Currently our hot water heater is located in the crawl space beneath our house. We'd like to replace it with a tankless system but are not sure where to install the unit. It would be easiest as far as plumbing and electrical to put it where the traditional hot water heater is, but is it a real option? We live in central North Carolina where temperatures are rarely less than 30 degrees during the winter months.

that will turn on the electricity when the water starts flowing. Anybody know where I can get one?
OK thanks. I guess I didn't realize they would be that easy to find.

I was wondering if I could use my home electric tankless water heater to heat the pool as well as my home? If not could I run one just for the pool?

Can anyone point out a good tutorial please?

I'm thinking of buying a tank-less hot water heater for my whole house but i've read that the natural gas heaters don't put out the flow that they advertise and it is best to go with an electric.I have a 40 gallon electric now that i bought 2 years ago.It is turned up all the way.I have never been able to take a 15 minute shower without using up all the hot water.I never had that problem with my old 40 gallon gas heater.Also my shower head plugs up with lime deposits so often that many times i cannot finish 1 shower without taking it apart and rinsing it out.The gas heater did that only 3 or 4 times a year.That makes me very reluctant to use another electric heater even a tank-less.I don't want a water softener.I am willing to put up with cleaning the shower head 3 or 4 times a year.If anyone is using a tank-less now i would like to know what brand it is,how strong it is and how happy they are with it.Thanks!
The first 4 answers seem very knowledgable but it does not sound like you are using one in your home.I need an answer from someone who is actually using one.Do you like it? What size and brand is yours? Can you take a long,hot shower? Gas or electric? What about lime deposits? Thanks!

We're on a well & the water is hard. We do have a softener. Any advice and knowledge would be appreciated. Thank you!

If I take a shower I have to run the bathroom sink faucet on its hottest setting in order to have a hot shower(the hot water will stay hot for as long as I want if I do this ) -if I dont do this the furnace will go hot for 3 minutes -cold for 3 minutes fluctuating temperatures -
the furnace works on demand for hot water and is great except for this little glitch
note when I say it is hot water on demand I mean there is no hot water tank -just pipes which run through a small 2 ft by 3 ft furnace

I just moved into a condo a few months back and was excited to have a bathtub again. The only problem is that the water heater that we have only fills the tub up with an inch or two of hot water so baths are pretty much out of the question. The spot where the current water heater is is rather tiny, it's in the kitchen in the corner under the countertop. I was wondering if a tankless water heater would be a wise investment? And by wise I really only care if I can get a decent hot bath out of it. Thanks.

We have 2 bathrooms, a washing machine, a diswasher with 2 adult living in the house.

Our electric company has a program in which they install a device on the water heater that lets them shut it off for 6 hours at a time, if necessary, during peak demand times. In exchange, they give a 2% discount on the total electric bill.

We're trying to decide if this is a wise decision, or if we'll find ourselves without hot water when we need/want it. If we agree to it, it's a minimum 1-year commitment, so we want to be pretty sure about it.

Thanks for any information!

Have a Panasonic 220V instant water heater from Thailand, that I would like to wire into my 220V US breaker. It seems Thai wiring/breakers are different from US. Thanks for your help.
The unit is 220 V 50 Hz

My propane tanks are full. The stove, oven and heater all work. When I try and light the water heater, the igniter does spark, there is flamage. but this last only about 2 to 3 seconds ( the igniter is sparking this entire time) then it shuts off. It will cycle like this for 3 times. Any ideas??
