Firefly – 4000W Table-Top Gas Patio Heater Review

Stainless steel beauty. Perfect for keeping the chill at bay while you and your mates play!

Fairly well reviewed, with a weighted base and made from durable high grade stainless steel. But how does it compare to other table-top patio heaters on the market?

With an adjustable 4000W of power, running on propane we think you’ll love this offering from Firefly. Offering a fully guarded reflector as well as advanced built-in safety features lternatives on the market, if you’re looking for this particular model you won’t be disappointed. Priced at £99.99 (as of the 31st of May 2017 – hover for latest price) we were pleasantly surprised at the build quality.

How long will my gas tank last in the Firefly 4000W heater?

We base these figured on full power usage. Your mileage may vary!

How much does the Firefly 4000W heater cost to run?

As we’re looking at gas heaters the cost of consumption below is based on ownership of an existing gas bottle, as these can cost anywhere from £15 to £39.99 new (and empty!).

A bottle of 13kg propane patio gas from Calor costs £32. This patio heater will use approximately 0.33kg of propane per hour at full power (4000W)

We calculate the hourly usage as follows:

4000W heater running costs:

13kg * 3 = 39 hours
£32 / 39 hours = 0.82p

At full power we can expect this patio heater to cost us approximately 82p per hour.
At half power we can expect this patio heater to cost us approximately 41p per hour.

If you’ve got the heater on full power for 3 hours a night we’ll get about 13 days usage before you’ll need a refill!

It’s not the cheapest heater on the market and costs a fair amount to run, but if you’re looking for a table-top gas patio heater that packs a punch then this is the one for you.

Is this patio heater suitable for home or commercial use?

We’d recommend using this heater in a home environment only as there are more suitable commercial patio heaters that are more fitting a commercial setting.

A great mid-range table-top heater. Although other users have reported difficulty putting the product together.

Firefly are a trusted brand, but they’ve fallen a little short of the mark with this one. There’s nothing really wrong with it, but by the same merit, there are better products on the market at a similar price-point. If this is the heater you want then go ahead. Otherwise shop around for a better deal.
