Continuous flow hot water heaters are exclusively gas powered and as their name implies, they generate instant hot water, as and when it is needed – with super efficiency.

Continuous flow heaters are ideal for delivering hot water to kitchens, en-suite facilities in hotels and wash rooms. They are particularly useful for shower blocks where consumption can be volatile or where high volumes of continuous hot water is needed such as in production plants and food processing.

Benefits of an instant hot water boiler

Super-efficient continuous flow

Continuous flow hot water heaters can typically deliver thousands of litres of hot water per hour via a compact burner and heat exchanger module that is designed to condense moisture from the flue gases.

Easy integration with renewable systems

Some systems can also be intelligently linked into solar thermal systems to further boost efficiency and reduce fuel consumption.

Continuous flow hot water heaters can be stand-alone or daisy-chained to form one, large, virtual heater that can scale output up or down to suit a broad range of flow and temperature demands.

Low-cost, trouble-free installation

These types of heaters are compact and relatively inexpensive so can be installed in a broad range of locations.

They can be hung on interior or exterior walls or on racks. External models require no flue work as the flue is built in. Internal models, when hung on a boundary wall need only a short, inexpensive, horizontal, balanced flue that is the width of the wall.

Hot water on demand

Many businesses will be heating water in an insulated storage tank using oil-fired condensing boilers. This is fine if the daily consumption is highly predictable in terms of volume and time of use.

However, where consumption is unpredictable a continuous flow heater is the perfect high-efficiency, low-carbon solution.
