The Mini is a 5 litre point of use water heater, with an impressive 6 minute heat-up time. The small size makes the Mini ideal for under sink fitting in office buikdings etc where the central hot water supply is located at a distance. The Mini RM5 should be installed horizontally, and has a factory fitted thermostat adjustable 30-60 degrees C.
The OSO MINI RM5 is perfect for point of use "under sink" water heater. The 3kW element will heat the 5 litre capacity from cold in less than 6 minutes. The unit will be most efficient when fitted horizontally with the connections facing upwards. Wall mounting brackets are provided with the cylinder.
Although the RM5 is an unvented cylinder, it requires no expansion vessel, although an expansion relief valve for connection to a waste pipe is supplied. Domestic water expansion is accommodated safely and legally within the cylinder and associated pipework.
No check valve should be fitted within 2m of the RM5, to avoid the need for an expansion vessel.
Temperature control is achieved through a factory fitted adjustable thermostat, with an additional overheat safety cut out. An electrical cable is supplied factory fitted to the cylinder for connection to the mains supply.
