Can you connect two hot water tanks?
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.
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.
How does one water heater affect the other?
Hot water coming out of the two heaters is combined and sent on to the fixtures. If you want to turn off one of the water heaters, you also have to close the valve to the inlet or the outlet. Otherwise you will just be mixing the cold water in one water heater with the hot water from the other heater.
How is cold water split between two water heaters?
PARALLEL In parallel, the incoming cold water is split between the two water heaters. Hot water coming out of the two heaters is combined and sent on to the fixtures. If you want to turn off one of the water heaters, you also have to close the valve to the inlet or the outlet.
How does a two pilot light water heater work?
Instead of warm CO2 floating up and away it sits under the water heater until there is no longer enough oxygen to maintain the flame. With two pilot lights going there’s enough heat to the chimney that a sufficient draft can be maintained. With oxygen depleted air drafted up and away free oxygen rich air can be brought in to keep the flame burning.
Can you still use two series water heaters?
You can still use two water heaters in series and keep the second one at a lower temperature. Once the bacteria gets above 50C it will kill off any bacteria from the other tank. dandersen (David Andersen, TN HI# 40) January 15, 2015, 2:35pm

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.
