Double sided E-Cosy Hampton 6.4kw

I installed this stove for a customer that was looking to be able to heat 2 rooms with one stove and this is a perfect stove for it that I actually have in my own home. I knocked through the two rooms where there was already a chimney in place.
Here is the stoves description:
The Defra Approved Ecosy+ Hampton 6.4 is one of the most up to date and cleanest double sided stoves sold in the UK. It is one of a very small number of double sided stoves that have been tested and approved to meet the new Ecodesign requirements, making this a stove for now and for the future. Passing this test and being one of only a few models on the market to do so shows the Hampton has been engineered and designed to a high standard by Ecosy+. All test results have been carried out by Kiwa Gastec in Cheltenham, UK - a leader in their field.
