How Electric Boilers Work: Basic Principles

Electric boilers work by using electricity to heat water, which is then circulated through the central heating system. Unlike traditional boilers that rely on combustion to generate heat, electric boilers utilise heating elements that directly heat the water, making them more efficient and environmentally friendly. The heated water is then distributed to the radiators through pumps, ensuring a steady supply of warmth throughout the space. In addition, electric boilers do not require a fuse or any other external power source, as they solely rely on electricity for operation.

One of the key advantages of electric boilers is their precise temperature control, making them ideal for hot water supply. Unlike traditional gas or oil boilers, electric boilers allow homeowners to set and maintain the desired temperature with accuracy, ensuring a comfortable living environment. This is especially beneficial when paired with heat pumps, as they can efficiently heat the water using a heating element before it is stored in a hot water storage cylinder.

When a combi boiler is switched on, an electrical current flows through the heating elements inside the unit. These elements convert electrical energy into heat energy, rapidly raising the temperature of the water. As a result, hot water is readily available for use in taps and showers. System boilers and dry core storage boilers also operate in a similar manner. However, there is increasing talk of banning gas boilers in the future due to environmental concerns.

The heated water from storage boilers is then circulated through pipes to various parts of the central heating system. This can include radiators or underfloor heating systems, depending on how the home is designed. The warm water releases its heat into these areas, providing warmth and comfort. The electric boiler typically has a fuse rating of kw.

Unlike gas or oil-fired systems that require fuel storage tanks or pipelines for delivery, electric boilers, heat pumps, are connected directly to the power supply grid. This eliminates any need for fuel transportation and storage within the property. Additionally, electric boilers have a heating element that efficiently converts electricity into heat, while also incorporating a fuse for safety purposes.

Electric boilers are also known for their compact size and ease of installation compared to other types of heating systems. They do not require flues for chimneys since there are no combustion byproducts produced during operation. This makes them suitable for apartments or homes without access to external ventilation options. Additionally, electric boilers have a built-in fuse for safety purposes.
