Heating boilers Navien GA/GST
The company “Kyung Dong NAVIEN” presents under the brand “NAVIEN” a double-circuit floor-standing gas boiler Navien GA / GST.
It has compact dimensions for a floor-standing boiler compared to other models.
Therefore, they are easy to transport and install.
Gas boilers Navien GA / GST in floor-standing design have two circuits, one of which provides heating and the second provides hot water.
The boiler is equipped with a special protective chip SMPS (Switched-Mode Power Supply) on a microprocessor, which protects the boiler from voltage surges in the network within ±30% of 230V.

At medium gas pressure, these boilers work perfectly, but for regions with low pressure it is not suitable, for this it is better to buy wall-mounted gas boilers Navien Ace.
The service life of heating boilers Navien GA / GST is very long, and the low cost of the heating boiler makes it an excellent option for an apartment, house or office, and the attractive appearance will not spoil the interior, but only emphasize it.
