Electric shower + electric water heater

[gijno]

Hello, I'm looking to remove cilynder and tank from storage (I want to have empy space there not the cylinder) and I've found one solution on the web, I would like to know if it can be a good one or if it is faulty.

I live in a flat, electricy only, no gas, water pressure around 2 bar.

I would like to put this electric shower

Aqualisa Quartz Graphite Electric Shower 10.5KW

and to heat water for sink in the kitchen and sink + bidet in the bathroom I've seen this water heater (of course I'm gonna buy two of them, on for the kitchen and one for the bathroom)

Redring Powerstream 12KW

If I'm not wrong everything should be used with mains, isn't it? That means I can get rid of cylinder isn't it?

Thanks for your help 🙂

No good for the kitchen sink, to get the water hot enough the flow rate will be dire. It's also a fair old load on the consumer unit.

Is there any alternative, by keeping in mind I would like to remove the cilynder?

Small hot water storage undersink heater rated at 3Kw, do away with the bidet and fit a small handwash unit over the basin.

Mmmm... do not like both handwash unit and keeping away bidet...

You could use a powerstream for the bathroom taps but prepare to be disappointed and ensure that the bidet is an over the rim model.

Disappointed for water pressure, as you said first?

By the way, an over the rim bidet, is like this one?

Yes, got to have a tap with an air gap.

What is it?

 

[Dotty]

A gap of air between the tap and the bidet.

Why am I going to have air tap? Water shouldn't flow "on demand" putting out every air tap which is in the pipes?

 

[Dotty]

Mate, I would suggest you get a couple of quotes of some plumbers local to you or we could be here all night!

And speak to a spark too. That lot adds up to 150 amp without a light on. You will need contactors fitted.

Spark? What is it?
About 150amp, I'm never gonna use all of three items together... should be fine in that way isn't it?

spark=electrician

didn't know that 🙂

Well if you do you will only do it once. 2 at the same time will also cause problems. I hope you live near the fire station to give your neighbours at least some chance of surviving.

Brrr... Is there a maximum amount of Amp I can use without burning London?

 

[tamz]

Of course there is. Your main fuse on the incoming supply will be between 60 and 100 amp.
You need to speak to an electrician. It can be done but not cheaply or easily and not diy.

I understand... basically that means that if I use items once at a time (in any case remaining ALWAYS under the range 60 - 100 amp) it's fine, if for any reason I use more is a problem... isn't it?

 

[Mike Jackson]

A sparky will advise on on the electrics. I'd give one a call first as there are times when the electric supply into the building isn't sufficient. A few years ago I ripped out an electric boiler that a customer had fitted before consulting a sparky. When the sparky turned up to wire it the feed to the building was insufficient for the extra load and the electricity supplier was after thousands to upgrade it.

 

[gijno]

Bad situation...

 

[tamz]

No because there is the possibility someone will use something else at the same time. You also have the load from the rest of the house. Cooker around 30 amp, washing machine 10 amp, sockets up to 30 amp, lights etc etc.
This is not a diy project. Seek professional advice.

 

[Dotty]

There's something called diversification but it also allows for the fact all appliances have the potential to be run at the same time.

How is your place heated?

We are two in a flat so there is low risk to use together things at the same time, anyway is not a risk to undervaluate...

 

[gijno]

How is your place heated?

Electric fireplace (most of the time switched off as thanks to double glazed is quite hot inside)...

 

[tamz]

You have been given the advice. It is dangerous.
You may find you learn an expensive lesson.

 

[Howsie]

Make sure the batteries in your fire alarms are replaced.

First of all I thank all of you for your kind explanation and time... I'm not british so not know well how things work here.
Problems is the last thing I want...

 

[Dotty]

As you've been told, please get tradesmen in and talk to them, tell them what you hope to do.

In all honesty, given what you've told us so far, it's unfeasible, unworkable and downright dangerous.

We are actually all thinking of your safety.

Thanks guys for your honesty 🙂

PS. Any ideas to get rid of cylinder and tank? As said, no combi boiler as I do not have gas...

 

[tamz]

Any scrappie will give you £35 -40 quid for it or leave it on the street for 10 minutes and it will disappear as if by magic.

Your best hope is to get a small unvented hot water cylinder fitted. A small 15l undersink unit will give limited hot water or if you can squeeze in a larger unit you can get them around 60 -70 litres. There is more flexibility in siting them as you don't need any cold water storage. They do need to be fitted by a qualified installer though.

Like this one?

Aqualoy SWSS - 7-15 Litre Stainless Steel Unvented Water Storage Heater | Redring

Which is the best brand?

Can I have two of them, one under the sink in the kitchen and one under the sink in the bathroom (this one shared between sink and bidet)?

 

[Mike Jackson]

That's the sort of thing. You'll need to speak to an electrician again regarding siting one in a bathroom, may need to go in a cupboard due to electrical regulations. They're all fairly similar as far as quality goes.

 

[gijno]

Thanks Mike 🙂

 

[Howsie]

Good luck!

 

[gijno]

Thanks 🙂

 

[gijno]

One more question guys... small unvented hot water cylinder uses water from the mains, isn't it? Actually I have a very good pressure for cold water (about 2 bar)... will I have good water pressure even for hot water?

 

[Mike Jackson]

Yes. ,,,

 

[gijno]

Reading on the web some info about unvented hot water cylinder i've read that they can be risky... is it true? or they are safe?

 

[Dotty]

They are safe only if installed properly by someone who knows what they're doing and holds the g3 qualification.

 

[gijno]

Is there a list where I can have a look at plumbers with G3 qualification nearby my area?

 

[Dotty]

Follow this link mate - [DLMURL="http://www.ukplumbersforums.co.uk/im-looking-plumber-gas-engineer/"]I'm looking for a Plumber or Gas Engineer[/DLMURL]
and post your request there remembering to include your location. One of the guys on here could be close to you.

 

[Dotty]

When you do post I'll put a link in to this thread for you.

 

[gijno]

Done 🙂

Followed your link to this bidet, if this is the one that you have installed then you will not be able to have a mains water supply feeding it. (Water Regs 1999)

 

[gijno]

Hello Chris, thanks for your reply. I do not have installed any bidet yet, I'm still looking for the best solution. Can you please explain me your pic?

 

[chris watkins]

No, not easily. Ask the plumber who you employ. It can only have taps, no hoses or sprays.
