WHAT CAN ZUBA MEAN TO YOU?
Now you can experience the year-round comfort, savings, quality and reliability you deserve. The secret behind Zuba’s superior heating capabilities is our
efficient and patented Cold Climate Hyper-Heat (H2iTM) technology. Designed for the Canadian market, Zuba operates at
100% heating capacity at -15°C and continues to deliver exceptional heating performance when the outdoor temperature drops
as low as -30°C* and beyond. The unique defrost mechanism provides an extended period of continuous heating between defrost cycles and minimizes the defrost time required.
