The pump for my secondary loop plugs into a regular 13A socket. The electrician recommended I use a smart plug with it, so that I can set up a routine like 4 minutes on out of every 12 minutes for the hours that we are in the house and awake. Something like a TP Link Kasa plug would probably be able to do that, but I'm thinking it would be better to have something that doesn't rely on wifi, that way the secondary loop doesn't depend on Virgin Media, which are pretty unreliable. I have a basic rotary timer that I picked up in aldi for £4, but it can only do units of 15 minutes, which won't work. I think I need something much more intermitent than that, like 4min/12min or 5min/15min.
For those that have installed a a secondary loop, what timer did you use for your pump and what settings did you set it to?
