Connecting Water Heaters in Series

Which is the better or more efficient method of hooking up two identical water heaters? AND WHY??? 2. If I have a parallel piping job on two. Parallel is where the cold supply has a tee which feeds each water heater independently and joins them back together to one hot water supply. THANKS FOR. the power by four so you end up with two watt elements. > > VD. i would bet the pipes are in serial, not the electrical system. doing it your way would mean the water would almost never got above warm. unk @pokiesclub.club, 3/14/ 11 PM, Re: How would you set up two Two water heaters, Series option #2 2 separate hot water lines for different parts of house. Purpose: Twice as much hot water available. Turn up water heater . However, in a series system, if Timer is used on heater #1, or heater #1 is turned off except when demand requires more hot water, then best recirculating plan is.

I have two questions, one theoretical and one practical: Which is the better or more efficient method of hooking up two identical water heaters? If I have a parallel piping job on two water heaters and I have to replace one of them and the new one please click for source taller and has fresh new heat traps, won't that effect the balance?

Should I pipe those in series? Series is where the cold water goes into one water heater then through the second water heater. Parallel is where the cold supply has a tee which feeds Best Way To Hook Up 2 Hot Water Heaters water heater independently and joins them back together to one hot water supply.

Broox, What about installing a small tankless unit before the old tank? You'd see significant energy savings vs. Parallel is my preference. If both heaters are piped equal then water is drawn from them equally. A small tankless is a bad idea in my opinion. If you go that route you may as well go with one sized for the application.

If piped parallel, then if one leaks you can valve it off at still have the other work. In series this is not so, unless you pipe in a bypass and again you should've piped parallel. Last edited by Work4living; at Originally Posted by Work4living.

Curls, I own a Bosch h tankless water heater. It does require significantly more gas flow Best Way To Hook Up 2 Hot Water Heaters your normal tank water heater, therefor larger pipe, double wall flue The unit itself is quite compact though, and that can be a big benefit. My biggest complaint is the "warm up time". You'll run a significant amount of cold water through the heat exchanger before the fire kicks, and even then, you'll continue to wait while it heats up before you'll see hot water at the faucet.

Additionally, unlike a tank wh, the water in the lines won't be kept warm by the hot tank that they're connected to. So, the water comes out quite cold for quite a while before it gets warm, then eventually hot. Even if you turn off the hot water, then back on, you'll get hot, click here by cold, by warm and then eventually hot again.

The cold outside temps definitely has a significant impact on the performance.

Takes longer to heat, and not as hot once heated. And I do love that I can run back to back hot showers without worrying about ever running out of hot water. I guess it's a personal decision, but I hope this helps!

View The Engineer's Album. Parrallel is the way to go for two water heaters In series, one heater will be doing most of the work heating the water, while the 2nd one is acting like a storage tank only firing to maintain temperature under no flow. If you want to increase storage capacity, it would be better to just install a storage tank with a circulator tied back into the single water heater to maintain the hot water temperature in the storage tank. Adding a 2nd water heater to do what a storage tank could do, would be more work with gas and flues that you need to do.

If you really want two water heaters, install them in parrallel with equal lengths of pipe between the cold tee and here hot tee, or in a "first in, last out" configuration and you will have a reliable system that uses both heaters equally.

So more people say parallel, but what about question 2. Remember- one of these water heaters is seven years old and one of them is brand new-Does that change the answer?? Tha water heaters are electric. Broox, It reinforces my answer. In parallel one can be replaced while the other still works.

Tankless is not the answer unless you take the full leap. Otherwise you're wasting your time and money. I appreciate Nick's thought about a tankless for preheat but is a waste of money and energy.

Installing Multiple Water Heaters

I do this stuff all the time it is my profession. Series is an inexpensive way to plumb 2 heaters. Engineer is right with his post. I bounce back and forth between how I like to hook them up I also like to do a little extra work if I do hook them in series I feel that you are thinking of the wrong thing when talking about the age of the water heater I would guess that 9 out of 10 old water heaters we replace are from leaks not from the Heating elements failing Of course this is only a guess I never really counted it and am not sure where I could find this statistic So here is what I would look at.

What do you need the Hot water for? In the First Scenario I would do it in Parallel Water will be drawn off of both water heaters so you will get about 80 gallons of hot water out of 2 50 gallon water heaters the would still be Hot hopefully.

Now Scenario 2- I would do series but I would use the first tank as a warming tank in other words as the second water heater uses the Hot water it will pull in the water that is pre-heated from the first tank so it will take less time to heat up between showers.

In my House I have a Water alarm that also shuts off the water in the event of a leak I highly recommend them. I have seen it save a Finished basement When the tank ruptured when the person was away. To get it to pass inspection I removed the Handle from the hot side valve. Broox, Even if you look at your 2nd scenario. If piped properly and you leave room in the vertical drops to the heaters, for varied heights of different heaters.

However, in a series system, if Timer is used on heater 1, or heater 1 is turned off except when demand requires more hot water, then best recirculating plan is direct return line that goes into drain valve port on heater 2 and does not enter both water heaters on the common cold water line.

You can still make parallel work just fine. Also as you can see everyone has their own opinions. There isn't a right or wrong. All I can tell you is what I have seen, and encountered. Both ways work, source both have their drawbacks.

It's truly a matter of personal preference. I like the single tank with an added storage tank in series the best. Parallel would be great if you could assure equal draw from the tanks but I do not believe you will get that in the real life situation. The tanks also need to be of equal capacity or you will start using tempered water as soon as the smaller tank starts running out of hot water.

Just not a realistic solution IMO without a lot of electrical controls to assure equal flow from both and to shut down one or the other if it starts running out of hot water. So, since I don't know where to buy a storage tank, I would simply use 2 heaters in series and since I don't want to hook up a circulating pump as you would need when using a storage tank and a heater in series, I would simply hook up both heaters and be done with it.

I'm in NC, but I was just wondering what state you were in. But if there is some reason not to do it I want to know.
