How to choose hot-water boiler house capacity

Correctly sized boiler house capacity is a balance between reliability and cost. Too small and it won’t cover peak loads; too large and you overpay on capital costs and lose efficiency at partial load.

What determines capacity

• Site heat load — heating, hot water supply, process needs.
• Temperature curve — winter (110/60 °C) and summer (80/40 °C) modes.
• Redundancy — whether a backup boiler is needed for maintenance.

A modular approach

Ready boiler houses are built from standardised modules: for example, 8 MW is two FG-W4000 boilers, and 16 MW is four. This simplifies maintenance and redundancy — one boiler can be taken out for service without stopping the whole plant.
