EHC SlimJim Electric Flow Boiler 12kW
Product Description
The EHC SlimJim 12kW Electric Flow Boiler is a compact, fully-electric boiler designed for efficient wet central heating where installation space is at a premium.

- Runs quietly, with no moving combustion parts
- Simple user interface with temperature control dial (30°C–80°C)
- Front-mounted heat/fault diagnostic indicators
- Stainless steel, insulated heat exchanger for energy retention
- Run-Dry water level sensor prevents overheating in case of water loss
- Built-in high current thermal cut-out for safety
- No mandatory annual servicing required
