What it's made for: a powder room, a garage sink or a tiny house.
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
3.38 GPM max. That is the headline figure, usually at a modest temperature rise. Our calculator counts a shower at 2 GPM, so think one shower at a time.
Safety listing. CSA, ETL or UL certification is named in the listing. Inspectors look for that mark before they sign off.
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.
What the ORBEK 14 kW Electric (240V) listing names:
Breakers and wire gauge are in the installation manual, and it overrides anything above; your electrician reads it first.
At the price on Sep 30, 2026, each kW of stated heating power works out at about $13.57 (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.
Count a plumber's visit and, unless it plugs in, an electrician for the circuit.

Want the shower covered too? The Rheem 18 kW Electric, 240V (9.3/10) is an 18 kW whole-house unit.
Want it to draw only what it needs? The ThermoMate 14 kW Electric, 240V (7.9/10) is self-modulating, per its listing.
Our take
The ORBEK 14 kW Electric (240V) earns its place with up to 3.38 GPM and 14 kW for one tap. No buyer reviews yet, so this ORBEK point-of-use heater has to win you over on paper. Where it falls short: it is built for one tap, and a second fixture opened at once will run lukewarm. We'd pick it if you need one shower or one sink at a time, not the whole house; otherwise, put it next to the ThermoMate 14 kW Electric (240V) first.
6 AWG wire, 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, then leave it.
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 ORBEK 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 ORBEK 14 kW Electric (240V) stacks up against the closest alternative, the ThermoMate 14 kW Electric (240V).
| Criterion | ORBEK 14 kW Electric, 240V | ThermoMate 14 kW Electric, 240V |
|---|---|---|
| Our rating | 7.7/10 | 7.9/10 |
| Max flow | 3.38 GPM | 3.4 GPM |
| Self-modulating | Not stated | Stated |
Pick the ThermoMate 14 kW Electric (240V) if you want our higher-rated option (7.9/10), with more stated flow (3.4 GPM) and self-modulating power.
We rate it 7.7/10 (very good). The rating comes from its documented listing alone, as no customer-review record is captured yet.
The listing states a maximum flow of 3.38 GPM and 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 up to 3.38 GPM and 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.
