LA 35TBS

Air-to-water heat pump for outdoor installation. 35 kW heat output.

Uniquely environmentally friendly and energy efficient.

The LA 35TBS heat pump in monoblock design for flexible outdoor installation fulfils the legal requirements regarding sound and efficiency. Perfect for any building project, whether new build or existing building. With 35 kW building heat consumption, this air-to-water heat pump for outdoor installation is ideal for heating and rapid domestic hot water preparation. It heats living areas up to 750 sqm with a high flow temperature of 64 °C and is ideal for existing or new-build apartment blocks. The following also applies here: Flexible expansion options and compact design are included.

  • Compact with high performance class. With a footprint of just 77.5 x 106.5 cm, its space-saving design rivals any other heat pump. And this is combined with maximum heat output. The ideal solution for buildings with minimal outdoor space.
  • Intelligent design and extremely quiet. Effective reduction of low frequencies thanks to the flow-optimised casing. The matching weather protection cover provides increased sound reduction and operational reliability. Great side-effect: protection from strong wind loads or weather influences.
  • Convenient operation. The outdoor unit is operated conveniently and easily via the colour touch display on the wall-mounted controller. It can be mounted in any heated cellar or utility room.
  • Smart control. Using the Dimplex Home app (iOS/Android), you can access the heat pump control at any time and from anywhere. You can easily make the most important settings to the heat pump, such as summer/winter switching or setting the hot water temperature.
  • Intelligently networked. Optional connection to building management systems for monitoring the system operation is possible.
  • Efficient and demand-based. Demand-based regulation via two compressors in the refrigeration circuit – if only one is required, the other switches off. Verifiable efficiency thanks to certification measurement.
  • Eligible for subsidies. When old oil heating is replaced, the investment costs are subsidised by the state by BAFA, The Federal Office for Economic Affairs and Export Control. Up to 35%.
