i live and maintain apartments in SoCal. have to replace a water heater and want to go tankless. any help appreciated

This was custom build as a xmas present for a small off-grid home that has no power to spare and no water pressure. It is a prototype so could easily look much better. It could easily be adapted for camping or as a permanent setup in a cabin or off-grid home and would work and look even better. For details about construction, the parts required, and more, visit www.techienation.com . There will be details there shortly.

I am replacing a gas water heater that is 12 years old. It’s time to replace it. I see that there are tankless water heaters out there now. My questions are as follows:

1) Is tankless water heater technology mature?

2) How does a tankless water heater work to supply hot water for a shower or filling a bathtub? In such a scenario, cold water (possibly 35-50F) must be heated very quickly by a hundred degrees or more in real time in order to supply hot water fast enough. How does such a water heater accomplish this?

3) My specific needs are for a shower or two at a time, lasting in total 10-20 minutes, and then intermittent daily use in faucets and the like. Would a tankless fill needs?

4) Any specific brands to seek out/avoid?

Thanks.

I am building a house and purchased a Rinnai 2532W LP outdoor tankless water heater. Can I install this model in my garage without venting it?
I am building a house and purchased a Rinnai 2532W LP outdoor tankless water heater. Can I install this model in my garage without venting it? What is the danger if I don’t vent it? I don’t live in the garage after all?
I also have a set of White Mountain Hearth ventless gas logs. I suppose those need to be vented as well?!

I’m seriously considering purchasing one of these soon and I see that both licensed plumbers and heating and cooling pros offer installation.

I wanted to know whom should I lean towards (even if it may cost more) and what type of questions should I ask in order to ensure I get a real pro?

When we turn the hot water on the pilot never lites up. NOW we have no hot water.
The pilot is used to turn on automatic every time u turned on the hot water and now it is not turning on at all.

1. How do you vent a tankless gas water heater. I dont want to go through my ceiling if I dont have to my house is 2 to 3 stories. I would rather run it out of my basement window or wall like a dryer vent.
2. If I bought an electric one how many volts or watts would my panel need to be able to handle?
3. Where is a good place to study the tankless water heater with pictures and so forth of its mechanics?

I envision a future where homes are built with whichever sustainable energy option is right for it’s particular area. We all know that going green with solar, wind, geothermal, sub-radient floors, tankless water heaters, solar water heaters, micro hydro, or whatever method is high dollar to ADD to a home. How about if the home came with a solar roof. You never had to pay for the conventional roof, or it’s removal/alteration? The same goes for all the other energy items I mentioned. Not all are right for every area, but builders could determine which were right for an area, and build homes with these things in them. Wouldn’t this drastically reduce the cost of any re-fit, or add-ons? Having subradient floors be the original floor installed would seriously reduce costs. Having a tankless water be installed vs. a conventional in the first place. Is anyone building homes which require little to no energy from electric & gas companies? Without seriously overinflating the cost?

My gas water heater is broken, and I was looking at new ones when I saw the energy efficient ones. Could I replace the gas one with an electric one? The web page mentioned that they can replace the regular electric ones, but nothing was mentioned in the way of a gas heater. Any information you could give would be helpful, thank you.

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

The old, rusted tank heater that’s seen better days is mine. I never knew how bad it looked, until I lit it for videotaping. As always, thanks for watching. – - – - – - – - – - – - – - – - – Some additional verbage for those with a passion for the obvious. Now that natural gas prices and propane prices have shot up, the hot story for consumers is the tankless water heaters. If you are considering purchasing a new water heater, you should consider the tankless models. Sure most people wait for the old one to go-out before they drive down to Home Depot or Lowes to shop for a water heater, but you could begin saving money immediately with these new heaters. Conventional water heaters must heat water on standby before the water is even used. Tankless water heaters do not have a storage or standby tank, so the water is heated only when you turn the spigot. According to industry experts, you can save 10% to 20% on your gas bills by switching to tankless water heaters. You will also save on space …

I just moved into the house about 3 months ago and for my first month living here I bought a tankless water heater and replaced my regular gas heater because the tankless takes up less space. I have it mounted on the outside. I paid a plumber to install it. It is a rheem water heater. For the past 3 months my bills have ranged from 300-400 in just gas alone. I had the gas company come out and I dont have a leak and the meter isnt running constantly. It only runs when I use the gas in the house. I dont have a kitchen yet installed so I don’t use a stove. I havent turned on my ac/heat for the past 2 months so the only hting that could be using the gas is when I take a shower which is a 5 min shower daily. It’s just me in the house. So why is my bill so high?? I am so concerned b/c I paid for the water heater got it installed and now it is costing me a lot of money. I checked to see what the previous owner used to pay in gas bills and it was way less than what I am paying and she used the regular hot water tank (not tankless). I threw out the old tank which uses a lot less BTU’s than the tankless. I think the tankless uses 180k BTU’s and I had a 40 gallon tank. I don’t know what to do. And my plumber also checked for gas leaks and I don’t have any.

i have 3/4 inch piping about 40 feet from meter. also on gas are furnace and dryer. neither of which are used that often. Currently i have a 50 gallon tank water heater but want to go to tankless because it does not give me enough hot water for my japanese soaking tub.
