  • Do Electric Boilers Need Servicing?

Updated: June 25, 2024

Electric boilers, like any other type of boiler, require regular servicing. Proper maintenance and care can significantly extend the lifespan of your electric boiler. Electric boilers are an excellent choice for heating as they offer various advantages. They operate silently, occupy minimal space, have a lower carbon footprint, and are highly efficient in providing heat.

What is an electric boiler?

An electric boiler is a heating device that uses electricity to generate hot water or steam for heating purposes. Unlike traditional gas or oil boilers, which burn fossil fuels to produce heat, electric boilers utilize electricity as their primary energy source. They typically consist of heating elements submerged in water, which are

activated when electricity flows through them, heating the water to the desired temperature. Electric boilers are often used in homes and buildings where gas or oil heating systems are not feasible or preferred, and they are valued for their cleanliness, simplicity, and ease of installation.

Do electric boilers require as much maintenance as gas or oil boilers?

Well, not really. Electric boilers require less servicing and maintenance than gas or oil boilers. 

Why do electric boilers require less servicing?

Electric boilers have minimal maintenance requirements due to their fewer moving parts compared to other heating systems. However, it’s important to note that electric boilers are still complex appliances that operate

under pressure and involve heating elements and water. Neglecting proper care and servicing of your electric boiler can potentially result in costly issues with your heating system in the future.

An electric boiler is an appliance that is powered by electricity in order to boil water. Three different technologies are used for electric boilers. These are:

  • classic (using an element)
  • induction 
  • ionic (using a heat pump)

What advantages does a heat pump offer?

  • Installation is cheap
  • Can reduce bills and running costs
  • No moving parts and components
  • Quite efficient (99% efficiency rate)
  • There is no risk of carbon monoxide leakage
  • Can be paired with a solar system

What are the drawbacks of electric boilers?

  • Running costs are more expensive 
  • Require high voltage 
  • Can’t work without power 
  • They can struggle when heating a large home
