Buffer vessels, tanks, boilers for heating, heating to boilers
Buffer tanks are used to store hot water. They are used wherever the heat source is variable, e.g. for wood gasifying boilers or solar energy, or for heat pumps. Their advantage is that they can 'store' heat and then, when a heating demand arises, this heat is used for heating or DHW. A suitable source can be a solid fuel boiler, a heat pump, solar collectors, or a fireplace insert. Storage vessels are available in three variants. Type ZG from 850L to 3000L is just an ordinary heating water container. Type ZGI from 850L to 3000L with one heating exchanger and type ZGIB from 850L to 2200L with one exchanger and with 200L DHW tank. The insulation for the storage vessels is made of 100mm polyurethane foam covered with polyester fabric. The insulation is supplied separately and must also be ordered separately.
