bit of advice pls, wireless remote switch for swimming pool heating system

[Gavin A]

Can I pick your collective brains please for a slightly odd situation I'm struggling to find a solution for.

Essentially a customer of ours has a swimming pool in an outbuilding a few yards from the house, but with a solid patio between the 2 that I'm not wanting to dig up if I can avoid it.

Basically their heating and electric bill is horrendous, mostly from heating the air in the swimming pool on a timer.

I've suggested we fit a remote switch in the house to allow them to switch the air heating on a few minutes before they actually want to have a swim, which I reckon will save them hundreds a year in only heating the pool room for a couple of hours a day when in use instead of the 10 hours a day it's currently timed for in case they want a swim.

problem is that I can't actually seem to find a suitable wireless remote switch relay system - I've seen a few options that need direct line of sight, but nothing that will penetrate a wall (it has to go through the wall into the plant room).

I did try to get them to let us just fit a switch in the pool house, but they weren't having that, so I'm back to trying to locate a suitable wireless remote switch relay system.

If anyone could post a link, or make of any suitable systems you're aware of it'd help a lot as I'm running out of ideas and google and city seem to be stumped.

I think the maximum load to be switched should just be a few hundred watts for the pump and boiler circuit - well under 500W anyway.

Can't remember what they're called, but Maplin are doing a range of home automation RF switches etc that have around a 30m range and are not inexpensive. You could always combine one with a contactor if needs be.

hmm... I tried in Maplin, but I think at the time I was also thinking about incorporating a timer, which I now think is a complication too far.

I'll have another look thanks.

I've used wise box but can't remember what the max switching capabilities are. Really good though

what distance through walls are we looking at, most moder rf system should manage 50-60m through walls

 

[Gavin A]

yeah anything like that would do it.

I have found some stuff but it was all based on switching 13 amp sockets, whereas I want it to be switching a din rail mounted contractor ideally, though I could consider wiring in a socket system if that wasn't available I suppose.
