Bare wire technology = longer product life and better sustained performance even in hard water areas.
All of Stiebel Eltron’s 3 phase and most of our single phase instantaneous water heaters feature cutting edge bare wire technology.
Bare wire the benefits:
- Faster heat up time
- Can take pre-heated water
- Resistant to limescale = better sustained performance and longer product life
- Faster to react to changes in water pressure and voltage to maintain constant water temperatures
- More efficient
Bare wire heating element – how it works:
The live heating conductors are located directly in the water being heated. The bare wire heater spirals are set into an insulating block that is encased by a pressure-tested cylinder.
Pipes in the insulating block house the heater spirals. The insulation resistance is assured by pre- and post-ballasts. The insulation resistance depends in part on the properties of the water flowing through. To ensure safe operation, the electrical resistance or conductivity of the water at the place of installation must be takeninto consideration.
Bare wire heating elements are also especially suitable for use in hard water. The very small amount of water inside the appliance and the low-mass heating system mean there is hardly any post-heating after the appliance has been switched off – a major reason for the reduction in scale build-up
