Hello,

I was wondering whether to put the bathroom rads on a separate CH
zone, rather than connecting them to the upstairs zone. I'm thinking
this way I could heat the towels in the summer without heating the
bedrooms.

Is this a good idea? If so, how would I control the 2 port-valve?
Normally I would use a thermostat but can you use thermostats in a
bathroom? I'm thinking not because of (i) electrical requirements
(unless outside zone 2 or wireless) and (ii) wouldn't the humidity be
an issue?

Would you just run the circuit off a timer? Could I use TRVs or would
TRVs switch off the rad when the room was warm but before the towels
were warm?

Thanks,
Stephen.

AIUI it's 'normal' to fit the bathroom radiator before any control valves
(mine is) such that the bathroom rad gets hot whenever the boiler runs -
it's often used as the boiler bypass. Therefore during the summer the
towels dry when the boiler is heating the HW.

Why not just take a feed from the flow pipe *before* the zone valves? This
way, this rad will get hot whenever one or more zones - including HW - are
receiving heat, and won't need any exta valves or stats.

Hi there Stephen

I was wondering if you had considered the Dual Fuel option? It would
be far simpler for you than trying to reconfigure the way your heating
works. Most people want to shut their central heating off completely
during the summer, as it's inefficient to keep it running, just for
one radiator in your home.

I recommend that you consider one of the central-heated towel rails,
with an electric element so that you can use the bathroom radiator
during the summer months. Most of our central heated towel rails can
be converted to Dual Fuel with a kit that we can send out. Here is an
example of the kind of thing we mean:

Hope this helps

That's ok if you happen to like towel rads rather than *proper* rads - but
bear in mind that, size for size, they only produce a fraction of the heat
output of the real thing.

That's true if you're thinking about the modern ladder towel rails.
There are other towel rails that have a more traditional inset
radiator, such as the british-made
http://www.tradeplumbing.co.uk/Elect...p_36-6287.html
which has an output of over 3000BTUs.

In conventional radiator terms, to get such an output, you'd need to
have a single panel 500 x 1100mm or a double panel 500 x 600mm.

There are timers and thermostatic controls available for this type of
radiator.

Didn't really want to get too technical here, but I hope this
reassures you that it's the simplest option.

If there is space it is wise to separate heating the bathroom from
drying towels. A towel rail separate from the radiator allows towels
to be dried all year round, without overheating the bathroom in
summer.

It is worthwhile fitting an electric element to most towel rails.
Whether it is best to use this or the heating system to warm up the
towel rail in summer depends on the efficiency of the heating
system. Many of these are very inefficient on low loads, but some
are not.

There are splash resistant thermostats, for example
http://www.tlc-direct.co.uk/Products/TCWS10.html but an "ordinary"
one can often be fitted if it is in the right place. See the 17th
Edition for guidance.

I have separate 2-port valves and timer/stats for every room (it really
does give a flexible system!) I've had no problems with the bathroom stat
in five years (and with three kids having baths and no extractor, the
humidity is high!)

Safety wise, the stats are battery powered and I have them switching 12V
relays supplied by an isolating transformer with earthed screen - as well
as making the system safe for the bathroom, it also allows the use of alarm
cable for neat installation in rooms that are already decorated.
