How Much to Remove Gas Wall Heater?

When you’re planning to remove a gas wall heater, it’s important to know how much of the wall it will take with it. If you don’t plan for enough space around the heater, you could end up having to rip out drywall and start over. In this post I’ll go over some guidelines for how much clearance you should allow when removing a gas wall heater.

How Much Is The Cost To Remove Gas Wall Heater?

There is no doubt that gas wall heaters are one of the most efficient ways to warm your home. However, like with any appliance or piece of equipment in your house, there will come a time when you need to remove it. The question is, how much does it cost?

How much does it cost to remove gas wall heater? The answer is that it depends on what type of heater you have. For example, if you have a vented heater, which is typically the most common type, then removing one will cost around $50-$200. However, if you have an unvented gas or electric heater, then the price increases dramatically and could be anywhere from $250 up to over $1000.

Gas wall heaters are easy to remove.

Removing a gas wall heater is simple and straightforward. With the right tools and a little bit of know-how, you can remove and replace a gas wall heater in as little as one hour, provided the size and weight are no larger than standard models. However, if the model you want to remove is too large or heavy for you to lift on your own, then it’s best to call in professionals for help.

In order to safely remove your gas wall heater from its current location, use a pair of pliers or another tool with sturdy grips that are suitable for gripping metal surfaces like pipes. You’ll also need some sort of protective gear such as goggles or glasses because working with materials like copper will produce airborne particulate matter that may irritate your eyes or lungs if not properly protected against them beforehand.

Do not leave the gas line open or cap it off.

It is important to cap off your gas line so that it doesn’t leak and cause problems. If left open, the gas can leak into the air, creating a safety hazard. If the pipe is capped off, there’s no risk of carbon monoxide leaking into your home. You will also want to make sure that you don’t try to turn on the wall heater while it’s still connected; this could lead to an explosion or fire.

Remove the flue cover.

The flue cover is a metal plate that sits directly over the gas line. Use a screwdriver to remove the screws holding it in place, and remove it from your wall. This will allow you to inspect for damage and make sure there are no leaks in your gas line before continuing with your project.

If there is any damage to your flu, contact a professional so they can make repairs according to code regulations and ensure that everything is safe for use again.

Disconnect the gas line from the heater.

To remove the gas line, use a wrench to loosen the connection between the heater and the wall. Make sure that there is no leakage from this connection. If you have trouble loosening it, apply heat from a blow dryer or hair dryer to warm up the pipe and make it easier to remove. Once you have successfully disconnected the line, check for any obstructions such as holes or cracks in your wall that could trap your gas line. This is especially important if you don’t plan on replacing your old heater yet—you don’t want a small hole exposing yourself to carbon monoxide poisoning!

Remove the gas wall heater.

To remove a gas wall heater, you’ll need to first remove the screws that hold it in place. There are usually three different sets of screws:

  • Screws that hold the heater to the wall (usually four or six)
  • Screws that hold the flue pipe to the base of your gas wall heater (usually six)
  • Screws that hold your gas wall heater to its cover or thermostat (each).

Dispose of the gas wall heater properly.

Dispose of the gas wall heater properly. Call an HVAC service to dispose of the gas wall heater for you, or check with your local laws to see if you can dispose of it yourself. If so, check with your local waste management agency to see if they accept it.

Follow these steps to remove a gas wall heater.

To begin, follow the manufacturer’s instructions to remove the old wall heater. Make sure you turn off the gas and electricity before you do anything else. Next, shut off the water supply to your house so that no one gets hurt by carelessly working around it.

Next, carefully remove any wires connected to your new wall heater unit and unplug them from their outlets for safekeeping until installation time arrives. Take out any screws holding it in place in order to take it out of its housing; then set aside all pieces on an appropriate surface such as a table or ground near where you’re working on this project (but not inside your car or truck).


After removing the gas wall heater, you can begin installing your new one. You can install it yourself or hire a professional to do it for you. The cost of replacing a gas wall heater will vary by brand and model but generally ranges from $500 to $1000 depending on where you live and how much work is involved.
