Water heater for bathroom shower

Post by Hahuahin »

Probably a stupid question for those who more into this with housing and electricity are. I'm not :oops: But here is the question. In the bathroom we have a Toshiba water heater which says 3500 Watt. If the landlord allows! Will I then be able to get hotter water by installing a Toshiba water heater of 4500-6000Watt?
Thanks in advance for your help

You will as long as your supply can handle the extra amperage - for what you’re looking at you need a 30 amp supply, not 15 amp which is what basic installations are.

TIT, it is called a 15amp supply, because that is the amperage that the meter is calibrated at. The supply is actually good for 30 amps, and usually the consumer board main switch is 63 amps. The correct size breaker for a water heater is 32 amps.

But it then depends on what size breaker, plus the wiring connecting the heater is rated at.
A 6,000 watt heater will draw just on 30 amps at 220 volts. The water may be a bit hotter, but not really worth having the meter spin a lot faster and heat the water a bit quicker depending on the water flow.

I would stick with what you have: depending on the installation a bigger heater may lead to overheated wiring or tripping the breaker if it is not the correct amp rating.

Turning the water flow down can increase the heat of the water, if you have a tap on the shower inlet try that.

Thank you for the replies. Will check with the landlord what amperage and if the electricity system can tolerate a water heater with higher watt.
