Installer Boris Christo of HKM on quality, customer focus, and the future of energy from a single source

Christo offers an in-depth look into the company’s approach and its decision to partner closely with EcoFlow. For over 15 years, HKM has specialised in photovoltaics, electrical installations, and DGUV inspections. The company is considered one of the leading specialists in the Speyer region.

Christo sees EcoFlow as a true premium provider, distinguished by ease of installation, high product quality, modular expandability, and a well-designed, integrated system. The deliberate switch to EcoFlow in 2023 was driven by the goal of offering customers a future-proof, all-in-one energy solution. In a market that increasingly values efficiency, safety, and smart controls, HKM believes that EcoFlow clearly stands out.

According to HKM, EcoFlow impresses with: · Fast, hassle-free installation thanks to modular systems · Fully integrated components such as power storage, inverter, heating element, heat pump, and wall box · Expandability of battery storage even after years without technical barriers · A top-tier app offering intuitive control, visualisation, and energy management · Certified safety features, such as a fire protection valve in every battery · A unified system design: hardware and software from a single source

Despite market volatility, HKM has not experienced a decline in demand. In fact, the number of enquiries has continued to increase, particularly in 2025. The recipe for success: regional proximity, personal advice, honest prices, and tailor-made systems. Customers appreciate the combination of technical expertise and reliability. More than 160 EcoFlow systems were already installed in 2024.

A reliable partnership is essential for HKM, and that’s exactly what EcoFlow delivers. Boris Christo emphasises that support is rarely needed because the systems are extremely stable. However, if assistance is ever required, it is provided quickly and directly, with no waiting lines or call centres involved. This close connection with EcoFlow has existed since the beginning of the collaboration, enabling smooth communication. Out of the 160–170 systems installed in 2024, only two complaints were received: one relating to a battery and one relating to an inverter fan. Both issues were resolved swiftly and without complications. Customers especially appreciate HKM’s local presence, the high quality of the installed systems, and the well-integrated EcoFlow Ecosystem. PV, battery storage, heat pump, smart immersion heater, wallbox, PowerInsight — all from one provider and fully controllable via a single, intuitive app. Christo compares the concept to Apple or Tesla: the hardware and software are perfectly synchronised. Rather than cobbling together components, EcoFlow offers a complete intelligent energy system for electricity, heat, and mobility that is simple, reliable, and efficient. For HKM, that’s the key to customer satisfaction.
