Bad burner policy

ECan’s Katherine Trought (Jul 20) is wrong to say that a refurbished sub-1 gram/kg woodburner would need to be laboratory tested. If the manufacturer of a burner were to refurbish a stove back to the ‘‘asnew’’ condition of when it was originally tested to the national environmental standard, there is no legal reason for it to be retested or logical reason for ECan to prohibit its use.

The idiocy of ECan’s policy is that under its existing rules a perfectly serviceable 20-year-old 0.3-gram/kg low-emission burner must be replaced and can be replaced with a more than threetimes-dirtier 1-gram/kg stove. Paul Sintes Lansdowne, Canterbury
