14-Plate Flat Type Combi Boiler Plate Heat Exchanger Compatible with Demirdöküm Baxi Ariston (166mm Screw Spacing)

Specially manufactured for technical services looking for fast response and ideal capacity in heating domestic hot water (DHW) in combi boiler systems, the 14-Plate Flat Type Heat Exchanger offers a definitive solution to hot water fluctuation complaints. Its standard 14-plate volume delivers optimum performance, especially in medium-capacity installations, while its 166mm screw (pin) spacing ensures a trouble-free fit with the hydraulic groups of the target combi boiler brands.

Wide Brand Compatibility and Durable Construction

It is designed to integrate fully with Demirdöküm (Aden etc.), Baxi, Ariston (Genus series) and Fondital combi boilers, which are among the most common appliances on the market. The 14 stainless steel plates joined with special copper brazing technology show superior resistance both to the pressure on the mains (secondary) side and to corrosion on the central heating (primary) side. The flat surface design makes scale build-up more difficult, extending the time before the heat exchanger clogs and safeguarding your service warranty.

Installation and Fault Note for Field Technicians

Technician Note: If your customer says "The hot water keeps going hot and cold" and the appliance has 12 or 14 plates, fitting this 14-plate model in its place restores hot water comfort to standard values. During installation, make sure that the 166mm pins sit fully and without strain on the hydraulic block. Always replace the original O-rings, and do not put the new part into service before flushing the system to remove any sludge/sediment residue that may have broken off the old heat exchanger and entered the 3-way valve block.
