When we have a power outage as we often do, I can still get hot water with my gas heated tank!

The ever ongoing tank-less vs tank water heater. I am not a proponent of tank-less water heaters, however if you have to have one, do not go with the the electric models. This information was reinforced by the sales guy at a local plumbing supply shop. He "disclosed" all sorts of problems and made me be aware of them before he sold it. For instance, he says to get the unit to function on it's optimum level, it would need it's own designated power. He also says that they are more prone to "hot water sandwiches". This is what happens when there is a glitch in the system and the unit does not heat water in a consistent manner. I can go on, as to my dislikes with tankless units, however, that is not what this thread is about. The best hot water heating system you can have is a standard well insulated tank water heater with a recirculation system with the hot pipes insulated. This is what I had installed at my house and the wait time at any fixture was about a couple of seconds for hot water.

It depends on the amount of fixtures you will be using, The distance between and if you want a recirculating system that gives you hot water all over the house. Electric is fine but I've found gas is more efficient.
They are the best

Some new home builders(dallas area) use a mix on two story houses. Tank downstairs(in garage) and electric tankless upstairs. Jean214 mentioned the reliability, but I was under the impression that the tankless have warranties like the tanks do?

Consider propane of gas fired whole house water heater. Works great and you can stay in the shower for hours..:)
Also good if you have a whirlpool tub that will kill a large tank heater pretty fast!
I have had a TAKAGI for about 5 years and it is fabulous!

We had two in our house in Arizona. Loved the fact that we never ran out of hot water. The only drawback was the hot water had to be turn on full force in order to activate the units.

I installed a Bosch electric myself, 2 years ago, it was easy to do and it works just fine.
Three suggestions.
1 Know how many gpm you need
Check manufacture's specs for gpm @ 60 F degrees temp rise (approx)
2 And your intake temperature - as temperature rise gets bigger gpm gets less.
3 Know what your total cost is for 10 years for gas and electric.
Gas is in therms
Electric is 1 therm = 29.3kwh
And if your hot water tank is in a heated space, remove insulation and use it as a passive heater for the tankless - reduces temperature rise.

I don't have one in my personal home.
We almost always use them for every remodel we do. It saves space, time and money.
You can put them in the attic even, or on the outside of your home.
The brand our plumber always uses is "Nortiz"
One other thing you might want to look into, we have only installed two of these so far this year, most people don't even know they exist.
Laing Recirculating Pumps.
You put it under the farthest vanity sink from the hot water heater.
(you will need electric to operate it)
It ties in with the hot water under the sink, before it gets to the faucet, and will circulate hot water to all the fixtures in the house.
It works awesome !

Great green idea..Get a few bids..Lot of good ones on the market.
I've installed about 20 gas ones. Hot water on demand, saves energy....go with it.....

I considered one when replacing my standard water heater recently and choose the old-fashioned tank heater after a licensed electrician and two licensed plumbers told me to avoid the tankless varieties then on the mariet (October 2008.) The electrician and one of the plumbers did not sell the equipment, so they had no vested interest in my final decision. They said the tankless varieties fail often and do not bring hot water quickly to the tap where it is needed. As they cost more, the idea of installing two or three defeats the purpose if you are trying to save money.

The only drawback that I know of is that you need one for each area unless they are close. For instance we would need to put one in our kitchen and in our bathroom, and we don't have room for one in our bathroom. We had wanted to install one as well, but could not for that reason.
Does anyone have an electric tankless water heater?
