We have the answers.
Why choose hestiia® solutions instead of a conventional electric heater?
That's not the right comparison. hestiia® solutions don't replace a conventional electric heater — which wouldn't typically be selected for a new residential project anyway. They are chosen as an alternative to collective heating systems, offering individual heating that qualifies under RE2020.
The result: a simpler, more cost-effective solution to design, install, and operate.
Is it more complex to install than an electric heater?
No. Installation is standard (wall mounting and electrical connection). The only specific requirement is the RJ45 connection, which is fully documented and supported by hestiia®.
Does this change anything for the end user?
No. The radiator works just like a standard connected model, with the same comfort and settings. The computing component has no impact on noise, appearance, or the occupant's energy consumption.
When should the products be ordered during the project timeline?
Our radiators are made to order, with an 8-month lead time.
