Horizontal Immersion Heater Element 240V 1kw 11"+Ht CutOut
Immersion heater designed for unvented hot water systems using hot water storage calorifers, as found in boats (includng canal boats), caravans, camper vans, horseboxes and chalets.
Allows production of hot water from a 240V shore line or hookup, or an on-board genset.The low power enables the heater to operate from the limited power supple available with many landline or shoreline hook ups in marinas and campsites. These heaters will typically be inserted across the diameter of the tank, low down, not placed in the top of the tank pointing downwards (such heaters generally being much longer length).
These immersion heaters have 'Incaloy 800 Elements and Dual Thermostats' which is a legal requirement on unvented systems. The first thermostat is the 'control' stat (adjustable), the second thermostat is a 'safety cut out' which turns off the heater in the event of the first one stat failing and causing boiling. If this second stat operates, it stays off and must be manually reset after the problem has been resolved.
Standard 2.1/4" BSP thread
Fits most calorifiers and many other domestic and leisure vehicle cylinders
It has been used in the water pump of my 1923 Aston Martin. However, I had to 'unwind it' into cord strips. I have found that keeping in it original form keeps it from drying out, ready for next time.
We have these fitted to our sliding doors on our Broom flybridge motor cruiser. They are fine when newly fitted but despite cleaning the tracks they run on if any dust or dirt gets on the track despite constant cleaning and lightly spraying with PTFE the travellers begin to break up. The plastic outer cover becomes slightly open at the ends and the roller bearings begin to fall out over time. To replace the whole system is extremely expensive so we unfortunately have to tolerate changing them periodically. We are constantly on the lookout for a more reliable system.
