What Are Hole In The Wall Gas Fires?

There are so many various types of fireplaces for sale, and we wouldn’t blame you for losing track of which one is which!

A hole in the wall gas fire is almost precisely as it seems – a sleek, easy to install a fireplace that fits into a hole in your chimney breast or wall. They come in many different sizes and styles, producing real flames and giving off highly-efficient heat from their frontal glass panels.

Why Might You Want A Hole In The Wall Fireplace?

One of the biggest reasons people choose any wall mounted gas fire is to save on space. Although, inset gas fires go a step further than merely hanging on your wall by sitting inside a wall or chimney hole, meaning they run as flat against your wall as feasible. This can help make your room appear larger and is ideal for those working with compact space.

Another reason for their appeal is their beautiful and versatile appearance. Whether you want a classic look, a twist on the traditional or some truly contemporary wow-factor for your chosen room, a hole in the wall gas fire will deliver when it comes to style.

Mastergas (Ed) fitted a thermostat for us, which I am glad we did, not only for the reason that mastergas advised us too as it would be beneficial both economically & financially but for the fact that we chose mastergas for the job. Friendly, polite, courteous, professional & honest service. One of the best tradesman services ever received. Whilst here the boiler was playing up which Ed (mastergas) had a look at, now not only do I have a house that is not too hot or too cold but perfect! (Thermostat) the boiler is working as good as new, thanks to mastergas. Would definitely recommend & implore you to choose mastergas should you require to do so. Very happy customer.
