Its strength lies in its compact size, multifunctionality, and impressive performance.

Thanks to its ultra-quiet, fully automatic operation and high-efficiency performance, the Smart-Line is an excellent choice for a wide variety of mobile and marine applications. From small and large motorboats and sailing yachts to camper vans, holiday homes, horse vans, and flower transport lorries — this unit ensures reliable warmth in any setting.

The boiler is designed for both temporary and permanent occupancy and can be integrated with radiators, convector heaters, underfloor heating, air-conditioning systems, and Post Marine Heating’s own hot air system. The Smart-Line supports multiple heating configurations, making it a highly adaptable solution for creating a warm, cosy atmosphere on board or on the move.
