Default So how much power does an oil filled radiator actually use.

Not that substanbdard it's our standard. Only those that are non standard get 240V.

Strange that, just checked my power monitor and it's 239V


Yep that is correct for domestic supply.
Which doesn't apply here.


So why whine that you weren't getting the full 2kW from the heaters?


I'm NOT.
I know you're having difficulties in reading and maths but READ the subject line.

"So how much power does an oil filled radiator actually use."

We had to come in line with teh EU so that meant 230V, then managment needed promoting so they decide that they;d put in a system to save power and therefore money by installing an auto-transfomer which took us down to just below 220V.

Yup, substandard, especially under any decent load.


Standard for us and within the tolerance expected.


When you say 'just below 220V' you actually mean 202 (that you told
us)?


No you clueless ****er, that was thew LOWEST I've EVER seen it at AND that was when pulling 40 amps from a 32 amp MCB !
I don;t think I"ve EVER measured the lab volage at 240V it's always been around 220V but we have little reason to measure it as the vast majority of labs use low voltage DC and no one gives a **** what the AC voltage is.
We have a lab tomorrow where the students design a DC PSU.

We can't give them the mains to play with so we give them a 12 V AC PSU.
I;ve had to contact rapid as we need a couple of spares and the ones we brought some 4 years ago have been discontinued.

So come on genius tell us what the AC volage should be from one of these.

If connected in our lab at 215V and yuo can then guess what it might give at your home on 239V



Which is why I 'set' it to 2KW and not 700W or 1300W .


Yes, I know and I was saying you might also try setting it to Heat
level II and see what happens.


I did ~1050W so where do you get 1300W from,

Oh yes you've forgotten apparently you believe our standard mains voltage is 202V
So you think a 2KW heater on 202V rather than 240V will still consume 2KW irrecspective of the input voltage.
How comes it didn't occur to you that a 2KW rated heater will give out less than 2KW if placed on a 202V supply, this is why I asked you what;d you''d expect if we ran if from a 9V battery would you STILL expect 2KW ?

Anyone with any insight would have known that 202/240 should give you the fraction that you use to multiply by so :-
A heater of 2KW at 240V will consume 2000W
A heater of 2KW at 202V will consume 1683W

So if it's consuming 700W already we have 1683-700= 983W NOT 1300W that you expected.





eg, If you get 2000W for 2 hours and then it drops to 700W for 2 hours
then the average will be 700W and 2000W for that 4 hour period. IF
putting it on heat level II(1300W) meant it didn't trip the overtemp
stat you might get 1300W continuously for the entire 4 hours.


I think that is unlikely.


But as yet untested eh?


Yep, I wouldn't expect anyone to set the heater to a mid setting to get the maxium heat from it.

Why buy a 2KW heater just to run it at 1300W ?
Can you answer that at least.


We don't want hot radiators we want the room to be hot preferably, that is what efficincy is about.

Bwhahahaha ... you really don't have an effing clue do you? Are you
anywhere near a science teacher to ask them to teach you all about
basic thermodynamics?



Still talking **** I see.


What, that a room temperature heater will heat a room better / quicker
than a hot one (you can't make this stuff up!).


what's a room temperature heater ?


HTF do you think a heater heats a room?


Depends where it's placed.



Do yuo actually know what these things are used for ?

Yes, that's why I'm trying to teach you.

yuor the one that was suggesting I send working heaters back because you didn't know how they worked.

Liar.


So why did yuo think they were faulty. ?


Why do you keep lying?


why did you contact sales ?
and what was sales reply.
Go look it up in your email in box






Why did you contact salesd aledgly to help me and get a wrong result ?


Why are you so ungrateful when people try to help you?


I'm grateful if they are actually helping, but you passed that point a long time ago.

John rumm was helping you are NOT.
