Boiler Installation Glossary

Understanding key boiler terms can help you make informed decisions. Browse our glossary for common definitions. :

Boiler

A boiler is a sealed container where water is heated under pressure used for central heating or domestic use. 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. . 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. . This system is ideal for larger homes

BTU (British Thermal Unit)

A BTU is a unit of heat . It's used to express the heating capacity of a boiler. A higher BTU rating indicates a more powerful boiler. . 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.. Look for a boiler with a high AFUE rating to minimize your energy consumption and lower your heating bills.

Expansion Tank

An expansion tank manages increased water volume due to temperature rise It prevents pressure buildup in the heating system and helps maintain safe operation. for sealed heating systems. .

Circulator Pump

A circulator pump circulates water 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 releases excess pressure from the boiler system, preventing damage or explosions. . It protects against overpressure situations.

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.

How can I make my boiler more energy-efficient?

Here are some tips to improve your boiler's efficiency: :
  • Upgrade to a high-efficiency condensing boiler: Condensing boilers are significantly more efficient than older non-condensing boilers.
  • Install a programmable thermostat: A programmable thermostat allows you to set different temperatures for different times of the day , helping to reduce energy waste and lower heating costs. .
  • Insulate your home: Good insulation helps trap heat, keeping your house warm and reducing the amount of work your boiler needs to do. .
  • Service your boiler annually: Regular servicing ensures your boiler is operating at optimal efficiency and safety.
  • Powerflush your system: Over time, sludge and debris can build up in your heating system, reducing efficiency. A powerflush cleans the system, improving circulation and heat output.
These measures will not only improve efficiency and reduce energy waste, they also improve the lifespan and reliability of your boiler system. .

What is a boiler's BTU rating?

A BTU (British Thermal Unit) measures the amount of heat energy a boiler can produce in an hour. It indicates the heating capacity of the boiler. A higher BTU rating means a greater heating capacity. Consult a professional for an accurate assessment. Incorrectly sizing your boiler will reduce efficiency and increase energy bills.

What is a boiler’s AFUE rating?

AFUE stands for Annual Fuel Utilization Efficiency. measures how efficiently a boiler converts fuel to heat over a year. It's expressed as a percentage. 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 higher the AFUE, the more efficient the boiler and the less fuel you'll need to heat your home, resulting in cost savings.. Look for a high AFUE rating when shopping for a new boiler.
