Family friend has had an old storage heater in bathroom.It packed up
so a firm has fitted them a new one. It is rated for use in bathrooms
but is exactly half the size needed to heat the room and they way
overcharged for the privedge.
It does have no control switches unlike the correct sized heater.the
heater is about 85cms from fixed bath...and is on economy 7,but only
prtected by a wired wylex fuse.Also in the bathroom is one of those
olde worlde ring radiant heaters and that IS within 60cms of the
bath,with a low ceiling height to boot.would the corrected sized
heater protected by a rcd spur ,and remove the light,for a splashproof
bulkhead be an OK answer?
I am going to sound out my pet electrian tomorow,part P and wll
that.thanks in advance

In article <c71d84e4-188e-44d6...@10g2000vbu.googlegroups.com>,
regardless how big they are? ;-) In this country at least.
Dad had a flat in Paris, and that had one giant storage heater in
the central hallway, which was big enough to heat the whole flat
for over a day on a full charge, and so worked well. The ones fitted
in this country never seem to though - always much too small.

It sounds like a room which was probably wired to the
14th Ed regs (without actually digging out my 14th Ed regs).
Replacing the storage heater like-for-like providing things
like the equipotential bonding are all in place is still OK today.
If you want to bring it up to 17th Edition regs, you really need
to do the whole room, and that's going to be more than one circuit.
The regs are not designed with a view of mixing different editions
in the same circuits, or same bathroom. Even in the overlap
periods between editions, you must use entirely one or the other.

Aren't they always exactly half the size needed to heat the room,

switches.
If there is another heater, it will be fine for background heat and
will only fall short in very cold weather.

What heater you can fit comes down to the zones.
In a small bathroom you are probably limited to a TSR9AW (single element) storage heater, if insufficient fit a pullcord operated fan wall heater with perhaps runback timer set to 5-10-15mins etc (FX20VL).
In a large bathroom, such as ensuite conversion of a very large room, it may be possible to locate the heater and controls far outside the zones so any may be fitted.
Very true re undersized heaters.
- Conventional storage heaters require 2006 levels of insulation
- Conventional storage heaters do not work well, however, with 2012 levels of insulation because the room stays too hot - door must be left open 24/7. In this instance you need fan storage heaters such as Elnur 2kW 3kW 4kW ADL-4012 etc which use a fan to pull heat out on call from a separate wall mounted thermostat. Unfortunately the addition of more insulation & fan pushes the price even higher. An alternative is to deliberately use an undersized conventional storage heater - with on-demand peak heating on a decent thermostat. Dimplex Duoheat combine both, but I am wary of their reliability re PCBs, thin film element and so on.
Bathrooms cry out for wall mounted IPx4 fan heaters unless well insulated :-)
