Question: Would this unit be able to support a 4 bedroom three bath home?
Document: Great product. Only 4 stars because unit I received had 2 blown fuses. If not it would have been 5 stars. Install was not as easy and will take an experienced contractor to put in.
The tankless units I considered all require 3/4&#34; lines (not just fittings). Talk with a plumber to make sure your meter and regulator can handle the requirements of all your gas appliances.4) Consider the maintenance&#8212;annual treatment to reduce mineral/scale build-up.5) The warranty requires installation by a certified plumber&#8212;not inexpensive.6) This unit cannot be installed under a porch or in an exterior, well-ventilated closet.
the factory temperature setting of 120 is fine for us. whe have a really big bathtub and you get it started on the temp you like and the temp does not change till it is full. the giant 50 gallon that was in here before would have been out of water by the time the tub is full. niiiiiiiiiccccccccccccceeeeeeeeeeif i was rich i would have got the condensing model which they say is more efficient.overall i am digging it. hopefully it will last a long time
We wanted to switch from electric to a natural gas tankless hot water heater and the same dealio with the stove. As for the installation, this past May, my guy did not have any issues installing the unit on the back of our house. We ended up with additional coveted pantry space and the heater has worked great up to this point.
So, obviously the big question is whether this water heater is better than a traditional storage tank. The short answer is, "Definitely. "The biggest benefit to a tankless water heater is the endless supply of hot water, and this unit really delivers. For about the same priceas an efficient tank heater, you can have this unit which heats water on-demand.
our tiny new house had a giant water heater in the laundry room taking up way too much space. i changed it out for this one and could not be happier. saved a good chunk of valuable space. was pretty easy to install too. (make sure you have a large enough gas supply line, won't hurt to oversize). because of the low NOx emmisions you are more , there are less restrictions to where you can place the unit outside.
They provide a way to isolate the unit from the system, for maintenance or repair, as well as adding service ports for flushing the heater with vinegar to remove mineral build-up on the heat exchanger.Although, the cost of a tankless installation has dropped within range of a good quality storage tank, it is still more expensive to do so.However, the luxury of endless hot water may warrant the expenditure -- it did for us.
This rating on 7 Jan 2014 is based on the machine&#8217;s performance during 3 winter weeks in the southeast U.S. I love it, but have yet to push its potential. Due to the age and build of our house, we ran into several snags during the installation&#8212;consider a few things before purchasing a tankless water heater:1) &#8220;On demand&#8221; does not mean instantly available from the tap.
It doesn't work, water shoots out from all over, I'm a builder and I just got my final city inspection and now finding out it doesn't work and it was 800 dollars, and u don't back up what usell because its past 30 days. When it's impossible for me to try it prior to final inspection. Seems like a scam to me.
However, I am getting *hot* water that stays *hot* and in my case, the installation headaches were necessary evils.
