Water heater wiring diagrams are a very important document for anyone who is looking to install a water heater in their home. This document will have all the information needed to run hot water through pipes and radiators throughout the house or other structure. The water heater wiring diagram is what makes it possible for the water heater to operate as desired. A water heater can appear intimidating, but they’re actually quite simple devices that heat water using electricity and then store it until it’s needed. There are two main types of water heaters: tankless, which heats up hot water on demand, and storage, which stores hot water in a tank until you need it. Let’s take a look at some helpful tips when installing your own home or commercial property!

Before You Begin
Before you start any water heater wiring installation, be sure you have all of your parts and tools on hand. If you are doing an electrical wiring job, make sure you have your electrical permit. If you’re plumbing, you’ll need a plumbing permit. If you are installing a gas water heater, you will need a gas permit. A water heater wiring installation is a big job, so don’t try to do it all in one day. Make sure you have plenty of time to allow for re-dos, mistakes, and unexpected snags. If possible, leave the water turned off to the area where you’ll be working.
Know the basics of water heater installation
- A water heater uses electricity to heat water. The water heater is powered by a circuit breaker or a specialized thermostat.
- Hot water is fed to radiators and/or faucets through a pipe system. A water heater has two connections: an inlet (where water enters the pipe system), and an outlet (where water leaves the pipe system).
- A water heater sits on a slab or floor; it is not attached to the wall. They must be level and plumbed so water flows freely out of the drain.
Know the location you’ll be installing your water heater
If you’re installing a new water heater, you’ll want to place it where it’s easily accessible. You’ll also want to make sure it’s placed at least one foot away from any wall. You may need to hire a professional to help you get the water heater installed correctly. If you’re working with an existing water heater, you’ll need to know the size of the unit you’re replacing so you can find the right replacement. You’ll also need to locate your water heater near a cold water supply, an electrical outlet, and an outgoing drain pipe.
Consider installing a humidifier or venting tank
A humidifier is used with a water heater to make sure there’s enough steam in the air. It makes sure your water heater isn’t drying out your home. A venting tank is used to distribute the water evenly throughout the house. It also keeps your hot water heater from overheating.
Get your wiring and inputs sorted before the install
The first step to wiring any sort of water heater is to trace the input and output wires. This may seem like a confusing concept, but it’s actually quite simple! First, turn off the breaker that supplies power to the water heater. Next, open up the water heater, and disconnect the input and output wires. Now, trace the wires back to the breaker box. Once you’ve traced each wire, write down the color of the wire and the name of each connection. This will make it much easier to connect everything up when you’re ready to install the water heater.
Installing a Tankless Water Heater
- Turn off the electricity: Make sure you turn off the electricity to the area where you’ll be working on the water heater.
- Install the water heater: Place the water heater in the desired location. Make sure it’s level and plumb.
- Connect the water heater to an electrical outlet: If you’re installing a gas water heater, you’ll need to have your gas permit. Make sure the gas line is installed properly.
- Connect the water heater to the water supply: Make sure the water supply line is connected to the water heater.
- Install the drain line: The drain line is usually a special plumbing fitting: either a P trap or an S trap.
- Test the water heater: Turn on the electricity, and make sure the water heater kicks on.
Installing a Storage Water Heater
- Turn off the electricity: Make sure you turn off the electricity to the area where you’ll be working on the water heater.
- Connect the water heater to an electrical outlet: If you’re installing a gas water heater, you’ll need to have your gas permit. Make sure the gas line is installed properly.
- Connect the water heater to the water supply: Make sure the water supply line is connected to the water heater.
- Install the drain line: The drain line is usually a special plumbing fitting: either a P trap or an S trap.
- Test the water heater: Turn on the electricity, and make sure the water heater kicks on.
Review the Water Heater Wiring Diagram
When you’re ready to install your water heater, use the wiring diagram to connect the wires. Be sure to follow the proper wiring and voltage rules for your area. If you’re wiring an electric water heater, connect the black wires from the breaker box to the black wires on the water heater, and connect the white wires from the breaker box to the white wires on the water heater. If you’re wiring a gas water heater, connect the black wires from the gas line to the black wires on the water heater, and connect the red wires from the gas line to the red wires on the water heater.
Conclusion
The water heater wiring diagram is the key to a successful water heater installation. Before you start, be sure you know the basics of water heater installation, the location you’ll be installing your water heater, and the type of water heater you’ll be installing. Once you have this information, wiring your water heater will be a breeze!
