoid valve, usually the black and white wires into the control box. See page 19 here: https://www.rielloburners.co.uk/images/content/downloads/RDB1-2_2902489-18.pdf
