boost boiler??

[CXR100]

anyone heard of one on a solid fuel stove? need to go and see a job to pipe it up , what's the best way to get it to work a cylinder , 1 or 2 downstairs radiators ( have to be pumped) and 1 heat leak somewhere upstairs , ive got limited space in loft, so going to be a coffin cwsc I think , the cylinder is upstairs , does it matter if I put the expansion tank above this? thanks

It does matter if your using the coil in the cylinder , is this stove the only heat source, yeh u need a heat leak rad and its best to use a fibre glass FnE tank with a copper ball ( float ),
The system must be able to work via gravity ( HW ) incase of power cuts,
Might be worth having a deek at some of hetas web sites ,

yes im using the coil in the cylinder, so what I was wondering is does the hw always have to work via gravity? and heating then in 22mm pumped?

If you are keeping it simple, then yes, 28mm Gravity so that it circulates well without relying on a pump. Heat leak for if a pump or electric fails.
22mm pumped pipes to rads worked by a pipe stat onto the 28mm primary return IMMEDIATELY where it leaves the cylinder.
Probably need to use a 28 mm injector tee at boiler. Stove MIs will say this.

It can be wired with high and low limit stats on the coil so that when the coil reaches a certain temperature the pump will kick in and move the water round the rads , have a look at this diagram,
