plum - your partner in smart energy management

what
we do

We develop proprietary control systems for heat pumps, boilers, ventilation and underfloor heating,
as well as HEMS solutions for energy management in buildings.

As a technology pioneer in the gas and water utility sectors, we offer smart data loggers, volume converters and meters that leverage IoT technology while ensuring the highest levels of reliability.

two
business models

We develop and manufacture:

  • Fully customized OEM solutions for equipment manufacturers and distributors.
  • Proven, ready-to-install products under our own Plum brand.

We digitalize and automate processes to help our customers save money – both end users and companies integrating Plum products into their equipment and infrastructure.

We harness the potential of dynamic electricity tariffs and IoT technology to simplify the work of HVAC installers and reduce system operating costs.

We are building the infrastructure of tomorrow for the WATER and GAS sectors, delivering long-lasting devices backed by comprehensive technical support.
