Heat recovery in a factory set up is very important. Most company releases condensate to environment instead of trapping it to boiler which saves the cost of heating up cold water every morning you start up your boiler. Case scenario where client requested for a quotation to fabricate 6000litre tank and 2000Litres solar water heaters. Solar were to heat water and then stored in the 6000litres tank later to be used to fill his boilers. After discussion we agreed to collect condensate from all the machine and back to condensate tank to be used by the boilers. After installation he realized he was saving on water that was consumed by the boilers and firewood intake reduced. That is why Wilest, is known for energy solutions.
