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.

A fantastic and trustworthy plumber. Went out of his way to ensure the end result was that of a highly professional standard. Additionally, Stuart was able to explain how the shower likely broke and backed it up with visual evidence (ie opened up the shower parts and pointed out the faults). I couldn't fault the job he did.

Joshua Richard is very friendly and polite person. He has real patience to understand the issues correctly and rectify it. He came to replace the old led water pipe to PVC pipe. It was a bit tricky job and he had to dig the ground to connect the pipe and secured the connection. Joshua is a professional and skilful person and I would highly recommend him for any sort of plumbing tasks. I would definitely hire him for any of my future plumbing and gas related issues. Good luck mate.

We had great experience with Tony for another job so gave him a new job of installing 2 new taps and a new en-suite. He was very responsive until we paid the deposit and turned up to do the job 5 weeks after the initial scheduled date. We found tap leaks right after the job. He turned up twice to fix but unable to do so. We reached out again but he didn’t respond. Our opinion is that either the materials he ordered are of poor quality or he’s just can’t fix a tap leak.

The previous review was done under duress with Billy standing over me. The truth is, he disappears for considerable lengths of time (days), leaves equipment behind so you can't hire anyone else, switches his phone off so you can't contact him during this time and has the attitude of a bully. He removed our toilet to fix a blocked pipe but then left it so it wasn't fixed back to the floor properly and moved around, when we were in the process of selling our flat, with surveyors coming round. Not recommended.
