If you’re looking for an affordable no-glare heater for the home or business then the Firefly “Black Heat” 1.8kW patio heater could be your next purchase. With up to 9sqm of heat coverage and multiple power options, suitable for indoor and outdoor usage with an impressive weatherproof rating of IP55 and it comes with a remote control as well as timer and safety features.

This is quite possibly one of the cheapest no-glare heaters available on the market today!

Firefly – 1.8kW “Black Heat” Wall Mounted Weatherproof Patio Heater

This heater from Firefly offers a number of features that you usually only see on patio heaters priced in excess of £200 pounds. It has some drawbacks but you can’t expect it to have all the bells and whistles of the more expensive heaters!

Heating Area

According to the primrose website, this heater offers up to 9sqm of heat coverage.

Element Life & Heating Type

The black heat 1800W patio heater from Firefly boasts a lamp life of up to 5,000 hours. Offering instant infrared radiant heat. There are no replacement elements for this heater so once the element has expired you’ll need to recycle the unit. This isn’t a major issue as it’s a fairly affordable heater but certainly a drawback.

Power Settings & Specifics

Two adjustable power settings – 900W / 1800W

Supplied with a 2-metre long power cable and rated at 230v, 50Hz. 3-pin British standard plug included.


If you’re in the market for a no-glare ceramic wall mounted heater then this ticks all of the boxes for those of you that want heat without the harsh glow of a halogen bulb.

It comes in a standard aluminium silver with black ceramic panels. Measuring in at 109cm (length) x 23cm (height) x 4.5cm (depth) it’s a fairly compact heater!

Features & Extras

Supplied with a remote control and 5-hour timer.

Weatherproof Rating

Another major plus for this heater is the ingress protection level – IP55

Solid rating 5 – protected from dust and solids.

Liquid rating 5 – will run even when subjected to low-powered water jets. Usable whatever the weather.

Suitable For

We would recommend this heater for home users, usable both indoors and outdoors. As there are no replacement parts available and it has a limited heating area, commercial users may find that they are better off investing more money in one of the Veito range. Or in a low glare Optima Heaters patio heater.

Cost to Run?

At the price of £119.99 (check current price) the cost of running this heater before electricity is just over 2 pence per hour (£0.024).

To calculate our electricity costs we do the following (based on the UK average of 14.7p per kWh)

Heater running costs:

Full Power (1800W) – 1.8kW x 1 hour = 1.8kWh x 14.7p = 26.46p (per hour)
Low Power (900W) –
0.9kW x 1 hour = 1.8kWh x 14.7p = 13.23p (per hour)

Assuming we were to use this heater for 2 hours per day.

Full Power (1800W) – Our monthly electric bill will be £15.876
Low Power (900W) – Our monthly electric bill will be £7.938

An all-around affordable heater!

We’ve found this heater priced at £139+ on other sites. At the time of review it was £20 cheaper on Amazon with an optional 5% additional savings when buying more than one.

It is a good entry level no-glare patio heater, there are better on the market but for the price you’re paying you’re getting a good deal! As long as your expectations are realistic and you aren’t buying it with the hopes of it heating your entire patio area then we highly recommend this heater.
