BOLDR

Boldr is a home-climate brand built around two connected products: Kelvin, an infrared heater, and Klima, a smart thermostat for air conditioners. Both are managed through the Boldr Energy app, which schedules heating and cooling room by room, monitors consumption in real time and predicts monthly bills.

The system detects open windows, adapts to outside weather and can join the Boldr Grid Connect programme, which shifts operation to off-peak tariffs; the company claims savings of 30% on energy use and up to 40% with grid optimisation. Products ship directly within 48 hours, and a separate Boldr Pro programme supplies HVAC contractors with tools and support. The company is registered as Baldr Group Ltd in London.
