Conventional Traditional Boilers

A conventional traditional boiler, also known as a regular, heat-only, or open vent boiler, is a type of boiler system commonly used in older homes and larger properties. Here are the key features, benefits, and how it works:

Key Features of Conventional Traditional Boilers:

Separate Components: It consists of several separate components, including the boiler itself, a hot water storage cylinder, a cold water storage tank (usually in the loft), and a feed and expansion tank.

Stored Hot Water: Unlike combi boilers, conventional boilers heat water that is then stored in a hot water cylinder, providing a reservoir of hot water.

Suitable for Larger Homes: Can meet high hot water demand and serve multiple bathrooms simultaneously without significantly reducing water pressure.

What is a Conventional Traditional Boiler?

Benefits of Conventional Traditional Boilers

Multiple Hot Water Outlets: Can supply hot water to multiple taps and showers at the same time without a significant drop in water pressure.

Backup Options: Often includes an immersion heater in the hot water cylinder, which can provide hot water if the boiler fails.

Compatibility with Older Systems: Ideal for properties with an existing traditional heating system, as it can often be connected to existing pipework and radiators with minimal modification.

High Flow Rates: Generally provides higher flow rates of hot water compared to combi boilers, especially important in homes with multiple bathrooms.

How Conventional Traditional Boilers Work

Heating: The boiler burns fuel (typically gas, oil, or electricity) to heat water. This heated water is then circulated through radiators or underfloor heating to warm the home.

Hot Water Storage: The boiler also heats water that is stored in a hot water cylinder. The cold water from the mains is stored in a cold water tank, and it is fed into the hot water cylinder where it is heated by the boiler.

Expansion Tank: The feed and expansion tank accommodates the expansion of water when it is heated and maintains the water level in the system.

Ideal Applications for Conventional Traditional Boilers: 

Large Homes: Suitable for larger properties with high hot water demand and multiple bathrooms.

Multiple Hot Water Outlets: Ideal for homes where multiple hot water outlets (taps, showers, etc.) are used simultaneously.

Existing Traditional Systems: Perfect for homes with existing traditional heating systems, reducing the need for extensive plumbing changes.
