Completely hidden within your existing fireplace and chimney. Nothing visible. Nothing compromised.

Check your eligibility A few short questions · No commitment required

Summers are getting hotter and period homes were never built for this.

01

Air conditioning units ruin rooms like yours

Ugly plastic units on original plasterwork.
Pipework boxed across period cornicing.
Portable units dragged from room to room.
The compromise has always felt wrong.

02

Installation has always meant damage

Drilling through original walls.
Weeks of disruption and repair.
Rooms perfected over decades, undone in days.

03

The fireplace has been redundant for years

Open fires are disappearing from cities - polluting, harmful to breathe, and increasingly banned. And the chimney that once defined the room sits completely empty.

Your fireplace looks beautiful. But the chimney behind it has been doing nothing for decades. Ruma routes a complete climate system through that existing cavity - delivering full heating, cooling and air purification, with nothing visible anywhere in your home.

The first installation is complete.
