Firebird super Q 85/115 (kerosene) query...

    I have a firebird super Q 85/115 with a Riello G5X burner (indoor boiler) using Kerosene. This year I have replaced the nozzle/flange insulation/flex hose/oil filter... while cleaning out the boiler there was a lot of red debris/dust in the chamber and around the baffles, I couldn't remove the baffles (possibly running at too high a temp warped the baffles), anyway I cleaned any loose debris that had built up using the vacuum cleaner, I have dumped the vacuum cleaner bag and filter when finished cleaning the boiler but there is a lot of red dust in the vacuum cleaner hose!
    Question 1: Is there any health risk from the (red)debris/dust inside a boiler that burns kerosene?
    Question 2: Can I add a hot water cylinder thermostat to a one pump system and still keep the rads hot? Our central heating systems has one circulating pump with a boiler thermostat, the hot water cylinder in the hot press was running too hot (I have adjusted the thermostat calibration screw to reduce the running temp but will add a stat to the hot cylinder if it works)

    Were a dust mask when cleaning the boiler. I am not aware of any health risk from the dust but my view is that it is a by product of combustion and my mentor always told me to "keep your mouth out of that dust". That's strange about the baffles though. I usually tap them with a hammer and pull with a grips if they are stuck. Have you being putting the right nozzle back into it. If the nozzle is to big it could be over heating the chamber or maybe the oil pressure is to high on the pump. This is checked at the pump with an oil pressure gauge. Yes you can fit a cylinder stat to the cylinder and have it controlling a zone valve.

    I agreement with Johnniek.
    Would add that servicing the boiler is fairly straight forward but you should set it manufactures recommendation regarding oil pressure and nozzle size ( dependent on the duty you require 85,000- 115,000 BTUs). Your boiler may be oversized/rated and could be overheating as it can not desipate the heat to the water so your baffles are warping.
    Also you must use an flue gas analyser.
    This will show you discharge temp and CO2 levels etc.can only properly adjust the oil pressure and air mix/ settings with an analyser.
    Inaccurate oil/ air mix can result in too high temperature and excesive oil usage.
