This is an add-on system to my existing wood stove. It works great! I really like the electronic controller and dual mode it offers. Installed with four 5” vents – really high quality vents and overall the system.

It took me just two days (my weekend) to install all the vents on my 1800 sq ft ranch home. My existing wood stove with a built-around heat chamber and air turbine made a big difference. Noticeably saved gas bills in off-season months and improved home comfort overall. I purchased the HDS system with a set of polished chrome 4” vents which look great and they are nicely matching 4” chrome recessed ceiling lights. Very Happy with it.

I got a smaller version AT400 turbine. My 1000sq feet cabin had only electric baseboard heaters, so I decided to try this system and installed with it a small wood burning stove. Amazing results! Not only is it evenly warm in all the rooms but saves tons of money on electric bills.
