What a Main Boiler Service Includes

A typical service for a Main boiler should be carried out by a Gas Safe registered engineer and includes the following steps:

  1. Visual Inspection: The engineer will check the boiler for any visible signs of damage, wear, or corrosion. They will also ensure that the installation meets current safety regulations.

Main Boilers Technical

Main boilers are designed to offer reliable and efficient performance while being user-friendly and affordable. Their technical features reflect their focus on providing practical, no-nonsense heating solutions for a wide range of homes.

1. Energy Efficiency

All Main boilers use condensing technology to increase energy efficiency by capturing heat from exhaust gases that would otherwise be lost. This results in higher efficiency and lower carbon emissions.

Main boilers are rated A for efficiency, with typical efficiencies around 89% to 93%. This means they convert nearly all the fuel into heat, minimizing waste and lowering energy bills.

2. Power Output

Main boilers are available in various power outputs, typically ranging from 15kW to 30kW, depending on the model and type.

  • 15kW to 18kW: Suitable for smaller homes or apartments with one bathroom.
  • 24kW to 30kW: Suitable for medium to larger homes with more than one bathroom.

Main boilers often feature a modulation ratio, meaning they can adjust their output to match the heating demand. This enhances efficiency and reduces wear on the boiler.

3. Heat Exchanger

Main boilers typically use aluminium heat exchangers in their compact models. Aluminium offers good heat transfer and is lightweight, contributing to the compact design. Some models might use stainless steel, known for its durability and resistance to corrosion.

The design of the heat exchanger in Main boilers helps to ensure low NOx emissions, making them more environmentally friendly and compliant with stringent emissions regulations.

4. Controls and Interface

Main boilers are designed with a straightforward control panel that is easy to use, featuring basic dials and buttons for temperature control and system settings.

Main boilers can often be paired with smart thermostats, allowing for remote control and scheduling via smartphone apps. This can further enhance energy efficiency by optimizing heating schedules.

5. Flow Rate

Combi boilers from Main typically offer flow rates between 10 to 12 liters per minute for the 24kW to 30kW models. This is adequate for homes with one or two bathrooms but may be limited if multiple outlets are used simultaneously.

6. Safety Features

  • Flame Supervision Device (FSD): This device shuts off the gas supply if the flame is extinguished, ensuring safe operation.
  • Overheat Thermostat: Protects the boiler from overheating by shutting it down if temperatures exceed safe limits.
  • Pressure Relief Valve: Automatically releases pressure if it becomes too high, preventing potential damage to the boiler or heating system.

7. Gas Type

Most Main boilers are designed for natural gas, which is the most common type of fuel in the UK. Some models can be converted to run on LPG (liquefied petroleum gas) with a conversion kit, providing flexibility for homes that are off the main gas grid.

8. Noise Levels

Main boilers are designed to operate quietly, with noise levels often below 50 decibels (dB). This makes them suitable for installation in or near living areas.

Main Boiler Age

How Long Do Main Boilers Last?

Main boilers, like most modern boilers, typically have a lifespan of around 10 to 15 years when properly maintained.

When to Consider Replacement

  • Frequent Breakdowns: If the boiler starts breaking down frequently, it might be more cost-effective to replace it rather than continue paying for repairs.
  • Reduced Efficiency: As boilers age, they may become less efficient, leading to higher energy bills. If the boiler’s efficiency has dropped significantly, replacing it with a newer, more efficient model might be a good investment.
  • Outdated Technology: Older boilers may lack modern features like smart controls or condensing technology, which can save energy and improve convenience.
