## Long description

Vertical domestic hot water (DHW) heat exchanger Galmet MAKS 200 L (DWZ) is a tank-type exchanger with an internal spiral coil designed to provide sanitary hot water. The unit stores approximately 200 litres of potable water and transfers heat from an external heating source through the integrated spiral heat exchanger. The vertical configuration and insulated outer shell are engineered to optimise heat retention while allowing connection to boilers, heat pumps or other hot water sources.
Advantages
The spiral coil design ensures effective heat transfer between the primary heating circuit and the potable water stored in the tank, reducing temperature stratification and enabling consistent delivery of domestic hot water. The vertical layout minimises floor footprint and facilitates installation in mechanical rooms or utility closets. Constructed for potable water use, the tank and coil materials meet hygienic requirements for sanitary hot water storage and enable straightforward maintenance over the service life.
Suitable for
Residential hot water systems for single-family homes
Small commercial buildings with moderate hot water demand
Systems using boilers, heat pumps or solar thermal as primary heat sources
Retrofit projects where an insulated vertical storage tank with coil is required
Key specifications
Nominal storage volume: approximately 200 litres of potable water
Internal heat exchanger: spiral coil for primary circuit heat transfer
Mounting orientation: vertical tank design to reduce footprint
Insulation: factory-applied thermal insulation to limit standby heat losses
Connections: dedicated inlet and outlet ports for potable water and primary heating circuit
Application: designed for sanitary hot water production with external heating sources
How to use
Install the Galmet MAKS 200 L (DWZ) in a dry, ventilated space on a level surface, ensuring adequate access for pipe connections and service. Connect the spiral coil to the primary heating source (boiler, heat pump or solar loop) following hydraulic and safety regulations. Connect potable water supply and hot water distribution lines to the designated tank ports. Commission the system by filling and venting both the primary and domestic circuits, then run the heating source until the tank reaches the desired temperature. Follow local codes for pressure relief, expansion protection and water quality treatment.
Usage recommendations
To maintain efficient operation and sanitary conditions, regularly inspect connections and insulation, flush the potable water tank periodically if required by local water quality, and follow manufacturer guidance for corrosion protection and anode maintenance if applicable. Use appropriate controls to prevent overheating and ensure safe pressure levels in both primary and domestic circuits.
