Modern steel boilers PK pellet. The fireplace is made of high-quality boiler steel 5 mm thick, which provides high resistance to temperature and corrosion. Its vertically set combustion chamber maximises and efficiently collect the ashes at the bottom of the boiler and thus easy to clean. For ecological combustion of pellets worry microprocessor control with LCD display in the integration of air-cooled torch, screw conveyor and hopper. The casing of the boiler is powder coated and effectively insulated with high-quality thermal insulation of glass wool high density. The boiler Valher PK fulfils the norms demands for Ecological Fund of the Republic of Slovenia.
