The fact is, the Takagi units are by far the best made, with the best materials, with high-end copper heat exchangers, and they can take anything. They do not break, they just work work work without a problem. Just make sure the filter is cleaned, and you will be happy. If you have hard water, get a softener electronic do-dad that goes around the pipe, and you won't even have to do the yearly scale cleaning.
For all those brochures that tell you, you need a professional installation, well, you don't. It's the easiest thing ever, and a patient handyman with a good "how to do plumbing projects" background can handle it. Especially for the outside units. They are literally installed like this: Screw it on the wall, screw the pipes on, screw the electrical cord on and you are done. Works like a charm.
All you really must have is a properly sized gas line of 3/4" so you get the full but capability and fpm flow. And you need to pressure test your line no matter how large it is, to make sure you're getting enough gas pressure. Often a has line runs too far away from the source to keep the press high enough, so go online and look up the math problem first, figure out how long your gas line can be, and do that. In general, you need to be only about 50 feet of pipe away from the your gas meter. That's generally. If you are 75 feet away, you might need a 1" or 1 1/4" pipe. That's the only trick that I've seen can mess this up.
Otherwise it's fool proof.
I do recommend one upgrade to make this look really slick and professional. It's a LOT more work, carpentry-wise, but if you are installing an outside unit, think about using the recess box. It's about $175 more, but it looks so sleek and finished when you're done, and it also protects the unit from the elements and rom tampering. It fits right inside the wall between most wall joints. Look up photos on line and judge for yourself.
On the other hand, if you are smart, you are installing this thing in an out of the way place that isn't very visible anyway, so just slapping it on the side of the house is ok too.
Assuming you have a good gas line, you can install these outside units in less than half a day. And don't be afraid of attempting to install a new gas line either--it's just a lot of pipe pieces cut to fit with lots of goop at the joints. If you can tighten a goopy joint, you will be fine. Just make sure to put a pressure tester on the ends, pump it full of air for 24 hours, and make sure the pressure needles do not budge to make sure your fittings are screwed tight.
Everybody gets scared of doing gas projects, and that's why they don't go with tankless heaters--most licensed pro's charge $1500 to $3000 to install them. And it's totally worth that, if you do not want to do it yourself, or you think it's above your skill level. I'm just here to say that if you are patient and very handy anyway this is a real no brainer project if you just follow the steps.
Finally, to all the naysayers who make a decision about tankless or tank hot water heaters based on money, I say they're full of head feathers. It's a no brainer: Every human being on the planet wants to take showers, do dishes, take baths, and never ever ever ever ever run out of hot water. Only an idiot would be willing to run out of hot water several times a year just so they could save money. Everybody with a tank knows what it's like to run out of hot water, and it's awful. If you have somewhere to go, you'd pay almost anything to be able to shower right then.
Add to that the savings to Mother Earth, by using less energy, or getting that basement space or garage space or closet space back--these go outside, remember--it's really an easy decision to go with these.
You can make phone calls on a flip phone too, but once you use a smart phone, you don't go back. You can drive a regular gas guzzler, but once you drive a hybrid, you don't want to go back. Tankless technology is like that too. Once you enjoy endless hot water and the ability to touch a little computer pad and change the temperature on the spot, you just won't ever go back to the old way.
