Mini Boiler (3-5Kw)
Specific to Dry Heating / Small-capacity
Hien Instant Electric Boiler
Based on RAONIS’s Differentiated Technical Prowess
Long-lasting Warmth
TCM heaters can be used semi-permanently without any corrosion.
Hien boilers use the instant heating method without requiring a heat storage tank,
and demonstrates excellent heat resistance and corrosion resistance.

Central-heating methodradiation heat method
The radiation heat method
provides pleasantness without stuffiness.
TCM heaters radiate far-infrared rays(above 90%) and
use the radiation het method to evenly and
more efficiently warm up any indoor space.
It is more economical when used for dry heating.
Applying a Hien boiler to a dry heating system that uses diverse hot water panels
will cut down the electricity cost and enhance the financial efficiency.
A Hien boiler is perfect
for any house equipped
with a photovoltaic lighting system.
Installing a Hien boiler in a house equipped
with a photovoltaic lighting system contributes to
cutting down the heating cost.

and LPG gas, the heating cost can be reduced by 30%~40%.
Heating cost reduced by up to 55% compared to kerosene and LPG gas
Since the low maintenance cost increases use efficiency and extends heating time, it enables fuel saving.
Economic Feasibility of Instant Electric Boiler
* Based on an oil consumption of 20K, on a gas consumption of 20,000kacl/h, on an electricity consumption of 24k, and on the hourly fee rate applied to April 2018(kerosene: 907.48/L, LPG: 1,845.06/kg, based on general-purpose electricity high-pressure C light loading: 53.7won/Wh)
Its noise-free design offers quietness.
This product actualizes pleasant warmth in a small space,
and the combination between the canned pump method
and the SSR control(non-contact relay) method prevents rotation noise
and enables quite operation.
Multiple safety devices for precious people
