ColdForge Chiller: Heating, Cooling & Chilling in One Unit Built for cold plunge tubs and Nordic baths, this chiller holds your water at the temperature you want, year round. It cools for recovery and cold therapy, heats when you want a warm soak, and runs as a heat pump rather than a straight electric heater, so it draws far less power for the same result. Every ColdForge chiller ships with a filter set included, so your water stays clean from day one. The titanium heat exchanger resists corrosion and is built to last in constant water contact. Integrated WiFi lets you set and check the temperature from your phone (iOS and Android), and it runs quietly enough to sit beside a tub without intruding. Compatible with virtually all spa and plunge systems. Why it matters Consistent water temperature is what makes a cold plunge usable every day instead of a chore. No refilling with ice, no waiting for it to cool, no guessing. Set it once and it holds. What you get Heats, cools, and chills from a single unit Runs as a heat pump for lower running costs than electric heating Titanium heat exchanger for corrosion resistance and long life WiFi control via app (iOS and Android) Digital display control panel Quiet operation
