Compass – Personal analysis & consultation
€250,00
€250 credited on an order from €2.000
5.000+ Satisfied customers
Product information
A 60-minute one-on-one consultation with a 21energy expert for people sitting on surplus energy — whether that's excess solar, biogas, an old heating system to replace, or just a rough idea worth exploring. You bring your energy data (or your assumptions), and they'll review your setup, give you an honest answer on whether Bitcoin mining hardware fits your case, and follow up with a full PDF report including a 60-month forecast and individual roadmap.
The €250 fee is credited back as store credit on any hardware order over €2,000 — so if you end up buying, the call is effectively free.
Best suited for: homeowners with PV systems, farms with biogas or large rooftops, businesses with their own power setup, and anyone wanting real numbers instead of a sales pitch.

The app (iOS) is well made and feels intuitive, the heater itself is very quiet even when running at its maximum power. I have using it for 5 days now and so far I'm very happy. I almost never write reviews but this company deserves to get recognition

Ofen 2 is good product and there is a good service support. The product is well designed and well manufactured. I got a minor bug issue at the beginning with the thermostat. Support solved it very quickly with an update.
