Heta Inspire 40 Insert
Inspire 40 Insert is a compact built-in wood-burning appliance for a flush fireplace treatment. It keeps the fire behind a simple rectangular frame and can be considered where the available chimney breast does not lend itself to a large open chamber. The opening, construction and flue still need to be surveyed before the insert is specified.

Common questions
Questions to check about Heta Inspire 40 Insert
What is the difference between the flat and hidden frame?
The flat frame sits proud of the wall as a slim border; the hidden frame is plastered in so the glass appears to sit straight in the wall. Both finish the same firebox, and the choice is made when the order is placed.
Can the Inspire 40 Insert go into an existing chimney breast?
Often, yes. It needs a suitable builders opening and a lined flue, which is exactly what the home survey establishes before we quote.
