FAQs
What are the benefits of an instantaneous water heater?
Instant hot water
Hot water on demand is super convenient and makes washing and cleaning a breeze. You never have to worry about running out of hot water as it is heated there and then as you need it, across multiple appliances or fixtures, promising consistent performance.
Energy-saving
Instantaneous water heaters only heat water when needed, so less energy is wasted compared to storage water heaters which keep greater volumes of water heated for potential use. Their energy efficient heating process is cost effective and can help to lower energy bills.
Save space
Instant water heaters offer a compact design that can be easily wall-mounted under a bathroom or kitchen sink in smaller homes, offices or apartments where space is limited.
Improved water quality
Storage tank heaters are routinely subject to heat and can begin to rust over time. However, instantaneous water heaters provide hot water directly from the source, reducing the risk of contamination.
Easy to maintain
The initial cost to set up an instantaneous water heater can be higher than traditional storage tank installation but can provide long-term energy savings. They typically have a longer lifespan, reducing the need for frequent repair or replacement.
How much energy does an instant water heater use?
The energy use of instantaneous electric water heaters is relatively low compared to traditional storage tank water heaters. Factors such as water flow rate, temperature settings and the size of the unit can impact the amount of energy your water heater uses. Refer to the manufacturer's guidelines or a plumber if you would like more information on the energy efficiency of your electric water heater.
How do I choose the right size for my instantaneous water heater?
Planning for a new water heater involves considering all the hot water devices that may need to be used simultaneously, calculating the flow rate needed and determining the temperature you will need based on the temperature of the incoming water. Consulting the manufacturer's guidelines and a professional plumber will help to determine the right size water heater to comfortably meet your needs.
What type of energy sources can be used to power an instantaneous water heater?
Electric tankless heaters are the most popular type as they are easy to install and require minimal venting. However, natural gas can also be used, especially for larger or commercial properties, while other energy sources such as solar and LPG can also be used.
How do I know if my instantaneous water heater needs to be replaced?
There are several things to look out for that could suggest your water heater is not operating as efficiently as it once was and may need replacing.
Most tankless water heaters have a lifespan of around 20 years. Inconsistency in temperature or hot water not reaching the desired temperature is a sign that it's time to consider a replacement, as are unusual noises or signs of leaking.
