Built for reliable central heating and traditional hot water systems, the Firebird 20-26kW Elco Silverpac Oil Boiler is a robust “heat-only” solution ideal for homes with radiators and separate hot water cylinders. Specifically designed to perform as part of a sealed or open vent heating system, this external boiler delivers durable, low-maintenance performance with a frost-protected design — making it a practical choice where internal plant room space is limited.
Featuring a weather-proof PVC-coated casing and full insulation to minimise heat loss, the Silverpac is engineered for outdoor installation and long service life. Its patented heat exchanger and high-efficiency low NOx Elco burner help ensure clean combustion and whisper-quiet operation, while removable side panels and multiple tapping points make installation and servicing straightforward for contractors.
This model is part of Firebird’s proven range of oil-fired boilers, backed by a 5-year warranty (terms & conditions apply), and delivers balanced performance for homes requiring dependable heat and comfort through the colder months.
