In this post, we will discuss the Diagram of a Gas Water Heater | Water Heater Parts Diagram. The gas water heater is the main device used in our homes and provides hot water to use for different purposes. washes dishes and for laundry purposes. These heater uses natural gas or propane for fuel and comes with different components such as a gas burner assembly, thermostat, and tank for storing hot water.
To ensure effective operation and safe use of water heaters, one must have an understanding of the simple water heater diagram and its parts of water heater diagram. So let’s get started with a Diagram of a Gas Water Heater
Cold Water Inlet
The cold water inlet helps the cold water supply to enter the unit when open. We can close the connected valve to prevent water from filling the tank for maintenance and repairs
Dip Tube
The dip tube moves cold water from the water supply to the lower part of the water heater, here it is heated before mixing with the remaining of hot water
T&P Relief Valve
The temperature and pressure relief valve helps pressure to be released from the tank when temperature and pressure levels is high.
Overflow Pipe
The overflow pipe is a component of copper or flex line that hangs down from the T & P relief valve on the external of the tank. This pipe offers an outlet for extra pressure to release the tank if the temperature and pressure are high

Main Parts of a Water Heater
If there is a need to know the working and the main parts of the water heater. All gas, oil, and electric heaters come with these pats
Anti Corrosion Anode Rods
Tanks come with one or two magnesium or aluminum anode rods for protection of exposed steel from corrosion. They are also called anti-corrosion or sacrificial anode rods. There are normally two rods for extra protection with a longer warranty. magnesium anode rods are good to use in soft waters. If it has hard water then an aluminum anode rod is good for the device. With that hot water tank becomes contaminated with desulfovirbiro bacteria.
Powered Anode Rod
We can vary the anode rod that has hot water heater. There are many advantages and differences between powered anode rods. Powered anode rods, created with titanium and coming with a current rectifier that plugin, are more effective than conventional sacrificial magnesium anode rods. The rectifier makes a small current in the water, that have many advantages. it decreases sulfur smell in your water, avoids tank corrosion, and reduces limescale buildup.
Cold water Shut-off valve
The incoming water supply pipe to the water heater comes from the water softener or conditioning system, or through the main line. it should be a cold water supply shut-off valve on the supply side close the water heater so water can be off for repairing
the Inlet Pie, Outlet Pipe, and Dip Tube
The inlet at the top of the tank sends cold water to the lower of the tank through a dip tube. That prevents cold water from cooling down hot water. Hot water left the tank from the outlet at the top. in comes conditions there are inlet and outlet pipes in opposite directions. After that cold water goes to the top of the tank since it is not passing through the dip tube. If someone wants to get a shower is going to face a blast of cold water
Temperature-Pressure Relief Valve
The hot water heaters should be protected with a relief valve called a temperature pressure relief valve. The TRP helps water to come out if the temperature or pressure is high in the tank. This element is a safety parameter that saves the tank from blowing up. it must be mounted on top of the tank or at the side of the tank six inches from the top. If there is a relief valve on the hot water pipe over the tank, there is an old type of tank that must be replaced. This has not worked for a long time and is not safe.
Operating Controls and Thermostat
Water heaters are made to output water at 140 degrees and can be set to use with a thermostat. Mostly range between 115 and 120 C is safe and energy effective. We can set thermostats on electric water through the use of a screwdriver. The gas water heater comes with a dial or knob thermostat at the control unit
Drain Valve
Each water heater must come with a drain valve at the base of the tank. With this, we must drain some gallons of water for many times to get rid of sludge in the tank
What Size Water Heater Do You Need?
Family Size | Demand | Gallon Capacity |
---|---|---|
1-2 people | High Regular/Low | 40 to 50 gallons 30 |
2-3 people | High Regular/Low | 40 to 50 gallons 40 |
3-4 people | High Regular/Low | 50 to 75 gallons 40 |
5+ people | High Regular/Low | 75 gallons 50 gallons |
How Long Before a Water Heater Recovers
Water Heater Type | Recovery Time |
---|---|
Electric | 2 hours |
Gas | 1 hour |
Oil-fired tank (120 gallons) | 1 hour |
High recovery rate (15-30 minutes) | 15-30 minutes |
Where Should You Place Your Hot Water Heater?
The best place is to put it in our homes and possibly to water connection. The bathroom can be the best area for a water heater connection since hot water can easily be used. it is easy since the accurate drainage and waste pipes are connected
Working Principle
The gas water heater works through the use of a gas burner for heating water in the tank. The burner is ignited through a continuous flame known pilot light, which makes sure for fast start-up whenever hot water is required. When the burner is lit, the heat produced is transferred to water in the tank by the heat exchanger.
The temperature of the water is sensed by a thermostat that triggers the burner to turn on or off based on the water temperature. heated water moves to the upper part of the tank due to the heat-rising principle. That makes sure hot water is at the top point of the tank. Gas water heaters need a ventilation system to exhaust byproducts of combustion, like carbon monoxide, outside of the home. That make sure safe and healthy conditions in the house when using gas water heater

Faqs
How does a gas water heater works?
The burner is centered in the bottom head and flume. Gas is ignited at the burner through the pilot light. The combustion transfers heat to water through the flume and bottom head of the tank. Gas water heaters burn natural gas or propane called LP fuel
How do you run a gas water heater?
- off the ga and open the pilot light access door. First of all off the gas to hot water heater for five minutes
- Find burner
- Select the gas knob to pilot
- Reduces pilot light
- On the gas back completely
- Replace the pilot light access door or cover
How do instant gas water heaters work?
Tankless water heaters function by using an electric or gas burner. The power supply heated water since it move through a pipe to the unit. it provides a near-endless supply of hot water. The water heater offers instantaneous comfort and ease
What are the steps to install a water heater?
- Set new heater at location
- Connect T and P valve
- Connect discharge pipe
- hook up water
- Connect fittings
- Secure the fitting
- Secure compression nut
Can I install a gas water heater myself?
Connect gas water heat is not a DIY operation for some users anyone not easily learn how to install a gas water heater in some days. it can be dangerous to get the operation on if you are not ready and have plumbing knowledge.
Is it safe to use a gas water heater?
Gas water heaters burn natural gas or propane to heat water, which can generate carbon monoxide. If not accurately vented or if there are leaks or malfunctions carbon monoxide can casues health issues. regular maintenance and accurate installation can be important to solve the risk
Do you need electricity for a gas water heater?
The gas water heater uses a pilot light or a small flume for igniting a gas burner that heats the water. Due to this gas water heater not need an electric source to operate since it can work without power
How much power does a gas water heater use?
The average water heater operates about 1125 watts some high-power water can be used at 4000 watts
What power does a gas water heater need?
Water Heater Type | Min Wattage | Max Wattage |
---|---|---|
Electric | 2500 | 4500 |
Gas | 30000 | 100000 |
Will a gas water heater work without water?
If the water pressure is lost on the cold water part the table can siphon down through the cold water inlet till it gets lower of the dip tube. So it no water in the tank to absorb heat the dip tube can melt and the tank gets damaged.
Why do gas water heaters fail?
if your comes with hard water which is heated in the water heater sediment can created on the lower part and clog water passages
What fails on a gas water heater?
In the gas water heater faulty gas connection, bad pilot light, or bad burner can cause not water heat
What happens if the gas hot water heater is empty?
it reduces water pressure or low water level in the tank causing the heater part to overheat and burn out
