Continuous Flow Hot Water Systems & Heaters

What is a Continuous Gas Hot Water System?

Instantaneous gas hot water is a modern and efficient system that provides hot water on demand, exactly when you need it! Unlike traditional storage water heaters that keep a tank full of hot water at all times, the instantaneous gas hot water system heats the water as it flows through the unit, ensuring a constant and endless supply of hot water. Say goodbye to cold showers and hello to instant comfort with this innovative technology!

Is the continuous hot water system good?

Absolutely! The instantaneous hot water system is a fantastic choice for many reasons. Firstly, it offers endless hot water, so you’ll never run out, no matter how many people need a shower in your home. Secondly, it’s highly energy efficient, only heating water when required, which can lead to significant cost savings on your utility bills. Thirdly, it saves valuable space since there’s no need for a bulky storage tank. With all these benefits, it’s hard not to love the convenience and reliability of an instantaneous hot water system!

How does continuous gas hot water work?

The magic behind an instantaneous gas hot water system lies in its clever design. When you turn on a hot water tap, cold water from the mains starts flowing through the unit’s heat exchanger. A gas burner, ignited by a spark or a pilot light, heats the water rapidly as it passes through. Within seconds, you get a steady stream of piping-hot water at the perfect temperature! It’s a simple yet effective process that ensures you have hot water whenever and wherever you need it.
