Tap Water Unit
LK 250 TapWater Unit
• Easy to install - Plug-and-Play
• Scald protection with LK 551 HydroMix
• Available with anti-limestone coated heat
exchanger.
The LK 250 TapWater Unit is a device for heating tap water.
LK 250 TapWater Unit P has an electronic controller unit that
regulates the desired tap water temperature and at the same
time regulates the inlet temperature to the plate heat exchanger
to protect it from limestone.
The LK 250 TapWater Unit P consists of a plate heat exchanger, cir-
culation pump, flow sensor, safety valve and an electronic controller.
The temperature of the tap water can be adjusted between 40
and 65 °C. The circulation pump only runs when hot water is
required, which reduces energy consumption.
LK 250 TapWater Unit
Unlike the LK 250 TapWater Unit P, this unit has a thermic
mixing valve which, instead of an electronic controller, regulates
the tap water temperature and at the same time regulates the
inlet temperature to the plate heat exchanger to protect it from
limescale deposits.
The LK 250 TapWater Unit consists of a plate heat exchanger,
circulation pump, flow sensor, safety valve and a mixing valve.
The temperature of the tap water can be adjusted between 35
and 65°C. The circulation pump only runs when tap water is
needed, which reduces energy consumption.
When choosing a tap water unit, it is important to know the
water quality in the area where the unit will be installed.
A hot water circulation kit is available as an accessory used
to maintain the intended hot water temperature in the entire
domestic hot water system, which is particularly suitable in
buildings where a tap point is located some distance away.
