I been looking at various gadgets to limit the cost of hot water and water flow after our combined annual spend on power and water has doubled in our household during the last few years.. Having a conversation with the long shower culprits about carbon footprint and need to be green does not seem to get through to my three teenage children. So I am looking at various options that can help limit the power / water flow. So far I looked at couple of cheap solutions (e.g. the flow limiter's like Eco-Stream Multispray ECO MSHSS cp from Mitre 10 at $175) to custom gadgets that need plumbing / wiring (e.g. Showersmart @$375 from factory in Auckland) Does anyone got any experience with any of the gadgets available in NZ?

I done something similar for a friend, he hosts home stay students and they are terrible for using all the hot water, any way he was upgrading his bathroom, so a programable timer was installed, turn your shower on, push the button, 8 mins of hot water, 8 mins of no hot water - even if you press the button again, still got to wait for the 8 mins. It was quite pricy, it did mean having to knock a hole in the wall to access the pipework, but the bathroom was been re-done anyway. He is very happy with it

I have such a device at home, it usually comes free with the house... The toilet, I love this one! When I was young we had a device that stuck to the wall, when it felt the vibration of the water flowing it started to time, after 5 min it would buzz. It didn't stop the hot water but let you know that you had been in for 5 min. I know a little more than nothing but not much...

No ideas around gadgets but I do remember once, my brother had been in the shower for far too long so dad went to the cylinder and turned the main valve off :P

They would be very quick showers! ----------------------------------------------------------------------------------------------- Nothing is impossible for the man who doesn't have to do it it himself - A.

I remember a friends dad when we were young had a sheep dip timer in the bathroom - it didn't stop the water flow, but was bloody loud so you got out of the shower quick to stop it! Good low tech kiwi solution

The tried and true method of a clip-round-the-ears use to work wonders. It was cheap and very effective. Damn you Sue Bradford! Artificial intelligence is no match, for natural stupidity!

The kids are well left home now but I was known to apply the bucket of cold water over the top of the shower door on occasions The alternative if they had left their shower window open was a nearby hose which could be directed through the window.

What is your hot water set up? If it is a regular electric cylinder, then there is a valve on the cylinder outlet that you can turn off , it will turn off all the hot water in the house ( but you can turn it back on again once they are out of the shower) If it is a gas powered continuous flow, then you can turn off the power to the unit at the switch( but you will have to go out side to do it), I think that you should firstly get a decent countdown timer and put it in the Room with the shower, Give everyone a week's warning that if they exceed the time limit, then you will turn off the hot water to the shower, It will require a bit of effort on your part, but like everything with kids they will get it eventually,

wellygary: If it is a gas powered continuous flow, then you can turn off the power to the unit at the switch( but you will have to go out side to do it), if its a gas powered continuous flow, you can have a controller that stops delivering water after X litres are delivered. for example: http://www.rinnai.co.nz/product_60_rinnai_continuous_flow_controller_-_bathroom_deluxe.html Need help implementing Microsoft CRM?

During the water shortages in Australia they gave us egg timers with suction cups to stick to the shower wall. Not every machine has to have a microprocessor :)

Not every machine has to have a microprocessor :) due to unforseen problems the organic microprocessor fails to take notice of the ding of the egg timer and keeps on enjoying the long hot shower

Well we have something called a "shower reducer", and it is a small little circle that goes in between the shower head and the shower hose. This limits the amount of water going out through the shower head. Me: My TechSite - NZ TechBlog A bit about Me My Twitter My Geekzone blog

I would just smack an electronic solenoid in and then control it with an Arduino. have a button next to the light switch that starts the timer and open the solenoid and then shuts it off for x amount of minutes after the time is up so they can't just press the button again. Would be super simple. Hardest (and probably most expensive) part would be installing the solenoid.

Give them the option of short showers in your house or long showers in their own house :P That said we have had a number of home stay students over time and while some were incredibly courteous there was a few that could not be re-programmed
