Good afternoon everyone,

I have an old Dunkirk, I believe Empire, boiler and it has this tankless coil installed. I cannot find replacements for it. Can someone point me in the right direction of finding a replacement?

Triangle Tube Model number ESTM

    Therma-Flow Everhot will have them. Buy them thru FW Webb or another supplier.

    I agree, Thermo flow Everhot. If they don't show one they can make one. Give them a call.

    Here's a nice replacement to consider. Give that crusty old boiler summers off for the rest of its short remaining life

    I appreciate everyone's input. I am going to check out Thermo-flow.

    Ethicalpual- The tankless coil had a leak and would set the relief valve off. So i have not been using the coil for years. One day I may upgrade to a heat pump water heater. This boiler is a tank, I think she has 10 more years left in her!

    Edtheheaterman- You always give valuable info. Thank you! It appears the person who replaced the priginal coil, never followed your advice!
