builders and there good ideas

[lockhes]

Hi

Evening all been to look at a job about installing 2 instant water heaters in this property, no problems you would think.

These heaters are zip dex12 11kw nearly 50a each heaters yes 2 of them in same cupboard to power 1 x shower each.
The house is 5 bedroom and is only on a 60a supply anyway.
Didn't work out cable calcs or routes as theres just no point in them.

Why do plumbers and builders have these bright ideas.

Rant over

60a is low for a 5 bedroom, worth having a word with the DNO

Lack of knowledge?
Lack of thought?
Both probably

Any water heater that is instant will always be high wattage .

I have a client with a 5 bed house, annexe, pool, tennis court ......on a 60A fuse

Space and pool heating are gas

It's worked like this for 30 years ....

I bet it didn't start as a five bedroom

A perfect example of diversity working then

If the builder used two of these 9kW instant water heaters;

Strom SEIH9KTS1 Electrical Touch Water Heater Instant Water Heater 9kW - https://www.aquahot.co.uk/strom-seih9kts1-electrical-touch-water-heater-instant-water-heater-9kw

then you might pair them with a priority or a non-priority shower supply board such as:

or

SHOWER PRIORITY UNIT - https://www.eurosales.ie/products/H-1121.html

or

Non priority shower unit Eaton - Online Electrical Wholesaler UK - http://www.electricalwholesaler365.co.uk/Products/Non-Priority-Shower-Unit-Eaton__268224.aspx

These shower priority boards have a maximum load of 40A which is too little to switch the Zip 11kW.

This is not a new property I take it?
Upgraded service cable and a 100A cutout should be the cheapest solution......not!

Would 1 heater be enough for both showers?
