Abstract
A hot beverage brewing apparatus including a pressurized hot water delivery system to provide liquid under pressure within a range of acceptable infusion temperatures without a water pump. A fresh water tank is situated above a water heater in liquid communication to maintain the water heater filled. Water in the water heater is kept at a pre-infusion temperature. When infusion process is to commence the user selects volume of water to be dispensed into infusion material, water is rapidly heated to infusion temperature and displaced from water heater by pressurised air from air pump. At the end of the brew cycle the air pump is stopped and a valve connects the water heater to atmospheric pressure to facilitate water flow from the fresh water tank into the water heater. After the infusion process an air valve may direct air from the air pump to the infusible material to dry it for ease of disposal.
