Description
The RM Stelflow 210L High Gain Slimline Indirect Cylinder (TRSMVH-0210SFC) is a compact, high‑performance indirect unvented hot water cylinder engineered for rapid heat‑up in space‑restricted installations. Built with a high‑output stainless‑steel coil and dense PU foam insulation, it delivers dependable on‑demand hot water for larger homes and light‑commercial sites while minimising standby losses and installation footprint.
Key Features
- Capacity: 185 litres actual usable hot water.
- Slimline design: space‑saving profile for cupboards and tight plant rooms.
- High‑gain coil: single 316L stainless‑steel heat exchanger rated 27.8 kW for very fast heat transfer.
- Large coil surface: 2.0 m² coil area to maximise heat exchange from the primary circuit.
- Low coil resistance: 0.03 bar to reduce pump load and improve flow efficiency.
- High primary limit: coil max primary pressure 6 bar.
- Robust construction: LDX 2101 cylinder material with coated mild steel outer casing.
- Thermal insulation: dense PU foam, 50 mm thickness, to reduce standby loss (heat loss 2.0 kWh/24h).
- Immersion heater: single 3 kW auxiliary immersion for electric boosting.
- Pressure & safety: max mains water pressure 10 bar; operating pressure 7 bar; safety valve temp 90°C.
- Standards & warranty: tested to BS EN 12897:2016 and backed by a 25‑year warranty.
Ideal Use Cases
- Larger homes and multi‑bath properties needing rapid replenishment of hot water in limited space.
- Installations where fast heat‑up from a boiler or heat pump is required.
- New builds and renovations replacing bulkier cylinders with a slim, high‑performance unit.
- Light‑commercial sites (guesthouses, small offices) requiring reliable on‑demand hot water.
- Systems with higher primary pressures or where low pump load and fast recovery are priorities.
