What Size Instantaneous Electric Hot Water Heater Do I Need For My Home?

Are you thinking of installing an instantaneous electric hot water heater in your home? If so, you’ve come to the right place. Instantaneous electric hot water heaters are a great way to save money on energy bills and ensure a steady flow of hot water. But with so many sizes to choose from, it can be tricky to decide what size is best for your home.

The size of the instantaneous electric hot water heater you need depends on a few factors, including the number of people in your household and how much hot water you use each day. It’s important to get the right sized heater for your needs as too small a heater will struggle to meet demand, resulting in lukewarm showers and running out of hot water. On the other hand, getting one that’s too large will mean you’re paying for more energy than you need and could cost more upfront.

To work out the size of instantaneous electric hot water heater you need for your home, start by calculating how much hot water your household uses each day. A family of four typically needs around 400 litres (or 16kWh) per day – but this can vary depending on how often you shower, run appliances like washing machines or dishwashers, or if someone runs a business that requires a lot of hot water (like a hair dressing salon).

Once you have an idea of how much hot water you need each day, it’s time to look at what size instantaneous electric hot water heater is suitable for your needs. Generally speaking, sizes range from 10-25 litres/minute flow rate (or 2-5kW power output). So if we use our example family of four who need 400 litres per day, they would require an instantaneous electric hot water heater with at least 16 litres/minute flow rate (or 3kW power output).

It’s also worth considering any additional features that may be available when choosing which type and size is right for your home. Some models come with digital temperature control displays so that you can easily adjust the temperature settings to suit different households’ needs or preferences – these are great if there are young children or elderly people living in the house who need lower temperatures. Other features like temperature pre-sets or timers can also help save energy costs by only heating when needed.

So there you have it – just follow these steps and you’ll be able to work out what size instantaneous electric hot water heater is right for your home! If in doubt though, always consult an experienced professional who can help advise on the best model for your individual needs and budget.
