What can I replace R8182D with?

Hello. I recently lost hot water/heat and trouble shot it down to the aquastat. Power comes in, thermostats energize relay, but no power ever gets to the burner or circulator. A replacement for one of these is stupidly expensive, and I've been unable to find much information on what can replace it. I see many people reference a 8184, which can be replaced by a much newer R7284(and its only $75..) from what I gather, but I can't find anything about compatability with what I have.

If you guys could help me out I'd appreciate it.

    Unfortunately, you need a new aquastat and primary control.
    A Honeywell L8124A, or a Hydrostat 3250 Plus for the aquastat. Any primary with a 15 second safety will do. Honeywell, Carlin, Beckett, etc. The 8184G is a 45 second safety.
    Sounds like your doing the job yourself. Do you have a combustion analyzer?

    Based on what?
    Parts cost what they cost, and professionals deserved to get paid to install them.
    You need a competent professional to choose the proper replacement, wire it correctly, put it into service, checking the safeties to make sure they work properly.

    I think Beckett makes an AquaSmart/GeniSys kit that can replace this control. Going this way would bring your unit up to current standards- 15-second trial for ignition, 2012-compliant energy savings etc. BUT, you need to have a pro install it.

    Please don't do this yourself.

    There have been many DIYers who are no longer here and sometimes killed their loved ones to save $100. This is a combination safety device and requires a knowledgeable person to correctly rewire the unit and PROVE the safeties work.

    What you should do as an informed consumer is make sure they test the High Limit and Burner Safety before leaving, ask them to demonstrate.
