I have a 3 zone heating system with one for the central heating and two for underfloor. When I turned the heating back on after the summer the central heating is working normally but the 2 underfloor zones are not firing the boiler and not heating.
I have a tado thermostat for each zone with the underfloors going to a heatmiser UH2.
The UH2 lights up when heating is requested and the boiler seems to wake up but doesn't fire.
I'm unsure where to go with this- does anyone know if it might be the boiler, controls, switches or something to do with piping?
