Can 2 cylinders be manifolded together

[steveafoss]

Hi can anybody let me know if its possible to manifold two cylinders (vented) together at the moment the customer has one indirect cylinder but they require more hot water and was requiring to have another direct cylinder added. Also the second cylinder would be 12" lower. Secondly the vent, it would not be possible to run this completely horizontal to above feed tank due to roof shape. The heating is run by an oil fed aga
( they need more hot water to fill double bath just been fitted )

PS I have suggested a larger cylinder but the one fitted was new 2 years ago (not by me) and they are not keen to replace this.

id put another indirect in as one coil may struggle to heat both in a reasonable time and as second one is lower you might tend to get it colder than the other if just as a slave
