Duo-Tec E Compact

The Baxi Luna Duo-tec MP/MP+ is a range of heating-only gas condensing boilers designed for medium and large heating systems. Outputs run from about 50 kW up to 150 kW per unit, and up to 6 boilers can be linked in cascade for bigger projects. A stainless steel heat exchanger, a wide 1:9 modulation ratio and a built-in modulating pump give up to 107.8% efficiency (ErP class A) with low running costs. Advanced digital controls support multiple zones, scheduling and 0–10 V building management integration. It runs on natural gas or LPG and suits apartment blocks, hotels, schools and commercial buildings.
