I thinks that's fine and well, but for a lot of people, they can't afford to think of it in any way other than payback period I eventually want a water recovery system, which recovers pretty much all non drinking water and that just won't pay itself back I also want to make my house passivhaus which again won't be really pay itself back (unless you had it done at the start of the build of the house) For the majority of people, they kinda have to think in terms of payback
@@eFIXXENERGY I looked at the pay off period for a similar bit of kit - it was over 100 years assuming an electric shower with 4 people using it each day for 10 mins... The maths will have changed now electric has doubled of course!
I loved the idea but then it clicked that I have one major concern. how can you get warm water from the very little water I use in a 5 min shower. isn't a shower meant to help save water usage. then I looked up some facts. I'm wrong, seems showers use up to 10 litres of water a min. I did not know that. I'm shocked. think that's something you might want to add to your marketing honesty if I had of known how much water we use for a shower I would never of doubted this video while watching. my new build will have these devices for sure. but I'll also need to look at showers too I didn't know that no matter how high or low you set the heat on the shower it always uses the same amount of electricity. so he says in the videos. so I was having not really warm showers thinking I was saving electricity but I wasn't. the same electricity is used for hot and mild warm?? so really we all need to get better showers that don't waste electricity too as the electricity is generated by mostly nasty ways too. really have to change a lot to be right for the environment.
Good idea - went on to do some research on this. Manufacturers website uses this video as their main marketing footage. Shame the website gives no info on purchasing , both where and when. As this product is not currently available in the UK. Hopefully it is at a price point which is low enough for building developers to install in all new builds
A clever idea but not new and the figures just don't add up. A 10 minute shower at 8kW costs 30p. A one third saving, that's just 10p. Payback time would depend on how many showers you have but assuming a 2 person home taking one shower each a day, that's say 700 showers a year. Savings at 30% let's be generous £125 yearly. It would take a minimum 5 years to recoup the cost of the heat exchanger and that doesn't Include the cost of fitting or any additional cost of repair or maintenance.
One of the things that this can help with is enabling a smaller hot water tanks if your primary hot water consumption is with showers and you're not using an electric shower, but I agree that the figures still just don't add up. The vertical units (recoup WWHRS do a similar one) are better, but very difficult to install in a retrofit situation. These heat recovery units are basically only ever used to increase the SAP scores in new build properties, and for that purpose they're quite a cheap way to go about it, so the price isn't likely to come down any time soon.
I think five years is a pretty good payback period for renewable tech, and that's only going to get shorter as energy prices increase. If you've got more than two people showering it'll pay back quicker as well, maintenance is pretty much zero as there's nothing mechanical or electrical to break down. If it's a new build or you're refurbing your shower it seems like a good and easy contribution to reducing energy use in your home really.
Great idea, but £600 is a nuts price for the horizontal model
Good idea. I suppose you would have to adjust the temperature of the shower as you go.
Yeah, there'd be a bit of adjustment as the process got going. 😊
There are thermostatic shover valve you can use.

Absolutely love your philosophy and ethics here, no harm in saving some pennies while you're at it! 😊
Bravo!

Is it 22mm fitting? I was thinking one of these feeding back into my cylinder for my heat pump.
But what do these units cost ?
I've seen something similar before, but it is an excellent idea and we all should be doing what we can to save our planets resources.
But the cost of this? Madness.
Agreed, thanks for making the journey over to the new channel Brian! 😊
There's usually a pay off period for renewable and retrieval tech. 👍

Do they do a Toilet version to take the heat from from my .......
Not currently no.... also I would suggest, never! 😂
You want to know if there is for the bathtub, is that it? If yes, here is info, thank you -------> www.zypho.pt/specs_izi30_izi40_16.pdf
There are however waste water recovery systems that can be reused for non drinking water
Yellow LED is broken :D
Typical that the only thing not working there was the electrical display!

The higher the energy prices the quicker this pays you back :)
This is a really old idea;
Still a good idea!
