Technical Applicability Notes

Transparent guidance on where our heating systems perform well and where alternative solutions may be more appropriate.

Temperature & Pressure Boundaries

Our fire-tube steam boilers operate at design pressures up to 25 bar and saturated steam temperatures up to 224 degrees Celsius. Applications requiring superheated steam above 300 degrees Celsius or pressures exceeding 40 bar fall outside our standard product range and require specialist water-tube or once-through boiler designs from high-pressure manufacturers.

Fuel Supply Requirements

Gas condensing boilers require a stable natural gas supply at minimum 20 mbar inlet pressure. In regions with unreliable gas infrastructure, dual-fuel burners (gas/oil) provide continuity but add 15-25% to equipment cost. Biomass and hydrogen-ready boilers are available only in limited capacity ranges (200-1,000 kW) and carry longer lead times of 16-20 weeks.

Heat Pump Climate Constraints

Air-source heat pump efficiency (COP) drops from 4.5 at +7 degrees Celsius ambient to approximately 2.0 at -15 degrees Celsius. In continental climates with extended sub-zero winters, bivalent systems pairing a heat pump with a gas boiler backup are recommended. Ground-source heat pumps maintain stable COP year-round but require borehole drilling that adds 30-50% to installation costs.

Water Quality Dependencies

Condensing boiler heat exchangers require feed water hardness below 150 mg/L CaCO3 to prevent limescale fouling. Installations in hard-water regions must include water softening treatment, adding ongoing chemical and maintenance costs of approximately 800-1,500 EUR per year for a typical 500 kW plant.

Space & Access Requirements

Industrial steam boilers above 2,000 kg/h require dedicated plant rooms with minimum 2.5 m clear height, forklift access for tube replacement, and compliance with local pressure vessel inspection access codes. Compact wall-hung boilers suit confined spaces but are limited to 150 kW per unit.

Lead Times & Availability

Standard condensing boilers (24-150 kW) ship within 2-4 weeks from European stock. Custom-engineered steam boilers above 5,000 kg/h have lead times of 14-22 weeks depending on pressure class and material specifications. Emergency replacement stock is maintained at 20 service centres for the most common commercial models only.
