House Load in Kw

[Steel Kneel]

Looking at a self build and I've approached the local DNO. They've asked what my Kw load is likely to be.

It's a 2 floor 4 bed detached with a gas central heating system.

I'm looking to run a rainwater harvesting pump.

Various lighting about the property, shed, garage and some powerful security lights.

I'd also like the option of install solar panels & powerwall in the future.

What am I best advising my Kw load could potentially be?

18Kva
should give to 80 to 100A supply depending on what they have available.
standard domestic supply.

That will raise some eyebrows with the DNO, that's heck of a lot more than they normally allow for a domestic supply.

Ask the person who is designing the electrical installation to provide you with the after diversity demand.

You need to sit down and do a proper load calculation,
then apply diversity that gives you a fair approximation.
but 80A is usually considered adaquate for most domestic situations.
You can even push it out to 100A If needed,
But 100A is the maximum for standard service drop.
Beyond that requires bigger lines or multi phase.
But I doubt that you will need that.

Should this read 18Kw? The DNO are specifically asking for KW's!

What should this be in Kw's?

kVA and Kw are very similar, for this purpose you can consider them to be interchangeable. 80A is just over 18kW.

 

[multimick]

i always put down 20 kva , never had a problem

 

[dmxtothemax]

I think a typical 80A service will be plenty.
it would be rare to excede 50% of even that.
But if you have motors it will be handy.

All those things you've mentioned are relatively low loads... assuming you'll be using LED lighting of course.

You need to consider the high loads... like electric heating ? electric showers ? ''plant" cultivation ? etc.

16kva is standard on these forms.
