Different metals have different properties, such as weight, corrosion resistance and heat conductivity which also have an impact on the heat exchanger design, for example, the size of the waterways. While one heat exchanger type can be suitable for one building, it might be unsuitable for another.

Stainless steel is an alloy of iron combined with chromium (min. of 10.5%) to make it corrosion resistant and lower carbon content compared to cast iron. Grade 316 is the most common type, with good welding and heat transfer properties, similar to those of cast iron. Compared to aluminium, stainless steel is tolerant towards a wider pH band (7-9.5), making it suitable for more challenging water conditions. Wetter environments such as swimming pools can especially benefit from these properties. Given its durability and longevity, warranty terms are often favourable (5-10 years); for instance, ModuMax Mk3 comes with a 10-year warranty.
