Combi Boiler/Water Heater choices
I've been doing quite a bit of research on these boards and am very thankful for the information that it has give me. I'm a laymen, though not entirely. I think I'm knowledgeable but in reality I'm a first time home buyer so i only know that i don't know anything.
Here's my predicament. the home we bought is a 2800 sqft 3 full bathroom, two heating zone house with brand new high efficiency appliances (re: water use). I have a wife, a 2.5 y/o boy and a girl on the way, so that will give you an idea of present and future load.
Are utility room is a small space that was made smaller when a shower was put in in the adjoining bathroom, so all the plumbing, water heater (over 15 y/o) and boiler (32 y/o) are shoved into a corner with the pipes all out of whack and the boiler darting out into the door almost. I want to make space there for being able to move around and actually have room to do laundry... so combination unit is pretty much my only way into saving space and redoing that room.
I have three quotes on the floor... and while i know we don't talk prices here, they range from under 10k for a Navien CH-240ASME, a Prestige Trimax Excellence for a few over 10k, and a Rinnai Q175 CN for over 15k.
My biggest issue is not having enough water around, money isn't really the issue but a factor of course, space saving is an issue but all the combi choices save space... In terms of water, the GPM for Navien is 4.5 at 77 degree rise, TT is only about 3 at 70 degree, Rinnai is 4.1 at 75 degrees.
I know from this board that Navien isn't a favorite at all, the TT seems to offer not enough GPM for my family though it's favored here, and the Rinnai is just hugely expensive. All quotes are from very reputable and experienced installers whom have experience with these particular models.
I just dont know what to do, but i want to do it right and do it once... i don't want to wind up in the winter with not enough hot water and cold baseboards... I've considered a standby as an addition to this, but i may not have room. So one unit would really be ideal.
Any help would be greatly greatly appreciated. I live in NJ.
