PROBLEM TO BE SOLVED: To solve the problems of a conventional structure wherein a solenoid valve is automatically closed by action of a temperature sensor when an outer surface temperature of an LPG cylinder reaches 40°C, supply of hot water to a hot water jacket attached to the outer surface of the cylinder is stopped, and hot water is discharged to a hot water supply pipe by switching of the solenoid valve, and a conventional structure wherein a cover body for the LP gas cylinder in a size for storing a pair of the LP gas cylinders arranged along an outer wall in parallel is formed to be an almost box shape, and a plurality of strength reinforcement ribs in a shape of a recessed groove are disposed in a height direction. SOLUTION: The temperature rise preventing cover 4 made of incombustible or flame retardant cloth and covering an outer peripheral wall surface of the LPG cylinder as the single body is covered on the outer peripheral wall surface of the cylinder on the outer side of a ring member 3 fitted to an outer side of a cylinder shoulder part and the ring member 3 fitted to an outer side of a cylinder body part while having a clearance over the whole or the half of the circumference of the cylinder.
