Types of Commercial Gas Appliances
The main types of commercial gas appliances — boilers, burners, warm air and radiant heaters, catering equipment, water heaters and CHP — and what each needs from the installation.
Commercial gas appliances range from a single 30 kW water heater in a café to multi-megawatt forced-draught burners in an energy centre. Each family has its own installation standard, ventilation and flue requirements and certification, and each needs a different competence category to work on.
These guides describe the main appliance types we install and maintain across London, how they work and what to look for when choosing, servicing or certifying them.
