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 to generate steam or hot water used for heating your home or business . Boilers can be powered by various fuels, including natural gas, propane, oil, or electricity. .

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. . This results in lower energy bills and reduced greenhouse gas emissions.

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 both a hot water storage tank and a cold water feed tank. This system is ideal for larger homes

BTU (British Thermal Unit)

A BTU is a measurement of thermal energy. It's used to express the heating capacity of a boiler. A higher BTU rating indicates a more powerful boiler. . Choosing the correct BTU rating is important for efficient and cost-effective heating.

AFUE (Annual Fuel Utilization Efficiency)

AFUE measures how effectively a boiler converts fuel to heat. 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 water to radiators or underfloor heating systems.

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.

Thermostat

A thermostat is a temperature control unit in your property. Thermostats can be programmed to maintain different temperatures at different times of the day, helping to save energy.

Flue

A flue is a duct or pipe that carries combustion byproducts outside. Proper venting is essential for the safe operation of any boiler.

Heating Engineer

A heating engineer, or boiler installer, is a certified technician who specializes in installing, repairing, and maintaining boiler systems.

Radiator

A radiator is a heating device designed to transfer thermal energy from one medium to another from the hot water or steam circulated by the boiler to the air in a room.

Zone Valve

A zone valve controls water flow It enables customized temperature settings. They can significantly reduce energy usage.

What is a boiler’s AFUE rating?

AFUE stands for Annual Fuel Utilization Efficiency. measures a boiler's overall energy efficiency. It's expressed as a percentage. For example, higher AFUE ratings indicate higher efficiency, resulting in less wasted fuel and money. The minimum AFUE for new boilers is typically 80%, but higher-efficiency models are available with AFUE ratings exceeding 95%. Look for a high AFUE rating when shopping for a new boiler.
