Cable size is easy to check 10mm2 cable is 3.6mm diameter, turn off the supply to the mini consumer unit, drill 2 holes in a piece of wood one 3.5mm in diameter and the other 4mm, the cable should fit in the 4mm hole and not the 3.5, if it won't fit either the cable is OK, assuming you have no vernier gauge or a pair of calipers. my PC is slightly to the right of Genghis

We have instantaneous hot water 415 volts 3 phase 20 amps per phase, 24.9kW. In summer it is too hot, there is a switch on the box to turn off one phase. But I wouldn't want less for winter, the typical water temperature is roughly 12 -15 C in winter.

I would not want it running off a single phase in winter as it would be a very "thin" shower.

Make sure you have the proper size cable, apart from safety, it does make a difference. Our block of units had major repairs and the power supple cable had to be replaced (an entire novel I won't go into). After the new wiring there was a noticeable improvement in the hot water which came out. Have lived in the same place few ages so had a good feel from old to new.

We are required by law to use an electrician, they will check the power supply to the house, cabling etc.


A 24.9kW unit will give you 4.5 litres a minute with the water temperature increased by 45°C Procrastination, mankind's greatest labour saving device!

In the UK the normal domestic supply is single phase 230v 100A incomer, very few houses have 3phase unless converted from commercial premises. my PC is slightly to the right of Genghis

Ive got 3 phses overhead cables attached to my house but only a single phase enters the building, dont know why, all 3 houses on the farm are fed this way At work

My UK house was converted from a timber frame construction yard and workshop, there is a 3 phase meter and a 1 phase to 2 consumer units, one in the house the other in the garage plus a 3 phase breaker and output socket. This may seem over the top but supplying the garage across the patio underground rather than via the house saves about 30metres of cable as it has to go the long way round due to the construction of the floors and ceiling. my PC is slightly to the right of Genghis

about 9 years ago , when I had major reno done on the cottage , had new consumer unit with mcb.s compleate rewire and new supply to bathroom for shower. what was buried in floor and walls was a compleate nightmare..!!!

yes I get that bit but dont know why all 3 houses are on 3 phase all from a central pole hub not in a chain.

still the swallows like all the extra perching areas, so much so there is a no parking zone infront of the house due to the line of droppings, looks great on the pano roof  At work

Possibly due to the location of the pole with respect to the houses, but running 3 phases in a daisy chain to each house has the problem of a neutral line failure of cutting the supply to one or more houses, depending on the failure point. my PC is slightly to the right of Genghis
