 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.

Mo did an amazing job unblocking my drains. The work involved changing all the pipe work including the outside pipes whilst there was torrential rain. He was professional and possessed expert knowledge about all sorts of household jobs. I found his prices were reasonable especially given that he worked solidly for five hours and resolved the problem that very same day.
