quartz
Quartz is a hard, crystalline mineral composed of silica (silicon dioxide). The atoms are linked in a continuous framework of SiO4 silicon-oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar.Quartz exists in two forms, the normal α-quartz and the high-temperature β-quartz, both of which are chiral. The transformation from α-quartz to β-quartz takes place abruptly at 573 °C (846 K; 1,063 °F). Since the transformation is accompanied by a significant change in volume, it can easily induce fracturing of ceramics or rocks passing through this temperature threshold.There are many different varieties of quartz, several of which are classified gemstones. Since antiquity, varieties of quartz have been the most commonly used minerals in the making of jewelry and hardstone carvings, especially in Eurasia.
Quartz is the mineral defining the value of 7 on the Mohs scale of hardness, a qualitative scratch method for determining the hardness of a material to abrasion.
Hi, I thought I'd share my experience of dealing with Aqualisa about their Quartz Digital Diverter.
When selecting the slider rail handset the water would also constantly drip \ stream water from the overhead rain head. When selecting the rain head the pressure was very reduced and the water...
Hello all,
So been having somewhat of a time with my Aqualisa Quartz 9.5 electric shower. A few.month ago I put up with a few problems it was having and in the end I replaced everything, new engine and new front cover . This was working great for a month or so, but now noticed an intermittent...
Hello All,
New to the forum so apologies if do any faux pas. But I have an Aqalisa Electric Quartz Shower 9.5kw (8 years old) and currently it is only giving out cold water regardless of where the temperature control is placed, the only difference is the more you move to the dial to the cold...
Hello all ,
So, very recently had an unvented cylinder put in inplace of the old gravity emersion tank we had, which fed our pumped quartz shower .
We had a new digital processor installed to suit the unvented system but kept the riser rail, showerhead and control unit which we connected to the...
I have just installed a brand new Aqualisa and diverter.
Have a great flow to the hot and cold inlets, which I flushed thought, connected to the supplied iso valves(2) the processor unit, iso valve (1), 90° bend, iso valve(1), diverter, iso valve(2) and then the outlet feeds.
All iso valve are...
We have an Aqualisa Quartz shower that was installed three years ago. Recently, the pressure seems to be lower than it used to be, and you can almost feel it starting to splutter. We descaled the shower head and have also followed advice on the Aqualisa FAQs to run the shower cold and gradually...
I am getting a vehicle charger installed and want to check my cut out fuse is suitable at 60 amps. I have the above shower processor on an unvented cylinder and wondered how much power the shower will use when in use. Does anyone know? I assume it’s not like using a power shower so should be a...
I have a customer who wants an unvented HWS, they have a Aqualisa Quartz Gravity Pumped QZD.A2.EV.14 Shower which has a max pressure of 1 bar.
My question is if I fitted PRV's set at 1 bar, on both H & C services to the shower pump once the UVHWS system is installed, would this be sufficient...
Hi
providing a a quote for a new aqualisa digital shower I have a few questions and hoping someone can help.

Hi, I am considering the purchase of an Acqualisa Quartz Digital power shower but have noticed that the processor specification label says "max on 15 minutes off 45 minutes" Surely if 2 consecutive showers are taken, which could easily total15 minutes, does the next shower user have to wait 45...

Hi
I currently have an aqualisa quartz digital pumped shower installed on a gravity fed system. The cold is fed directly from the cold water storage tank and the hot is taken as the first feed off the hot water supply from the cylinder using an anti gravity loop (no Surrey or Essex flange). I am...

Hello,
My customer has a continuously dripping shower - Aqualisa Quartz A2 - gravity feed - and I am loath to try and dismantle it to try and strip and repair it given the unusual nature of its design and limited technical information that seems to be available.
The black moulding that the hot...
Hey all,tried to fix a friends shower recently. It's the named shower above.
It runs for about 30 seconds then it seems to click and turn itself off. The blue light on the front of the shower no longer lights up at all and it used too. Once it cuts out I can turn it straight back on and it...
Hi, A couple of weeks ago the bottom element on my immersion heater suddenly stopped working. I replaced this with a new one but it didn't work. The boost continued to work for a few days more then this decided to stop working. I have power to the control box, a Pactrol 7 as the led was working...
