HELP please! Timer socket with 3 remote controls

Hi,  I wonder if anyone can help..... NB I'm NOT an electrician, or engineer, nor am I any good at DIY! I've tried searching the internet for such a product but with no luck, so I thought I'd ask for help.

I’m looking for a plug socket with two or three wireless remote control devices (buttons) with a countdown timer, probably 15 minutes.

My issue is that hot water takes AGES to come through the pipes. I have a hot water circulation pump that I can turn on and this helps the problem, BUT a) this wastes a lot of hot water and b) I can’t use it for very long with my hot water system.

SO, I decided to use a simple countdown timer socket which the pump plugs into. (The timer socket is called an: Energenie 30 minute run down timer plug). This works well but I have to go to the airing cupboard each time to press the button, which isn’t ideal obviously.

SO, I’ve been looking for a timer socket that could be controlled by remote control buttons. I’d like 3 remote control buttons (kitchen and two bathrooms). I’d like to be able to press the button and the pump would come on and then switch off again after 15 minutes.

As I said, I've tried searching the internet such a product and can find lots of things (smart devices) for use with Alexa, or a phone, but I don't want to use any of those, I just want a simple button or light switch style remote control.

Can anyone suggest where I could buy something like this please? Or, am I asking on the wrong sort of forum in which case where should I go for advice?

Many thanks in advance,
Belinda
