If anyone can add their two pence worth of thoughts I’d begrateful.
I have a wood burning stove with a back boiler in Francewhich is going to be used for heating only and which I’ve yet to plumb in. Myoriginal simple design was using 22mm pipe on the primary flow and return. Onthe flow side I was going to connect two motorised valves, one normally openthe other normally closed. On the return side was going to be the heating pump.The circuit has six rads five of which would have thermostatic valve the sixthwould be the heat leak. However an English heating engineer said whereas itwould work it would not be as efficient as it could be and drew out a schematicdiagram for me. The flow and return pipes to be 28mm from the fire to the firstfloor from here it would tee off to a heat leak rad; carrying on a littlefurther in 28mm the flow and return would connect to a neutralizer! From the neutralizerthere is a secondary flow and return in 22mm pipe going to the rest of the radswith a heating pump placed in the flow.
Now I’ve looked up neutralizers on the web and they all seemto be for connecting up two heating systems but I don’t want to dismiss thisguys design as apparently he is top notch at his job. Incidentally I’vedeliberately left out things like header tanks, drain off points andthermostats!
Question is, is this really better than my design as I don’twant to go to the expense of a neutralizer if it’s not required?
