An electric space heater was the cause of a house fire that destroyed a St. Albert home on Boxing Day, causing over $750,000 worth of damage.

"As with any electrical appliance they are always subject to failure," said Les Mroz with St. Alberta Fire Services.

The fire started in the garage of the Dorchester Drive home just before 9 p.m. Wednesday.

Flames soon spread to the roof and inside the house.

Two people were inside the home at the time, but both were able to get out safely.

Mroz said electric heaters are a serious fire hazard this time of year.

"The big thing is to make sure it is [Canadian Safety Association] approved. Coming from a reputable company, following the manufacturer's instructors and not placing those heaters close to combustible materials," he said.
