Indirect mains connected cylinder

[Leadman]

[FONT=Baskerville Old Face, serif]Hi,
Not sure I have the right section for this but ..
I need to replace a standard indirect cylinder and header tanks with a Heatrae Indirect Megaflo unvented cylinder or similar.

At present the system works fine and there is no overheating of the system, but in order to get rid of the header tanks and increase flow to the hot taps (which is the object of the exercise) I need a mainsflow type cylinder.
The problem is the only viable heat source, which is an AGA.
I am told that the direct mainsflow systems are inefficient when used with an Aga and therefore would like to fit the indirect type.
Has anyone out there done this before and if so, did you just connect the flow /return from the Aga as with the standard cylinder or was some sort of in-line diverter valve needed to avert the possibility of the cylinder water boiling.

Thanks [/FONT]

What sort of aga is it? Gas/Oil/Solid Fuel?

Have a look at heating innovations h2 panel for unvented cylinder connection.

Just been to see about a replacement tank connected to an aga, its an indirect vented tank. I'm looking to replace it like for like as last tank has been in for over 30 years. All be it better copper back then. Aga that's fitted is oil in this case. NOt sure this helps but bit more info for you

sshould say that there is no valve's, stat's, pump's or diverter's in line to tank. it just boils! don't think this would be a preferred method now adays
