This article is primarily aimed at those living in the state of Tasmania (that little island south of Australia) and thus it quotes our rules under the Environment Protection Act. If you are elsewhere, you’ll need to read up on your local regulations.
When we moved to Tasmania in late 2013, we deliberately chose a house with a wood heater. We assumed – O silly us! – nice dry firewood would be easy to come by. Unfortunately we’ve had several rather rude awakenings and reminders.
All this argy bargy led us, 2 years ago, to purchase a wood moisture meter. I strongly believe every buyer of wood, who this is really aimed at, should insure themselves by having one and carrying it every time they take delivery of a load of wood. But they are very useful for sellers too, you can be confident you have a good product and no repercussions will come back to haunt you!

First, our experiences
Towards the end of winter 3 years ago we purchased a large load (app 2 tonnes) of wood to see out the season and have a bit on hand for those cold summer spells we experience in Tasmania. We tried to burn it and just got a sullen fire and a blocked chimney for our trouble, despite the fact the chimney had the annual clean sweep in mid summer. So when the seller proved un-contactable via his previously quickly answered mobile – surprise, surprise – we had to (a) buy more wood; and (b) keep the green wood until next season. This led to the purchase of our moister meter.
During this season we changed our old wood heater for a modern model with an oven under the firebox and room on top for 5 kettles and pots – and our winter power bill dived. But the quality of the wood became even more important.

The next year we found what we thought was a very good wood merchant, despite the fact his delivery lead times were all over the show, and had a good winter until about September, when suddenly, the wood was wet. Upon contacting him, he was very belligerent and unpleasant so we gave him the shove too and bought in from the supplier we knew would let us test first, but paying a very premium price.

This year started well. A neighbour had fabulous wood as he worked for a wood merchant, the price was good, we started laying in supplies in February . . . then, in May, disaster! He changed jobs and we were once again without a wood merchant. I tried a large firm that advertises on their trucks, on social media and elsewhere. He brought us a load of wood for a fair price but, when we started stacking, it felt very cold and very heavy. Over 2/3 of it tested more than 35% moisture, the generally accepted optimum is 18-22%. On contacting him, he did come out and agreed to replace it, but made some ridiculous statements regarding the burning qualities of wood, and a sling that 2 prong meters weren’t much good etc, leaving me to believe either he thought we were fools, or he was one. But he did replace the wood.
During all this a chap contacted me via FaceBook and said he was happy to bring a load of wood, same amount and price as the wet wood previously offered, and I could prong it with the meter prior to unloading. We went on this basis and the wood is wonderful, so hopefully we have someone who will keep supplying us.
About moisture meters.
A firewood moisture meter can take the guesswork out of trying to determine if your firewood is seasoned (dry enough – under 20% – to burn efficiently) or not. While both pin and pinless meters are available, in homeowner/occupier terms, the 2 pin type will be what you choose, simply due to cost. The simpler 2 pin meters are from $10-$30, while the pinless ones, which are a bit trickier to measure correctly with, are from $60 upwards.
The 2 pin ones work by passing a charge between the 2 pins through the wood. The pinless ones have a sensor pad which send an electrical charge into the wood and measures the resistance. The whole pad must be in contact with the wood, which can make it difficult to get an accurate reading from rough textured firewood.
The only disadvantage of the 2 pin ones is they only measure a short way into the wood. If in real doubt, split a couple of pieces and measure at the split sites. If you have very large pieces of wood, you’ll need to measure it in several places.

Why have a Moisture Meter
There’s a few reasons. It will save you money, both on the wood you buy – green wood is far heavier so if paying by weight you’re getting ripped off – and you can actually be in deep trouble with the authorities (see below) if you burn wood producing a lot of emissions – smoke and particles.
It can also be hazardous to burn green, or wet, wood. This wood does burns at a lower temperature because the moisture in it lowers the temperature of the fire. This means deposits of creosote may build up in your chimney or flue, and can result in a chimney fire, often a very serious fire as it spread through the roof cavity. You’ll also be up for more frequent chimney sweeping, thus costing your more on maintenance.
Under Part 3, Section 9 of the Environmental Management and Pollution Control (Distributed Atmospheric Emissions) Regulations 2018, passedby the Governor on 23 January 2018, and reproduced below, the occupier is responsible for all emissions from their wood heater. You can be fined if your appliance is not operating properly and are producing damaging emissions (smoke). Therefore it is in YOUR interests to ensure you get the most suitable fuel available – dry, seasoned wood.
PART 3 – EMISSION OF SMOKE FROM HEATERS, FIREPLACES, BARBECUES, &C.
- Emission of smoke from heaters, fireplaces, barbecues, &c.
(1) A person who is the occupier of a building or land is not to cause, or allow, to be emitted, from a heater, fireplace, barbecue, hot water heating appliance, cooking appliance, or heater or appliance specified in regulation 4(1), smoke that –
- (a) is visible for a continuous period of 10 minutes or more; and
- (b) during that continuous 10-minute period, is visible for a continuous period of 30 seconds or more –
- (i) in the case of a heater, fireplace, barbecue, hot water heating appliance or cooking appliance in a building, at a distance of 10 metres or more from the point on the building where the smoke is emitted; or
- (ii) in the case of a heater, fireplace, barbecue, hot water heating appliance or cooking appliance that is not in a building, at a distance of 10 metres or more from the point where the smoke is emitted.
- (2) If an authorized officer or a council officer is of the opinion that a person who appears to be the occupier of a building or land is contravening subregulation (1), the officer may serve a written notice on that person requiring him or her to take action, within 21 days after the day on which the written notice is served on him or her, to reduce the emission of smoke from the heater, fireplace, barbecue, hot water heating appliance or cooking appliance so that it complies with that subregulation when in use.
- (3) A person served with a written notice under subregulation (2) must comply with that written notice.
Penalty: Fine not exceeding 10 penalty units.
Does the Abbott Government have a Moral Compass?
The Moral Compass
It seems to me they fail on all parameters – at the moment we are at Chaotic Evil, I’d say. What happened to the tenets of Honesty, Integrity, Responsibility, Compassion/Kindness, and above all, do no harm and leave a positive legacy for future generations?
