Shower (mains fed v tank fed)

yllw.ldbttr

Hi,

Just wondering if anyone has any advice on this.
I'm getting a second electric shower installed this week (upstairs bathroom).
An electrician will be fitting a non priority switch for me also.

The other electric shower (en suite) is tank fed.
The plumber told me to buy a mains fed shower.

I thought the whole point of the tank in the attic is that the water
pressure upstairs would be insufficient to feed an elec shower.
Can anyone clarify before I go ahead and purchase a mains fed shower?


Thanks.

Triton do not rec mains fed showers outside dublin cork or glaway city. Its really down to preference inside these areas.

A mains fed shower is cheaper its only about 160 for the shower as apposed to 250

A mains fed shower is the only shower that you can use in an attic conversion before going down the road of negative head pumps etc.

The reason a mains fed would not be installed over a tank fed is guaranteed security. In otherwords if your mains dies off in pressure the tank fed will work

I'm outside Cork City (about 10 miles) but we are on the mains water supply. The plumber said to go for mains fed but just wanted a second opinion.
Thanks for the response.

I'm in Navan and have a mains shower for 15 years with no problem, well apart from when someone puts on the washing machine when I'm in it..

Ok, so I didn't think of this, presumably the pressure in the shower drops if anyone turns on tap/ dishwasher/ washing machine etc,
and if the pressure drops the flow slows down and the water temp goes up?

Bit of an issue?

Depends on the mains water pressure going into the house.

Poor Mains Pressure = Poor Shower

At times it can be an issue but generally not a problem..

if you have already taken advice from a recommended plumber and electrician why are you asking these questions

I imagine.....A second opinion.... But could be wrong

I would have thought the whole "second opinion" thing would have been obvious (as Joey The Lips said), but erm.... thanks for your contribution.

I've been fitting electric showers for almost 30 years and this is how I decide if the shower should be mains or tank fed.
1) get a pint glass, 2) turn on your cold tap in the kitchen 3) set your stop watch 4) with tap fully opened, time how long it takes to fill a pint glass.
If it takes 4 seconds or less then a mains shower will work fine. at 5/6 seconds it will be affected by other appliences in the house. any longer that that and dont fit one.
Anyway, the only time a mains water shower is better than a tank water shower is in the summer (on a warm day). In the winter you have to slow the water down enough to heat whether it's mains or tank fed so they end up at the same pressure.
Hope that's helpful

Really helpful, thank you very much.
Filled in around 3 seconds so gives me a little bit more confidence.

Cheers.

Any recommendations about the model of the shower?

Triton t80z is a reliable mains fed shower. Costs 190 in woodies and parts are reasonably priced if it needs repairing down the road.
Be careful if buying from b&q, Argus, screwfix or any English company. You need to be sure that the shower is intended for the Irish market. If they aren't them they come without a warranty and you might not be able to get them repaired here

I can't put the link but I found this on woodie's
Triton T80z 9kw Slimline Electric Shower Mains Fed

Sixtoes

I had one of these installed a few weeks ago and it's great.

Only problem is if the water feed drops it'll automatically switch itself to cold. (If dishwasher is being used)

Also because you're being from the UK, Triton Ireland want nothing to do with you.
