Indirect / Calorifiers

In addition to our established gas water heaters, we also offer a range of indirect solutions, including indirect hot water storage calorifiers. We have a range of options including single coil and twin coil models. These products can be used as part of a heating boiler installation to provide domestic hot water, or can be used as preheat vessels when installed on a renewable project. We also offer a range of packaged plate heat exchangers, which can also be installed with one of our direct storage vessels for peak demand applications. Our Indirect water heater/calorifier products are suitable for a range of commercial and industrial applications.
