Technical documents
Is it right for you?
Deciding whether ACR T550 ECO Cassette Stove fits the brief
The T550 ECO suits rooms with a wider fireplace opening where you want a broad, landscape flame picture set into the wall. It is the cassette to choose when the opening is 18 inch rather than 16, and the wide firebox is the reason to fit it.
It works well where a freestanding stove would be too much in the room but you still want a generous fire and the flexibility of burning smokeless fuel.
Before quotation
What to settle before specifying ACR T550 ECO Cassette Stove
The T550 ECO is a cassette, so like the T400 it needs a constructional hearth running above 100 degrees, and we check what is beneath the opening on the survey. The wider firebox means we confirm the 18 inch opening and side clearances carefully. We agree the frame choice, flue route and, in smoke control areas, the DEFRA position for your address.
An honest steer
How it compares with similar models
Choose the T550 ECO over the T400 ECO when you have the wider 18 inch opening and want the landscape flame picture and 40cm logs. Both are 5kW, so the difference is the width of the fire and the size of opening, not heat. The T550 also carries an A+ rating.
If you want a black glass front instead of a framed one, the T550 ECO BG is the same stove with a black glass fascia.
Fitting it locally
Fitting the ACR T550 ECO Cassette Stove in West Midlands homes
A good fit for the larger period fireplaces around Lichfield, Stafford and Sutton Coldfield where the opening is wide enough for a landscape cassette. We confirm the 18 inch opening and the constructional hearth on the survey before recommending it.
Common questions
Questions to check about ACR T550 ECO Cassette Stove
What is the difference between the T550 ECO and the T400 ECO?
The T550 is the wider cassette for an 18 inch opening and takes 40cm logs, with an A+ rating. The T400 is for a 16 inch opening and takes 25cm logs. Both are 5kW, so it comes down to the size of your opening and how wide you want the fire.
Does the T550 ECO need a constructional hearth?
Yes. Like all the ACR cassettes it runs a hearth above 100 degrees, so it needs a constructional hearth rather than a thin decorative one. We check what is under your opening on the survey.
Can I choose the frame?
Yes, it comes with a choice of three or four-sided frame. We help you pick the one that suits your fireplace on the survey or in the showroom.
How much is the T550 ECO fitted?
We price it after a showroom visit or free home survey so the quote covers the stove, frame and your opening. Visit us in Lichfield or book a survey.
