Are there any eco fuels that are ok for asthma?

[YukoandHiro]

Thinking of installing a wood burner or stove but there's no gas supply to the fireplace so fitting a fakey gas version (cleaner, if not as classy) will probably be far more expensive due to routing the gas supply.
But I have a daughter with asthma and viral wheeze, so wouldn't ever burn wood in the house.
Are these new eco fuels eg brickettes made from coffee grounds ok/better for asthmatics? Or just the same? I can't seem to find any research on it.
I know that for ease I'd definitely rather gas but can't be bothered to go through the effort of lifting floorboards etc.

Bump

Multifuel stoves burn pretty clean, but there will still be smoke round the house, and dust leakage when you clean out the ash.

Definitely don't get an open fire, and definitely, definitely don't get a flueless fire ornament.

I am OK with briquettes but not with logs. I also don't sort out the fire/clear up the ashes.

However a lot depends on the individual, unfortunately there is no guarantee your DD will be OK.

Personally I'd get the gas fitted.

I burned smokeless fuel (city, open fire) without issues from asthma

Both my dc have asthma. We have an open fire and a wood burner (live in the back of beyond so gas isn't an option for us) no problems with asthma from our fires. Bonfires are an issue, as is a charcoal BBQ, or cooking outside on a fire pit (all trigger an asthma attack) we only burn well seasoned wood, no coal, no 'green' wood. Chimneys swept once a year, and I keep the grates scrupulously clean. The ash (once cold) is mixed into my compost heap, and used in the garden for my acid loving plants!
The only issue with the open fire is if a log rolls forwards and then we end up with a smokey room, but we're very careful with the open fire, and hope to replace with a wood burner soon.
