Electric fires are chosen mainly for the look and the instant, flue-free warmth. Check the current Amazon UK price, as fireplaces are discounted heavily outside the autumn peak.
How is the COSTWAY installed?
The electric fireplace is an inset / media wall fire, designed to be recessed into a stud wall, media wall or chimney breast. You'll need a correctly sized recess (check the required depth as well as the width and height) and a nearby socket or a spur fitted by a qualified electrician. Plan the opening before you build the wall - retrofitting a recess is far harder.
How much heat does this electric fireplace give out?
The COSTWAY is rated at 750W / 1500W switchable. Most electric fires top out around 2kW, which realistically takes the chill off a small to medium room rather than heating a large or poorly insulated space. Treat it as supplementary heating and a focal point rather than a replacement for central heating. The lower setting is usually the more economical everyday choice.
What size is the COSTWAY 40"?
The electric fireplace measures 40in wide. For inset and media wall fires, the width is the headline figure but the required recess DEPTH is what most often catches people out - always check it against your wall build-up before ordering. For freestanding and wall-mounted models, check the width suits the wall or alcove you have in mind.
What features does this electric fireplace have?
The COSTWAY offers remote control, thermostat, timer. A thermostat lets it cycle off once the room is warm rather than running constantly, which saves running cost. A remote is genuinely useful on an inset or wall-mounted fire you can't easily reach. Match the features to how you'll actually use it.
Are electric fireplaces expensive to run?
Running cost depends on the heat setting and your electricity tariff. At full output most electric fires draw around 2kW, so an hour at full heat costs roughly the same as running any 2kW heater - use the lower setting or a thermostat to cut that considerably. Crucially, the flame effect alone uses very little (it's just LEDs), so leaving the flames on without heat costs pennies.
