Becoming a WETT inspector

'Round here, everyone and their uncle heat with wood. Being WETT certified would be a benefit up here. I had a call to go to Parry Sound just to do a WETT inspection. Turned it down, too far for too little.

You only need WETT if you want to do inspections for insurers or for home insurance reasons. There is nothing stopping you from calling out issues with wood burning appliances if you do not want to become WETT certified, just don’t expect the insurers to accept your recommendations for insurance purposes. And when in doubt about a set up refer to a WETT tech.

Be careful!! There’s a lot more than meets the eye in good wood heating appliance inspections.

For example, there’s a particular item I see with the masonry hearth-wood framed wall “thimble” or “pass through” to an exterior masonry chimney. Although I cannot see through or in the wall, I’ve called this unseen item probably more than 10-15 times in my career. The true determination of the fault requires breaking into the masonry hearth and wood wall. I tell people that if they break into the wall and find that it meets code requirements, I will pay for all their costs…I have yet to pay a cent!!!

Who are the people who are suppose to open the wall? The home owner? The WETT tech, or the insurance appraiser? How many remain unopened?

Have seen lots of wood appliances that don’t meet combustible clearances and have also seen lots of so called Wett Inspections of chimneys where the WETT tech came in and okayed the chimney not having swept it.

So its like everything else I suppose, good and the bad and the ugly.

A WETT tech should be called in by the vendor to check the call. If not, I recommend the buyers get an allowance of $800-$1,000 as a “cashback” at closing so they can get the hazard changed to a safe installation by a WETT tech.

If no one opens the wall and there is a fire, then my a$$ is covered…all part of my internal CMA (cover my a$$) policy.

If in doubt I usually state “further investigation by qualified tech, prior to close of title.” That way the vendor is responsible for any noted concerns at their cost and not the purchaser.

For me that the best way to go,I don’t spent much time on wood appliance,insurance will require that a wett cert. do the inspection anyway.


I did the WETT courses and decided not to write the final exam .
To me is was just an added liability I did not want or need .
Regardless they still need to be cleaned so I just pass this on the the person who they get to service the appliance.
We have a couple of home Inspectors ( ex NACHI Members ) who give free WETT inspection with the home inspection.
They also Charge less then we do .
It has not hurt me business so it is obvious they must be desperate for work to do WETT inspections for free.
I am surprised that WETT allows those who never work or install wood appliances to do WETT inspections .
This of course takes work away from those who work on wood burning appliances.

This is the website for WETT for those of you that are interested.


Look into Eco Energy $$$$$$$$$$$$$$$ busy as heck


Thanks Everyone, good food for thought. It is great to have professionals like yourselves that I can bounce these things off. I will give more thought and research before I do anything.

What is that.


Our Feds have implemented an Eco Energy program designed to assits home owners in upgrading old furnaces, DWH, insulation windows etc.

We do an evaluation of the home’s equipment, windows insulation etc and conduct a Blower Door test to determine the air tightness of a home.

We prepare a report to the home owner making suggestions for improvements and upgrades.

The home owner has 18 months to make any upgrades they wish and a second inspection is conducted when they are done.

The feds and pay the home owners a grant based on what they do (up to $5,000) and our province matches the federal grant.

The evaluators are required to take a 24 hour training workshop, do 7 test evaluations then write an exam (on line). Then you get certified to do the evaluations.

Cost to the home owner is approx $300 for first test and $150. for second test. Province subsidizes half of the first test.

Very busy right now, winter comming ya know :slight_smile: :slight_smile:


wow. Neat

Hi Doug,

and you can register and or take these workshops where?


The Feds have license agreements with several service providers, one of which is Amerispec.

I have a working relationship with the local Amerispec owner and I got the training through them.

Obviously I do Eco evaluations under the Amerispec name.

You might want to check out for further info.

Maybe you can connect with a licensee



Has this program been extended? Last I heard it was going to be cancelled. I actually attended an energy audit last year I thought it was a good experience.


The old program, Energuide for houses was cancelled and the new one Ecoenergy replaced it.

Supposed to go till 2011


Thanks Doug!!

In 1997-8 I attended by invitation some of the first meetings the feds had with the provinces on the future energy audit program. (I was certified as a residential energy auditor in the US in 1981 after 7 full days of training; ran an airsealing service using a blower door and a retrofit blown insulation company then) 24 hours of instruction is too little training!!! We butted heads on too many items and I bowed out of the process

The audit program has been running for 5-6 years now and just recently I have finally been seeing audits (have a contract with local gov’t to oversee a residential low income retrofit program) that I would rate as “A” class. Field experience after longer training is what really gets you a good energy auditor. Most of the auditors have never worked in the retrofit field and this is what the program is all about…retrofitting homes.

The program does not test the biggest energy user in most homes- the furnace or boiler. Two years ago, an auditor’s recommendation was to replace the oil-fired boiler ($3500-$4000) without a test…I tested the boiler (I test efficiencies as a regular part of an inspection) and found it to be 81%!! The savings here may be $150 per year for a looooonngg payback. The existing boiler probably had 10 years life left!

Some auditors are doing 4 homes per day…may be possible if they are all similar small boxey bungalows…other than that it’s a money grab because there’s gov’t $$$ available!!
