Can two water heaters in series?
If tanks are different size or types and are not identical to each other, then connecting in series, or cold into both heaters (as shown above) are best choices. This means a 50 gallon gas and 30 gallon electric, or two different size gas, or 2 different size electric can be plumbed together without problem.
Can you connect water heaters in series?
When installing water heaters in series, the heater with the largest input (BTU or KW) should be the first heater in the series, at the cold-water inlet side of the system. Series installation draws hot water from one tank at a time. As hot water is drawn, it is taken from the last heater in the series.
Can you run two water heaters one breaker?
No. Unless for some reason the circuit for the first water heater was way over sized. If you read the manufacturer’s installation instructions for the heater, it should specify what size circuit is required. That size is for a single unit, and cannot have any other loads on it.
Are water heater elements wired in series or parallel?
Remember, in parallel, each heater has the same voltage, but in series, each heater has the same current. Basically, you only wire in series when you have two heaters of equal wattage and voltage. In most other cases, you wire in parallel.
How do you wire two heaters together?
You must wire heaters in parallel, not series when using them with one thermostat. All heaters must be wired in parallel. You can either do that by connecting each heater to the thermostat directly, or by connecting each heater to the next — just be sure that each heater is connected to the source wires.
What’s the best way to hook up two water heaters?
First, there are two ways to hook up two water heaters: series and parallel. In series, the water comes in to the first water heater, then passes through the second hot water heater, and finally goes to your fixtures.
Why are dual water heaters plumbed in series?
“That the two water heaters could be plumbed in series to improve efficiency. (one tank set low, like 25c, the other set to 56c). He said that they would have been plumbed in series by the builder, and he’s wasn’t not sure why these ones are in parallel.
What’s the difference between parallel and series water heaters?
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 each water heater independently and joins them back together to one hot water supply.
Do you have to use tempered water in a dual water heater?
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.
How to install a second additional water heater in series?
Dual water heaters installed in series. That is how mine is hooked up. [you can also do it in a way called parallel, but that will be a different video] It’s fairly simple once you see it. First you will need the space. That alone will end this project for many people. But if you have the room, its not too hard.

Can a water heater be connected in parallel?
Equipment being equal, two or more heaters connected in parallel will deliver more hot water than the same heaters connected in series. In a parallel configuration, the hot water demand is taken equally from each unit.
Can you connect two tankless water heaters together?
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 each water heater independently and joins them back together to one hot water supply. Do I need one or two tankless water heaters?
