Has anyone installed a tank less hot water system for their bathroom?
What I want is to be able to use the hot water from the shower point and run hot water to the hand basin,
Do you mean from a “UK style” power shower?
There are smaller undersink versions which draw less power so allowing a lower abbonment 3-6kw usually. Heatraesadia for example. As a sink would generally not require the flow rate of a shower.
Yes, but would have to comply to french regs.
Situated in volume 3 it shouldn’t be a problem apart from a high abonment and possibly tripping the main switch. At 8.5-10.5kw it a bit over the top for a sink.
I am sure Jonathon Badger will pop by and correct me if I am wrong
Tend not to use them in France (power issues?) and I would imagine it would be a bit of an unsightly installation to take a separate output from a power shower and as @Corona said, a bit of an overkill for a bathroom sink. Be interesting to see if you can come up with a solution. Is it not possible to fit a "ballon " to satisfy your domestic hot water requirements?
Sort of. Volume 3 no longer exists - there are only Volumes 0, 1 & 2 (& Volume caché) in any “salles d’eau” these days. The old volume 3 is now part of the wider “hors volume”.
It is permissable to install a Class 1 (earthed) water heater (storage or instant) in Volume 1 as long as it is IPX4 or better & supplied via a 30mA différentiel.
As you rightly state, a high power instantaneous water heater is a very bad idea unless you really want to have a higher abonnement (& thus more expense) than you really need. It’s far better to use a local small balon.
Apologies Jonathan

How have you found it and what do you use it for, sink/shower or bath.
