Frequently Asked Questions

Inset or freestanding wood burner?

How deep does chimney need to be?

Most inset stoves: 350–500mm depth. Some shallower units (250mm) for tight installations. Survey before ordering.

Will an inset stove heat the room?

Yes — slightly less efficient than freestanding (some heat absorbed by chimney) but well-installed inset stove heats 30–50m² room.

Premium inset stove brands?

Stovax Riva (UK premium), Charnwood Cove 3 (Isle of Wight), Morsø S20 (Danish), Contura i7 (Swedish).

Aesthetic vs heat?

Inset stoves: more aesthetic, slightly less efficient heating. Freestanding: maximum heat output. Choose based on priority.

Cost comparison?

Inset stove install: £1,800–£4,000. Freestanding wood burner: £1,800–£4,500. Similar costs; choose based on aesthetic preference.
