Key Takeaways
- Different power ratings of electric showers deliver different flow rates of heated water.
- It is essential to consider the power outage possibility when selecting the wattage.
- Lower kW ratings provide a lower flow rate of water, while higher kW ratings offer a greater rate of water flow.
- Adequate water pressure and flow rates, as well as proper electrical infrastructure, are crucial factors to consider when upgrading electric showers.
Understanding the kW ratings of showers
To understand the kW ratings of electric showers, it’s important to know the different power options available.
Common kW ratings for electric showers in the UK range from 7.5kW to 10.5kW, with lower ratings providing a lower flow rate and higher ratings offering a greater rate of water flow.
The power rating of the shower determines the amount of water that can be heated and delivered, so it’s crucial to choose the appropriate kW rating for your needs.
What Are The Different kW Ratings Of Electric Showers
There are four common kW ratings for electric showers in the UK:
- 7.5kW
- 8.5kW
- 9.5kW
- 10.5 or 10.8kW
These kW ratings determine the flow rate of heated water that the electric shower can deliver.
Lower kW ratings, like 7.5kW and 8.5kW, provide a lower flow rate, while higher kW ratings, such as 9.5kW and 10.5kW, offer a greater rate of water flow.
It’s important to understand these ratings when buying a new electric shower, as choosing the wrong wattage can result in dissatisfaction and insufficient water flow.
When upgrading your electric shower, consider factors such as water pressure, the circuit breaker or fuse capacity, and the size of the electric cable. These considerations will ensure a successful upgrade to a more powerful electric shower.
Things To Consider When Upgrading Your Electric Shower
When upgrading your electric shower, there are several important considerations to keep in mind.
Firstly, you need to assess the water pressure and flow rates to ensure optimal performance.
Secondly, you must determine the appropriate fuse required for your chosen power rating and ensure that the electrical wire size is suitable, in most cases the you will need to replace your shower with one of the same rating.
Water Pressure And Electric Showers
Consider the minimum running pressure of 0.7 bar in your mains water supply when upgrading your electric shower. Proper water pressure is crucial for optimal performance and the flow of water.
Here are some key things to consider regarding water pressure and electric showers:
- Check the specific requirements of each electric shower system before purchasing.
- Ensure that the mains water supply meets the minimum running pressure of 0.7 bar.
- Adequate pipework diameter of at least 15mm is necessary for effective operation.
- Water pressure significantly impacts the performance of electric showers.
- Optimal functioning of electric showers depends on adequate water pressure.
When upgrading your electric shower, it’s important to keep these considerations in mind to ensure a successful upgrade. Adequate water pressure will ensure that your electric shower performs at its best, providing you with a satisfying shower experience.
Which Fuse Will Be Required
To ensure a successful upgrade of your electric shower, it’s important to know the appropriate fuse required for your specific power rating.
The power rating of your shower, measured in kW, determines the amperage required for the fuse. Different power ratings have different amperage requirements.
Use the table below as a guide:
| kW | Fuse Size (mcb) |
| 7.5 | 32 |
| 8.5 | 40 |
| 9.5 | 45 |
| 10.5 (or 10.8) | 50 |
For example, a 7.5kW shower typically requires a 32-amp fuse, while a 10.5kW shower may require a 45-amp fuse.
It’s crucial to consult with a qualified electrician to determine the correct fuse size for your specific shower. The electrician will also assess the compatibility of your existing electrical infrastructure and recommend any necessary upgrades.
Choosing the right fuse ensures safe and efficient operation of your electric shower, providing you with a refreshing and satisfying shower experience.
What size of cable do you need
To ensure a successful upgrade of your electric shower, it’s important to determine the appropriate size of cable needed based on the power rating of your shower. Choosing the right cable size is crucial for safe and efficient operation.
Use the table below as a guide but bear in mind that the length of the cable is also a factor in the size and you should always consult a professional:
| kW | Cable size |
| 7.5 | 6mm |
| 8.5 | 6mm |
| 9.5 | 10mm |
| 10.5 (or 10.8) | 10mm |
Frequently asked questions
Is a 9.5 kW shower powerful
Yes but a 10.5 or 10.8kW shower is the most powerful electric shower and no electric shower provides the flow rate that a mixer shower on a high pressure system would.
Will a higher kW shower be more powerful
If you’re wondering whether a higher kW shower will be more powerful, the answer is yes. A higher kW rating means a more powerful shower system.
The power rating of an electric shower determines the rate at which water can be heated and delivered. Higher kW ratings, such as 9.5kW and 10.5kW, offer a greater flow rate of water, resulting in a more powerful shower experience.
When choosing the best kW rating for your electric shower, consider your desired water flow and pressure requirements. It’s important to ensure that your water pressure meets the minimum requirements and that your electrical system can handle the higher power demands.
How many litres per minute is a 8.5 kW shower?
This will depend on the temperature of the water coming out of the shower, and this will vary on the temperature of the incoming water supply as well. But most 8.5kW showers can provide a maximum of 6 litres a minute.
Conclusion
In conclusion, understanding the best wattage (kW) for an electric shower is essential for optimal performance and satisfaction.
By considering factors such as water pressure, kW ratings, and fuse and electrical wire requirements, you can ensure a successful upgrade.
Take the time to evaluate your needs and select the appropriate wattage for your electric shower, and enjoy a refreshing and efficient shower experience and if you are looking for the best electric showers you can buy today click here.
