With cooking-gas prices rising relentlessly, induction and infrared stoves are seeing boom in demand, Ho Chi Minh City electronic retailers said.

Nguyen Thi Ngoc Thuy, director of the household appliances section at dienmay.com, said "since the middle of last year, demand for these stoves has increased." In November sales was month-on-month up by 5-7 percent, she said.

A marketing staff from Thien Hoa Electronic Centre in the southern hub also told Viet Nam News that his chain sold an increasing number of induction and infrared stoves.

An article on a Ministry of Transport website quoted the head of marketing of online seller www.chodientu.vn as saying that electric stoves now accounted for 30 percent of all sales.

There are many kinds of induction and infrared stoves, both imported and made in Vietnam. Thuy of dienmay.com said her company sells many brands like Kangaroo, Media, and Electrolux.

"Price ranges from 490,000 VND (23 USD) to 2 million VND (95 USD). High-end stoves cost tens of millions of dong," she told Viet Nam News.

She predicted sales to continue rising in the coming months because Tet (Lunar New Year) is coming around and people need these stoves for cooking hot pots.

Sellers said induction and infrared stoves offered many advantages. Gas prices are high and the stoves are not as safe as induction or infrared stoves, they said.

Thuy said the latter helps save energy and money compared to gas stoves, is cleaner, and better looking. "When using an induction stove, consumers can use 95 percent of its energy. The figure is 80 percent for infrared stoves and only 60 percent for gas stoves."

Talking about the future of gas stoves, most sellers said though many people were buying induction and infrared stoves, gas stoves would remain essential in Vietnam due to power cuts.

Thus, many customers are now choosing to use both gas and induction (or infrared) stoves at the same time, they said.

Retail gas prices increase 80,000 VND to 485,000 VND per 12kg canister from December 1, posting the record high since February 2012, causing difficulties for both gas traders and household consumers.

To help lower the price, the Vietnam Gas Association sent a request to ministry to reduce the current 5 percent tariff to zero percent so retail prices will fall by 17,000 VND (80 cents) a canister.

While the Ministry of Industry and Trade also supported the association's request, the finance ministry did not think it was the correct time for a tariff adjustment.-VNA
