A compact installation of a hydronic heating gas boiler upgrade, featuring the highly efficient BAXI Duo-Tec E Natural Gas boiler. This upgrade was done to replace the outdated traditional atmospheric gas combustion boilers at a large 4 bedroom residence in Melbourne's Bayside.

The existing system of two boilers had reached its end of life, and this afforded the owners the opportunity to upgrade to a state of the art hi-efficiency system. After consultation a BAXI Duo-Tec E gas condensing boiler was chosen to do the job. The system powers 14 hydronic radiators spread throughout the home and also heats the potable hot water supply for domestic consumption (DHW) through a separate calorifier tank.

The Co2 output reduction achieved compared to the previous system was massive, as well as the new BAXI system providing huge improvements in energy usage and cost savings of around 30%. A hi-efficiency gas condensing boiler such as the Duo-tec E is arguably the most energy efficient option available to heat your home, and in addition Baxi Duo-tec boilers are also Green Hydrogen blend capable right now, so you can future proof your home as well.

The BAXI Duo-Tec E has a 1:7 modulation ratio which means the boiler turns itself down to only provide the energy needed to match the required heat output. This greatly improves boiler efficiency and lifespan by avoiding boiler on/off cycling and only using the energy needed to heat the home when it is required.

To get an idea of the compact boiler installation and connecting piping system view the image gallery and the short video walk through. The piping fit-off and insulation which can clearly be seen is also an integral part of an efficient heating installation to avoid unnecessary heat loss.

If your hydronic boiler is starting to struggle and under perform, it is likely that it's time for an update. BAXI boilers are neater, easier to use and quicker to install than competitors. Regular servicing also then ensures that your BAXI hydronic heating system operates reliably and efficiently all year round, year in, year out.
