Our old Landis & Gyr programmer is audibly creaking and, as I'm ordering from Screwfix, I might as well replace it.
They have a Horstmann C27 (code 11225) at £26.49 and a Danfoss FP715 (63760) at £35.99.
Anyone got any views on which might be better? It would be used in conjunction with a motorised valve on the DHW and an Eberle programmable room thermostat which were installed some time ago.
TIA
