Product information

Description

The Alkotest TERMET KOCIOŁ 1/F GOLD PLUS II 25 (24,5)-2E-G20 is a floor-standing gas boiler designed for central heating systems in residential and small commercial buildings. With a nominal heating output of 25 (24.5) kW and two-stage burner operation, this unit is configured for natural gas (G20) at 20 mbar and provides steady heat delivery for radiators and underfloor heating circuits. The compact footprint and floor-mounted format make it suitable for plant rooms, basements, or utility spaces where a reliable gas-fired heat source is required.

Advantages

This boiler offers a clear two-stage control strategy that helps match heat output to demand, improving seasonal efficiency and reducing short cycling. The nominal power rating of 25 (24.5) kW makes it appropriate for medium-sized heating zones, and its construction is intended for continuous central heating operation. Designed for installation with standard natural gas supply pressure (20 mbar), the unit supports integration with conventional hydronic systems and circulation pumps.

Suitable for

  • Heating single-family homes and multi-zone apartments
  • Small commercial premises with moderate heat demand
  • Replacement of older floor-standing gas boilers in existing central heating systems
  • Integration with radiator and low-temperature underfloor heating circuits

Key specifications

  • Nominal heat output: 25 (24.5) kW
  • Fuel type: natural gas (G20)
  • Gas supply pressure: 20 mbar
  • Burner control: two-stage (2E)
  • Configuration: floor-standing boiler for central heating

How to use

Install the boiler on a level, non-combustible floor surface in a well-ventilated plant room following local gas and building regulations. Connect the gas supply, venting, water inlet and outlet, and the heating circuit according to the installation manual and national codes. Commission the unit by purging air from the heating system, setting the required flow temperature and burner control parameters, and verifying safe gas operation and combustion. Routine operation is controlled via the boiler’s built-in control interface; use two-stage settings to select lower or higher output to match heat demand.

Usage recommendations

To ensure reliable operation and maintain efficiency, arrange periodic professional servicing, check gas connections and flue integrity regularly, and use corrosion-inhibiting additives in closed heating circuits where recommended. For optimal comfort and energy use, combine the boiler with proper system thermostats, room sensors, and hydraulic balancing.
