  1. Doug Niederkorn, Service Manager PCS

    Our company has purchased 3 of these heaters. They heat fast, set up quick and are very user friendly. The best part of our investment however is the support given by Dave. ALWAYS just a quick call away, and has the know how to get you on right track.

  2. Doug

    Our company has purchased three of these. THEY ARE THE BEST HANDS DOWN! We have other units, but our triplets are our go to heaters! The better part is Dave is always a call away if you have ANY QUESTIONS! By far beyond superior product and service!

  3. Doug Niederkorn

    Now have four of these, work flawlessly, one man setup, low propane useage, very economical
    To run. Looking to add more units to our operation.
    Best bang for buck, and hands down best customer service.

  4. Matt Davidson

    This is a GAME CHANGER! Buy as many of these as you can afford. Easy to set up… easy to use.. this thing is a monster. 175,000 BTUs at this price… you’ll be so glad you ordered this heater. This is a must have. We have been able to treat places the competition couldn’t get to and have been able to win over property managers just because we could go where others cannot. This thing is so versatile!

  5. Doug

    Now five of these and looking at more, We have other brands of heaters, but those sit in shop. The Deltas are our work horses that operate flawlessly each and every time! The price is great , but the customer service is by far the best in the industry. Dave truly knows his equipment in and out. They are super easy to use, and easiest to set up. The new thermostats are great. We updated all ours to that design. Our company won’t go to any other heaters or supplier.

  6. Kenneth Barychko

    David and his team are excellent. Love this unit. We originally had the flagro 400 which is an awesome unit in itself. We added the delta 175 to our company for smaller jobs. His customer service is above all. He will answer and help you with any question you have. I can not say enough about David and his Team

  7. Danny Belisle

    So far so good, this machine is great for smaller jobs and it is a workhorse for its size. even better if you put it inside and then you are able to treat up to about 1.400 SF instead of just 900 SF. Looking at buying my second machine here soon. Dave has been great and has always been there for us this far.

  8. Jen

    Our company purchased one of these machines and it works great!!! The training video and customer service was a huge help!

  9. Dead Bug Walkin’ LLC

    Beast of a lil heater. Best of all it can be used inside of a home. Directions will explain the process of using it indoors, but using a fan blowing into the duct when used indoors will insure better air quality in said area being heated plus cools the heater itself while being inside the remediation. Our company has many heaters that we’ve bought from this company. The owner runs a tight company that gets you the equipment you ordered asap which is great when bed bugs are what you do for a living. You can see a picture of this heater being used to treat one single bedroom in a home at our website here:

  10. Duke NukemKS

    Excellent first heater. Simple, intuitive, easy to use – even for a newbie. No need to worry about amperage, as with electric heaters. Note that Heater shuts down if air quality is poor (when heater is left in area being treated.)

    This company’s staff are the best I’ve ever dealt with – professional, polite, accommodating, and interested in seeing customers get exactly what is needed, and only what is needed.

    But with confidence!

  11. Cody

    Ive purchased 4 of these machines. They work great! They’re very user friendly and easy to set up. They get it done!

  12. Chris (verified owner)

    Wanted something powerful enough to handle the SF we need to cover most of our rental units. This think packs a punch and is simple to use! Wi-Fi monitoring is great! Because of its cost effectiveness, we use this for preventive measures as well now. Tenant moves out and we heat treat the room along with our carpet cleaning.

  13. Justin Nowotny

    Dave and the team at Thermalflow Tech are fantastic. We have 5 of these units and they work like a champ. Very user friendly and work great on bringing your structure up to temp. No flaws in the equipment whatsover and haven’t had any issues. Also, the customer service is second to none.
