Firebird Envirogreen Slimline Systempac External Oil Boiler

Firebird Envirogreen Slimline Systempac

The Firebird Envirogreen Slimline Systempac is an external condensing oil-fired system boiler designed to provide efficient central heating while keeping key system components integrated within the boiler casing. Manufactured by Firebird in Ireland, the Slimline Systempac is designed for installations where internal space is limited and an external boiler provides a practical heating solution.

Available in 12–20kW, 20–26kW and 26–35kW heating output ranges, the Envirogreen Slimline Systempac provides options for different residential and heating-system requirements. All three models have an A ErP heating rating.

External Condensing Oil Boiler

The Slimline Systempac is purpose-built for external installation and features a high-quality weatherproof casing with built-in frost protection. Its fully insulated construction helps reduce heat loss, while the compact 465mm width makes it suitable for locations where installation space is restricted.

The boiler incorporates a patented heat exchanger design and a high-performance low-NOx Elco burner. Its ultra-quiet operation makes it suitable for residential environments where reducing boiler noise is important.

Integrated System Boiler Components

Unlike a conventional heat-only boiler that requires separate system components, the Envirogreen Slimline Systempac is supplied with a factory-fitted expansion vessel and circulating pump. The boiler is also pre-plumbed and pre-wired, helping simplify installation and save installation space.

The Slimline Systempac is suitable for both open-vented and sealed heating systems, providing flexibility for different heating-system configurations.

Available Heating Outputs

The three models share a compact 960 × 465 × 760mm overall specification in the current Firebird product information.
