Hello all,
Having recently moved house, we've just changed our old unreliable boiler and vented hot water tank system for a Viessman 100 combi boiler.
We have radiators upstairs and a few downstairs - all now getting much better heat through them. We also have two wet underfloor 'zones' downstairs. The three circuits are separate and controlled by new Tado thermostats.
The underfloor system has two switches:
1. Drayton zone valve actuator - set at position A
2. Wilo pump - the plumber has set it at the 'fixed' (rather than variable flow, which the manual seems to suggest is for underfloor systems) at max speed 6.
Plus, it also has a radiator style thermostat knob on the pipe to control the heat?
These were both here before the heating system change, but I'm sure were in a different position. So far, the smart meter seems to suggest that our underfloor heating is quite expensive, despite being on low and not very often!
Any tips and suggestions very welcome! Have been in poorly heated houses for a long time, so would be good to get to grips with the system!!
