The safety of having an attic hot water heater is a pertinent concern for many households, as this essential appliance provides hot water for various daily activities like showering, dishwashing, and laundry.

Attic spaces can be hot, cramped, and difficult to access, which can make maintenance and repair tasks more challenging. Additionally, water heaters can pose a potential hazard if not established correctly, which could result in leaks, fires, or even explosions. In this blog post, we will explore the safety considerations of having a water heater in the attic and provide some tips on how to ensure that your water heater is installed and maintained safely.

What are the benefits and drawbacks of having a water heater located in the attic?

There are both pros and cons to having an attic hot water heater installed in the attic. Let’s take a closer look:


  • Space-saving

With limited space in some homes, installing them in the attic can free up valuable square footage in living areas.

  • Continuous flow

Tankless water heaters, which can be installed in the attic, provide continuous hot water on demand without the need for a storage tank.

  • Energy efficiency

A heat pump or solar hot water system installed in the attic can be highly energy efficient, resulting in lower running costs and reducing your carbon footprint.


  • Water damage

If a water heater leak occurs, it can cause significant damage to your home’s ceilings, walls, and floors. To mitigate this risk, a drain pan should be installed underneath the heater.

  • Attic spaces 

Attics can be difficult to access, especially during the summer months when they can become hot and stuffy. This can make maintenance and repairs more challenging.

  • Installation costs

Depending on the type of heater, installation costs can be higher if it needs to be installed in the attic, as additional plumbing and electrical work may be required.

  • Safety concerns 

Gas storage tank-type water heaters in the attic can pose a fire risk, and there may be a risk of carbon monoxide buildup if the ventilation is inadequate.

Having a water heater in the attic can be a good idea if space is limited and you choose a safe and energy-efficient option, such as a tankless or a heat pump. However, it’s important to consider the potential risks and take steps to ensure that your heater is installed and maintained properly to prevent water damage or safety hazards.

What are the safety concerns and precautions that need to be taken with attic water heaters?

When it comes to attic water heaters, there are several safety concerns that homeowners should be aware of. Here are some precautions that can help ensure your attic water heater is safe:

  • Proper installation 

Make sure your electric storage or hot water heater is installed by a licenced professional who follows all local building codes and safety regulations. Improper installation can result in electrical hazards, water leaks, and even fires.

  • Ventilation

Ensure proper ventilation to prevent the buildup of carbon monoxide and other toxic gases. This is particularly important for gas storage hot water heaters.

  • Drain pan

Install a drain pan underneath the heater to catch any leaks and prevent water damage to your home. Regularly check the drain pan for any signs of leaks and address any issues immediately.

  • Access

Ensure there is safe and easy access to the water heater for maintenance and repair. This may require installing a pull-down ladder or creating a platform to stand on.

  • Insulation

Properly insulate any pipes or fittings that may be exposed to prevent heat loss and reduce the risk of fire.

  • Regular maintenance

Schedule regular maintenance, including flushing the tank, checking for leaks, and inspecting the anode rod. This can help prevent problems before they become serious.

  • Fire safety

Keep the area surrounding the water heater clear of any flammable materials, such as insulation or cardboard boxes. Consider installing a smoke detector in the attic to alert you in case of a fire.

By taking these precautions, you can help ensure that your attic water heater operates safely and efficiently, providing hot water for your household without any unnecessary risks.

What are some other possible locations to put a water heater?

If you are considering alternatives to an attic water heater, here are some other possible locations to install them:

  • Basement

The basement is a common location for them as it provides easy access for installation, maintenance, and repairs. This is also a good location for gas storage tank-type water heaters as they require ventilation.

  • Garage

The garage is another popular location for them as it provides adequate ventilation for gas storage tank-type. It may also be more convenient for homeowners who use the garage as a workshop or storage area.

  • Closet

If you have limited space, consider installing them in a closet. This can be an electric storage tank-type or tankless, depending on your needs and space constraints.

  • Outdoor shed

For those with larger properties, an outdoor shed can be an option for water heater installation. This can be a good option for those who want to free up space inside their home.

  • Crawlspace

If you have a crawlspace under your home, this can be a viable location for them. However, this location may require additional insulation to prevent heat loss.

When choosing a location for your water heater, it’s important to consider factors such as ventilation, space, access for maintenance and repair, and your household’s hot water needs. Consulting with a licensed professional can help you determine the best location and type of water heater for your home.

In short, having a water heater in the attic can be a viable option for homeowners, but it requires proper installation and maintenance to ensure safety and efficiency. While there are some risks, they can be minimised by following safety precautions such as proper ventilation, installing a drain pan, ensuring easy access for maintenance and repair, and regularly monitoring for leaks and other issues. 

Additionally, homeowners should consider other possible locations for water heater installation if an attic installation is not suitable for their household’s needs.
