This diagram illustrates how simple the heating system connected to a combi boiler is. Heat flow rate. This is a combination of the two diagrams above. Anybody got any ideas or a circuit diagram how to connect the system.

An automatic bypass valve is fitted inside most combi boilers by the manufacturer these days. Systems using combination boilers will also need zone valves if separate systems of heating require different times and temperatures. I ve just had a completely new heating system put into my house we have two zones one for sleeping areas and one for the rest of the house.
