Any indirect cylinder you like 😀

Generally a 1200mm x 450mm but it should be sized to suit your requirements which are ??

Don't expect your woodburner to behave like a gas or oil boiler. The heat outputs from solid fuel boilers have always been "slightly" exagerated and that you can heat ?? many radiators. The figures they quote are based on ideal operating conditions ie full fired, with best available fuel.
Solid fuel does not operate like that in real life. Different fuels are burnt with vastly different heat outputs. The heat rises and falls depending on how the boiler/stove is fired. Most times the rads have a far lower temperature/output than gas. This is not a problem on new build as they are well insulated. You will have lots of hot water though.

As long as it is open vented under no circumstances use an unvented cylinder with an uncontrolled heat source

have been told cylinder should be dual coil and can be fitted without header tank in loft, i guess this means it would have to be mains pressured .
does that make any sense???

Just had a look at Aarows range and they do look very much like a villager, I certainly would not contemplate installing it on to an unvented cylinder, I would contact the Aarrow Directly and ask their thoughts

I should have been clearer in my earlier answer.
Any open vented indirect cylinder you like.

"have been told cylinder should be dual coil and can be fitted without header tank in loft"

Only reason to fit a dual coil is if you are planning to add an additional heat source.
Do not fit an unvented cylinder.

There are a few different options but you should perhaps get some help from a Hetas qualified installer.
Fitted incorrectly, it can be as dangerous as a gas explosion.

You can fit a "thermal store" and have the benifit of mains pressure hot water. Look here [DLMURL="http://www.newarkcoppercylinder.co.uk/cylinders/thermal_store/"]Thermal Store Copper Cylinders | Newark Copper Cylinders[/DLMURL] I have used these and are a good company and will make to suit your requirments.
