Description
Ideal 175419 16 Plate Heat Exchanger 35kW
The Ideal 175419 plate heat exchanger is a compatible 16-plate replacement for selected 35kW and related Ideal combi boilers. It fits popular ranges including Ideal Logic, Logic+, Isar, Independent, Combi, Code and Ultra.
It is also listed for the Keston Combi 35.
The plate heat exchanger transfers heat from the boiler’s primary circuit into the domestic hot water circuit. Therefore, efficient heat transfer is essential for reliable hot water performance.
This compatible replacement offers a practical and competitively priced alternative for engineers replacing a blocked, scaled or faulty plate heat exchanger.

What Does a Plate Heat Exchanger Do?
A plate heat exchanger transfers heat between two separate water circuits without mixing them.
In a combi boiler, hot primary water passes through one side of the plate exchanger. Cold mains water passes through the other side and absorbs the heat.
Therefore, the plate heat exchanger plays an important role in producing domestic hot water.
Professional Installation Recommended
The plate heat exchanger forms part of the boiler’s hydraulic system.
We recommend installation by a suitably qualified heating professional. The system should also be checked for contamination, scale and circulation problems that may have contributed to failure of the original exchanger.
