Choosing An Efficient Gas Fire

Gas fires have come a long way in recent years. They have become more efficient and come in many sizes and for some you don't even need a chimney.

In this video, I demonstrate (very simply) how a gas fire works and walk you through some of the gas fires types available, so that when you come to our gas fire showroom or visit any other, you will have a better idea of what you need to ask to meet your personal requirements.

Below is a text of the video.



Hi. today I would like to talk about why gas fires all of a sudden become really popular. obviously we've had the wood burners, gone through a fashion point, if you like, and they have been really popular for the last sort of eight to 10 years. Gas fires all of a sudden, well, in the last year especially, have become more and more popular and there's reasons for it.

So the one of the main ones is efficiency and people don't realise just how efficient gas fires can be now because they’re used to the older types and they imagine that they haven't moved on. But in fact, they really, really have.

So I just want to explain why they're more efficient. because I'm finding when customers come in until such time, I've explained it properly. they don't really get it.

So once it's pointed out, it might actually, help you decide before you even go visiting showrooms. which way you want to go, whether it be electric, gas, or wood burning.

But so many of our customers are actually coming in wanting a wood burner when they're told about the gas fires and what's available, all of a sudden they, jump to a gas fire idea.

Okay, to explain, this is what I'd normally explained to a customer when they come in. This is a traditional old style, what we call the 16 inch standard gas fire. The way they work is you got a box with reflective panels in it, which reflects heat.

You've got controls under here, which basically control a burner like a, like a cooker anything else that has a burner underneath. The burner puts flames through the coal fuel bed. The colds glow up and it all becomes nice and hot in there. So that's reflecting heat forward. Okay, so what you're getting is radiant heat….

A bit like sitting in the sun. You go in the shade, you're cool, you go into the sun, you feel the radiant heat. That's how these radiant gas fires work. If they do, produce any warm air, it's simply because they've warmed up your carpet and furniture around it from that radiant heat. The air's running over those objects and warming the air up a little bit.

So they call these like, a hotbox fire. They were around 20% heat efficient. So 80% of that heat is actually being used in the burner itself and going straight up the flu. So you're getting 20% of the heat that’s radian heat only - any warm air it might, it produces getting sucked straight back up your chimney, because chimneys are always drawing.

So that's why the old type are not very efficient and nowadays not being very efficient, isn't a good thing. So that's brought gas-fired manufacturers onto making them as efficient as they possibly can. So what they've actually achieved now, it's gone from 20% radiant heat, only with heat loss - up to anything up to 90/95%.
radiant heat with warm convected air and very little heat loss. And I'll show you how they achieve that with these fire next to me.
All right, so same size fire, what we call a 16 by 22 inch standard gas fire, obviously you probably see straight away that they have, a more pleasing fuel bed and more realistic.

This one happens to be a log one, but let's talk about why these are more efficient. The way these work in the same way with a burner underneath. Okay. With your controls. Gas coming through into that hot box environment, if you like, and that's kind of it, where they're similar.

How this produces heat is this has an air space around it and that air space goes over the exhaust outlets, which are pipes within the fire. So like any other radiator in your room, once this builds up heat, it naturally draws cold air towards it. So that cold air goes through the fire, through the bottom, here goes around the back of the fire, over the exhaust outlets, and comes through here as warm air.
