What it's made for: a sink that takes forever to run hot.
Two electric tankless heaters of about the same power, closest to it on our rating, each with a dated price.
The heating power the listing states; at 240 V that's about 58 A. On our calculator's maths it gives about 2.2 GPM of 105 °F water when the tap water comes in at 62 °F, and less in winter. Enough for a kitchen or a bathroom sink.
What it has going for it
1 × 60 A breakers. What the listing asks of your panel. That is the line to show your electrician before anything else.
86 to 131 °F. The setpoint range per the listing.
One sink: about 2.2 GPM of 105 °F water with 62 °F tap water, on our calculator's maths. That covers a kitchen or a bathroom sink.
A shower: on paper, with warm tap water, just about (a shower takes about 2 GPM). In January it falls short.
The seller states, word for word, in the SIVUATEK 14 kW Electric (240V) listing:
Requires 1 x 60-amp circuit breaker.
Equipped with an intuitive LED display you can easily set the desired water temperature from 86°F to 131°F in precise 1°F increments.
Their words and their figures, not our measurements. How steady your shower stays when someone opens the kitchen tap, and what's left of that flow in January, no listing can tell you.
What the SIVUATEK 14 kW Electric (240V) listing names:
For the SIVUATEK 14 kW Electric (240V), the installation manual settles the breakers and the wire.
At the price on Sep 30, 2026, each kW of stated heating power works out at about $15.00 (price ÷ stated kW, our arithmetic). That puts it in the cheaper third of the 17 point-of-use heaters we have a price and a stated power for.
Add the circuit to the budget if it doesn't plug in, and an hour of plumbing under the sink.

Our take
The best thing about the SIVUATEK 14 kW Electric (240V) is 14 kW for one tap. No buyer has reviewed it yet, so our 6.9/10 comes from the spec sheet alone. Honestly, the catch: no word on the flow. We'd pick it if the kitchen or the powder-room sink takes forever to run hot; otherwise, put it next to the xwdzswgs 3,000 W Under-Sink (110V) first.
1 new 60 A breakers, the unit on the wall next to the old tank's spot, water in and out. Under a sink or on the wall beside it, close to the tap it feeds.
Hot in a few seconds once the water in the pipes has passed. Set it between 86 and 131 °F.
With 42 °F water coming in, 14 kW gives about 1.5 GPM at 105 °F on our calculator's maths. Low-flow shower heads stretch that further.
Clean the inlet screen and flush out scale on hard water. Our flushing and descaling guide has the routine.
Before the SIVUATEK 14 kW Electric (240V) goes in your cart, check the tap it will feed: 14 kW suits one sink or a low-flow shower.
14 kW warms one sink or one low-flow shower, not two. Decide the fixture first, then check the flow it needs. Our point-of-use guide explains the trade-off.
It runs on 240 V. At 240 V it needs a dedicated circuit; an electrician confirms the breaker and the wire.
Small units need a minimum flow to switch on. Ask the seller for that figure if you have low-flow aerators.
Electric units scale too, mostly at the inlet screen and the element. Our flushing and descaling guide covers the routine.
How the SIVUATEK 14 kW Electric (240V) stacks up against the closest alternative, the xwdzswgs 3,000 W Under-Sink (110V).

Pick the xwdzswgs 3,000 W Under-Sink (110V) if you want our higher-rated option (7.0/10); stay with the SIVUATEK 14 kW Electric (240V) for more power (14 kW).
We rate it 6.9/10 (good). The rating comes from its documented listing alone, as no customer-review record is captured yet.
The listing states a heating power of 14 kW on 240 V. The headline flow is a mild-weather number: with cold winter water coming in, the same unit gives you less. Read the maker's flow chart at your winter rise, or let our flow-rate calculator do the sums.
The listing states 240 V and 14 kW. At 240 V, that is roughly 58 A. A licensed electrician checks the panel, the breakers and the wiring before it goes on the wall.
Its listing states 14 kW for one tap. These are the seller's figures, not our measurements: how steady the temperature is in your shower and how it copes with your winter water can't be read from a listing.
Which tap: 14 kW warms one sink or one low-flow shower, not two. Decide the fixture first, then check the flow it needs. Our point-of-use guide explains the trade-off. Power: it runs on 240 V. At 240 V it needs a dedicated circuit; an electrician confirms the breaker and the wire. Activation flow: small units need a minimum flow to switch on. Ask the seller for that figure if you have low-flow aerators. Scale: electric units scale too, mostly at the inlet screen and the element. Our flushing and descaling guide covers the routine.
