Combined insulated Heat buffer GALMET 1000/200 (vessel within vessel, with 2 coils)
Kumulo is a storage tank with two spiral coils. Use of this tank is the most efficient way to quickly heat up domestic water while supporting central heating. Design of tank type in tank allows to store heat from different sources and exchange it between central heating and hot water systems. Combined tank Kumulo is offered in a lightweight, grey plastic housing type: skay/PVC.
Hot water exchange and central heating buffer have been combined in a combined storage tank, which will allow significant space saving. Domestic hot water tank is located in the upper part of domestic hot water storage tank and contains a large, feedable spiral coil. In the lower part of storage tank there is a black steel solar coil to connect solar collector. Heat for buffer can also be supplied directly from central heating boiler, fireplace or heat pump. Kumulo also has possibility of additional supply through GE electric heating set.
Accessories:
- Copper coil, corrugated with increased heat transfer surface, for installation in external tank.
- GE electrical sets with heater and controller.
- Temperature sensor covers.
- Open-system equalisation vessels for central heating systems, painted (optionally also insulated).
Advantages:
- One device, working as a hot water exchanger and a hot water buffer.
- Possibility to be powered from several heat sources.
- Simultaneous heating of water in both installations.
- Heat exchange between tanks of a hot water and heating system.
- Lower coil dedicated for solar collectors.
- Saving space in boiler room.
- Ceramic enamel EXTRA GLASS and magnesium anode.
- Capacity: 300/80 - 1000/200 litres.
- 5-year warranty
