about plum

We are a manufacturer of industrial electronics, including controllers for heat pumps, boiler controllers, ventilation and underfloor heating controllers, sensors, gas volume converters, gas flow recorders, and other measurement devices. Our mission is to provide comprehensive electronics solutions and, in turn, support the growth of your business. We deliver fully customized OEM solutions tailored to equipment manufacturers and distributors. We focus on the HVAC, Gas and Water and Sewage markets. We emphasize cooperation, business partnerships, and personalized product development, both in terms of design and programming. This is our promise and competitive advantage.

We create OEM system solutions. However, we treat each product and its implementation individually. We guarantee full implementation and after-sales support from our R&D department.

We are agile! In our work, we follow the principles of agile project management, allowing us to implement our devices faster and more effectively.

We manufacture in Poland. We ensure product delivery reliability through local production, which is fully quality-controlled.

We design competitive and interoperable devices, meaning they can collaborate with products from other suppliers.


For almost 40 years, PLUM has been providing solutions for effective telemetry in the gas industry, network monitoring, and efficient billing in the water and sewage industry. PLUM also offers solutions for the HVAC industry, including heat pump controllers, recuperation controllers, underfloor heating controllers, as well as related Home Energy Management Systems (HEMS) and intelligent remote heating system management in homes.
