Understanding how to tell if a water heater is gas or electric is essential for homeowners. If you are dealing with issues like repairs,energy bills and safety concerns, knowing about the type of your system is very important and it saves your time and money also. This is the common question among people and at MileHi HVAC we often receive calls where homeowners are confused related to type of their system. In this guide you will be clear about practical ways to identify a water heater, how it works and then you can confidently make informed decisions.
Importance of knowing about your water heater type
Knowing related to your water heater is beneficial for several factors like installation, maintenance and operating costs. As gas and electric heaters work differently, they vary in efficiency and cost. So if you don’t have any idea whether your water heater is gas or electric you waste money on buying incorrect parts, DIY maintenance and many other things.
Inspect external fuel indicators
One of the simplest ways for understanding about your water heaters is to check what is connected to it.
Gas water heater signs
Gas heaters are connected to the gas supply line and there is a vent or fuel at top that releases combustion. The vents are made up of metal and for combustion they lead upwards towards the wall.
Electric water heater signs
Electric heaters have no vents; they only contain access panels which are located at the side of the tank.These two or more panels cover the internal heating elements. So if your system has no gas line or vent it means it is electrical.
Inspect heaters power source
Another easiest method for how to tell a water heater is gas or electric to determine through which type of source the heater is operating.
- Gas units operate through gas from gas pipe lines and may have pilot lights.
- Electric units operate through electricity and these are connected with home electrical systems and contain a circuit breaker.
Check out manufacturer plate or label
When you buy any type of heater there is a label with it. If you are unsure about the system you can seek help from that. It systems whether the unit is gas or electric, model number and voltage and fuel type. By reading that label you will identify your system.
Our team at MileHi HVAC also uses these labels during inspections for efficient servicing and safety compliance.
How each type functions
There is a question: do water heaters use gas or electricity exclusively? The answer depends upon the type of model installed in your home .
Like gas water heaters use gas supply to deliver hot water for you however electric water heaters heat through heating elements. In your system if you see a faint flame it indicates that it is the gas system. It shows that yes to the question, do water heaters use gas when designed for that fuel source.
Check your energy bills
Through your energy bills you get signs and clues for how to tell if a water heater is gas or electric. If there is a sudden increase in your gas bills after water heater installation, that is a gas water heater. On the other hand if there is an increase in electricity bill then it means the water heater is electrical.
Most homeowners are confused that are water heaters electric by default? Not necessarily. You got to know through the utility bills of your home if the water heater is one of the largest consumers.
Installation and Location
One of the factors for identifying the type of water heater is through the location and installation style of your system. Gas water heaters are usually installed in basements and garages for the purpose of proper ventilation. Electric water heaters are placed in smaller places and closets due to their vent free design.
Sometimes the question arises: are water heaters electric in apartments? So Yes but always verify things before moving to results.
Misconceptions about water heaters
Our team hears frequent myths like are all water heaters gas? The answer is definitely no. In this modern era there are ranges and varieties of water heaters both gas and electric and are available depending upon the household needs.
Another misconception about heaters is that new homes prefer electric heaters and there is less demand of gas heaters. This is wrong; many homeowners are still using gas heaters for fast performance and less operational costs. So are all water heaters, gas is a definite no.
