Krib.ie - Hot Water System

Asdfgh2020

Just wondering has anyone any experience of the above...............?

https://krib.ie/

Had a quick look at web site.........seems a bit expensive for just a controller...?

It seems to be more that just a controller, but still not really sure what it is.

This page says there is a 'KRIB plate heat exchanger system – hot water on demand'.
That implies it is heating the water, so is it like an electric shower for the whole house, only heating water as you need it?
Or maybe it in effect turns a normal boiler into a combi i.e. when request for hot water it signals boiler to turn on and heat the water being used with the heat exchanger.
But it also says about heating the water in the cylinder from the top down so you only heat what you need.

To me its not clear what it is, and generally I'm very sceptic about things that do not have clear information.

It's a SystemLink product and SystemLink have been around for a long time.
I'd agree, the first product looks like a plate exchanger set up which effectively converts your boiler to something like a Combi. But the cylinder set up is probably some sort of circuit loop with multiple temp sensors on the cylinder. I would say their online vagueness is down to trying to avoid it being copied by others.
It has me curious, I might give them a call and drop in to look at it.

Willis make a external immersion heater in which the hot water goes straight to the top of the cylinder (by convection) so it heats from the top down, it will give "hot" water pretty fast but won't heat it to 60c or whatever until the whole cylinder is heated to approx 35/40C, I saw them in the UK years ago and think they were introduced as a cheaper option for HW cylinders that didn't have a immersion tapping originally.

This is pretty much it - heats the cylinder from the top down.

I remember Willis heaters well. But I think the selling point with this is that you can measure the amount of hot water required.

We used to have something like this with a less sophisticated controller (two stats one on heating flow and other at bottom of cylinder). Must have been fitted at same times as Potterton Netheat in 1992. There was a pump and a heat exchanger. It worked well but the heat exchanger eventually went wallop. Could not get a replacement.

It looks very similar to the small Bullet Immersions that you can still get.

I fit one nearly 30 years ago and it's still going strong. One of the best things I ever done in the House.
It heats the water in the Bullet and dumps it into the top of the cylinder.
5 minutes after turning it on you'd have enough hot water to get washed and shaved or wash a few Dishes.
The Longer you leave it on the more hot water you got. 30 Min for most of a Tank.
The temp is controlled by a preset Thermostat.
