Pipe installation
Closed system
The electric flow heater is connected to a closed expansion
tank in an unbroken, uninterruptible connection to a type-
approved safety valve, DN15, with maximum 3 bar opening
pressure.
The flow / safety lines must always be equipped with
automatic venting. Otherwise, air can accumulate in the
boiler tank, which may cause damage to the immersion
heaters.
The discharge pipe from a safety valve must meet the
requirements under EN 12828.
Steam or liquid that flows out of the safety valve when it
opens must be drained safely.
The discharge pipe from the safety valve is dimensioned
so that the blow-off capacity is not impeded.
The discharge pipe must be laid so it cannot freeze, must be
cleaned well and must be laid so that water pockets cannot
form.
The opening pressure of the safety valve is
determined by the component in the system
that tolerates the lowest pressure.
System principles
The figures shown are system principles. The actual
system must be installed according to existing
standards. Any additional equipment must be installed
as indicated by the manufacturer for its product.
Radiator system
By supplementing the EK 15E with an outdoor temperature
sensor, an outdoor temperature compensated supply
temperature is obtained in a shunt-free system.

Underfloor heating system
By supplementing the EK 15E with an outdoor temperature
sensor, an outdoor temperature compensated supply
temperature is obtained in a shunt-free system.

With boiler
As a complement to an existing boiler, the EK 15E can
be installed either between hot water outlets if applicable,
on the electric flow heater, or between the electric flow
heater's expansion pipe and drain valve.
