Firebird Envirogreen Combi HE Condensing Oil Boiler

Firebird Envirogreen Combi HE

The Firebird Envirogreen Combi HE is a high-efficiency condensing oil-fired combination boiler designed to provide central heating and domestic hot water from a single appliance. It is part of Firebird’s Envirogreen condensing boiler range and is available in three heating-output ranges: 12–20kW, 20–26kW and 26–35kW. Firebird’s ErP documentation lists the Combi HE range across all three output sizes.

The Envirogreen Combi HE is designed for installations where an integrated heating and hot-water solution is preferred. By combining the boiler and domestic hot-water functions in one appliance, it can eliminate the need for a separate hot-water cylinder in a typical combi installation.

Firebird Envirogreen Combi HE Models

The range consists of three models:

Firebird’s ErP support documentation specifically lists Envirogreen Combi HE 12–20kW, 20–26kW and 26–35kW models.

The UK SAP product database also identifies the 20kW, 26kW and 35kW versions as Firebird Envirogreen Combi HE Condensing Boiler products using heating oil.

Condensing Oil Boiler Technology

The Envirogreen Combi HE uses condensing technology to recover additional heat from the combustion process, improving the useful efficiency of the heating system.

Firebird’s Envirogreen range incorporates a patented heat-exchanger design and high-performance burner technology. The boilers are designed to provide efficient heating while maintaining reliable domestic hot-water production.

The Combi HE range is listed by Firebird within its Envirogreen/Silver condensing boiler product documentation.

Central Heating and Instant Hot Water

As a combination boiler, the Envirogreen Combi HE provides both central heating and domestic hot water without requiring a conventional separate hot-water storage cylinder for normal combi operation.

The larger output versions are particularly suited to properties with greater heating and hot-water requirements, while the lower-output model provides a more compact capacity option for smaller heating loads.

The range is classified as a combi boiler using heating oil, rather than a regular or system boiler.

Firebird’s current product documentation groups the Combi HE with the wider Envirogreen condensing boiler range.

Compact Heating and Hot-Water Solution

The Envirogreen Combi HE is designed to provide a complete heating and domestic-hot-water solution in one appliance. This makes it particularly useful for homes where installing a separate hot-water cylinder would take up additional space.

The appliance is designed with service access and installation practicality in mind, helping installers carry out routine servicing and maintenance efficiently.

Hot-Water Performance

Domestic hot-water performance varies according to the selected boiler output.

The higher-output 26–35kW version is designed for greater hot-water demand than the smaller 12–20kW model. When selecting the boiler, the required central-heating load and expected domestic-hot-water demand should both be considered.

The Firebird Envirogreen Combi HE range is officially classified as a heating-oil combi product across the 20kW, 26kW and 35kW output classes.
