Combined
GALMET combined tanks are modern "tank-in-tank" solutions that combine the function of a central heating buffer and a domestic hot water tank in one device. Thanks to versions with 1 or 2 coils, as well as variants without coils, they offer maximum installation flexibility and the ability to work with various heat sources, including boilers, heat pumps and solar systems. In our offer you will find insulated combined GALMET buffers in capacities from 300 L to 1000 L, which provide energy savings, user comfort and stable operation of the entire heating system.
What are GALMET combined tanks?
Combined tanks are innovative "tank within a tank" devices that combine heat buffers with a domestic hot water tank in a single unit. They allow you to store thermal energy in the central heating system while providing immediate access to hot tap water.
The GALMET insulated combined models are available in the following variants:
-
with 1 coil – connection of e.g. a boiler or heat pump,
-
with 2 coils – ability to integrate an additional heat source, e.g. solar collectors,
-
without coils – serves as a heat buffer, simple and universal.
Such a solution increases the energy efficiency of the installation, allows you to reduce fuel or electricity consumption and simplifies assembly.
Available models and capacities
We offer a full range of insulated GALMET combined tanks, including:
-
Buffers 300/80, 380/120, 500/160, 600/200, 800/200, 1000/200 – capacities adapted to various installations.
-
Versions with 1 or 2 coils – flexible connection to heat sources and water heating.
-
Versions without coils – ideal as universal heat buffers.
Thanks to factory insulation, all models minimize heat losses and improve the energy efficiency of the entire installation.
