Williamson’s FreeStyle 155 k Btuh (FS-155) input is a wall mount gas-fired condensing boiler and is available in combi and heat models. The FS-155 combi unit provides 4 gpm of domestic hot water. The FS-155 joins Williamson’s current 80 and 120 k Btuh input units. The models are designed with a single-tube large diameter stainless steel heat exchange. A digital display control and 24 Vac thermostat relay are standard with each unit. The FreeStyle provides modulating combustion with a 10 to 1 turndown ratio allowing system design flexibility.
