Where should a SpiroTop automatic air vent be mounted?

SpiroTop automatic air vents should be mounted at any point in an installation where air can gather and in places where air pockets are present. The SpiroTop should be installed vertically, with the connection at the bottom. Note: an automatic air vent only removes free-circulating air. To deaerate an installation actively and also remove micro-bubbles and dissolved air, a deaerator or vacuum degasser should also be installed, depending on the type of installation.

Where should a SpiroVent deaerator be mounted?

SpiroVent deaerators should preferably be installed at the hottest point of the installation. In a heating system this is directly behind the boiler. In a cooling system the air separator should be installed in the main return pipe.  Installation in front of the pump prevents accumulation of micro-bubbles around the pump shaft. Air around the pump shaft can significantly reduce the lift of a pump.

Where should a SpiroTrap dirt separator be mounted?

As dirt particles are always present in the main flow and are difficult to divert to a bypass pipe, a SpiroTrap dirt separator must always be mounted in the main pipe. For both heating and cooling systems the main return pipe is the best position.

Can a SpiroTrap dirt separator become blocked?

Under normal circumstances a SpiroTrap dirt separator cannot become blocked, as all the dirt is removed from the stream and collected. As a result the collected dirt will not cause an increased pressure drop or flow resistance.

How much maintenance does a Spirotech product need?

A SpiroTop automatic air vent or a SpiroVent does not require any maintenance. After initial draining upon delivery of an installation, a SpiroTrap dirt separator only requires opening for a few seconds every now and then. This is normally done during regular maintenance on the installation.

Where can I buy Spirotech products?

Spirotech products are available via all the regular wholesalers. For specific supply questions or project information, please do not hesitate to contact us.

Do you hear a ticking noise in your heating system?

Bubbling, ticking and other noises are usually caused by excess air in heating systems. These noises aren’t just annoying – they indicate your system may be using too much energy or is suffering from contamination or corrosion.

Do your radiators heat up unevenly, with warm and cold spots? Or do some radiators not heat up at all?

That’s a nuisance because rooms aren’t being warmed up efficiently. It also means your boiler is probably using excessive energy to reach required room temperatures.

Is your heating system water turbid, or even black?

This is <b>caused by very tiny magnetic particles</b>, or magnetite. Magnetite will settle wherever there is a magnetic field (for example valves, heat exchangers, pipes, radiators, pumps and calorimeters). <br><br>Magnetite leads to reduced installation performance, higher energy costs, breakdowns and excessive wear and tear.

Are your heating costs rising disproportionately, even though you’re not heating a larger area than before?

The presence of air and dirt in the system water could be preventing efficient heat transfer, which results in higher energy bills. Maintenance and repair costs might increase, too, as a result of excessive wear and tear.
