My brother has a three storey house and all storey have one manifold with pump for underfloor heating, and one Nest thermostat 3rd generation in each floor . G-F-Loft Each floor has its own motorised zone valve , with gas boiler the setup is working perfectly as wiring centre is in place and the classic switch line from wiring centre is firing the boiler when is calling for heating . he wants to switch to Samsung 12kW Air Source Heat Pump & 170L Cylinder can he keep same wiring centre and connect the boiler switch line to the Samsung heat pump so he doesn’t interfere much with the current set up . thank you in advance for your advice . erment
