@alfapat I think modern TRVs can be fitted on either side. The lock shield will restrict flow whichever side it is sited
@alfapat Remember Pat, as the outside temperature varies, so does your flow temperature. If you are not getting to room temperature today when its war...
@alfapat yes if you can get the maximum flow temp to 46C from 50C that will be a result. you will find that each adjustment will affect every other...
@alfapat that is what water law is for Pat. It automatically adjusts the flow temperature to take into account the OAT. Once you have the rad valves r...
@chandykris just give them a good wash out before fitting them back 😁
@wawyed Thats the only thing I could think of that might account for the difference. It looks odd but I doubt its affecting COP much
@chandykris Yes, I did that, just bought two big radiators and shifted the others into different rooms. No problems.
@wawyed Mine isnt doing that, is your water pump PWM controlled?
@johnnyb Is that different to what Toodles has shown in the response above?
@toodles Thanks, thats actually more than I expected so quite useful.
@alfapat So this is the lockshield valve Sometimes they have knurled knobs on which can be used to adjust them, but if not then just use a smal...
@alfapat Sorry, I didnt see the temperature readings. So you are losing about 4C by using the buffer which I think is about an 8% loss in efficiency. ...
