Similar to the three-sided hearth styled model, the Matchless 4 Sided Heat Machine Hole in Wall Gas Fire is able to produce a beautiful, aesthetically pleasing decorative element for any room while producing an impressive output of heat.The heating capacity of this fire allows it to create up to 4.4kW of heat when it's running and functioning at maximum capacity. It's also able to be adjusted to low-temperature settings by the owner, with either manual setting adjustments, or an optional remote control system that is available when placing your order. This heat output is the result of a highly productive operating system that runs at an 89% efficiency.The hole-in-the-wall style gas fire is also able to be customised with a variety of style and colour options. There are two different colour options for the outer layer, and two different fuel bed effect options as well. Those who purchase it are also given the option of having the fire set up to operate with a traditional chimney flue or as balanced flue option, making it a great option for more modern houses (built without chimneys) and older homes (which have flues intact) alike.
