Talk:Thermostatic radiator valve

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)

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)
 * 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)


 * But that's not actually the same as it being related to CO2, is it? It's a marketing angle that captures the current popular imagination, not a fact. I'm sure it wasn't mentioned during the 1970s energy crisis either, merely the possibility of energy saving due to the high price of fuel re disputes with coal miners and oil suppliers in the Arabic world.

Where not to install a TRV
The claim "TRVs should not be installed in bathrooms [because] the heat emanating from the bath/shower will cause the TRV to restrict water movement; which worsens condensation levels in bathroom" is false and misleading: if one wants to increase the bathroom temperature to reduce condensation he can simply adjust the TRV setting. Indeed, Danfoss and the cantonal energy and environment services of French-speaking Switzerland, which are clearly much reliable sources than driss.co.uk, recommend the proper setting of the TRV in bathrooms, implying that TRVs can be installed in bathrooms. —Esponenziale (talk) 10:46, 15 March 2020 (UTC)

Snowflake setting
I think the temperature settings table should probably have a snowflake character (❄) instead of an asterisk (*), since that is what the symbols is. TomFryers (talk) 11:51, 16 February 2021 (UTC)
