Baxi Luna Duo-tec+ Compact Combi Boiler 28kw

Upgrade your home's heating and hot water system with the Baxi Luna Duo-tec+ Compact Combi Boiler 28kw (Model 28 GA). Designed for modern New Zealand homes where space and energy efficiency are top priorities, this premium gas condensing boiler delivers powerful hydronic central heating and continuous, high-pressure domestic hot water from one highly compact, wall-mounted unit.

Revolutionary Gas Adaptive (GA) Technology for Effortless Installation

For trade professionals and gasfitters across New Zealand, the Baxi Luna Duo-tec+ is a game-changer. Equipped with an advanced gas adaptive valve, this boiler automatically configures itself to the correct gas type, making traditional flue gas analysis obsolete. Commissioning is as simple as powering up the unit and pressing 'OK' when the gas type is displayed on the screen. This innovative feature slashes installation times and takes the headache out of commissioning on site.

Engineered for High-Efficiency Kiwi Home Heating

Whether you are planning a new build or upgrading an existing home heating system, the Baxi Luna Duo-tec+ offers industry-leading performance. Featuring a 1:7 gas valve modulation ratio, the boiler continuously adjusts its output to match your home's exact heat demand. This prevents short-cycling, reduces wear and tear on components, and significantly lowers gas bills. The robust stainless steel heat exchanger ensures maximum thermal transfer and long-term durability in New Zealand conditions.

Important NZ Compliance & Consenting Information

Baxi Combi boilers come standard with an integrated fill valve to enable easy top-ups of the central heating circuit water levels. Please note that some New Zealand local councils require this mains water connection to be removed or blanked off during the building consent process. Your certifying gasfitter or plumber may need to blank this connection to comply with your local council's specific regulations.
