Contactor or this PIR

[uksparks]

Hi,

Got a job to do next week, just wanted your opinion on it really,

I am fitting a Dimplex IRX2000 Infrared Heater 2kW, and it needs to come on automatically when someone enters the room, only a small outside toilet.

Anyway, I was going to put it on a PIR with a contactor, but then just looking at the PIR it says "Switching capacity: 2000W incandescent and 500W fluorescent."

What do you think? A contactor would be the better option I would have thought.

I was going to use this: LAP Indoor Ceiling Flush PIR | Light Sensors | NoLinkingToThis

 

[SPARTYKUS]

Yes, I would use a contactor. Or a higher rated PIR.

Yep. Contactor. Mind you I cant see the point as surely the room will still be cold by the time anyone is finishes their business.


Ooops. Just re-read. Infrared heater......

Where's the naughty step?

 

[Octopus]

Recommend a fan heater??

 

[Silly Sausage]

2k incandescent, i.e. resistive.
Assuming the heater is purely resistive, just use the PIR alone.

If the pir is rated to switch 2KW then it is rated to switch your chosen heater. You will find that the contacts in the pir relay will not last as long when switching their full load rating as they would if only switching the load of a contactor coil.

I think for what it's worth I'll go down the contactor option as I know it's the better option.

there have been a few ideas floating round in my head for heating, one was not at all, the other was a small storage heater who h would work ok and the others were IR or a down flow heater.

i did stress to them that by the to eh you have had a pee it will still be cold so a storage heater would possibly be more suited, but they didnt want it, so have gone down the IR route.

this sodding toilet is a pain in the bum, I had to hang a sodding chandelier in there last week, apparently snobby people who have their nails done etc like to have a nice toilet.

check the wall paper out, this was £150 per roll I think they said!

Are they nouveau riche?
Those people usually have as much class as the solids one flushes down the water closet.

 

[davesparks]

Are those glass trough things closed at the too or open so that air can flow up through them?

 

[uksparks]

They are Dar lighting Academy 5 light pendants, RRP is £300 each.

they are open at the top yes

 

[davesparks]

I couldn't care less how much money was wasted on upside down feeding troughs.

I was just curious as to whether they were going to burn out the lamp holders and internal wiring in a matter of weeks or not.

 

[uksparks]

They have 5x 60w filament lamps in them, I would imagine they will be ok.

 

[davesparks]

They'd be buggered if the top was closed, the heat from the lamps would knacker them very quickly. It's the same as those glass teardrop shaped lampshades you can get or fire rated downlights with dichroic lamps in.

The combined heat output from 5x 60W lamps is quite considerable!

 

[Silly Sausage]

They have 5x 60w filament lamps in them.

I thought they'd been outlawed now.

Do you need to wear shades going in that room?

Nope, they can still make and sell 'rough service' lamps because they were excluded from the ban because they are not 'general use' lamps.

They can pee in this room then!

 

[uksparks]

lol yeah very true. They have three of these 5 light units in that room, so 900w of heating!

 

[uksparks]

They can pee in this room then!

Someone probably has, it's 400 years old!

They write "industrial use" on the box for the rough service lamps to get around the ban!
