Is it right for you?
Who the ACR T550 ECO BG Cassette Stove suits best
The T550 ECO BG is the largest and sleekest of the four cassettes: the 18 inch opening size with the contemporary black glass door. When the stove is off it reads as a clean dark rectangle in the wall; lit, it is a wide, uninterrupted window of flame. For modern renovations with a generous chimney breast it is the premium look of the cassette family.
From the survey
Installation notes for the ACR T550 ECO BG Cassette Stove
Fitting matches the standard T550: constructional hearth (checked on survey), 125mm flue, 18 inch opening, three or four sided frames. The black glass face rewards a considered chamber, and we often pair it with honed granite or large-format porcelain so the materials match its clean lines.
An honest steer
How it compares with similar models
Same price as the standard T550, so the black glass costs nothing extra and the choice is purely aesthetic. Against the T400 BG the 550 buys the wider opening, wider view and 40cm logs. If your room leans traditional, the standard doors suit better; if it leans modern, the BG pair are the obvious picks.

Common questions
ACR T550 ECO BG Cassette Stove FAQs
Does the black glass on the T550 BG cost more?
No. The BG and the standard T550 are the same price, so the choice between classic face and black glass is purely about which suits your room.
How wide is the view of the fire on the T550 BG?
The stove is 620mm wide overall in the 18 inch opening format, giving the widest flame picture of the ACR cassette family, kept clear in normal use by the airwash system.
Can the T550 BG go into a wall with no chimney?
A cassette needs a proper flue route, so in a home with no chimney it requires a purpose-built chamber and twin-wall flue, which is a bigger job than a chimney installation. We assess the options honestly on the survey.
What warranty comes with the T550 BG?
The full 10 year ACR warranty, the same cover as the rest of the ACR cassette and cast iron ranges. We handle the handover paperwork when we commission the stove.
