The chain has launched an I am not a patio heater logo-ed blanket after banning sale of patio heaters from its 123 stores last Easter.
Wyevale marketing director Deborah Poll said the aim is to highlight the problems associated with using the heaters:
They are harmful to the environment because they consume so much energy and emit high amounts of carbon dioxide (CO2), so the idea is that we stop selling them and sell blankets instead. We hope people will start to wrap up instead of reaching for a gas canister to keep warm. The blanket would even make a perfect Christmas present.
The Energy Saving Trust says the CO2 emitted by 2.3 million patio heaters is the same as what would be released by driving from Lands End to John O’Groats 200,000 times.
Garden heater sales fell by 37 per cent from £11.19 million to £7.08 million between January and July 2007, the HTA has found.
