Whether you’re moving to a new house, squeezing a water heater into a tight space, or just trying to get one into your truck, you’ve probably wondered if it’s safe to lay the thing on its side. If you’re moving a water heater as part of a replacement, see how long it takes to replace a water heater.
The short answer is yes — with some important caveats. Here’s what to know before you tip it over.
Laying a water heater on its side is safe in most cases, but gas-powered models require extra caution to prevent gas line damage. Always drain the tank, secure the unit with straps, and orient the inlet and outlet valves upward.
Can You Lay a Water Heater On Its Side?
Yes, in most cases you can lay a water heater on its side. This is usually necessary when the heater is being installed in a tight space or when you need to transport it and fit it into a vehicle.
There are, however, a few exceptions. If your water heater is gas-powered, you’ll need to be extra careful when handling it.
Gas models are more susceptible to leaks and explosions if not handled correctly, so make sure to follow all the manufacturer’s instructions carefully. Learn more about how gas water heaters work before attempting to move one.
As long as there’s no chance of the gas line being kinked or damaged, laying the water heater on its side should pose no problems. Just be sure to follow any special instructions that may be included with your particular model.
The Dos and Don’ts of Laying a Water Heater On Its Side
There are several things to keep in mind if you decide to lay your water heater on its side.
- DO research the type of water heater you’ve before attempting to move it — compare boilers vs water heaters for handling differences
- DO use straps or another type of support when moving the water heater to prevent it from tipping over
- DO orient the water heater so that the inlet and outlet valves are pointing up when you place it on its side
- DO secure the lid of the tank before moving the water heater
- DON’T attempt to move the water heater yourself if you’re not confident in your strength or ability to do so. It’s best to have at least one other person help you with this task
- DON’T place the water heater on its side until you’re ready to install it in its new location. Once it’s on its side, gravity will start to work against you and make it difficult to move again
- DON’T forget to secure the lid of the tank before moving the water heater. A loose lid could come off and cause serious damage
These are just a few of the dos and don’ts to keep in mind when laying a water heater on its side. Following these guidelines will help make sure the job is done safely and correctly.
How to Transport a Hot Water Heater
Water heaters are relatively easy to move without damaging them. If you’re planning a DIY project, first check whether a homeowner can install a water heater. Here is a step-by-step guide on how to do so.
Disconnect the Power Supply
This is an important safety precaution and will prevent any accidental electrocutions. Know what size breaker your water heater uses before disconnecting.
Turn Off the Water Supply
This will help prevent any leaks while you're moving the unit.
Drain the Water From the Tank
This will make the water heater much lighter and easier to move. Be careful not to let the tank freeze if draining during cold weather.
Remove Attachments
Remove the anode rod, temperature/pressure relief valve, and any other attachments. These can usually be unscrewed by hand. You'll need to know what size socket fits a water heater element.
Lift Onto a Dolly
Lift the water heater tank onto a dolly or other moving platform. If you don't have a dolly, you can use a strong piece of plywood.
Secure With Straps
Secure the tank in place with straps or rope to prevent it from tipping over during transport.
Transport and Reconnect
Transport the water heater to its new location carefully. Reconnect the power supply, turn on the water, fill the tank, and check for leaks before turning on the heat source. Learn how long a full installation takes.
What Are the Best Transportation Methods for a Hot Water Heater?
There are a few factors to consider when choosing a transportation method for your water heater.
One factor is the size of your water heater. A 75-gallon water heater or 100-gallon water heater will definitely need a truck or trailer to move.
A smaller 19-gallon water heater might be able to fit in a car.
Another thing to think about is how far you’re moving the water heater. If it’s a long distance, you’ll want to choose a method that will minimize the amount of time it spends in transit.
And finally, you’ll need to think about how much money you’re willing to spend on transportation.
With all of these factors in mind, here are some of the most popular methods for transporting water heaters.
One option is to rent a truck or trailer from a moving company. This is usually the best option if you’ve a large water heater or if you’re moving a long distance.
The only downside is that it can be expensive.
Another option is to ask friends or family members if they have a truck or trailer that you can borrow. This is often cheaper than renting, but it may not be an option if you don’t know anyone with a suitable vehicle.
Finally, you can try to find someone who specializes in water heater transportation. These services are usually fairly inexpensive, but they may not be available in all areas.
Whichever method you choose, make sure to plan ahead so that your water heater arrives safely at its new home. After moving, check for low water pressure issues that could indicate transport damage.
Frequently Asked Questions
Maybe, if it's a small one. Most standard water heaters are too big for a car, but a compact 19 or 30-gallon tank might squeeze into an SUV or minivan with the seats down. For anything bigger, you'll want a truck or trailer.
If you're moving your water heater a long distance, choose a transportation method that minimizes transit time. A truck or trailer is best for long-distance moves. Make sure the tank is fully drained and all connections are secured.
No, you should always drain the water from the tank before you try to move it. This makes the water heater much lighter and easier to handle.
If you're not sure whether your water heater is too heavy to lift, it's always best to be cautious and ask for help. Water heaters can be very heavy, and lifting one without proper support can lead to serious injuries.
Final Thoughts
Moving a water heater on its side is totally doable — just don't wing it. A little preparation makes all the difference.
Drain the tank completely, grab a helper (these things are heavier than they look), and strap it down with the valves pointing up. If you've got a gas model, be extra careful not to kink or damage the gas line.
With some basic planning and an extra pair of hands, you'll get it moved without any drama.
