Rank #2 in Best Wood Burning Stove 2026: Five Kilowatts, Eighty Square Metres
NRG Portable Defra 5KW Eco Design Stove, Cast Iron
Price and rating as shown on Amazon when we collected them. Both change.
The NRG 5KW Defra stove costs £255.99 and is rated 4.5 stars from 65 ratings, with a stated output of 5 kilowatts and a claimed coverage of 80 square metres.
It takes second because it states both numbers on one page and they cannot both be right: five kilowatts heats about 26 square metres by the trade rule, not eighty, and its model number is a UUID.
How those 65 ratings break down
An average hides its own shape. This is the spread behind the 4.5 stars.
