    Need a room thermostat?

    My Saunier Duval Thema F23E boiler manual says it can be run without the need for a room thermostat. I have TRV's on all rads. Is there any advantage to adding a room thermostat? Any real problems if I leave it as it is?

    heat recovery unit

    I need to install a ventilation unit like a ventaxia heat recovery unit in a basement conversion. Any suggestions for the easiest unit to retro fit and wire up/ vent to the outside. Was initially recommended the Ventaxia HR100RS but his seems to small for a 5m x 4m x 2.1m room?
