<p>Hi, I replied on the other thread, but I've just seen this. I think that now you have a 75 degree stat in the load charger, it's less important to worry about the temperature in the load loop / boiler, as long as it isn't too big a volume - because the temp in the thermal store shouldn't drop below the laddomat stat temperature . I'd set the flue stat quite low so that the load loop / boiler doesn't boil. Play around with the flue stat temperatures and see what works. As per my comment in the other thread, if the load loop has been plumbed in properly, it should run on gravity even without the pump running, and so shouldn't boil. Best wishes, Geoff</p>
