Ruma Climate — London
Ruma delivers hidden heating, cooling and air purification through the architecture your home already has — using your disused fireplace and chimney cavity, with nothing visible anywhere in the room.
The Invention
Your fireplace looks beautiful. But the chimney behind it has been doing nothing for decades. Ruma routes a patent-pending HVAC system through that existing cavity — delivering full heating, cooling and air purification — with nothing visible anywhere in your home.
Demand for home climate control in the UK has never been higher. But if you own a Georgian, Victorian or Edwardian property, your options are painfully limited — and every one of them asks you to compromise the home you love.
Wall-mounted air con units are ugly, obvious, and completely at odds with original architecture. No amount of clever placement makes a plastic box on a period wall acceptable.
Conventional HVAC means weeks of disruption, drilling through original walls, cutting across cornicing, and boxing in pipework — followed by the cost and chaos of making good. Rooms that took decades to perfect, undone in days.
Gas boilers face increasing regulation and rising costs. Period homeowners need a modern alternative — one that heats, cools and purifies without ripping out what's already there. Ruma is designed to be solar-ready, supporting the shift to cleaner energy on your terms.
Your chimney has run floor to ceiling for over a century — a vertical cavity through the heart of the building. Ruma routes a complete climate system through it. No new holes. No visible components. The room stays exactly as it should be.
Refrigerant pipework and services route through the existing chimney cavity — the same structure that's served your home for generations. No new ducting, no drilling through original fabric.
The system is concealed within the fireplace opening. No wall units, no exposed pipework, no compromise to original plasterwork or cornicing. Every room looks untouched — because it is.
A complete year-round climate system — warm in winter, cool in summer, with optional air purification — running quietly and efficiently through the architecture your home already has.
Who It's For
