The extremely compact dimensions make this boiler particularly ideal for replacing old natural draft generators connected to branched collective flues, the only installation context allowed by the ErP directive for traditional open chamber boilers. The ErP/EcoDesign regulation in force since 26 September 2015 has forced manufacturers to place on the market products equipped with a high-efficiency pump (since 1 August 2015), which comply with the eco-compatible design requirements and bear an energy label. The legislation also provides that by way of derogation, producers can continue to produce and commercialize ONLY open chamber boilers for installations in domestic contexts, with the restriction of replacement in branched collective flues. Baxi's ranges of conventional B1-type natural draft boilers are precisely designed to meet all installation requirements in branched collective flues. Characteristics: Low NOx and CO emissions: class 5 according to EN 297 and EN 483 already compliant with the legislation that will come into force in 2018 Hydraulic group in brass Control panel with multifunction LCD display STANDARD climate control (with optional external probe) Arrangement for combination with the Baxi integrated solar system High efficiency circulation pump Antifreeze function and IPX5D degree of protection Product Guarantee All products for sale on our site are new and packed.
