Icy weather this winter, including an exceptionally cold snap in late June, had some Kiwis looking to warm up however possible.
With some models sold for as little as $30, the blankets could be a cheaper option than heaters.
He said a few basic measures could enhance safety for those using the blankets.
Sometimes frayed or kinked wires in blankets brought out of storage were a safety risk.
Mr McEnaney said people should roll up electric blankets, not fold them.
He said some people forgot to turn blankets off when they woke up, or left objects on top of the blankets which could ignite.
Mr McEnaney said he knew of times when baskets full of washing caused fires after being left on electric blankets.
If you notice your cat or dog suddenly leap off the bed, they may be about to catch fire from the electric blanket -- it sounds odd, but apparently does happen.
"Animals can do it too. If they lay in the one place for long enough, then it gets that hot...It's that constant heat in the one place," Mr McEnaney said.
Wheat bags were also a potential fire risk if not handled properly.
"Again, if people put them in the microwave, and they overheat them...they continue to heat up," Mr McEnaney said. "They don't just stop heating up when the person pulls it out of the microwave. And if it's covered, under a bed or under a blanket or pillow, then there's no airflow so it heats up."
The Ministry of Consumer Affairs said people should read and follow manufacturers' instructions and avoid over-heating wheat bags.
"The recommended maximum is three minutes for manufactured bags," the Ministry said on its website.
"Watch for an over-cooked odour, a smell of burning, smoking or charring. Do not use the bag if you observe any problems - contact the manufacturer."
Adding oils to wheat bags creates an added fire risk, the Ministry added, and people should not store wheat bags until they were cold.
