What are the differences between Conventional Stoves and Modern Stoves?

Wood-burning stoves, like any piece of engineering that has been in existence for more than 100 years, have gone through considerable changes since they were first introduced.

Since the heritage and tradition of stoves is one of the factors that makes them so popular, the appearance of wood burners has remained relatively unchanged over the years. But it would be wrong to assume that they are still the same inside. Appearances can be deceptive.

Behind the exterior, the modern stove has changed almost beyond recognition. And that’s good news for the environment and for your bank balance.

Originally, stoves were very basic metal boxes in which you could build a fire. No consideration was given to ensuring that the wood burned cleanly or efficiently. That approach has changed fundamentally in recent years.


A good reason to be baffled

One of the key changes is that modern stoves contain a baffle. This is a metal surface that restricts the flow of air up the chimney and also reflects heat back into the firebox, increasing the temperature of the stove.

Newer stoves also have a secondary air input. This creates a supply of pre-heated air at the top of the firebox, which helps to burn gases that would have previously gone up the chimney.

Both of these innovations help to ensure that anything that can be burned is burned before it leaves the firebox.


Rising efficiency

In a conventional stove, the smoke and heat that rose out of the wood would continue to rise, straight up the chimney. That meant that gases that are harmful to the environment when unburned, but very useful for heating your home, were just allowed to escape.

And not all of them would escape. Some would stick to the side of your chimney in the form of creosote, causing your stove to be less efficient and more susceptible to chimney fires.

The new technology in use in modern stoves makes them 30% more efficient. That means almost a one-third reduction in the number of times you need to buy or chop wood. There is also a 90% reduction in air pollution from a modern stove in comparison to a conventional stove.

This is neatly illustrated by the lack of smoke that comes from the chimney of a modern stove – a nice symbol of a clean, efficient burn.

@ Ronald Ellis Hi Ronald Can you just clarify your question please? Thanks, Gr8Fires

Can you a diagram of as installed in stoves to make them clean burn with clean glass

@ Sue Goodchild Hi Sue, This depends if you are going up the chimney or out through a roof.
Scenario 1-: Going through a roof Using Single wall flue you can go up to a max of 1.8m from the
stove and then twin wall flue will be required which can be taken through the roof and used
externally. Neither of these can be cut. Scenario 2-: Going up a chimney If your stove is in a
fireplace chamber, you can use single wall flue up to a maximum of 1.8m and then use flexible flue
liner up your chimney which can be cut to size be your approved stove installer. You can view the
flexible flue liner kits here which includes all the components required-
https://www.gr8fires.co.uk/flues/flexible-flue-liner/flexi-flue-liner-kits Whichever way you
choose, we offer a 14-day money back guarantee, so if you have single or twin wall that is unused,
this can returned to us. Always use a competent Hetas or OFTEC qualified stove
installer. Thanks, Gr8Fires

Hi Adam, I now know which heater I want, but am unsure of height of flu. Can they be cut down to
size if they are to big. We calculate we would need 30m going by room heights and roof. Also do the
packs come with plates to block bottom of chimney off.

@ Alan Stewart Hi Alan, It is possible, but it would be an expensive job. It could most easily be
achieved by adding a thermal store to your property, then linking it to the various components of
the heating system. An alternative would be to disconnect your radiators from the sealed system and
heat them using the boiler stove, leaving your central heating to provide hot
water. Thanks, Gr8Fires

Is there a way that I can link a woodburner with boiler into a sealed heating system with combi
boiler?


Gr8Fires 2015-09-09 09:06:38
@david hooper. Hi David, Yes, it has a secondary air supply that both encourages flammable gases to
burn near the top of the firebox and directs air over the glass to help keep it clean.

Hi Tim, We certainly do - you'll find lots of options in our boiler stove section:
https://www.gr8fires.co.uk/stoves/boiler-stoves Give us a call if you have any questions. Many
thanks, Gr8Fires

Hi, Do you supply clean burn stoves with a back burner?

Gr8Fires.co.uk 2013-11-21 13:11:12
You're most welcome!
