You can change the 2 way priority interlock for a 3 way one. Heres an example: http://www.voltimum.ie/news/8162/cm/abb-s-range-of-priority-non-priority-shower-boards.html its the third one down. The other option would be to put in an electric power shower. This would need a hot and cold feed of equal pressures and it uses very little current compared to an instant shower. The electrical feed for them only needs to be 2.5 square depending on the run. But in an average house this would be fine.

how much that do ya know? i knw it would be easier having a power shower but they want a third one for some stupid reason.

Sorry i wouldn't know how much they are. Never had to get a 3-way one. Ring a wholesalers tomorrow and find out. They might have to order something like that in anyway.

you might be able to add on a relay and contactor -to convert the existing controller( the 3-way is prob pricy )

dunno is a 3-way setup practical really

you also have the nonsense( if memory serves )of the other showers coming back on accidentally

most places use stored hot water and pumps these days

If no Three way unit available, just get a second two way and conect the second output of the first priority unit to the input of the second priority unit and then connect the other two showers to its two outputs.

yes I've heard guys doing this, its a good idea IMHO you select the main shower and wire it into the first o/p of the first unit, then you split the other two not as important showers onto the second unit and feed it from the second o/p of the first unit, I'd forgotten about that one possibly the most cost effective way of doing it, thanks Mat

does it make a difference:)

thought it would be still non-priority with 2 dual controllers

unless i'm missing the obvious

Stoner

well its the best cost solution for the op while staying within in the regs, I though the first unit was a priority unit if its not then I was wrong, but with respect to buying a potentially expensive three op unit the above post offered the most simple solution IMHO that I for one did not think of.

M cebee

ya :)it could be alright

i was thinking of 2 non-priority's

Davy

Does anyone else think its madness putting in three electric showers?

I know switching to a pumped system would have some initial cost, in the long run it would probably save money if using gas central heating to heat the water. Plus you get to have decent showers, and multiple showers at the same time.

M cebee

would be daft adding a 3rd instantaneous shower i reckon

on 12kva

and you have the nonsense of another shower switching on accidentally

not to mention the limescale

Yes a bit over the top i think as well.

2 non priority units will work as a 3 way non priority with the second one fed from the output of the first one. But it seems a bit mad alright to have 3 electric showers in a standard supply house.

Could also have the priority unit with the priority output feeding a non priority unit so the 2 showers on the non priority unit both have priority over the other 1 shower so these 2 are a first come first serve setup over-riding the one other shower. That might be less likely to then interfere with others which would be the case if 1 shower over-rides the other 2.

It all depends what is in the house already which seems to be a priority unit by reading of the OP.
