Rinnai boiler

sjm4 Member Posts: 2
I am building a new home and planning on installing radiant heat throughout.  I have been quoted a Rinnai high efficiency wall-mounted gas boiler by our local supply house.  Does anyone have any experience with these boilers?

    Does it have an aluminum exchanger? That would be a negative for m.

    The HX is Stainless.

    Rinnai has a few different combis. The 75 & 110 use a plate HX for DHW. The 175c has a 6 gal indirect and the new Q85 & Q130 Premier's have a 24 gal indirect. What were you quoted?
