General Features

ECO5 BLUE

Baxi Eco5 Blue , the low NOx conventional boiler for replacement in branched collective flues.

The Baxi Eco5 Blue A7729074 conventional wall-mounted boiler with natural draught.

This traditional gas boiler is ideal for installation in branched collective flues. It provides heating and domestic hot water (DHW) with low consumption and emissions.

The ErP/EcoDesign regulation provides that, as an exception, manufacturers can continue to produce and market open-chamber, low-NOx boilers for domestic installation only, subject to the requirement to replace them in branched collective flues.
The Baxi B1 type conventional natural draught boiler ranges are specifically designed to meet all installation requirements in branched collective flues.

ERP Energy Labelling

The labelling regulation (EU Regulation 2017/1369) requires products to be labelled according to a decreasing energy scale from A++ to G, which will move from A+++ to F from 26/09/2019.

The energy class, identified by a letter, expresses a range of efficiency values ​​within which the product in question falls. The label was created to enable end consumers, by providing true and comparable data, to make informed choices about high-efficiency products.

Main features of the Baxi Eco5 Blue

- Low NOx emissions: class 6 according to EN 15502
- Compact dimensions 730x400x298 mm
- Control panel with multifunction LCD display
- Predisposition for combination with the Baxi integrated solar system
