Heta inspire 45 multifuel

Jack26

Hi I new to Multifuel stoves. I’ve been doing a little research and a few people say not to put smokeless coal into my Heta Inspire 45. I’m just wondering why? It’s classed as a multi fuel burner. Should I just stick to logs ? Thanks Jack 👍🏻

The reviews in "What Stove?" by owners suggest that the multi-fuel moniker is misleading. It is.


If you look at the data sheet on the manufacturer's web site you'll see no mention of solid fuel in the sense that British people understand it.

A case of lost in translation, probably.

Thanks davesnave I am new to this as it’s my first stove I have been burning smokeless coal just not a lot. What is the need for a grate then if it’s only a log burner? Will it do any harm burning smokeless coal? Thanks Jack

Coal requires air to be fed from the base of the fire. Burning wood, the air comes in from above. For a coal fire, the grate bars are often much thicker & heavier than in wood stoves.

The instruction manual specifically states that the stove "is EN approved for firing with wood fuel. You must therefore only burn clean, dry wood in your stove". Whilst you could burn smokeless coal in the stove, it would probably invalidate your guarantee. It may well also shorten the live of your flue liner unless it is rated for use with coal.

Two years on, I've been burning wood and coal in my stove, but it is designed to burn both. Most people advise against burning wood & coal at the same time, but I ignore them

The makers advise not to burn coal, so why would I contradict them?


I only know about my wood burner in detail. The grate on that exists because it can burn smokeless fuel, but it's also an aid to ash emptying. While in woodburning mode the grate can be clsed completely, but it can be opened temporarily to release the ash.

I'm guessing that the grate may not be adequate to burn smokeless fuels which as davesnave says is designed to tke air from below and burns a lot hotter than wood.

The grate on my multifuel has a blanking plate to reduce the airflow for when it's burning wood and a very substantial cast grate for when solid fuel is being used although I've never tried it.

As dave says you could invalidate your guarantee and possibly burn out or distort the grate in your woodburning stove especially of the grate is stell plate rather than cast. You burn solid fuel at your own risk.

Thanks for the replies I decided to give Heta.dk an email. Wasn’t sure weather i would get a reply but i did here is the message.
“Hello Jack

Thank you for your inquiry. The inspire 45 is a multi-fuel stove, so yes you can burn smokeless coal in it.
We have tested burning Homefire Ecoal 50 in our Inspire range. It performed very well.
I would suggest of course to be careful of over firing/fueling, this can stress the appliance.

When we burn the smokeless fuel, we first start a wood fire and when it is ready for re-fueling we set the coal over the wood embers.
Turn the air up to wide open until the coal is ignited.
Once this occurs back the air down to the desired burn keeping in mind not over firing.
On the bottom right there is a control to the ash grate, it is best this is pulled out to an open position.

It is important to follow the fuels manufacturer suggested fuel load for desired Kw stove.”

Why they only say wood I do not know. I thought I would let people know as it’s been bothering me for the whole weekend lol
Thanks jack
