    I did, but putting on my work hat i couldn't advise you to do it because from a gas boiler point of view, if the limit stat triggers or if the boiler has a pump over run to help dissipate heat, then it can't stop the increase in heat as the gas boiler controls can have no impact on the heat generated by the back boiler, put simply your gas boiler could be saying no, no, no and your back boiler could be saying yes, yes, yes. in respect of dumping heat down the return, if the system temperature is up to temperature then you may not be able to dissipate the heat under extreme conditions so if you could find a way of fitting a temperature/pressure relief valve on the return then this will open at 98c and release the system water and allow cooling water from the f+e tank, i have never seen one used in this manor as they are used for unvented cylinders(there maybe a heating version), but i can't see why it wouldn't work, fitting it would be the hard thing, if you have a look at diynot.com and ask the same question you will get a more definitive answer as there's a load of gas heating installers who post on that site, and as i said it's all about safety, safety, safety, Gary.

    Nice one Gary, Taking on board your advice, I think I will run the two heat sources separate. I'll bypass the gas boiler for when the fire in on and vise versa.

    All done, works a treat, looking foward to low gas bills!.
    As the lads on the thread said you need a vented open system not a closed one which is more popular in most homes! So check that out first. You must be able to get cold water to flow thru if the was a power cut and no valves on the pipe to the attic to restrict flow.

    hope this helps
