Replacing an immersion heater with an electric boiler can be a viable option for those looking to save space and potentially reduce energy costs. This comprehensive guide will delve into the technical specifications, installation and cost considerations, key factors to keep in mind, and DIY-friendly aspects of this home improvement project.
Technical Specifications
Instantaneous Water Heaters
Instantaneous water heaters, such as the Strom SEIH11KTS1, offer a compact and efficient solution by providing instant hot water without the need for a bulky copper tank. These heaters are available in a range of power ratings, including 11kW models, making them suitable for various household needs.
Electric Boiler Options
For a 2-bedroom electric-only flat, smaller tank options like 25-liter instant point-of-use systems from brands like ZIP, Ariston, and Heatrae Sadia can be a suitable choice. These systems are classified as instant point-of-use if they have a volume smaller than 55 liters, ensuring a compact and space-saving installation.
Smart Cylinders
Mixergy’s smart cylinders, which come with unvented cylinders and smart controls, can be a valuable option. These systems are designed to be powered by solar PV, helping to reduce energy costs and promote sustainable hot water solutions.
Installation and Cost
Installation Time
Replacing an immersion heater with an electric boiler typically takes between two hours and half a day, depending on the complexity of the installation. Factors such as the existing plumbing setup, electrical requirements, and the specific model being installed can influence the overall installation time.
Cost Savings
Instantaneous water heaters can help reduce energy costs by only heating water as needed, rather than maintaining a large tank of hot water. This on-demand heating approach can lead to significant savings on energy bills, making it a more efficient alternative to traditional immersion heaters.
Key Considerations
Bath Filling
Instantaneous water heaters can fill a bath, but their performance may vary depending on the specific model and the temperature of the incoming water. While they can handle bath-filling tasks, they might not be as efficient as gas combi boilers in this regard, as the latter can provide a more consistent and powerful flow of hot water.
Electric Shower Compatibility
Electric boilers can work seamlessly with electric showers, which are a common feature in all-electric flats. This compatibility ensures a smooth integration of the hot water system and the shower, providing a convenient and reliable hot water solution.
DIY Considerations
Space Savings
Electric boilers can free up valuable space by eliminating the need for a copper tank, making them an ideal choice for smaller flats or apartments where space is at a premium.
Energy Efficiency
Carefully selecting the right electric boiler or instantaneous water heater can help reduce energy costs and minimize waste, contributing to a more energy-efficient home.
Conclusion
Replacing an immersion heater with an electric boiler can be a practical and cost-effective solution for homeowners looking to optimize their hot water system. By understanding the technical specifications, installation considerations, and key factors to keep in mind, you can make an informed decision and enjoy the benefits of a modern, efficient, and space-saving hot water system.
