How to log how long a heating pump has been runnin? Ideas???

[ashnook]

I want to see how long my UFH is on for over a period of time. I do not want to
know when but just '3 hours today' or ' 35 hours this week' etc.

I was thinking of something connected in parallel with the manifold pump would
do but I cannot fined a timer suitable. I just want to accumulate time.

Any ideas?
Thanks, Brian

Something like a small plc? Siemens has a series called LOGO. Fairly easy to program, and with some models, you can connect the inputs directly on the line voltage.

If it's plug-in pump (or if you can rewire it to go via a plug) then you could try using a plug-top energy meter to record the cumulative consumption of the pump and derive the runtime from that. You'd need to get a meter which had battery backup for its readings, and which had a suitable power rating for the pump load, of course...

Alternatively, if you could find a mains-powered analogue clock, wiring that up to the pump supply would give you a simple 12 hour cumulative time display.
