Can I retain gas for hot water replacement in existing commercial buildings?

Yes. While new builds face restrictions on new gas connections, existing commercial buildings may continue to use gas. Modern condensing gas water heaters improve efficiency and reduce flue losses compared to legacy units.

What site constraints should be assessed before replacing a commercial water heater?

Confirm access and handling (doorways, steps, weight), existing isolation valves and pipework modifications, drainage for condensate and maintenance, and the condition and suitability of the flue system.

Do water quality and building location affect system selection?

Yes. Hard water areas benefit from indirect heating to limit limescale, while soft water regions may require more corrosion-resistant construction such as stainless steel or enhanced porcelain.

Should the flue be replaced during a hot water system upgrade?

Often yes. Aluminium flues have a typical lifespan of ~15 years; older negative-draught, non-condensing flues are not suitable for modern condensing appliances and should be renewed to meet regulations.

What features improve long-term performance and compliance?

Look for onboard energy and water metering, remote connectivity (e.g. app or BMS integration) for monitoring and fault alerts, and support for future energy blends such as 20% hydrogen in compatible gas appliances.
