Wood burning stove/boiler and thermal store at same level?

[iank]

We wanted to put in a wood burning stove with back boiler linked to a thermal store (also linked in to an oil boiler and thermal panels) that are on the same level in the house. One company seemed quite happy with this (or at least did not mention any problems), while another company said they had done this once and never again, as there were continual problems. I did not know enough then to ask what were the problems, but I understand it can be thermo-syphoning back from the tank through the stove when not in use.
It is suggested this can be overcome by siting the thermal store on a plinth as high as possible, and using antisyphon valves and a Laddomat or similar.
Would this be OK?

It is not possible for it to thermo-syphon back throught the stove when its not in use with a thermal store. Its a neutral point and any number of different heat sources can be added. You do not need a loading valve (laddomat) on a stove.

Thank you.
Forgive me if I am wrong, but I thought that the main function of the Laddomat or similar was to ensure that the stove was not cooled too much by a load of cold water from the tank, as this encouraged soot formation if the wood burned at a low temperature.

Almost right,but not quite!! It's to keep the firebox at optimum temperature,this explains it quite well.

Heat charger - stove Laddomat 21 heat chargers - backboiler heat charger

A stove working on gravity to thermal store is fine, a wood boiler or biomass linked to an accumulator tank needs a loading valve to keep the return temp high.

Wood boilers and stoves should be operated at a high temp to stop the formation of tar.

Just noticed you want to put them at the same level? It can't be done.
