Boiler Installation Glossary

Understanding key boiler terms can help you make informed decisions. Here's a helpful guide to boiler terminology:

Boiler

A boiler is a closed vessel where water is heated under pressure used for central heating or domestic use. Different fuel types are available.

Condensing Boiler

A condensing boiler is a more efficient type of boiler that extracts more heat from the fuel by condensing the water vapor in the exhaust gases. . It is an environmentally friendly way to heat your home.

Combi Boiler (Combination Boiler)

A combi boiler provides both heating and hot water, eliminating the need for separate systems or a hot water tank. It's a space-saving option, ideal for smaller properties.

System Boiler

A system boiler heats your central heating system directly and stores domestic hot water in a separate hot water cylinder.

Regular Boiler (Conventional Boiler)

A regular boiler, also known as a conventional or heat-only boiler, requires a separate cold water storage tank and a hot water cylinder. . It's the most traditional type of boiler and is suitable for properties with multiple bathrooms or high hot water demand.

BTU (British Thermal Unit)

A BTU is a measurement of thermal energy. It's used to express the heating capacity of a boiler. Bigger is not always better; a properly sized boiler ensures efficiency. A qualified heating engineer can calculate the BTU requirements for your space.

AFUE (Annual Fuel Utilization Efficiency)

AFUE measures the efficiency of a boiler A higher AFUE rating means the boiler is more efficient and wastes less fuel.. Efficient heating saves you money.

Expansion Tank

An expansion tank accommodates the expansion of water as it is heated. It prevents pressure buildup in the heating system and helps maintain safe operation. in modern boiler systems.

Circulator Pump

A circulator pump circulates hot water from the boiler throughout the heating system delivering warmth to the spaces you need. It's a key component in maintaining consistent temperatures.

Pressure Relief Valve

A pressure relief valve is a safety device that opens when pressure in the system exceeds safe levels. It is an essential safety component for any boiler system.

For example, an AFUE of 90% means that 90% of the fuel energy is converted into heat for your home, with only 10% wasted. . The minimum AFUE for new boilers is typically 80%, but higher-efficiency models are available with AFUE ratings exceeding 95%. Prioritize energy efficiency when choosing a boiler to reduce costs and your carbon footprint.
