Tanks without an exchanger

Tanks without an exchanger are used to store hot water. They are used wherever the heat source is variable, e.g. with wood gasification boilers, or with solar energy, or with heat pumps. Their advantage is that they can "store" heat, and then when heating is required, this heat is used for heating or DHW heating. A suitable source can be a solid fuel boiler, heat pump, solar collectors, but also a fireplace insert. The insulation is made of polyurethane foam covered with polyester fabric. The insulation is supplied separately and must be ordered separately.
