New electric supply - ADMDs in kVA - kVA load required

[Peter1981]

Hi

I'm applying for a new electric supply.
UK Power Networks have requested an accurate breakdown of the "required kVA load".
ALL ELECTRIC 2 BED FLAT.

I have worked out my requirements as below in watts, but am struggling to convert to the "ADMDs in kVA" they require.

Lights: 280w
Sockets: 3200w
Hob/oven: 2500w
Shower: 10000w
Hot water instant boilers (2of) : 20000
Radiators : 14000

Total 61000w

What is the ADMD I require?
And
The kVA load required?

Thanks,
So hot water cylinder/tank is the way to go.

Hot water tank with heating element or unvented hot water tank?

Will the hot water tank supply 2 showers, 2 sinks & 2 basins?

They both have heating elements, but an unvented tank would be my personal preference as you get mains pressure hot water.
You will have to consult the person designing the plumbing installation to find out what size hot water cylinder is needed for the demand.
I think the biggest standard/commonly available size cylinder is 300litres, which I've seen installed for much bigger properties without a problem.
Even if you needed two cylinders in tandem you would still be cutting your power consumption as they are only 3kW each.

Just tell power networks 70KVA, even knowing you are not going to draw that much amperage

You must have money to burn!!!

Why? What is your reasoning?

Have you considered an air source heat pump which would provide room heating and cooling using less power/energy?

See:

Air source heat pumps

Air source heat pumps extract heat from the air to heat your home and hot water. They can extract heat from air temperatures as low as -15°C.

and

Air source heat pumps - Centre for Sustainable Energy

Air source heat pumps are an economical and low-carbon heating option for well-insulated homes. Find out if they are an option for your home.

The only way you are going to get what the energy companies require is to hire a electrical design company to do this for you.
Getting advice on a forum will only go so far especially if they are requesting a break down.

There is a lot of work involved in this.

There are many sparkies who have spent a lot of time and money training to do this.

Utilise there expertise.

Rob I don’t have money to burn but I like to all ways plan for the future

There is planing for the future but have to be practical.

The DNO wouldn't even entertain a 70kva supply for a 2 bed flat. Not when most even 3 - 5 bed houses only get a 23kva supply.

If they did, you would certainly be paying higher tariffs alongside a huge DNO installation bill.

I understand it’s just so different in UK than to US standers
