Tankless hot water heaters???
Time has come to replace the hot water heating. I am thinking going tankless. The one we have now is electric and would like to stick with that. An advice.

Buy electric one. Don 0 -
Lots of questions to ask . What is your projected usage rate ? How many folks looking to shower every morning etc . Several folks here have them if memory serves correctly . I am sure they will be along soon

i asked the same question a while back when replacing mine. Problem with the electric, is what is your incoming water temp. Mine is maybe 50° summer, upper 30's/40's Winter. Spring fed gravity cistern. Reading the info on the electric tankless site, they recommend an incomming temp of around 70°ish or so. Would not work for me. I would need a gas fired unit. It is just me here, and I am very frugal on water, but the temp. Differences were what made it unworkable for me.
If not for that, I would have gone that route.
Do some research. There are some knowledgable plumber types here that will weigh in. Oakie, etc.

I don't know why, but I've heard the gas option is better. We LOVE ours....it paid for itself the first year. Our power bill went down noticeably when we went tankless. Not one problem in the several years we have had it.....non stop hot water all the time. 0 -
Electric tankless is not good. I can't think of a more politic way to say that, but I can think of much worse. Gas tankless is great. We're on our second one (the first company went out of business and no parts available, but it worked just fine until it blew what ought to have been a fifty-cent gasket.) Ours saves us a grundle, provides limitless hot water, does not need flushing, and saves enougn room that we could put in a softener system as well. 0 -
You going to do install, or hire it out?? Recommend Harvey's. Ask for Justin. 0 -
if possible go with gas, 1/2 the operating cost. I've got a takagi, 12 years old and no issues. spend the $$ once, not forever 0 -
Your electric service may not be adequate. Rule of thumb- twice the amperage of a tank type heater. 0 -
I am on a well. I got the Rennai put in 4 years ago. In a week it was clogged up with sediment. Well company had to come out and clean it. A week later, it clogged again. I have a whole house filter and my tap water is crystal clear, and tastes great.
They said I had to put on a super duper ultra fine mesh filter. Well I figured I would be down there once a week to clean out the whole house filter. So I told them to replace it. They installed a tank water heater like we had before.
My brother is on a well and he has the Rennai and he likes it. These are all gas appliances.0 -
Why would you heat hot water? 0 -
We have a propane fired Navien tank-less system. Very hi-tech so you wont be doing any self servicing. Our water was in the middle of being soft/hard so it was recommended that we put is a softener. Otherwise the calcium & other minerals would build-up & cause it to fail. The build-up in our steam humidifier was so bad I had to clean it every year. Besides the softener, that's on the reverse osmosis system. 0 -
one needs all the kitchen faucets and bathroom sinks tub/shower as close as possible to the tankless or you always have a run of cold water before it gets hot.....lake place is close, no more than 10' to all so not to bad but home is a lot longer distance .....or spending all your time in one house you need a temp controlled recirculating setup on the hot water side so there is always hot going by the faucet if you want instant hot....???? 0 -
You have an extra three slots in breaker box? electric Tankless hw heaters use like huge amounts of current and I dont recommend them, stick to gas if going tankless. 0 -
spasmcreek what you say is true, but it's true for all kinds of water heaters, not just tankless. There will always be what they call "pipe lag" during which you have to run out the now-cooled water between the faucet and the heater. Some "tankless" heaters actually have a small - like one gallon - reservoir that it keeps hot to minimize the delay in heating incoming cold water, but you still have to run out what is in the pipes downstream of the heater before you feel hot water. 0
