New water heater concept!!?

[gassafe]

I remember awhile ago a forum member saying about this new technology water heater that was amazing & unlike anything else on the market... But would not let on about it, did he ever say what it was as I think I found out what type of heater he was on about today...

18v kettle?

Chalked it was, the company still have not released the product yet

Well this is what I reckon he was on about, but I may be wrong lol...

Yep. That's pretty much the same thing.
The one I saw was about the size of a shoe box. It had 15mm connections and could run 22 lpm @50 degrees using 12kw
They wouldn't show me how it worked, but it had very small waterways (hundreds of them) and it did use graphite heating elements.
The elements look like a plastic film.
I emailed the company a few weeks ago, but they still were a bit off launching the thing.

It will be good for a full bathroom, the temperature is controlled through your phone and was very accurate.

The problem is though with having tiny waterways lime scale was going to be an issue, so they were trying water softners to combat this. But, the heater is made from aircraft grade aluminium, so they were seeing what effect the softner had on this.
I know you can't re- write physics, but this did work.

Had an email from the reseller this morning.
They have put the unit into production, its not the same as the one I saw, but uses the same heating element.
I am waiting on more technical info, but it looks like 6lpm using 6kw, they say it will do 15lpm at 12kw. Looks like they are making a water softner fitted mandatory! So I recon it will be too expensive. I tried to convince them to sell them without a water softner, but put in a testing kit for hard water.
This is the thing.

Hthey say it will do 15lpm at 12kw. [/url]

Only if the incoming main is already warm.

If you run 15 litres per minute through a 12kw appliance, you will only get a 13.33 degree C temp rise, which would be grossly inadequate - barely taking the chill off the cold main in winter.

To get a more adequate 30 or 35 degree rise, you need 28kw to 32kw of input which is why we build combis in this range.

This is straightforward physics, and no amount of clever engineering can circumvent it.

To get decent flows out of this system would require 3 in parallel, or a load well in excess of single phase domestic electrical capacity.

I know you can't re write physics, but I have seen these work!
I too am sceptical, I've seen inside and it's nothing like anything out there. It has 6 carbon heating strips which will each turn on when needed.

I don't think I will be fitting any in the near future as firstly I need to see one working in the real world and the main stumbling block is the price. £1300 at the moment! Without a softner!

Did you check the incoming mains temperature during the demo?

And at that price you'd expect a damn sight better than 15l/min!

I just went on their site, and used the calculator. I set it to 45 degree (F) incoming cold water main and told it that I wanted 2 average showers concurrenly.

Thats about 16-18 litres a minute, and in conventional terms is the point where you have to move from high end combi into a storage solution. It told me I would need 3 units.

They are 45amps each, so that would be a 135amp load.

Bloomin eck!
looks like I've allowed my judgment to be be clouded, as I fell for the blurb and tbh, wanted the thing to work.
they are way too expensive too.

Ps, where is the calculator Ray?

Instant electric water heater. Useless unless you only want small quantities or don't mind mega elec bills!
