Tixx 8500W portable review: the most power, the most wiring

The Tixx 8500W portable is our Best portable pick: 8,500W, the highest rated power we rank, in a unit that serves a kitchen sink as well as a shower, at around ₱5,900.

What does 8,500W buy, and what does it cost?

More hot water per minute than anything else here. An instant heater warms water as it flows, so wattage sets throughput: at 8,500W you can open the tap further and still get properly hot water, which is what makes a shower feel strong rather than adequate.

The price of that is electrical, and it is steep. 8,500W at 220V draws roughly 39 amps. That is the heaviest load in this roundup, well past the 29.5A of the 6,500W units and more than double the 15A of the Panasonic DH-3VS1PW.

Thirty-nine amps needs a large dedicated breaker and thick wire, sized by an electrician. This is emphatically not a unit you connect to an existing bathroom or kitchen circuit.

Which brings up the word on the listing that deserves care. Portable here means the unit is designed to be moved between points of use rather than permanently plumbed to one shower. It does not mean you can plug it in anywhere. The 39-amp requirement travels with it, so every location it serves needs a circuit rated for the load.

What is not published?

No IP rating. No ELCB or earth leakage protection. No flow rate. No warranty period.

On this particular unit, the missing earth leakage protection deserves more weight than usual. A movable appliance sees more handling, more connection and disconnection, and more opportunity for a cable or fitting to be damaged, and it is being used near a kitchen sink as well as in a bathroom.

Fit an RCD or ELCB at the panel and confirm the ground before this is used at all. At 39 amps in wet locations, that is not a nice-to-have.

The missing flow rate is the other real gap, because on a heater sold on raw power, litres per minute is the number that would prove it.

Is this shower heater sulit?

Around ₱5,900 as of August 27, 2026. Check the latest price on Shopee.

That is four times the price of the ₱1,400 house-brand units and roughly ₱2,200 less than the Panasonic DH-3VS1PW, and the comparison with the Panasonic is the instructive one.

The Panasonic delivers less hot water per minute at 3.5kW, but it publishes nine safety points, ships a proper shower head, works on existing wiring, and has a nationwide service network. This delivers far more throughput and publishes nothing, and needs the most expensive installation in the category.

So the honest position: this is a specialist purchase. If you have, or are willing to pay for, a circuit rated at 39 amps and you genuinely need high flow at more than one point of use, it does something nothing else here does. If you are shopping on price or on safety documentation, it is the wrong unit.

The 5.0 rating rests on 5 raters against 13 units sold, which is far too small a sample to lean on.

Who this shower heater suits

Buy this if you are having proper electrical work done anyway and want high-flow hot water at more than one point in the house. It is the right choice for a home renovation where an electrician is already sizing circuits, or a small business needing hot water at a sink and a shower. If you are not budgeting for that wiring, buy a 3.5kW unit and get a hot shower for less money and far less risk.

Other shower heater options to compare

If you want strong hot water without a 39-amp circuit, the Panasonic DH-3VS1PW runs at 3.5kW with nine published safety points at around ₱8,100. If you need hot water at two outlets with published ELCB and IP25 protection, the Panasonic DH-6SM1PW is the multipoint answer at around ₱14,200.
