I am wondering what the difference is between a 6000 wattt Electric Shower unit and a 3500 watt unit??

is the 6000 watt better and will the water get hotter because its 6000 watt??

I dont know anything about electricity so sorry if this is a stupid question.

yes!

The Watt shows how much power it has (and use). IF you have very low water pressure, not much water comes out when you take shower a 3500 Watt will get it very hot as well.

But if you have a strong pump than 3500 Watt might get you the water only little bit warm but not hot.

So if you want strong very hot showers take the 6000 Watt.

Else 3500 is also OK.

If your electric wiring is not good, or you have on the same wires already the aircondition and the washing machine than the 6000 Watt will burn out the wire while the 3500 only maybe burn it out :-))

When you install it it MUST have a ground wire. And most of the Thais don't care about it until they get a bad electro-shock.

Most people like their showers at a bit above bloodheat. In the Central districts where the water start temperature is never very cold any will do. 6000 watt will allow a stronger shower.

In hill country in the cold season you may only he able to heat a very low flow of water adequately with a small one. I have a 6000 watt one in Chiangrai and it gives a beautiful shower.

If you have very light wiring the 6000 watt one may pull too much but if the house is wired reasonably it should be ok. I would be careful about having heavy drain equipment on at the same time though.

The Wattage basically means how quick and hot it will heat the water.

It has no bearing on the water pressure.

For a 6kw shower you should be looking to provide a dedicated circuit from the distribution box at 6mm2 CSA Ideally protected by at most a 30ma RCD and 32Amp MCB or 32a RCBO.

You will require an Earth/ground that has an actual path to earth/ground.

Its a personal thing/decision.

We have the usual 3500W heater and its enough for me.

Don't need a very hot shower (its unhealthy anyway).

If your pump is "too strong", all those heaters have a pressure reducing valve to adapt the flow.

It does have a bearing on the pressure. If you turn the tap on full it will not heat the water to the correct temperature. If you have a trickle the water may be too hot. Low watage heaters can only heat a low flow satisfactoraly.

3000 W is enough for me, and i dont know of any one that has less tolerance for cold

showers should have independent feeds to your consumer unit, and be earthed,
