Today, RKV Cleantech came to fix a problem with our heat pump. The house wouldn't heat up during the cold weather, and the heat pump kept malfunctioning. RKV Cleantech fixed the problem and left everything neat and tidy. The outdoor unit also had significant damage to the pipe insulation caused by birds (magpies). This was repaired, and the whole thing looks much better than it ever did. Most importantly: the heating works like new again, and the technician was exceptionally friendly and helpful!

To make my home more sustainable, I started looking for an installer. I ended up with RKV Cleantech because they were great at brainstorming and advising on the possibilities. They've since installed an Intergas XTEND heat pump, a Toshiba Haori air conditioner, and a Toshiba Seiya air conditioner. Everything was installed neatly and professionally. And tidied up again. Now I need to spend some time monitoring my energy consumption and then find a suitable Enphase battery pack. That will probably be my next project. I recently had RKV Cleantech from Emmen install an Enphase home battery system with System Controller, including an Enphase charging station that's bidirectional. Everything is neat and tidy and works as it should. For the battery system with an off-grid cabinet, they installed two conduits from the crawl space to the shed. They also rearranged my meter cupboard and figured out exactly how the electrical wiring runs to the shed. That also gave me more insight and confidence in the whole process. This wasn't the first time I'd worked with them. They previously installed a hybrid heat pump and two air conditioners for us. Everything was also done well and as agreed. What's important to me is that RKV Cleantech is an Enphase Energy platinum installer. You can tell they really understand Enphase systems and home batteries in general. They know what they're doing and can explain everything clearly. All in all, a reliable company that works efficiently and keeps its promises. I can definitely recommend them.

Thank you so much for your initial help, the very friendly staff. You fully investigated my system, repaired it, reset it to default values, explained everything thoroughly, checked both inside and out. The house is wonderfully warm and everything works as it should. I contacted several companies in the provinces of Groningen and Drenthe, but no one could help me with the Radson brand. I was left in the cold for a few days until I contacted RKV Cleantech. I was helped the next day. They are a company with extensive knowledge and are familiar with most brands of heat pumps, underfloor heating systems, solar panels, and energy technology, etc. You get complete peace of mind! I am very grateful; it doesn't get any better than this. Thanks! Louis Kakkatoma from Veendam

RKV recently visited us at our new business premises. The old meter box was expertly replaced with a new one. They also actively collaborated on the remaining electrical work, focusing on safety and future-proofing. We are very satisfied with their professional approach and craftsmanship. They are definitely a reliable partner to work with. Thanks, guys!
