Quality components

Quality components

The quality of the components within Grant oil-fired boilers is never compromised. Within each boiler is the latest burner technology, burners which have undergone significant advances in design in recent years. Developed to atomise oil as efficiently as possible, modern day pressure jet burners achieve excellent combustion efficiencies. In addition, these burners are all low NOx, delivering high performances with lower emissions levels.
