Today we’re looking at the Firefly Electric 900W rotating weatherproof patio heater.

Firefly Electric – 900W Electric Free Standing Heater

Great on a budget, fantastic for small spaces and intimate evenings.

If you’re looking for a small scale portable patio heater. Then you’re looking at the right item! The Firefly 900W patio heater is the perfect product for those who don’t want a bulky full sized patio heater, but still want to keep warm in the evening.

Weighing in at just 7kg, suitable for indoor and outdoor use as it is weatherproof. (IPX4 rated) meaning it can be used in damp conditions. Although you shouldn’t be using this in a downpour! It’s current price (£49.99 as of 9th May 2017), is a steal for a versatile portable patio heater.

Functional and practical, with 2 temperature settings. 450W/900W – making this one of the cheapest patio heaters to run on the market! It will heat up to 4sqm.

Running Costs

The Firefly 900W heater comes with 2 temperature settings, (450W/900W) so it is one of, if not the cheapest to run (on economy mode). Let’s get down to the maths.

With the current average price per kWh in the U.K residing at 12.2 pence. We calculate the hourly usage as follows:

900W heater running costs:

900W x 1 hour = 0.9 kWh x 12.2p = 10.98p
900W x 2 hours = 0.9 kWh x (12.2p x 2) = 21.96p

If we were to assume you used the heaters for 2 hours a night every night.

Full power (900W) our monthly electric bill will be £6.59

Low power (450W) we’d be looking at £3.30 per month.

As you can see this is definitely one of the cheaper to run patio heaters!

Suitable For

This really is a patio heater for the home environment. Due to it’s portability and simplicity, not to mention lower than average output and consumption we don’t feel like this patio heater would be suitable in a commercial setting.

Firefly 900W Streamline Rotating Patio Heater

There is a market for a product like this, low cost, low output, just enough to keep the chill at bay. Don't expect it to work miracles though!

Cheap and cheerful on a budget. We can’t fault this patio heater, but it’s a little lacking in settings and features.

If you’re looking for a small and portable patio heater, then this is definitely the one to get. However you should be aware that with the power cable being just 1.45m long you may struggle to find the nearest socket if taking it outside. So don’t forget to look at extension cords like the Status 13 A 4 Socket Cassette Reel with Thermal Out, or waterproof power extension cables as well!
