Instant water heaters are an efficient solution for delivering hot water on demand. For smaller, point-of-use applications like a single sink or shower, single-phase and open-vented models are ideal. They’re compact, energy-efficient, and easy to install, providing an endless supply of hot water right where you need it.
If you need hot water for multiple outlets, a three-phase electric instant water heater is a better option. These units are designed to handle higher demand, making them perfect for larger homes or businesses. With both types, you'll enjoy the convenience of continuous hot water without the need for bulky tanks, ventilation, or flues.

What’s the difference between single-phase and three-phase water heaters?
Single-phase water heaters work best for smaller, point-of-use applications like a sink or shower, while three-phase models can handle the higher demand needed for multiple outlets. If you're looking for an electric instant hot water heater for a single spot, go for a single-phase. But if you need to provide hot water for several points at once, a three-phase tankless instant water heater is the way to go.
How do these heaters save energy?
Both single-phase and three-phase instant hot water systems are great for saving energy. They only heat water when you need it, so you’re not wasting energy like with traditional storage tanks. It’s an efficient way to get hot water on demand without driving up your energy bills.
Can I use a single-phase water heater for multiple outlets?
Single-phase water heaters are designed for one outlet, like a sink or shower, and aren’t meant for handling multiple outlets at once. If you need hot water at multiple points, like in a larger home or business, a three-phase electric instant hot water heater will ensure you have a steady supply across all outlets.
Are these water heaters suitable for both residential and commercial use?
Yes, single-phase units are great for homes, especially smaller spaces where only one outlet needs hot water. On the other hand, three-phase instant hot water systems are perfect for larger homes or commercial properties where hot water is needed at several points simultaneously.
