Other builder says he thinks chimney has to stay even if I go to HE water heater.
Makes a big difference in what we can do with remodel floor plan
Who is right?
AFAIK, there is no HE electric water heater, so, you must be asking = about a gas fired HE. I have one like this and all it needs is a PVC = (?) pipe to the outside and a fan on the outlet.
I closed off my furnace flue when I redid the shingles.

many but not all dont require a chimney.
do realize the thru the wall vent type dont heat in a power failure.you would need to add a big UPS. the hot water in the tank will remain hot till used but in a power faiure it wouldnt be replaced.
getting rid of the chimney is a good idea, elminates maintence on chimney and in cold climates does away with that BIG heat loss of the chimney drawing heated basement air out 24 / 7
Were planning on a new 90+ furnace and high efficency hot water tank with thru the wall vent hopefully this summer
The manufacturer's recommendations trump the builder. What do they say on the installation instructions?
Are you daft? Or just a troll?
You provide no information to help you.
As far as I am concerned your next post like this will get you to the block sender file.
There are two types--direct vent and power vent. The former, as its name suggests, vents directly to the outside via PVC pipe. There may or may not be a fan at the outlet. The distance from the water heater to the output is limited, usually not more than 4-6 feet, depending on local code. The latter type uses a fan mounted on top of the water heater, and also vents to the outside via PVC pipe. With power vent the run can be longer, but is also dictated by local code. There are also restrictions for both types as to where the vent is located. Where I live, in SE Wisconsin, it must be no closer than 4 feet from a window or door, for example. I don't see why you should be required to vent into a chimney.
I have a Ruud "direct vent" 50 gallon water heater which takes in inlet air and vents exhaust directly thru the wall and requires no electrical power for operation. This type has to be located within about 18" of an outside wall.

Wow, you are a bit cranky.. 5 of 6 responders to my question were able to cull enough data out of my post to give thoughtful, and helpful answers. (it was a simple question really... do the make hot water heaters (implied gas) that operate without chimneys.) Thanks to them for the answer.. as to you, go take a nap... maybe you'll feel better in with some sleep..... Geeeeez
Oh, sorry.. didn't answer your questions:
Yes, in fact I am bit daft... sort of "pleasantly demented"
No, I am not a Troll, although I know a guy named "troll" he is the athletic trainer down at the high school... very good guy.
If you are using the original chimney that a gas furnace was disconnected from, then you absolutely MUST get a high efficiency gas water heater vented through the wall AS SOON AS POSSIBLE. If you read the furnace installation instructions, it should warn you about the possibility of your chimney falling apart. This is because now you don't have enough heat to keep it dry.
while were at it a good source for high efficency tanks please////
a good friends tank is on the way out and nothing at home depot appeared real high efficency
by chimney I mean a metal tube running up & out the roof... not a masonary one. Would something like this be an issue with a metal "chimney" Maybe I am using the incorrect word, maybe a chimney is only supposed to be masonary... but this is in fact metal insulated ducting.
They're commonly called a metal chimney or flue. A masonry chimney can fall apart if it isn't kept dry. An approved metal chimney should not fall apart, but there is a strong possibility of not having enough draft when a metal chimney is much larger than the water heater's vent pipe. Has anyone experienced headaches or been light-headed since the old furnace was disconnected?
Bradford White "Through-the-wall gas water heater" is one brand name. There are two in my recently-built house one up and one down to minimize hot water waste though pipe runs. Both have worked without problems for 3+ years now and both have forced air vents through the house walls. One has an exhaust run of about 20 feet. The "Energy Guide" sticker that came on the heater says it uses 238 therms a year from a range of similar heaters that use from
220 to 288 therms/yr. They use house air and would be more efficient if they drew outside air; but I couldn't find a model that was designed for that at the time.TKM
