Before buying a space heater, there are important factors that need to be had in mind for a preferred user experience to be met. From the heat produced by the product to the space that it will be used in, here are some of the factors to consider before buying a heater.

Factors to Consider Before Buying a Shed Heater

1. Floor Space

The size of your shed will determine the type of heater you will go for. The larger the shed, the more heat the room will need to maintain a good temperature. An electric heater would attract a high electricity bill for a large space. The cheapest option is wood as long as all the safety measures, like fixing a carbon monoxide detector, are taken. However, if space is smaller, the shed would be easier to heat and the energy bills will be more manageable.

2. Preferred Mounting Point

When planning to use a shed, one has a design for the space in mind. Where people will sit or sleep and which places will have priority over others in receiving the heat.

The heater for your shed could be wall-mounted or placed in a more appropriate spot depending on the design of the room and the safety of the occupants in the space. Heat output will determine how far or close the heater will need to be from the people in the room. Unlike any typical electric heater, heating methods that involve fire have more stringent safety measures and have to be put in open places away from walls.

The heating method is a huge factor for where to place the heater. Wood needs a fireplace while a product like a fan heater with a carry handle can be moved from one point to another easily. The best heater for your shed will therefore depend on the type of space that is available.

3. Size of the heater

Different living spaces have different sizes and so are different sheds. A smaller shed heater would be easier to carry around with other equipment when traveling and larger space heaters like a pellet stove need more permanent installations. A smaller heater can be moved around the room or wall mounted as their design allows for flexibility.

4. Electricity

Whether the shed has electricity or not will be a factor in choosing a heater. Sheds will most likely not have electricity because of the nature of utility that normally does not require heating.

The best shed heaters for a space that would not require electric heaters can include propane heaters, kerosene heaters, gas heaters, and so on depending on the safety preference appropriate to the unit being heated.

Sheds that have electricity have a variety to pick from. The most important thing to consider would be energy efficiency while having energy bills in mind. Depending on the shed design, the access point of the electricity has to be considered to determine whether the heaters would be wall-mounted or placed anywhere else in the space. The best thing about electricity is that it can be pulled to a preferred spot inside the shed.

5. Shed Insulation

Sheds that are uninsulated would not keep in the heat despite the fact that one could have the best shed heater in it. Maybe a shed was a workshop and needed a good amount of air circulation. When air is heating, circulation happens at a faster pace. Hot air rises and is replaced with cool air. This makes it virtually impossible to heat up a shed that is not insulated. A garden shed has a different design depending on its purpose and is insulated in some instances. Before installing a heater, a shed has to be insulated to make the shed heater energy efficient and to make the best use of the heat output.

6. Budget

A shed heater will be cheap or expensive depending on the heat output, size, usage, built-in thermostat quality, and how energy efficient it will be. An oil-filled radiator will be cheap to run making it more efficient since the oil in the heater does not need to be often changed. Installing electrical appliances for electric heaters will be costly. Heaters that use gas like propane canisters or wood needs a well-ventilated space which can take up some cost when redesigning a workshop or garden sheds.

Spending more on a heater has its advantages. Heaters will come with a better adjustable thermostat for better regulation of the temperature and remote control for comfort. Power settings in expensive haters give a wider range of options. Expensive heaters have more heating power and more sensitive to come with a built-in thermostat. Heaters like the oil-filled radiator have the ability to detect oxygen while regulating the temperature. Bio green pal 2.0 has an adjustment range making it a more focused space heater.

7. Storage Space

You definitely have to know where the heater is going to fit, whether in the car or the storage unit.

8. Type of Heater

The heaters can be classified into two types

  • Electric
  • Non-electric


i. Electric Heater

These are heaters that need an electricity source in order to be powered. They include:

  • Oil-filled radiator-It is a form of the convectional radiator which heats up oil which in turn heats up the room by losing heat to the environment. An oil-filled radiator is probably the best heater for a shed due to its high safety standards.
  • Fan heater-Also called a blow heater, the fan passes air over a heater element. The air is heated and in turn, the room since the hot air is pushed out by the fan.
  • Halogen heaters-unlike heaters which have electric coils or elements, the halogen heater works by warming halogen enclosed in a holder which in turn heats the room. Much like the halogen lamp, they provide a direct heat source.
  • Convection heaters-These work by heating a coil that produces hot air. Some blow up the heated air in order to distribute it into the room.

ii. Non-electric Heater

These are heaters that do not need electricity as a source of heat. They include:

  • Wood- A cheap source of heat, wood can be used in fireplaces. Heat is regulated by adding or reducing the amount of wood in the fireplace.
  • Pellet- Compressed wood pellets, although fed into the heater electronically, are burned to warm up a room. Fuel is more controlled when using pellets, unlike wood.
  • Kerosene-A very cheap method of heating. However, it needs good ventilation. It is therefore not the best heater for a shed.
  • Propane heater- Installed in homes using a heating system, warmth is distributed using vents. This would be very expensive to set up in a shed. They are very durable and can last up to 15 years. Alternatively, propane can be used in a propane heater stove or oven making it very efficient. A propane heater can be used in a shed as long as safety standards are met.
  • Natural Gas Heater- Heat is generated in a furnace burner and passed through a heat exchanger and into a ventilation system.


Specifications to Look Out For When Buying a Heater

In order to get your money's worth, the heater you are getting for your shed needs t0 meet certain standards. The following are a few specs to check when buying a heater.

1. Remote Control

If the heater is electric, it needs to have remotely controlled features. This makes it possible to mount heaters in spots that are safe for having children around. Some heaters have exposed heating elements that can cause accidents in cases of spillage. A remote control makes it very convenient for you as a user.

2. Sealed Heating Elements

Heating elements produce heat. If left unsealed, there is a chance that an accident could occur. Just like a fan heater needs to have its fans covered, the heating coils need to be covered as well. Spillage can cause electrical short-circuiting and therefore extra care needs to be taken.

3. Casing

Plastic casing will probably produce a burning plastic smell when running at high temperatures. This can be off-putting and can cause false alarms every other time with people worrying that there could be a fire.

4. Thermal Cut off

This is a safety device that will protect your shed from accidental fires by cutting off a circuit in case of overheating or when the heater exceeds a given temperature. A heater should be able to have the best safety features as electricity is involved. Heat settings and the adjustable thermostat should be able to work efficiently for maximum efficiency of the heater.

5. Anti-freeze Features

A shed probably experiences low temperatures and a heater should be able to automatically turn on so that the shed is kept warm even when no one is around. This feature also keeps the heater running at an optimum level.

6. Warranty

Just like any product, a warranty is very important. It helps you discern the customer service and when getting a heater for a shed, you need it for the longest run.


Shed Heater Frequently Asked Questions, FAQs

1. Can Heaters Be Left Overnight?

A modern heater from a reliable company with the required build standard should be safe to use overnight. The thermostat should be in good shape. Some products have a feature that can detect low oxygen levels and automatically shut off making them safe products to use overnight.

2. Can a Heater Catch or Cause Fire?

Yes. Space heaters are a leading cause of fire and safety measures should be followed with the strictest caution. Even the best heater for a shed would be prone to an accident if not handled with care. The thermostat should be fixed immediately when broken.

3. Can Heaters Cause Carbon Monoxide Poisoning?

On their own, heaters that use electricity very rarely cause carbon monoxide poisoning. The chances of that happening are only limited to heaters that use fuel. Home-based heaters should most preferably be electric. These have thermostats that regulate heat to prevent third-party fires.

All these considered, you will be able to choose from the best shed heaters and walk home with just the right heater for you.
