Hello,
my name is Markus, and earlier this year my family and I fulfilled our dream of owning a house. In spring, the electrical installation suddenly failed us, and due to the storage heaters, it got a bit chilly at first. Now we are almost finished with the electrical work, and a few days ago the pellet boiler was delivered. A friend was originally going to help me with the installation, but he is now unable to assist due to an accident.
Soldering the pipes seems like the least of my worries since I have almost completely replaced the water pipes as well. The pipe layout plan is already prepared, but we forgot to include the expansion vessel (MAG). I have now roughly pre-installed everything between the buffer tank and the boiler. The expansion vessel is an 80-liter (21-gallon) unit and should be installed on the return line before the return flow riser.
Here are my questions: Does it matter if the expansion vessel is connected with an 18mm (3/4 inch) copper pipe, including two sections of 1.5 meters (5 feet) length and a 90° elbow, or is that setup acceptable?
Currently, the connection on the expansion vessel is at the bottom, and I also have a shut-off valve. However, when I bleed the system, there is still some air trapped in front of the membrane. Does this air cause any problems, or does the connection need to be from the side to ensure it is free of air?

Hello
Only the actual issue with the air, when the connection is at the bottom and the resulting improper venting, has unfortunately not yet been addressed.There are many pressure relief valves (PRVs) that have the connection on the side or at the bottom. Venting is not possible in these cases and is also not necessary. The air pocket that remains does not affect proper function.
