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.

They contacted me really quickly which was fantastic in my urgent plumbing issue. However, the second contract that came round was a little disappointed with. Whilst the primary issue was fixed there was a new second issue that came about. He came a second time to sort but then wanted to further charge an emergency fee. I appreciate it was a weekend but something didn’t sit right. I called a completely different plumber who I trusted before and he said that the wrong part was used which meant it wasnt safe.

I hired this Mark to swap out seven radiators. Initially he quoted and I went ahead with the job. On the day before we arranged, he wanted to postpone because another job had run over, which caused some complications for me, but we managed to agree a new time. Unfortunately, he never showed up at the agreed time. I tried calling and messaging him several times but he ignored all attempts to get in touch. Very poor communication and reliability, and overall not a good experience at all.

My initial post on rated people was for a handyman to repair a wooden gate. Ben responded very quickly to the posting and on his review of the gate we agreed that repair was not feasible and the solution was to install a new gate. Ben worked hard to build and install a replica of the old gate and I am happy with the end result. I can recommend his craftsmanship in carpentry and attention to detail to ensure customer satisfaction.

Jon gave the best price compared to many other tradespeople. His work was also of sufficient quality although we had some major leaks due to bad seals. He came outside of work hours and fixed the issue for us. Removing one star because he cracked and broke some tiles and he couldn't fit the replacement tiles.
