Hi all.
I have done several adaptions to my boiler including supplementing the central
heating with a hot pre feed so my boiler runs 100% on the external source via
a plate heat exchanger. This has worked extremely well over the winter, and
the same heat source will be heating the pool ( when I set it up sometime soon
). I have been toying with the idea of linking onto this loop for a second
time, that's already in place, using another plate heat exchanger to run the
hot water for the house. The loop can run at anywhere from 62 degrees up to
around 90 degrees c depending on my choice and I was thinking that if I can
link into my cold feed in ( the same as I have linked into the CH loop to put
hot water pre boiler ) I should be able to stop the boiler firing up and
therefore use no gas.
I have read what feels like hundreds of articles but I cannot find whether or
not I can do this on my old boiler.
Has anyone tried this before or can I simply not feed hot water into the
boiler?

Hope someone can help.
Thanks
David
