Triangle Tube Vs. Lochinvar or Maybe Navien Combi?

Yes, I am looking for your opinion :-)

Looking to replace a 16 year old Laars Endurance 110 EBP (propane). Need a combi unit with DHW and heat. 2 zone raised ranch. 1 zone is baseboard, 2nd zone is hydro air handler. I do have well water but it is neutralized and softened so it should be decent.

I have heard enough mixed things about Navien to be a little concerned... although parts seem to be available anywhere you look. People seem to either love or hate them.

Triangle Tube, Lochinvar, Rinnai and Navien seem to be the most available units in my area. Any opinions? My main concern is reliability and longevity.

  • Lochinvar stands out from those you mentioned.
    Often wrong, never in doubt.

    All four of those makes are good, and none is better than the installer and the installer's understanding of how to install, pipe, and control them. They are not plug and play by any stretch.

    That said, sizing is critical, particularly with high performance modulating units -- since you can't achieve the benefits you are paying much money for it the unit is the wrong size. And this is where combis, as a group, have a problem: Sometimes one which is the right size for your heating loads is also right for the domestic hot water load. Usually not...
