PRO Series 15–35 kW – pellet and eco-pea coal boiler
How does the PRO series boiler work?
The highest efficiency in the MOCEK range
The PRO series boiler is the most powerful series in the MOCEK range, designed for buildings with higher heat demand. An advanced microprocessor controller automatically regulates pellet feed, ensuring high heating efficiency and stable operation even under heavy system load.
Output up to 35 kW — for larger homes and outbuildings
15, 20, 25 or 35 kW with side hopper
PRO is available in four output variants: 15, 20, 25 and 35 kW, making it a suitable solution for both large detached houses and buildings with a larger heated area, such as farms or commercial premises.
Class 5 and subsidy eligibility
Low emissions at high output
Despite their high output, PRO boilers meet the stringent requirements of Class 5 and Ecodesign, emitting significantly fewer pollutants than older designs. They are on the ZUM list, which opens the way to subsidies under the "Clean Air" programme.
PRO Series: One Boiler, Two Fuels
PRO is the most powerful MOCEK series (15–35 kW) and the only one available in two fuel versions on the same design: PRO Pellet with an external BatoryPell® burner and PRO Ekogroszek (eco-pea coal) with a cast-iron Batory retort burner. A boiler bought for eco-pea coal can be converted to pellets with an adaptation kit. In the PRO series, the hopper is always on the side.
| PRO Pellet | PRO Ekogroszek | |
|---|---|---|
| Burner | external BatoryPell® (pellet) | cast-iron Batory retort (eco-pea coal) |
| Controller | IRYD 620 Pellet with automatic ignition | IRYD RTZ PID (Fuzzy Logic) |
| Available outputs | 15, 20, 25, 35 kW | 15, 20, 25, 35 kW |
| Gross price | PLN 14,500 – 16,900 | PLN 12,000 – 14,200 |
| Subsidies | pellet boilers on the ZUM list – see subsidies | check the current rules of the programmes for eco-pea coal boilers |
| Fuel change | eco-pea coal → pellet adaptation kit, no need to replace the boiler | |
Who the PRO series is for
- Large homes of 150–350 m², farm buildings, workshops and small facilities – outputs of 25 and 35 kW, which are not available in the OXYPELL and BIOPAL series.
- People who want a choice of fuel depending on prices in a given season.
- Current eco-pea coal boiler users who plan to switch to pellets in stages – first a PRO Ekogroszek boiler, then the adaptation kit.
Which PRO output for which building
As a rough guide, with standard insulation: 15 kW – up to approx. 150 m², 20 kW – 150–200 m², 25 kW – 200–260 m², 35 kW – 260–350 m² or poorly insulated buildings. For exact sizing, use the boiler output calculator.
Frequently asked questions about the PRO series
Is the PRO available with a top-mounted hopper?
No – the PRO series is made only with a side hopper. The OXYPELL and BIOPAL series have a top hopper.
Can the PRO Ekogroszek be converted to pellet later?
Yes, with the conversion kit: a BatoryPell burner, an IRYD 620 controller, a hopper and a pellet feeder. The heating system plumbing stays unchanged.
Which controller and accessories are compatible with the PRO?
The room panels, internet module and sensors from the accessories shop are compatible with both PRO versions. Full price list for all series: MOCEK pellet boilers, and for eco-pea coal boilers: eco-pea coal boilers.
