Which type of Garden Room heater is best for you?

If you use your garden room all year round, you will need a garden room heater for the colder months, Electric heaters are the popular option, but there are lots of choices out there.

In this article, we’ll compare five different garden room heaters, Electric convection heaters, Electric oil-filled radiators, Electric fan heaters, Air conditioning, and Wood burners.

We’ll explain how they’re different from each other and why you should consider each type when heating your garden room.

Electric convection heater

Electric convection heaters are the most common garden room heaters. They are excellent for year-round use, as they heat the air quickly and can be free-standing or wall-mounted.  And are completely silent when running.

Most are available with 24-hour timers and are thermostatically controlled, some have smart controls that enable you to control them from anywhere, which is ideal for pre-warming an office before your day begins.

They are relatively cheap to buy and install.

Electric oil-filled radiators are also silent when running and tend to be free-standing, which offers flexibility but they take up floor space.

These take longer to heat the room than convection heaters, but the oil retains heat, maintaining warmth for longer after they are switched off, which again can be controlled via a thermostat, timer, or smart controls.

They are low in cost with no installation required.
