Oil Heating Problems with Gas/Air in Oil
When oil is drawn up from the oil tank to the burner large amounts of gas bubbles can be released from the oil. These gas bubbles are released when there is a negative pressure (vacuum) in the suction line. This occurs in almost every installation, but above all when oil must be lifted to a higher level, drawn through long suction lines or when the suction line is too coarse for the needed oil flow. Air can also enter the suction line if all connections are not 100% tight or if the tank is run empty. The gas/air bubbles flow with the oil into the oil pump and are the leading cause of breakdowns, increased build up of soot, unnecessary wear and tear on the oil pump and higher oil consumption.
...With One-Pipe System Without Tigerloop
The one-pipe system without a Tigerloop is not to be recommended. This is due to the increased risk of breakdowns as gas/air bubbles cannot be removed from the oil pump during operation. Such a system will only work as long as the oil is continuously 100% free of gas/air bubbles. Moreover, it is impossible to automatically de-aerate the system during start up or after running the tank empty since a tool is necessary.
Tigerloop makes a one-pipe system possible for all types of oil heating installations helping to ensure environmental safety, cost effectiveness and reliability.
In an oil heating system using a Tigerloop, all oil passes through the automatic oil deaerator, which effectively removes all gas/air bubbles from the system. This eliminates oil pump and nozzle problems associated with gas/air in the oil.
Own Two-Pipe Circulation
An oil pump delivers the same amount of oil irrespective of what is actually needed for combustion. In the case of a normal domestic burner, only 5 % of the delivered oil is actually burned in combustion. The remaining 95% is transported by a two-pipe system back to the oil tank. With a Tigerloop automatic oil deaerator no oil needs to be transported back to the tank. The oil that is not burned in combustion is lead back to the Tigerloop where it is deaerated again and again automatically. For this reason only the amount of oil to be burned in combustion is sucked from the oil tank.
