Tankless coil replacement

Plumberman860 · February 24

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?

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

Maybe get a Tap n Die set too.

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

After replacing the coil, with a new red rubber gasket, be sure to go back after 500 hours of operation (maybe 3 to 5 months) go back and snug up on the bolts, and then again at 1 year. That is something no one does… ever. and then the coil gasket starts to leak in 4 years and looks like $#!T in 7 years.

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!
