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.

Ryan could not have been more helpful and friendly, it was a pleasure hiring him. He completed a complex job removing a broken boiler, installing a new one, re-routing a gas through 30m of new pipe and installing a radiator, then getting it all to work with our existing smart home system. We now have a lovely warm home and great hot water pressure. Thanks!

In relation to what Daniel can do, this was a small job, but we were very grateful that he was happy to take it on and help us out. He was really receptive to text messages, was very accommodating when we had to change the original work date, and was keen to get back to us as soon as the counters were re-fitted, so we had a working kitchen again. Really lovely chap, and we'd happily have him back for any other work we may need. Highly recommend him.

*Professional Summary:* After obtaining a degree and purchasing my first home, I quickly realised that I had a knack for DIY and home improvement. This passion led me to retrain in various trades, where I honed my skills and developed a deep understanding of the construction industry. Leveraging my hands-on experience, I transitioned into project management, where I now hold significant qualifications. Today, I use my expertise to bridge gaps in projects as I work towards securing larger industrial contracts. My journey from DIY enthusiast to skilled PM has equipped me with a unique blend of technical and managerial skills, allowing me to excel in both the planning and execution of complex projects. *Business Philosophy:* At our company, we believe in valuing the skills and dedication of our tradesmen. Each team member not only earns a competitive wage but also benefits from a share of the company's profits at the end of the calendar year. This approach ensures that our workforce is motivated to deliver exceptional quality on every project. We don't work cheap; instead, we focus on delivering precisely what we promise, ensuring that our clients receive top-tier results and our tradesmen are rewarded for their hard work and craftsmanship. *Commitment to Quality and Safety:* We take our responsibilities seriously. Our company is fully insured, and our team is highly competent, holding a Safety Schemes in Procurement (SSIP) certification. We are committed to upholding the highest standards of safety and professionalism in every project we undertake. This commitment reflects our dedication to delivering not just quality work, but also a secure and compliant working environment for all involved. Our company operates on the principle that in any project, you can have it good, fast, and cheap—but only two at a time. This philosophy guides our approach to delivering quality work while managing client expectations. If you want something done quickly and to a high standard, it won’t be cheap because quality and speed require skilled labor and premium materials. Alternatively, if you need something done quickly and on a budget, you might have to compromise on the level of quality. Lastly, if quality and cost are your priorities, the project will take time, as we won’t cut corners to rush the job. This principle ensures that we remain transparent with our clients. NOW LETS GET TO WORK!
