Every question on its own page, answered in the first line
48 questions, one page each, with the answer in the opening sentence rather than after four paragraphs of preamble. Where the honest answer is that the published figure was taken on a test bench your chimney will never reproduce, the page names those conditions and goes no further.
Choosing
Which appliance answers the need at all, when the cheapest option in a family is the right one, and what a single room does not need.
Sizing & output
Why a heatable volume in cubic metres is an assumption rather than a measurement, and what the rated output in kilowatts actually constrains.
Flue & draught
What a flue has to do before an appliance can work, what each bend costs, and why the same stove behaves differently on two chimneys.
Installation
Where the clearances come from, what a heat shield buys back, and which parts of the job are not decided by the buyer.
Fuel & moisture
What moisture content does to the heat you get, how long seasoning really takes, and which species are worth the difference.
Pellets & quality
What a pellet certificate fixes, what ash content changes week to week, and why two certified sacks still burn differently.
Lighting & burning
Lighting from the top, setting the air, and why running a stove slow is what glazes a flue.
Cleaning & sweeping
What a sweep removes, what a chemical cleaner does and does not replace, and which brush may go down which flue.
Wear & spares
The one part per family that goes first, whether a spare exists for it, and which appliances were built to be repaired.
Emissions & rules
What an emission stage measures, what an efficiency figure is quoted at, and where the rules come from in each country.
Safety & CO
What a carbon monoxide alarm does, what its stated lifespan means, and which symptoms point at the flue rather than the fire.
Splitting & storing
Tonnage against log length, the volume units firewood is sold in, and how a stack has to stand to dry.
Running costs
What a kilowatt-hour of wood, briquette and pellet actually costs, and which figures have to be converted before they compare.
