Hot Dawg H2O from Modine is an extension of the popular gas/propane Hot Dawg line. It's the first hydronic unit heater to have no moving external parts, making it a perfect fit for places like a garage or warehouse. The unit’s design and low profile allow it to be rotated for either horizontal or vertical air discharge, giving users multiple installation options.

Hot Dawg H2O comes in two models - the HHD30, operating at a range of 23,700 to 39,200 BTU/hour, and the high-capacity HHD45, operating at a range of 23,900 to 56,800 BTU/hour at 180F of entering water temperature. The HHD45 also includes a speed control which allows the user to receive a range of 425 to 710 CFM.
