An ATAG combi boiler fitted in a kitchen cupboard
An ATAG i28C combi fitted inside a kitchen cupboard, with the flue straight out through the back wall and new copper pipework above it.

The finished boiler inside the cupboard, ready for the doors to close over it.
This combi went into a kitchen cupboard, where the cupboard doors close over it and it disappears among the units. That only works if everything fits in the space: the boiler itself, the flue, and the pipework and valves. Here the flue turns straight back through the wall behind, and the copper is run neatly across a backboard at the top of the cupboard, with isolation valves and a system filter on it.
What we did
- ATAG i28C combi boiler fitted inside a kitchen cupboard
- Flue taken out through the back wall of the cupboard
- New copper pipework run across a backboard
- Isolation valves on the pipework
- System filter on the heating pipework
- Commissioned and tested by a Gas Safe registered engineer
A boiler you can shut the door on
Most people would rather not look at their boiler. Putting it inside a kitchen cupboard means the doors close over it and it sits in line with the rest of the units. The catch is that a cupboard is a tight space, so the flue route and the pipework have to be planned before anything goes on the wall.
Here the flue elbow comes off the top of the boiler and goes straight back through the wall behind, so nothing runs across the cupboard or out through the ceiling.
Pipework you can work on later
The pipework above the boiler is new copper, run neatly across a backboard, with isolation valves on it. Those valves are what let the boiler be serviced or repaired later without draining the whole system, and putting them where they can be reached with the cupboard door open saves time on every visit after this one.
There is also a system filter on the heating pipework. It catches the sludge that builds up in any heating system before it can reach the boiler.
