Hi guys hope you all well I have been asked to fit a system boiler on an oldish system but am thinking of having it as a spit system using a plate heat exchanger to have the boiler side pressureised and keep the system side tank feed,as oldish pipes under floors.i want to use an atag but there heat only only goes to 18kw and the house is 21kw +hot water.
I have never done a system this way but just wanted your thoughts
Thanks
