Description
The RM Stelflow 180L High Gain Indirect Cylinder (TRSMVH-0180LFB) is a high-performance indirect hot-water storage cylinder engineered for fast heat-up and efficient heat transfer. Designed for larger domestic and light‑commercial systems, it pairs a high-output stainless‑steel coil with dense PU insulation to deliver reliable, on‑demand hot water while minimising standby losses. Its robust LDX 2101 construction and coated mild‑steel casing make it suitable for plant rooms and installations that require durable, long‑lasting performance.
Key Features
- Capacity: 168 litres actual usable hot water.
- High‑gain coil: single 316L stainless‑steel coil rated 25.2 kW for rapid heat-up.
- Large coil surface: 2.0 m² coil area to maximise heat transfer from primary circuit.
- Low primary resistance: 0.08 bar coil resistance for efficient flow and reduced pump load.
- High primary limit: coil max primary pressure 6 bar.
- Thermal insulation: dense PU foam (50 mm) to reduce standby losses (1.392 kWh/24h).
- Cylinder material: LDX 2101 for structural strength and corrosion resistance.
- Outer casing: coated mild steel for a neat, durable finish.
- Immersion heater: single 3 kW auxiliary immersion.
- Pressure & temperature ratings: max mains water pressure 10 bar; operating pressure 7 bar; operating temperature 60°C; safety valve temp 90°C.
- Standards & warranty: tested to BS EN 12897:2016; 25‑year warranty.
- Handling weight: 44.4 kg empty; 212.1 kg full.
Ideal Use Cases
- Larger homes and multi‑bath properties requiring fast replenishment of hot water.
- Systems where rapid heat-up from a primary heat source (boiler or heat pump) is needed.
- Installations with higher primary circuit pressures (up to 6 bar).
- New builds and renovations focused on performance and low running costs.
- Light‑commercial sites (guesthouses, small offices) needing reliable hot‑water delivery.
