Tigerloop Oil De-aerator, TN Model, UL Listed

Last year I started having problem with the oil burning stove which is heating the water heating (radiators along the floor boards). It was a huge problem in my area (Southern Illinois), because there are no local technicians, plumbers, HVAC companies, which know the system anymore, because these systems become obsolete. (this is not the case in the NE states where there oil heating is still very much in use). The issue was that for some strange reason (my speculation about it later below) the diesel fuel had air bubbles which caused the igniter (inside the furnace) to shut down the burning process and the fuel pump to stop delivering fuel to the burner. I had several local techs trying to fix the problem, had wasted several hundred dollars without resolution, I called the company which makes the fuel pump (Beckett Co.). The advice was to install the Tigerloop device. I had to convince a local plumber who never heard of this device, (showed him the video from internet,) to give it a try and to install it. It works as advertised. I recommend it strongly. As far as why this issue with air bubbles (or oxygen, or other nitrogen trapped in the fuel) is concerned, I suspect that the diesel fuel has now more foaming additives than in the past.

Decided not to replace the one I had. Started the process of returning it to SH, but it turns out the buyer pays for return shipping. If I had known this, I would not have bought it from Supply House. Guess it's now a expensive spare part.
