Hot Water Cylinders

Hot Water Cylinders, Indirect Water Heaters, Calorifiers & Buffers for Commercial Buildings

Adveco provides a range of commercial-grade hot water cylinders for various DHW applications.  Indirect-fired water heaters, calorifiers and buffers are designed for projects requiring large volume storage of water at high temperatures. An additional primary heat source, such as an electric water heater or gas boiler, is needed. Working as a buffer and storing the hot water, calorifiers and buffer tanks reduce the operational demand placed on the primary heat source saving energy, reducing costs and lowering emissions.

As there is no fluid mixing during thermal transfer indirect water heaters and buffer tanks allow for heat transfer from other fluids including that used in solar thermal collectors and air source heat pumps. This unlocks multiple options for bespoke hybrid DHW application development in commercial buildings.
