EHS Primus 12000S 12KW Electric System Boiler
The EHS Primus 12000S is a 12kW single phase electric system boiler designed to replace a gas system boiler, providing central heating via existing radiators or underfloor heating without altering the pipework.
When used with an unvented indirect cylinder, it also delivers mains‑pressure hot water, with the option to heat the store on off‑peak electricity for lower running costs.
Key Features
- 12 kW single phase output for small to medium domestic properties using a wet central heating or UFH system.
- Integrated pump and expansion vessel for a compact, self‑contained system boiler package.
- Pre‑wired chassis to simplify installation and reduce onsite wiring time for installers.
- No flue or gas supply required, eliminating combustion risks and flue routing constraints.
- Touch‑screen user interface providing clear temperature and mode control at the boiler.
How It Fits Your System
- Connects to existing radiator or underfloor heating circuits in place of a gas system boiler, using the same flow and return pipework.
- Designed to work with an unvented indirect cylinder to provide domestic hot water for multi‑bathroom homes.
- Can be paired with external timers or smart stats to heat the cylinder during cheaper night‑rate or off‑peak periods.
