 Immersion heater experts

What is an immersion heater?

An immersion heater is an electric heating element placed inside a hot water tank to heat water directly. It works independently of your central heating system, making it a versatile option for heating water. Immersion heaters can act as the primary source of hot water or serve as a backup to a boiler. They are particularly useful in homes without gas connections or as a supplementary water heating solution.

Advantages and disadvantages of an immersion heater

Advantages:

  • Independent Operation: Immersion heaters don’t rely on a central heating system, providing hot water even if your boiler fails.
  • Energy Source Flexibility: Suitable for homes without gas connections or for using renewable electricity sources.
  • Backup Heating: Many households use immersion heaters as a backup option for their main hot water system.

Disadvantages:

  • Higher Running Costs: Heating water with electricity is often more expensive than gas-powered systems.
  • Time-Consuming: Heating a full tank of water can take longer than instant water heaters.
  • Manual Operation: Unless connected to a timer, immersion heaters must be turned on and off manually to avoid wasting energy.

Immersion heater cost

The cost of installing or replacing an immersion heater depends on the type of heater and whether a new hot water tank is required:

  • Immersion Heater Replacement: Replacing an existing immersion heater typically costs between £150 and £300, including parts and labor.
  • Hot Water Tank Installation: Installing a new electric hot water tank with an immersion heater can cost £500 to £1,000, depending on the tank size and complexity of the installation.
  • Running Costs: Operating a hot water immersion heater costs around £0.20 to £0.35 per kilowatt-hour, depending on electricity rates. Using a timer to heat water during off-peak hours can help reduce costs.

Other immersion heater and hot water tank FAQs

Can I change an immersion heater myself?

While it’s possible for someone with plumbing knowledge, it’s recommended to hire a professional to ensure safe installation and compliance with regulations.

How long does it take to heat water with an immersion heater?

Heating a full tank typically takes 1 to 2 hours, depending on the tank size and the heater’s wattage.

Do immersion heaters work with solar panels?

Yes, immersion heaters can be connected to solar PV systems to use excess electricity for water heating, making them more energy-efficient.

I recently had Luke and his team widen an opening between two rooms in my property, which was a sizeable job requiring the installation of a steel beam. The work was managed efficiently, and great care was taken throughout the project. I’m very pleased with the results and would highly recommend Luke and his team for their professionalism and attention to detail.

Anthony was brilliant from start to finish from initial quote to coming to the job to finish. He ripped out all the poor work done by the original contractor and replaced it all with the correct materials and left the house in a clean which didn’t happen when we originally had the bathroom fitted. He come back the week after and repaired the ceiling in the living room which had been damaged by the leaking shower and now everything is done I’m so happy with all that has been done.

He ignored my text & left half the panel working buttons, unusable after he finished saying don’t use them, they do nothing any way. He quoted £85 but charged £102. I paid what he quotes me. In England, VAT is included in the quoted price unless explicitly stated otherwise. Every quote I’ve paid before included VAT or clearly mentioned it. This isn’t the U.S., where tax is added afterward. For the sake of £17, you’ve lost a customer looking to buy a new boiler.
