At the core of NESTA Chrome boilers is our stainless steel Fire Tube heat exchanger. The use of high-grade stainless steel alloys ensures product durability, reliability, and higher resistance to corrosion and oxidation.

Our unique Fire Tube design of Nesta Chrome heat exchangers is a market proven technology, manufactured and distributed worldwide for many years. Our commitment to improvement and advancement in design has produced one of the most efficient boilers in its class.


Fire Tube heat exchanger

One of the major advantages of NESTA Chrome Fire Tube heat exchanger is the self-cleaning feature. The unique design and orientation of the heat exchanger allows the condensate to run down the inside of the heat exchanger tubes and cleans any possible traces of combustion residue. This function allows the boiler to maintain maximum efficiency throughout the lifespan, leading to reduced running costs and maintenance for the end user.
