Tankless water heaters -- inneresting take.
http://www.waterheaterrescue.com/pag...r-heaters.html Now, this guy sells anodes'n'**** for tanks, but I found his take level-headed. The raw thermodynamics of tankless -- esp. gas tankless -- puts one big strike against tankless from the gitgo. -- EA |

The only points where I would disagree are where he claims it's $600 for an installed tank versus $2500 for an installed tankless and more if it's a retrofit. I can see the $2500+ for some, maybe a lot of retrofits. But for a straight swap it seems very high.

The basic, cheap conventional that he's comparing to has a flue that goes right up the middle of the hot tank. A significant amount of heat is lost via that path when the tank is just sitting there. You can reduce that path via one of the direct vent type units, but then those are significantly more money and like a tankless have more install work involved for a retrofit. I also have some doubts about the claims that manufacturers of tankless come and go. That may be true with some, but there are major manufacturers that have been around a long time, including well established companies that make both tank and tankless. |

A significant amount of heat is lost via that path when the tank is just sitting there. =============================================== But there is also a "draft break" from that stand-off ditty, so that the chimbley effect is not nearly as onerous heat-wise as without that break. But, I would still like to see a powered vent, that closes when the unit is off, opens when on. Seeing as how Sears et al bangs people for $1,000 for a "non-standard install" that takes all of one hour extra, I can only imagine the banging people get for a tankless install. I'll bet they hype a "1 year ROI" on a $3,000 installation.... You can reduce that path via one of the direct vent type units, but then those are significantly more money and like a tankless have more install work involved for a retrofit. I also have some doubts about the claims that manufacturers of tankless come and go. That may be true with some, but there are major manufacturers that have been around a long time, including well established companies that make both tank and tankless. ================================================== = No doubt there is *some* spin in the article.... lol His point about "instant on" has another piece to it. With a tank water heater, AND a recirculating pump, you can indeed have true "instant on". With tankless, I don't think this is possible -- your "on" will be obligatorily delayed by the length of the run. This could be a major issue for epicureans. I think he is def'ly right about the tankless hype, tho. I don't see too many people benefitting from a conversion to tankless, esp. utility-wise, and overall cost-to-own-wise. I'll bet that those who do like the conversion to tankless didn't have their trad'l tank system set up or sized correckly. Speaking of epicureans..... Has your bedside/ng manner been improving?? -- EA |

The originator Takagi has only been making tankless heaters for 60 years and still going stong. The other main player Rinnai has only been making tankless heaters since 1964 and is still going stong. yawn..... whatever..... Talking thermodynamics to your dumbass is f'sure pointless..... Tankless is hype. Any honest breakdown of the economics will show sig'ly higher cost-to-own for most people. Not that the technology/systems is so so bad -- still thermodynamically profligate, but in larger part, the "infrastructure" for plain ole water heaters is so large, that that in itself gives the trad'l a homefield advantage. Hey, but I know this is over yer head, and it would be a, uh, tankless task explaining it to you. And I know I'm distracting you from preparing for your single-sleeping-bag BoiScout campout with JoeBoi.... have fun..... -- EA |

Funny how tankless heaters have been around for more than 50 years in Europe and are the primary mode of providing hot water to households One has to wonder why something that has had 50+ years of daily usage in a large parts of the world would allegedly be so far back technically as the author claims. There are TWO reasons why the tankless are still expensive to buy and install: 1) They are relatively new and unknown here, with not much demand for them yet 2) They are going against what has been the norm during the 50+ years. Change is slow I should also mention that there is resistance from the plumbing establishment, who are being challenged in their "control" zones. |

