Construction
LK Electric Boiler -11, is a wall mountable and is
primarily designed for low-temperature heating
systems, e.g. under floor heating.
The boiler has the following features:
• Expansion vessel
• Safety valve
• Automatic air-bleeding valve
• Filling/drainage valve
• Overflow valve (safety valve device to pre-
vent overheating; if low flow rates it activa-
tes maximum safe temperature protection).
• Circulation pump, Grundfos UPM3 15-40
• Enclosure concealing pipe connections
LK Electric Boiler -11, is for space heating only,
not hot (washing) water.
Operation / Requirements
• Electronic temperature regulation with seven
settings from 1,6 kW to 11 kW.
The boiler is equipped with outside tem-
perature (weather) compensation, for auto-
matic control of internal temperature and
power output.
Other functions included in the electronic
controls:
• User selection of heating output at gradients
of 4-7.
• Overheating (maximum safe temperature)
safety function, this immediately shuts
down the boiler.
• Boiler temperature sensor and monitor.
• Status indication - indicating operational
status or malfunction.
• Input for external switching, e.g. room ther-
mostat.
• Input for remote control, incl. frost protec-
tion 10–20 °C.
• Circulation pump relay.
Sized for Kitchen Cabinets
LK Electric Boiler -11, can be wall hung or hidden
in a cupboard.
Its dimensions (WxHxD) are 546 x 601 x 180 mm,
so it can be mounted in most kitchen cabinets.
