Efficient flow technology.

The pressureless M-O small instantaneous water heater is ideally suited as an energy-saving replacement unit for conventional small accumulators combined with low-pressure fittings.

  • Hydraulically controlled instantaneous water heater (over-sink unit) in mini-format for the energy-efficient supply of a wash basin or utility sink
  • The full heating power switches on automatically as soon as water flows through the device
  • Efficient flow technology for optimum water jet with economical water consumption
  • IES® bare-wire heating system with replaceable heating cartridge ensures longer service life, less calcification and is efficient and easy to maintain
  • Removable type plate cover for access to the central cover screw and water quantity adjustment
  • Ready to plug in (3.5 kW) or mains cable (from 4.4 kW), length: 65 cm
  • Pressureless design, only suitable for low-pressure fittings
  • Jet regulator insert for mouthpiece M 22/24 on the fitting
  • Also available as complete sets with fitting: M / SMB
  • Dimensions (height × width × depth): 13.5 × 18.6 × 8.7 cm

CSP 3

CSP 3 (included)

Aerator insert for tap adapter M 22/24 at the tap. The aerator at the tap supports the energy- and water-saving operation of the compact instant water heater. The new special CSP aerators mix air into the water and thus create a uniform water stream that does not splatter but softly cascades down. CSP 3 (< 2 l/min).

CSP 3: Part no. 0010-00421

CSP 6

CSP 6 (included)

Aerator insert for tap adapter M 22/24 at the tap. The aerator at the tap supports the energy- and water-saving operation of the compact instant water heater.
