The image shows a close-up of a water heater installed on a concrete wall. The water heater is made of metal and has a cylindrical shape. It has a black and yellow label on the front with the brand name "Cerberus" written on it. There is a small motor attached to the side of the water heater, which is connected to a hose that runs from the top to the bottom. The hose is coiled up and appears to be in good condition. The wall behind the heater is also made of concrete and is painted in a light brown color.
