The Atmos P series is eligible for funding without a particle separator starting at 25 kW. Lower-performance boilers only meet the requirements with a particle separator.

For this reason, we only offer eligible options online.

If you choose the variant without particle separator for the 14-21 kW boilers, or if you additionally prefer the particle separator for the P25 variant, please contact us and we will prepare an individual offer for you.
