As a hydronics heating installer in PA I was ask to install 2 wood boilers this year. One was a Hyprotherm regular wood stove which clearly but confusingly said "Coal only" now I understand why. The second one was a gasification unit made by an Amish firm in Lancaster PA. The gasification unit was tied into a large shop radiant floor system and a home with convection heat. The "Coal" unit was tied into a hydrocoil on a ducted system and a indirect water heater. Both of these jobs led me to look deeper into these units. It appears the two best units available are the Heatmaster and the Polar. I use a quadrafire wood stove in my home for wood burning and a condensing lp boiler for the radiant floors. With a wood boiler I will be able to get the freedom of wood burning and still use my radiant floors. The idea of using a Lambda sensor for O2 is interesting as long as it is not troublesome and the unit can still be used if it fails. The use of ferritic 409 ss has proven itself in many condensing boilers and has me definitely leaning towards the Heatmaker. You are fortunate to have an installer that is well versed in hydronics as entering into this wood burning you find yourself many times in the middle of Newtonian physics and the Mother earth news lol Your man is correct about the air to water heat pumps, I was just in Atlanta for the ARH Expo and there are at least 7 manufacturers that have these units. They are monoblocked so they require no charging of refrigerant, you just set them and pipe them in with PEX. Their biggest problem is the max temp of 120 and that is pushing it. Again, an excellent video Tony, you obviously do a lot of research before you purchase equipment. Thanks for taking the time to do these videos.

Nicely done, Tony.. Thanks for taking us on the field trip.. 😁👍

Very informative and filled with valuable information! Thanks for taking the time and effort to get Carl on here and let us view this information. Another good one Tony ! 🪵🔥👍👏🇺🇸 Rick

Thank you for a very informative video on the new models. You both covered so much.

Excellent video, Tony. Great explanations from Carl. I have the G7000 on order and it is supposed to be delivered in the next 10 days. So this video is especially helpful for me. Thanks so much! 👍

Great video Great information 👏 Thanks for sharing Tony 👍

Great information Tony!! Stay Hydrated and Have a Safe Day

I helped son put o In the wood master last month. Both are nice units

Great job you two👍👍. That was the more informative video I've seen to date! Keep up the great work Toney and merry Christmas to you and your family 🎄

Great video. In the planning stages of a new house and shop. I will be putting in a wood boiler to heat both. This video really came in handy. Thanks for the work you put in to your videos.

Very good informative production, good job. Seems very intricate,complex and involved to a novice boiler newbie. I thought you just fill a tank and toss logs. But not the case. Glad I watched.

Excellent video Tony! Lot of good information coming from someone who quite obviously knows wood boilers inside out! Keep up the good work! Len (Devon 🇬🇧)

Wonderful interview Tony😊

I'll definitely be contacting him to talk more about a new boiler! I really like what I see in the new styles available now!! I am use to the old non gasification style like I use to have so it would be a big learner curve for me!! Stay safe my friend

Excellent vid Tony. We never stop learning. BTW, my plumber verified that running the circulation pump during the off season is recommended with the outdoor wood stoves. 😊

Great review!

Great video!

Hi Tony, thank you for this video, really interesting.

👌Good info Tony.

Great video. I more and more convinced that the HeatMaster is the product I will go with when the time comes. Not dealers close by, possible I could be a dealing one day too. I have always been involved in the wood industry whether it's logging, sawing lumber, or processing firewood. God Bless!!

Great video. It would have been great to see their standard two pass models and their multi-fuel models as well.

hi there very interesting . thanks for this one . john

Good morning everyone

nice unit

Nice looking units there Tony. This industry is always innovating. I do have some questions/concerns… 1) How do you clean ash out of bottom of turbulators and back of secondary chamber? With multi passage refractory I see they took a page out of Woodgun boilers. 2) Stainless Steel for nozzle?? It’s hard for me to believe it holds up for a year or 2. 310 SS might last but I’d be skeptical. I looked into making a nozzle out of Inconel but never materialized. 3) 2 separate fresh air intake servos are a much better design. I always tell folks it’s like a cutting torch. Get pressures right at regulator (primary air) then balance the cutting flame with oxy/acety needle valves (secondary air). 3) I would like to see how these boilers would perform if they were charging a storage tank…just like the Europeans do. They are built damn near identical now. Having a boiler burn full tilt burns cleaner and more efficient. Same principle as generators and plane engines. I think US mfgs could meet even lower emission stds by doing this.

This is a fascinating topic to me Tony. I’d love to have one, but the climate where I am in NC doesn’t justify the initial cost at this point. That might change!

Great video Tony. Can you use the Firestarter chips that Outdoors with the Morgan's sell or any other brand that's available to start your fire 🔥?

Please do the video on the hot water heat pump.

Great vid Tony! I would love to install an outdoor wood boiler to heat the garage and house. Do you have any idea on what the ballpark cost on an install of a 4k unit was? Just curious especially with the 26% tax credit. Thanks for sharing 👍🏻👍🏻-TOA

Great video Tony! How many facecords of wood do you use in a heating season with one of these?

Interesting that he shuts his unit down during the day. Is it oversized for what he is heating? I thought most people let them go once you light them for the season to prevent or decrease the thermal cycles which can be bad for stoves (excessive heating and cooling repeatedly). Not saying he is wrong by any means. Doesn't seem to be that cold there yet so maybe it is just a little early to be running it? Thanks for the look. I've always wanted a boiler. Just haven't pulled the trigger yet. I have a wood stove and a pellet stove..

I love innovation but I hate when my shit gets outdated

Would love to have one, just can't justify the cost. The couple hundred dollars I spend to heat a year ( indoor woodstove), the payback would be close to a century.

Fascinating! As a New Jersey resident I do not believe that the outdoor boilers are legal.

I like it…. What is the price for the G10000?

Tony. Do you know what the G 7000 cost. Thanks. Great video.

I would like to know what the G 7000 cost to buy and an install cost

Why don't you show prrices ? Will a load of wood last more than one day ?