A lot of the rest of the world has a lot of things going on in the economy that are not governed by free market economics, but instead by govt mandates, regulations, subsidies, etc. For one thing, the cost of energy is typically substantially higher in many places than it is here. People in those other parts of the world could just as easily point to the huge market for water heaters in the USA and how little of it is tankless as evidence that tank type is superior. Most of what is pointed out in that link is true. Particularly that the total cost of installing a tankless, particularly if it's a retrofit, skew the economics so that it's unlikely you'll ever recover the higher initial cost here in the USA, where nat gas is still relatively modest cost. There are TWO reasons why the tankless are still expensive to buy and install: 1) * *They are relatively new and unknown here, with not much demand for them yet 2) * *They are going against what has been the norm during the 50+ years. Change is slow I should also mention that there is resistance from the plumbing establishment, who are being challenged in their "control" zones. Of course the fact that in a lot of retrofit cases you have to increase the line size all the way back to the gas meter, maybe replace the gas meter too, put in new venting, etc has nothing to do with it, right? Or the fact that if the power goes out, with a tank type, you still have hot water for 2 days? |

If everybody in any area of concentrated population had an electric tankless system, they'd blackout the local grid every morning. If they all had gas tankless, the CO2 would proly make everyone so sleepy they couldn't drive to work. Plus, in gas tankless, the thermodynamics is all wrong. Well, not scientifically wrong, just energetically immoral..... -- EA |

The faucets were fifteen years old and for a high prices manufacturer like Grohe that’s considered very new. Sure you might be able to get it on E-Bay but you won’t know if you’re getting a rebuilt that’s going to start leaking in a few months. Another client had a built in Kenmore microwave oven that Sears said they no longer had the magnetron to. I can understand not having some obscure part but a magnetron? Give me a break. |

I think it had to do with the electric windows, but not sure. Anyway he could not get the part from Ford and had been around to a lot of junk yards and none were available. Now if he had a Modle T he could probably get almost anyting for it. Not from Ford, but many aftermarket places.

That’s usually because they have their balconies closed-off to make more living space and they can’t afford to have a plumber run lines to it anyway let alone have the lines enclosed so that the apartment doesn’t look like a machine room. The really funny thing is when they come to the U.S. they usually buy the same type of dinky condos that they left behind. Un-f’n-believable. |

The other main player Rinnai has only been making tankless heaters since 1964 and is still going stong. PEX has been around for many years, yet people are afraid of it. I would not use tankless on a retro fit, but certainly would on a new build. many gas tankless are power vent, no electric no hot shower. our longest outage was over 3 days, luckily it was in the summer, still a hot shower was nice...... after cutting up downed trees all day Some gas tankless units are installed on exterior walls of the home; require no power venting at all, as they are not inside the home. Love to see one of those suckers survive anywhere much north of the Mason Dixon line. |

About 10 rooms where some 13,200 volts come in and is converted to 480 volts 3 phase and other voltages. It was just where the hot water was wanted was too far away from one of the power rooms. Later some regular tank type heaters were installed as we did have some 240 volt circuits close by that could supply 20 amps. |

If you really want a POU unit or just want to move the tank, you ought to start planning it - and plumbing it - when everything is in working order. |

Did they at least total up the dollars that were wasted by the poor planning and dock the guy's pay? (Not that they ever, ever do that.) |

If you really want a POU unit or just want to move the tank, you ought to start planning it - and plumbing it - when everything is in working order. What needs to work? It's just pipe (and electricity, but that's trivial). I can see adding the new one before ripping out the old one but advanced planning? I'd rather not touch plumbing until I need to. |

Well, the main is 300A (150+150), though that's everything. The two heat pumps need a little of that. It was kinda cold today (48F). Just for the record, I was commenting on the statement "and the voltage is 220 volts in them there places". We generally have 240V available too. |

I don't see that at all. Moving the WH would be easy. It would be a trivial difference in a replacement. It would probably make it easier. |

Heck, the first tankless water heater I installed needed two 240 volt circuits run to it. ^_^ In a very large plant where I worked two tankless water heaters were installed. It was then discovered that it would cost a couple of thousand dollars to get the power to them, so they were then taken out. There is plenty of power at the plant. About 10 rooms where some 13,200 volts come in and is converted to 480 volts 3 phase and other voltages. It was just where the hot water was wanted was too far away from one of the power rooms. Later some regular tank type heaters were installed as we did have some 240 volt circuits close by that could supply 20 amps. They should have asked Joe The Plumber before proceeding. ^_^ TDD |
