Forrest Gump 9 Posted December 24, 2014 Report Share Posted December 24, 2014 Please school me on the tankless water heater. I'm looking to upgrade soon. Just wondering if anyone here use them? Install? Any advices/suggestions are welcome. Thank you and happy holidays Quote Link to comment Share on other sites More sharing options...
Mojoe Posted December 24, 2014 Report Share Posted December 24, 2014 http://home.howstuffworks.com/tankless-water-heater.htm Those 5 pages of reading are helpful. When I was looking at them as an option, the turning point for me was the exhaust vent and fuel use. I only want fuel as a back up. I like tankless, it just wasn't right for our set up.

Mr. Jones Posted December 24, 2014 Report Share Posted December 24, 2014 I briefly looked into one, and was told by more than 1 source that for it to be feasible to replace a large hot water heater that gets lots of use by a large family, I'd need to have have at least 200AMP service. Also, that a water filtration system would also be ideal to prevent mineral deposits from eventually ruining it. Quote Link to comment Share on other sites More sharing options...
SloSVTruck Posted December 24, 2014 Report Share Posted December 24, 2014 One of my customers I have done a lot of work for had one installed. He always got the top of the line stuff though.... I don't see these working good unless they are fed by natural gas. An all electric whole house one would be a pain and a waste of time I think. The one he had was supposed to be like 85-95% efficient with natural gas. The plumbing that had to be installed for it was a little tricky it looked like. He had a circulation pump hooked up inline and the heater would kick on and run the pump every half hour or so to keep the water constantly hot and ready. As far as I know he hasn't had any complaints about the system really. Quote Link to comment Share on other sites More sharing options...
gillbot Posted December 24, 2014 Report Share Posted December 24, 2014 I've seen "green" people put small units under sinks in tandem with a whole house or regular unit to heat the water coming in until the main tank hot reaches the tap. I've thought about putting a tankless in myself but just can't justify the cost. Quote Link to comment Share on other sites More sharing options...
spectragod Posted December 24, 2014 Report Share Posted December 24, 2014 I have a tankless heater, endless showers are great, but you have to do your homework.... First, if you have a long run for exhaust, triple wall stainless vent pipe was $60 or so a 3 foot section, your tankless heater will require a dedicated exhaust, meaning you cannot tie it into existing hardware. Said heater will require a feed from 1" hardline, no less and no flex pipe. I used a bosch unit, it uses regular galvanized exhaust, which saved me about $900. The rest was easy, fwiw, you won't save anything on gas or water, but I did get a bunch of space back as my weather heater was in a closet.

Mojoe Posted December 24, 2014 Report Share Posted December 24, 2014 (edited) There is also some info out there about if you are on a well and have hard water, even with a good softener, the life of the tankless system can be short.

Coaster Posted December 24, 2014 Report Share Posted December 24, 2014 I looked into them. I got scared off by parts availability and the need for constant cleaning needed with our hard water. Quote Link to comment Share on other sites More sharing options...
Turbs3000 Posted December 24, 2014 Report Share Posted December 24, 2014 We almost installed one in our current house but decided to hold off til our next and larger home. As many have mentioned the install is what many people forget about and the need for ss most of the time. I would encourage looking for one that can be horizontally vented. The one we had could and it meant we could install it right to the basement wall and vent it right outside and be done rather then redoing the venting up to the roof. it was also NG and would have been on Columbus city water for what that's worth.

macpyro2 Posted December 25, 2014 Report Share Posted December 25, 2014 I install them frequently. Pm me for questions, when I get time I will write something up here. I see some outdated info being shared though. Quote Link to comment Share on other sites More sharing options...
Dave1647545494 Posted December 26, 2014 Report Share Posted December 26, 2014 Tankless stuff is pretty reasonable anymore. You need to size it appropriately for your home. Whether your on gas or electric whatever service you have at your hot water tank is normally good enough to hookup the tankless. Quote Link to comment Share on other sites More sharing options...
