【Outdoor installation to save space】The product is installed outdoors and does not occupy the living space. The bottom built-in forced DC fan eliminates the influence of external wind. So as to ensure the stability of combustion, achieve safety, energy saving and no pollution. We recommend that all installations are carried out in accordance with local building and plumbing codes by licensed professionals.

【Endless water supply without preheating】The heat exchanger quickly heats the water to a maximum of 140°F, which is ready for use without waiting for hot water. It can run at approximately 6.3 GPM for 40 minutes, enough to produce almost 240 gallons of hot water. Make a multi-point water supply for the whole house to meet your family's water needs.

【Precise temperature control and stable temperature】Equipped with a wire controller cord length of 164ft, allowing you to control the water temperature indoors. The burner can be burnt in sections to meet the water temperature demand in the four seasons. Benefiting from the calculation and control of the heating power 1000/s by the chip, the temperature difference of the water can be precisely controlled within ±2°F.
