Fast, On-Demand Heating with Instantaneous Systems

Instantaneous hot water systems heat water on the pass using high-output burners or heating coils, meaning you only pay for energy when the water is running. Because these units rely on precise electronic sensors and flow valves, keeping them in top working order requires professional expertise. We provide complete maintenance, repairs, and conversions, ensuring your continuous-flow system delivers accurate temperature control and instant hot water every time.

FAQ

Instantaneous Hot Water FAQs

Can an instantaneous system handle multiple showers at once?

Yes, as long as the unit is sized correctly for your household. Continuous flow units are rated by flow rate (litres per minute). We measure your household fixtures and fit a system that easily supports simultaneous showers and taps without a drop in pressure.

Why is my instantaneous hot water system shutting off mid-shower?

Mid-shower shutoffs are often caused by restricted water flow from a clogged filter screen, mineral buildup in the heat exchanger, or a faulty gas flow valve. A quick professional service usually clears this issue right up.

Are instantaneous hot water systems suitable for large families?

They can be when correctly sized for the household’s peak demand. An undersized unit may struggle when several showers or taps operate simultaneously.

How does an instantaneous hot water system work?

It heats water as it passes through the unit instead of storing it in a cylinder. Correct sizing is important so the system can meet the property’s simultaneous hot water demand.

Can you replace a storage tank with an instantaneous unit?

Often, but the available gas or electrical capacity, water pressure and pipe sizing must be assessed. The existing installation may require upgrades.
