Next time you are looking to replace your boiler you probably won’t even consider how the heat exchanger is made, but here’s why we would recommend Stainless Steel.

Heat Exchangers: Stainless Steel v’s Aluminium

STAINLESS STEEL HEAT EXCHANGERS:

Used by Viessmann throughout its entire condensing boiler range, stainless steel heat exchangers provide a high resistance to corrosion in a wide variety of pH levels, therefore increasing the useful life of your boiler. This provides long term value for money and requires less system downtime due to maintenance.

Important points to consider:

Increases useful life of your boiler.
Less downtime due to maintenance.
Does not require use of system inhibitors.
Self-cleaning
Higher grade corrosion resistant material

ALUMINIUM HEAT EXCHANGERS:

A lightweight and alternative option, Aluminium heat exchangers also provide high heat transfer but require special inhibitors when maintaining the system, which if not used can result in a high risk of damage to the boiler. Annual maintenance is also vital to remove aluminium oxides, which can build up and clog the condensate line.

Important points to consider:

PH treatment critical to longevity of the heat exchanger.
Artificially softened water not permitted.
Aluminium material corrodes through aluminium oxide build up and erodes further at high flow rates.
Reduced lifetime of the heat exchanger.
Cheaper to manufacture than stainless steel. ...
