Heat transfer
Preparing a hot-water cylinder or storage tank quotation request
Describe the heat source, application and hot-water demand before discussing a hot-water cylinder or storage tank.
Distinguish between heating and storage requirements
Our hot-water cylinders are available in single-coil, twin-coil and electric versions. Hot-water storage tanks are used for storage in central hot-water systems. Describing the existing system or new project helps identify which product to discuss.
- The system application and hot-water demand
- The existing or planned heat source
- Storage requirement and design temperatures, if known
Share the installation details
If you are replacing existing equipment, connection and installation dimensions are useful. For new projects, you can send the piping diagram and the values in the specification.
- Installation space and access dimensions
- Connection points and a piping diagram, if available
- Material requirements or other project conditions
Do not assume values that have not been calculated
Capacity, output and temperatures are assessed according to the project requirements. This guide is not a sizing calculation. You can share your needs and the information available via WhatsApp or email.
