Frequently Asked Questions About Water Heaters
Does an instant water heater use a lot of electricity?
Instant water heaters have high wattage but only consume electricity when in use. This means they can be more energy-efficient than storage water heaters, especially for smaller households with intermittent usage.
What capacity water heater do I need for my home?
The ideal capacity for an electric water heater depends on your household size and hot water needs. A general guideline is 25-35 liters per person, but other factors such as the flow rate of your shower head or whether you use a bathtub can affect the amount of water you need.
Is it safe to leave a water heater on all the time?
Yes, it is generally safe to leave a water heater on. Modern water heaters have thermostats that maintain the desired temperature and safety features to prevent overheating.
Do I need a pump for my water heater?
A pump is usually not necessary unless you have low water pressure or want to boost the flow rate for showers and other bathroom fittings. Consult a plumber to assess your water pressure and needs.
