RE: Re: Automated motorised water valves

[Marcus Warrington <marcus.warrington@xxxxxxxxxx>]

I do a very similar thing, but I have used a termostatic mixer valve
under the bath to set a fixed temperature with a radiator zoning valve
after it to turn on/off the water flow.  Only issue so far is that I find
the radiator valve doesn't fully stop the water flow and small drops of
water still drip out of the tap over time (only about 1 drop every 2-3
minutes). I thought those RSS valves only had a maximum ON time of around
3minutes (before they overheat?), our bath takes about 10 minutes to
fillup.

Very basic really, I have the temperature set at the combi boiler near max
and generally fill the bath with hot water only......I need the hot
temperature to help release my joints. Cold is set for short duration, if
required. Very very basic control, as I haven't really had time to work on
it more....SWMBO has a list of work which at my pace, keeps getting longer.

When I replace the bathroom, I'm hoping to put in full automation, subject
to something being available at reasonable cost.

Interesting application :-)
How do you ensure the temperature of the bathwater is correct if these
are just on/off valves?

Thanks,

Tim.
