Most frugal with high efficiency (High electromotive force) Original of Virgo is High of efficiency saving gas stove there are research and developed from the general stove by team of engineer. They were take the mechanics technical to adapted for rushing gas to pulled the air from beside and under base of stove including mixing between gas and air in the pipe line to used completely it has been became to completed burning, high temperature, decrease off lampblack and contamination it is using gas less 20-33%. Is saving gas stove was making with strong raw material, high qualities while will be save the natural gas also there are cheap with investment worthwhile. Special quality beyond abbreviate 20-33% of High temperature Decreased using nature gas Cleaning it salve within using period time Frugal guarantee within using period time Do not adjust base of air within using period time The piston ring for protection distributed temperature as beside Can take finish gas in tank more than general stove Complete burning, decrease lampblack on the ware Produced under copyright of designing and invention of Thai people and made in Thailand Head of stove can spirit level
