NTI FTVN , HTP ELU-199WBN , or Navien NHB-110

JJohn

I reside in NJ and am looking to replace a 15-yo Munchin T-80. Approximately 3,400 sq ft house, both floors radiant heating.

I have received estimates for: (1) NTI FTVN 110k btu; (2) HTP ELU-199WBN; and (3) Navien NHB-110.

Which one is likely the most reliable? Thanks.

It's all about installer, and somewhat about parts availability. I don't personally prefer any of the brands mentioned, but they are all decent boilers that many installers trust, and can get parts for.

T80 looks like it was an 80,000 BTU input boiler. Personally I would look at an 85,000 input if it were me, however you already have 3 quotes. 2 for 110 input, likely the smallest size those brands offer, and they modulate so its close. and 1 for a 199 input model more than 2 times the input of your old equipment. I would personally ask that installer why they quoted a boiler more than twice the size of the old one, and if they could quote something a bit closer to what is there now. of the 3 HTP is probably the one I like the most but I wouldn't want an installer to double the equipment input size on me. HTP offers a few options for 85,000 input boilers

As @GGross has mentioned you probably only need a 85,000 btus for the heating load. All depends on the overall Heatloss of the house. The HTP ELU-199 is way oversized and I wouldn’t go with any Navien products.

@JJohn where in NJ are you located?
