Discover the benefits of immersion heaters

Immersion heaters ensure a consistent supply of hot water and offer better energy efficiency compared to other heating methods and immersion heater alternatives, making them a popular choice for heating systems. They are easy to install and maintain, and their built-in thermostat allows for accurate control of the liquid's temperature, ensuring optimal performance and preventing overheating.


How do immersion heaters work?

An electric immersion heater works in a similar way to a kettle, but on a much larger scale. It uses a large hot water cylinder and can be switched on and off at the mains to save energy when needed. An electric resistance heater (a metal loop or coil) heats the surrounding water and is controlled by a thermostat to ensure it reaches the desired temperature.

What are the benefits of using an immersion heater?

Immersion heaters are energy efficient as they heat the liquid they are immersed in directly, resulting in minimal heat loss and lower energy consumption. An immersion heater is also mains powered but can also be connected to more renewable energy sources such as solar panels. They're also highly durable and reliable, typically made up of high-quality materials such as incoloy and copper which are resistant to wear and tear and require little maintenance. They can also be used as a back-up option water heater for a combi boiler as they are separate from your central heating boiler or radiators.

How do I choose the right immersion heater?

Here are three key points to consider before choosing your immersion heater:

Temperature control: Depending on your application, you may need accurate temperature control. Look for immersion heaters with built-in thermostats or temperature sensors for precise temperature regulation.

Safety features: Opt for immersion heaters with safety features such as overheat protection and automatic shut-off systems to ensure safe operation.

Installation and mounting: Consider the installation space and mounting options available in your setup. Immersion heaters come in various mounting styles, such as flanged, screw plug, or over-the-side heaters. Immersion heaters are usually straightforward to install and can be mounted in tanks, containers, or other vessels.
