The number of patio heaters in gardens in Britain is expected to almost double over the next year, despite environmental fears, a report suggests.
The Energy Saving Trust says the number of privately owned units in the UK will rise from 1.2 million to 2.3 million.
After interviewing 1,192 UK households, it estimates that each heater uses the same amount of energy in six months as a kitchen gas hob does in a year.
Chief executive Philip Sellwood said: "Why don't people just wear a jumper?"
Researchers found that Yorkshire and Humberside had the highest rate of current or intended patio heater owners, on 18%.
The lowest rate was in the East of England, on 3%.
Two-thirds of patio heater owners said they used theirs once or twice a week.
Half of owners switched theirs on during the hottest months of the year, July and August.
Mr Sellwood said: "We are calling for responsible retailers to reconsider the sale of patio heaters in light of the substantial amount of carbon emissions they produce."
It is thought that the recently imposed smoking ban in enclosed public places in England will lead to more outdoor smoking and an increase in commercial patio heaters.
Mr Sellwood said: "People are also influencing the larger, more damaging commercial sector, with a third of pub-goers choosing pubs where there is a patio heater.
"Landlords are helping to make patio heaters desirable - which they are not."
Some 31% of people who responded to the survey said they liked to sit outside pubs and would choose one with outdoor heating.
Last month, London Mayor Ken Livingstone called for a halt in the spread of "wasteful" patio heaters and urged retailers not to promote them.
