in Oil Heating
Hi forum. 1st post/discussion/question here so please go easy. We have a Riello RDB oil burner outside in our yard. We've recently had it serviced and parts replaced and it has been working well however it has recently lost water pressure. I'm scared to adjust any of the valves as last time I did that I broke one of the parts (hence service and new parts). does anybody have any idea how I can add water pressure ? hugely appreciated. James

    The RDB is the burner, not the boiler, correct? I didn't know that burner was available in the U.S.
    More info is needed. Is this a pool heater, or for space heating? Pics?

    If you recently had it serviced, I would call the person back. It's possible there is a leak. Have them explain how to fill/bleed/purge the system, and what pressure it should operate.
    -Could be the gauge doesn't work or sticks. I had a customer showing 0 psi, started adding water and in 2 seconds the pressure jumped to 30 and the PRV blew.
