About Conventional Boilers

The most common form of boiler found in UK houses is the conventional boiler, usually referred to as regular or heat only boilers.

 

They operate by heating water that is kept in a hot water cylinder. These boilers are originally designed to work on gravity with an external circulating pump. They are also connected to a cold water storage tank and a feed and expansion tank typically installed in lofts.

 

Conventional boilers, in contrast to combi boilers, require much more space to house all the necessary tanks and external components.

 

For those considering upgrading to a conventional boiler, it’s essential to understand its requirements and benefits. Explore our pages on Conventional Boiler Prices and Full Central Heating Installations for more insights.

Hisory of Conventional Boilers

Conventional boilers have a long history dating back to the early 20th century. This is when they were first manufactured and started to appear in UK homes.

 

Initially, they were created to cater to larger properties like country homes and mansions to provide heating and hot water. These boilers were typically fueled by oil or coal.

 

However, with technological advancements over time, conventional boilers now come in modern gas and oil-fired models. As a result, they are now a popular choice for both domestic and commercial properties across the UK due to their efficiency.

Efficiency of Conventional Boilers

The efficiency rating of conventional boilers is generally between 70-80%, implying that nearly 30% of the fuel utilised is lost due to heat dissipation.

 

This is primarily due to the stored hot water cylinder, which can lose heat if not insulated appropriately. Nevertheless, modern conventional boiler models now feature advanced insulation, leading to reduced heat loss and increased efficiency. Consequently, this results in lower energy bills and reduced carbon emissions.

Pros of Condensing Boilers

  • Simultaneous Hot Water Supply – Can provide hot water to multiple taps and showers simultaneously without loosing pressure or noticing a change in temperature.
  • Compatibility with Various Heating Systems –  Conventional boilers are compatible with various heating systems, including underfloor heating or radiators, and unvented cylinders. Conventional boilers can be used with natural gas or oil which makes them a versatile option.
  • Renewable Energy Options – Conventional boilers can work with solar thermal panels that use sunlight to heat water. This integration can help reduce costs and lower carbon emissions. 

Cons of Condensing Boilers

  • Require More Space – Conventional boiler set ups can take up more space due to the need for a separate hot water cylinder, cold water tank and a feed and expansion tank.
  • Lower Efficiency – May not be as energy-efficient as other types of boilers such as combi boilers. This is due to heat loss and the need to heat a hot water storage cylinder.
  • More Expensive – Conventional systems are more complex and costly to install than combi or system boilers. The boilers themselves are more expensive and require external components such as circulating pumps. The process of installing a conventional boiler is difficult due to air locks. This can be adverted if the system is converted to a pressurised system whilst still using a conventional boiler.

Summary of Conventional Boilers

Conventional boilers remain a popular choice for homeowners due to their compatibility with various heating systems and reliability.

 

Conventional boilers may not be as energy-efficient as other types of boilers or Air Source Heat Pumps, but the fact that they can simultaneously provide hot water to multiple taps and showers may be more suited to requirements. This also makes them a better option than a combi boiler for larger homes and properties with multiple occupants.

 

When choosing a conventional boiler, consider factors such as your home’s size, hot water demand, energy efficiency rating, and installation and maintenance costs.

FAQ'S

A conventional boiler, also known as a regular or traditional boiler, is a type of central heating system that incorporates a boiler, hot water cylinder, and cold water storage tank. It provides heating and hot water to a property using a system of radiators and taps.

Conventional boilers heat water in the boiler, which is then circulated through radiators to provide heating. Additionally, they heat water stored in a hot water cylinder, which supplies hot water to taps and showers. Cold water from the mains is stored in a separate tank and fed into the boiler to replenish the hot water cylinder.

It’s recommended to service a conventional boiler annually to ensure it operates efficiently and safely. Regular servicing helps prevent breakdowns, prolongs the lifespan of the boiler, and maintains its warranty validity.

Yes, it’s possible to replace a conventional boiler with a more modern system such as a combi boiler or a system boiler. However, this may require modifications to your existing heating system and hot water setup. Consulting with a qualified heating engineer is recommended to determine the best option for your property.
