Boiler Blowdown & Water Treatment
Why blowdown happens, its energy cost, and how to minimise it.
9 min read
Blowdown is purposely draining hot water from the boiler to remove dissolved minerals before they form scale. If you don't blow down, the boiler gets encrusted with hard scale that insulates the water from heat and reduces efficiency. But blowdown has a real energy cost, and many boilers blow down far more than necessary.
