Morco 11 Litre EUP Room Sealed Water Heater
The Morco EUP11RS is a high-performance, room-sealed instant water heater specifically engineered for the demands of boats, catering trailers, glamping units, and shepherd’s huts. This advanced model delivers a reliable flow rate of 8 litres per minute at a 35-degree temperature rise, providing a consistent hot water supply for showers and galleys in off-grid environments. Designed for installation flexibility, it supports both horizontal and vertical flue configurations to accommodate diverse cabin layouts. To maintain optimal performance and the required gas offtake rates, this unit must be supplied by a minimum 19kg propane LPG cylinder.
