Have used Runtal UF series before and the quality is excellent. Now if they could sneak more BTUs per foot.

Triangle Tube Smart 50 - 46 Gal. - Indirect Water Heater Review Oct 01, 2016

It works good except mine started leaking all over the floor inside of 2 yrs and now my contractor says he hasn't heard from the dealer for the warranty. No drain in on the unit so I can't just move it out of my basement.

I replaced a Dunkirk XEB-3 (20 yrs. old) with the Dunkirk boiler above. The new one is all most identical to the old one, that is the pipes were located same as the old, so gas and water lines were easily plumbed. The old electrical wires could be used although lengthened to connect to the digital controls. The circulators location has changed, it's still provided with its wiring provided. Venting is the same as the old one. I was happy to get another Dunkirk that installed easily.
