Hi all

I have a question on hot water cylnders.
i am connecting 2 hotwater cylinders which are 3 kw, 40 years old house is under renovating , old cylinders were 2kw(total 4kw).
there is rewirabe fuse in the metre box, 2 hrc fuse in the sb.. pilot is 4mm.
can we connect 2 cylinders(total 6kw) with 1 ripple control. very appreciated with your vauable advices.

on local network's rules.
and size of w/h main between meterbox and swbd.

Most ripples are good for 40 A but some networks want them restricted to 32 A.

6 kW should be OK on ripple even with that restriction; but whether 6 kW will fit on mains depends on size / route length / installation conditions.
