The utility model discloses a high-power full-premixing condensing furnace and a heat supply system thereof. The condensing furnace comprises a shell, a full-premixing burner, a heat exchanger assembly, a fan, a premixer, a water supply pipeline, a water return pipeline and a control system, the heat exchanger assembly is provided with an automatic exhaust valve which is arranged on the top of the shell in a penetrating mode. And the premixer is provided with an air filter and a gas valve. According to the high-power full-premixing condensing furnace, important parts such as the full-premixing combustor, the heat exchanger assembly, the fan and the premixer are reserved, structures such as the water pump and the water tank are arranged externally, the overall structure of the furnace body is reduced, installation is more convenient, meanwhile, the automatic exhaust valve is arranged, and the problem that air is difficult to exhaust completely due to more groups of heat exchanger coils of the high-power conden
