1. What is an Electric Water Heater?
An electric water heater is a device that uses electricity to heat water, providing a reliable and consistent supply of hot water for your home. Unlike gas-powered heaters, electric water heaters rely on electrical heating elements to raise the temperature of the water stored inside the tank. These systems are ideal for households without access to gas lines or those looking for an alternative to traditional gas heaters.
2. How Does an Electric Water Heater Work?
Electric water heaters function by using one or more heating elements inside the water tank. When you turn on the heater, electricity passes through these elements, generating heat. The heated water is then stored inside the tank until needed. In some models, a thermostat is used to control the water temperature, ensuring that it doesn’t get too hot or too cold.
Key Components of Electric Water Heaters:
- Heating Elements
- Thermostat
- Water Storage Tank
- Pressure Relief Valve
3. Types of Electric Water Heaters
There are several types of electric water heaters available, each suited for different needs:
- Storage Water Heaters
These are the most common type, featuring a large tank where hot water is stored until needed. They come in various sizes, depending on the household’s requirements. Popular models on Amazon UK:
Electric Storage Water Heater – 50 Litre
Electric Storage Water Heater – 80 Litre - Tankless (Instant) Water Heaters
These heaters don’t store water but heat it on demand. They’re more energy-efficient and save space. Popular models on Amazon UK:
Tankless Electric Water Heater – Compact
Instant Electric Water Heater – Energy Efficient - Heat Pump Water Heaters

4. Advantages of Using an Electric Water Heater
There are several reasons why electric water heaters are popular among homeowners:
- Energy Efficient: Electric heaters are efficient, especially tankless models that only heat water when needed.
- Lower Initial Costs: Compared to gas water heaters, electric models are generally more affordable.
- Easy Installation: Electric water heaters do not require gas lines, making the installation process simpler and cheaper.
- Safe: With no gas combustion, electric heaters are safer and have no risk of carbon monoxide leaks.

5. Disadvantages of Electric Water Heaters
While electric water heaters have many benefits, they also have some drawbacks:
- Higher Running Costs: Electricity is often more expensive than gas, making the operational costs higher, especially for larger households.
- Slow Heating: Storage models can take longer to heat large amounts of water compared to gas heaters.
- Power Outages: If there’s a power outage, you won’t have access to hot water.
6. How to Choose the Right Electric Water Heater for Your Home
When selecting the best electric water heaters, consider these factors:
- Size and Capacity: Choose a model that fits your household’s hot water needs. For example, a family of four may need a larger tank than a single person.
- Energy Efficiency: Look for models with high energy efficiency ratings to save on long-term operating costs.
- Installation Space: Ensure you have adequate space for the heater, especially if you’re opting for a storage model.
- Budget: Consider both the upfront cost and long-term energy costs when making your choice.
For an average household, a 50-80 liter storage water heater is typically sufficient. If you’re short on space or need hot water instantly, a tankless model may be the better option.
7. Energy Efficiency and Cost of Running an Electric Water Heaters
One of the primary concerns for homeowners is the cost of running an electric water heater. The good news is that modern electric water heaters are designed to be as energy-efficient as possible.
Key Tips for Reducing Energy Costs:

- Regularly insulate the water tank and pipes to minimize heat loss.
The average cost to run an electric water heaters depends on the size of the unit, your location, and your household’s water usage. However, many energy-efficient models can help reduce these costs over time.
8. Installation of Electric Water Heaters
Installing an electric water heater is relatively straightforward and can often be done without professional help. However, for more complex systems or if you’re not comfortable with electrical work, it’s recommended to hire a professional.
Key Steps in Installation:
- Turn off the power supply.
- Disconnect the old heater (if replacing).
- Install the new unit according to the manufacturer’s instructions.
- Connect the water and power supply.
