D.3. ELECTRIC HEATING ELEMENT FOR DHW AFTERHEATING
Description
It is used for hot water heating when the boiler is extinguished
and the hot water supply is depleted. If DHW is heated by a
boiler, the built-in thermostat switches off the heating element.
Heating elements are available in various designs and outputs,
the current assortment can be found on our website: https://www.
regulus.eu/en/ett-g-6-4-for-hw-storage-tanks-and-thermal-
stores.
The recommended model is ETT M that is equipped with an
integrated adjustable and safety thermostat and a power cord
w. el. plug.
Intended for variants
1 (options A, B)
2
Installation
Into the E1 connection of a hot water storage tank or a DUO/
HSK combination thermal store.
Settings in controller
The heating element is not controlled by the controller so it does
not require any settings in the controller.
The desired temperature is set by the thermostat knob on the
heating element.
Connecting terminals
The heating element does not connect to the controller terminals.
El. wiring
The ETT M heating element is equipped with a power cord with
el. plug.
Thus no professional electrician is needed for wiring.
TIP 1:
If you use a combination thermal store (variant 1 A, B) and a heating element for
heating system water, this heating element can be used also for DHW heating under certain
conditions. More information in Chapter D.4. Electric Heating Element for Space Heating, TIP 1.
TIP 2:
For DHW heating also other heating elements from our offer can be used that are
equipped with an adjustable and a safety thermostat.
Ripple control, single-phase or 3-phase wiring can be also used, as well as heating elements
of a higher output. However, those require installation by a professional electrician.
