I have been looking into brands of Gas tank-less water heater that are condensing, But still unsure of what brand to buy. Looking at the Japanese Brands that are big over hear, Rinnai, Noritz, Navien, or takagi, I will probably get two and link them, even if small house. I want to be able to run shower,dishwasher, sink, steam washer and steam dryer at same time. Anyone know what brand would be really good, I’m looking for warranty with excellent quality for long time 15+ years.
I’m also considering the water issues in the area and probably have to have a whole house water filter system installed as well as hot water filters on tank-less heaters.
I Plan to use Two Tank-less water heaters linked together for my demand.

Seeking as much information from as many to judge next move, please.would love to hear.from people with tankless systems

one of those new hot water heaters that only come on when you are using water??? I live in a trailer in a cold climate and my propane bill is horribly high as the heater is always running (gas) to keep water hot. The water heater is on an outside wall which has to be the stupidest design going. thank you . I know one name for the heater I mean is Rinnai…. some one else told me they now have less expensive ones that work the same way. thank you for any opinions or answers.

continuously for a few hours at night. What is the problem?

If you don’t laugh out loud after you read this you are in a coma!

Next time you have a bad day at work, think of this poor guy.

(Rob is a commercial saturation diver for Global Divers in Louisiana.
He performs underwater repairs on offshore drilling rigs. Below is an e-mail he sent to his sister. She then sent it to radio station 103.2 FM in Ft. Wayne, Indiana, which was sponsoring a "worst job experience" contest. Needless to say, she won.)

"Hi Sue, Just another note from your bottom-dwelling brother. Last week I had a bad day at the office. I know you’ve been feeling down lately at work, so I thought I would share my dilemma with you to make you realize it’s not so bad after all.

"Before I can tell you what happened to me, I first must bore you with a few technicalities of my job. As you know, my office lies at the bottom of the sea. I wear a suit to the office. It’s a wetsuit.

This time of year the water is quite cool. So what we do to keep warm is this: We have a diesel powered industrial water heater. This ,000 piece of equipment sucks the water out of the sea. It heats it to a delightful temperature. It then pumps it down to the diver through a garden hose, which is taped to the air hose. Now this sounds like a darn good plan, and I’ve used it several times with no complaints.

What I do, when I get to the bottom and start working, is take the hose and stuff it down the back of my wetsuit. This floods my whole suit with warm water. It’s like working in a Jacuzzi.

Everything was going well until all of a sudden, my butt started to itch. So, of course, I scratched it. This only made things worse. Within a few seconds my butt started to burn. I pulled the hose out from my back, but the damage was done.

In agony I realized what had happened.

"The hot water machine had sucked up a jellyfish and pumped it into my suit. Now, since I don’t have any hair on my back, the jellyfish couldn’t stick to it. However, the crack of my butt was not as fortunate. When I scratched what I thought was an itch, I was actually grinding the jellyfish into the crack of my butt. I informed the dive
supervisor of my dilemma over the communicator.

"His instructions were unclear due to the fact that he, along with five other divers, were all laughing hysterically. Needless to say I aborted the dive.

I was instructed to make three agonizing in-water decompression stops totaling thirty-five minutes before I could reach the surface to begin my chamber dry decompression.

When I arrived at the surface, I was wearing nothing but my brass helmet. As I climbed out of the water, the medic, with tears of laughter running down his face, handed me a tube of cream and told me to rub it on my butt as soon as I got in the chamber.

The cream put the fire out, but I couldn’t poop for two days because my butt was swollen shut.

So, next time you’re having a bad day at work,
think about how much worse it would be if you had a jellyfish shoved up your butt.

"Now repeat to yourself, "I love my job, I love my job, I love job."

"And whenever you have a bad day, ask yourself: is this a "jellyfish bad" day?"

Someone turned it off on me today right when I was going to sleep D: I didn’t want to touch it and everyone was already asleep. How do you turn it on safely? Is there something I can follow?

largest commercial heater 200 gallons?

My Bosch Tankless Water Heater has been making a noise similar to a car alarm for the past 6hrs. Not sure what caused it and can’t seem to find anything online. Any ideas?

There’s an alarm (sounds like a distant burglar alarm) coming from my (gas) tankless hot water heater (Bosch Aquastar)…

Called the gas company, but with no gas smell, they won’t do anything. Been googling and reading the manual on the company website, but no answers…

Interestingly, the alarm finally shut off this morning after 5 hours, at the same time as the furnace came on with heat….

When I turn on my hot water, it sounds like a plan taking off. Except for that, I love it.
