With hot water preparation - Water Heaters and Storage Tanks

Storage tanks for hot water preparation, suitable for many types of heating systems including heat pumps.

Depending on the temperature of the heating water that is accumulated in the tank, the connection with the boiler allows DHW heating in the inner reservoir to the required temperature. On the other hand, connecting to solar collectors or a heat pump will only preheat DHW, and it will be necessary to include an additional (for example, electric) water heater, which will heat the water to the desired temperature. Electric heating, provided by either the TJ 6/4" electric heating unit or the TPK heating flange, can be installed into the storage tank.

More information

More information about the NADO and NADOS storage tanks

Storage tanks serve to accumulate excess heat from its source, which may be
- solid fuel boiler
- heat pump
- solar collectors
- fireplace insert, etc.
Some types of tanks allow combining and wiring multiple sources of heat
NADO and NADOS tanks allow water to be heated in the inner enameled vessel or the stainless-steel exchanger. Steel tubular exchangers for instantaneous heating cannot be used!
Incorporating a storage tank into a heating system with a solid fuel boiler allows the boiler to run at optimum temperature
To increase the service life of the tank, we recommend using treated or distilled water as the heating medium. We also advise adding products that limit corrosion (inhibitors)
The storage tanks are equipped with a removable 80 mm thick insulation.
