Numbers.

What does those numbers 0-5 on valves mean? Is there a standard temperature settings for it? — Preceding unsigned comment added by 94.1.209.147 (talk) 14:25, 24 February 2012 (UTC)[reply]

CO2?

I really don't think it is appropriate to talk in terms of CO2 for this subject. Radiator values are not CO2 valves, they are water valves. Heat sources vary widely and frequently release no CO2 at all, such as geothermal or nuclear-electric, or biofuels (like wood) that release recently absorbed CO2 that otherwise would have been released by decomposition. The primary source of fuel saving (which is what CO2 estimates a roundabout measure of) is simply burning less fuel by providing less the the boiler, either by a lower thermostat setting or fuel supply.

The purpose of these type of values is to optimise comfortable room temperature, not "save" CO2. Simple sitting in a room and breathing out will release far more CO2 than anything done to a radiator valve. Palfreman (talk) 13:50, 14 September 2018 (UTC)[reply]

Historically, the use of individual TRVs, and their advertising, is based on saving fuel costs during the energy crises of the 1970s. That equates more directly to CO₂ than it does to comfortable temperature. Andy Dingley (talk) 14:25, 14 September 2018 (UTC)[reply]
