Hot Water boiler

Industrial hot water boiler with firing state, thermal lag, pressure response, and fault health.

What it is

An industrial hot-water boiler with modulating firing rate, thermal lag between firing and supply temperature, system-pressure response, and combustion indicators. Pairs with a circulation pump and a heating loop to model a full heating plant.

Used in

commercial-building — central heating plant, hot-water loop to AHUs

What it tracks

Member	Why it matters
`running`	Boiler operating state.
`firing_rate`	Modulating output as fraction of rated capacity.
`supply_temperature`	Delivered water temperature — lagged response to firing.
`return_temperature`	Loop-return water temperature, coupled to circulation pump.
`system_pressure`	Expansion behaviour with temperature.
`flue_gas_temperature`	Combustion efficiency indicator.
`fuel_flow`	Live burn rate.
`fuel_consumed_total`	Cumulative fuel used.
`co_emission`	Combustion health surface.
`circulation_pump_running`	Pump interlock — no circulation, no heating.
`runtime_hours`	Lifetime counter.

Fault modes

scale_buildup — reduced heat transfer, rising flue-gas temperature, efficiency loss.
flame_instability — CO emission spikes, firing-rate modulation issues.
circulation_pump_failure — no return-water flow, supply temperature runaway.

Key parameters

Parameter	Default	Unit
`rated_output_kw`	500	kW
`rated_pressure_bar`	6	bar
`supply_temp_setpoint_c`	80	°C
`return_temp_design_c`	60	°C
`efficiency`	0.88	—

Use cases

Central heating plant modelling with realistic thermal inertia.
Coupling with a circulation pump for cascade fault scenarios.
Combustion efficiency trending and scale-buildup detection.
Building heating-system analytics.
