Can you install a water heater in a shed?
Water heaters are a must-have in homes for showers, washing dishes and laundry. But what if you need to install a water heater in a shed? Whether you’re building a garden retreat, setting up a workshop or just need a water source for an outdoor area, installing a water heater in a shed can be a great option. But before you do, here are some things to consider to make sure it’s safe, effective and compliant.
Can you install a water heater in a shed?
Yes, you can install a water heater in a shed, but it requires some planning and attention to detail. Many people choose sheds as a location for water heaters because they are away from the main house. But the suitability of your shed for this installation depends on many factors, including space, ventilation, insulation and electrical or gas connections.
Experts at Metropolitan Hot Water advise always consulting a licensed plumber to assess whether your shed is suitable for a water heater. They can recommend the best type of heater and the most efficient installation method.
Types of water heaters for a shed
When choosing a water heater for your shed, you have two options:
- Electric Water Heaters: “These are easier to install and maintain. Electric water heaters are suitable for smaller spaces or sheds where gas installations may not be practical, provided the shed has a stable power supply,” says Expert from Metropolitan Hot Water.
- Gas Water Heaters: These heat faster and are more energy efficient for larger water demands. If the shed has a gas supply, this might be the way to go, especially for larger sheds or outdoor areas that require a lot of hot water.
Things to consider before installation
Before you install a water heater in your shed, here are some things to think about:
1. Space and Size
The size of your shed matters. Water heaters take up space so you need to ensure there’s enough room for the unit and the plumbing and electrical connections. Measure your shed’s interior before you choose a model.
- Small sheds: For smaller sheds, you might want to choose a compact or tankless water heater. These take up less space and can be wall-mounted.
- Large sheds: Larger units, like traditional tank heaters, require more space and should be placed in an area where they won’t obstruct movement or storage.
2. Ventilation
Ventilation is important, especially for gas water heaters. Gas units produce heat and gases that must be safely vented out of the shed. If your shed doesn’t have good airflow or a flue system, it may not be safe to install a gas water heater.
For electric water heaters, ventilation is less of an issue, but still important to ensure the shed doesn’t get too humid, which can affect the heater’s performance over time.
3. Insulation
The shed must be insulated to prevent heat loss. If the shed is not insulated well, your water heater will have to work harder to maintain the temperature, and your bills will be higher. In colder climates, if the shed is not insulated enough, the water heater can freeze in winter.
Make sure the shed has proper wall and roof insulation or add extra insulation before installation.
4. Plumbing and Electrical/Gas Connections
The shed will need plumbing and if you’re installing a gas water heater a safe and reliable gas supply. For electric models, you’ll need a dedicated power source.
- Plumbing: Connect the shed to your home’s water supply or set up a separate water supply system if you’re going to use the shed as a standalone unit.
- Electrical: Electric water heaters need a reliable power supply. You may need to upgrade the wiring or circuit to accommodate the water heater’s power requirements. This is best done by a licensed electrician.
- Gas: If using a gas water heater, the shed must have a gas line. And make sure the area is well-ventilated and the gas supply is safe to connect to.
5. Safety Regulations
Check local safety codes and regulations before installing a water heater in a shed. For example in many areas water heaters must be installed by a licensed professional to meet safety standards. Not complying with these regulations can result in fines or safety hazards.
- Electric Water Heaters: They must be installed according to the manufacturer’s instructions and local electrical codes. This means ensuring the heater is properly grounded and there’s no risk of overloading the circuit.
- Gas Water Heaters: They must be vented correctly to prevent carbon monoxide buildup. Many areas also require regular inspections of gas appliances.
6. Maintenance Access
Consider the maintenance access for the water heater. Water heaters need to be serviced regularly, such as flushing the tank to remove sediment, check the heating elements and look for leaks. Installing the water heater in a hard to access location may make future repairs more complicated and expensive.
Pros and Cons of installing a water heater in a shed
To help you decide if installing a water heater in a shed is for you here are the pros and cons:
Pros:
- Space saving: A shed is a separate space so you can save room inside your home.
- Less disruption: By having the water heater outside the home, the noise and heat from the unit won’t disturb your daily activities.
- Energy-efficient options: Depending on the model you choose, you may find an energy-efficient one that will save you money in the long run.
Cons:
- Freezing risk: In colder climates, water heaters in sheds can freeze if they are not well insulated.
- Higher installation cost: Depending on your location running water, gas or electricity to the shed may cost extra.
- Maintenance challenges: If the shed is hard to access or not well lit, maintaining the water heater will be harder.
Safety and Efficiency Considerations
You can install a water heater in a shed if you take the necessary precautions and consider the right factors such as type, safety, plumbing, temperature and local regulations.
If you’re thinking of this option, make sure to consult with professionals like a licensed plumber and electrician to ensure the installation is safe and meets all building codes. Then you can have hot water in your shed without worrying about safety and efficiency issues.
Remember that your water heater should always be suited to the specific needs of your shed, so you can enjoy hot water without any concerns.
