Simple Q Please

[bobpants75]

Just double checking please - I have bought a pool heat pump and my electrics are good old live, neutral & earth.

On the attached diagram, I should be connecting live to 'L ' & to '1' in parallel & also neutral to 'N' & '2' (& obviously earth to earth)

There is nothign more I need to know is there please?

Thanks in advance
Bob

What electrical load will the unit use- a quick google suggests items come in various sizes from 6kw-35kw

Where is the power coming from ?

How far from the main fuse board is the cable run and what size / type of cable provides the feed ? Is it surface or ducted ?

There's rules regarding swimming pool electrics / Part P and BS7671:2008 do you intend to DIY (dangerous and potentially fatal) or intend to get a pro in to do the work to regs and cert the job ?

What sized pool do you have and where will the pump be located ?

Looking at your diagram, the connections for live, neutral and earth are straightforward. It does say that pins 1 and 2 are the output for a pump. I wouldn't think that you should connect the live and neutral in parallel to this. I'd have thought that this was to supply another pump somewhere.

All you need to know is that you must get an electrician.

The diagram does not tell you to connect the supply as you have stated, and if you are so incompetent that you think it does then there is no way you should be doing the work.

That's the heating output. The maximum electrical load is about 1/5 of that - eg the THP12 has a heating output of 12kW and max power draw of 2.4kW.

the THP12 has a heating output of 12kW and max power draw of 2.4kW.

How does that work? Where does the other 9.6kW materialise from?

From thin air.



Literally - it's an air-source heat pump.

Literally - it's an air-source heat pump.

...or thick earth, if its a ground source unit.

Which those Toshiba models are not...

 

[magicmushroom666]

Sounds like you need an external pump, maybe the unit only does the heating, not pumping as well?

I really wouldn't connect L & N to pins 1 & 2 on the connector!

 

[ban-all-sheds]

Sounds like you need an external pump,

Of course you do.

maybe the unit only does the heating, not pumping as well?

Of course it doesn't - it's a heater.

One assumes that bobpants already has the pool pump....

Thanks all for the replies - I did consult an electrican to be sure and joinerjohn you are pretty much spot on !

I do think phrases like 'if you are so incompetant' are not exactly helpful though for anyone

 

[ban-all-sheds]

You are unable to understand a simple wiring diagram.

It's hard to see how that makes you competent to do the work.

I did consult an electrican to be sure and joinerjohn you are pretty much spot on !

So even after joinerjohn spelled out what the diagram had already told you, you still didn't get it.

But you do still think you are competent.

Oh well.

B.A.S. is correct but I dont understand why you have to be so rude about it?

 

[ban-all-sheds]

"The diagram does not tell you to connect the supply as you have stated, and if you are so incompetent that you think it does then there is no way you should be doing the work" is a pure statement of fact in a neutral tone.

It contains not one word of abuse or insult.
