InSinkErator boiling water taps: all 2 models compared (2026)

US market leader. Near-boiling at 200°F, Home Depot ready.

InSinkErator is the dominant brand in the US instant hot water dispenser market, founded in 1938 and acquired by Whirlpool Corporation in November 2022 (previously owned by Emerson Electric from 1968 to 2022). Its UK instant-hot taps dispense at 98°C (up to 99°C with the NeoTank); the classic US under-sink dispensers run cooler at around 200°F (93°C). Neither reaches a true 100°C. Wide availability through Home Depot and Lowe's. The default choice for US homes.

How the InSinkErator range fits together

We cover 2 InSinkErator boiling water taps, with recommended retail prices from £389 to £899. Both heat to 98°C from a 2.5 litre tank.

The GN1100 (2018) costs £389 and the 3N1 J-Shape (2020) costs £899. Both filter the water, both draw 11 watts on standby and 1,300 watts at peak, and both come in Chrome and Brushed Steel. The price gap is £510. Check the warranty on the model page for the one you are buying, because the cover differs between the two taps.

The GN1100 is a dedicated boiling tap that sits next to the mixer you already have, with two-lever operation. The 3N1 J-Shape delivers mains hot and cold from the same spout as well, and has an adjustable thermostat from 88°C to 98°C. Both come with a 2.5 litre NeoTank under-sink boiler and a filter.

In our data neither tap serves chilled or sparkling water. If you want either, look at the Franke and Zip ranges.

A third InSinkErator, the HOT150, appears in our catalogue as a model sold in the US and not in the UK, so it has no row in the table. Standby power on the two UK taps is low next to the Zip range, which makes the running cost calculator a quick way to see what that means on your own tariff.

For filtered and 4-in-1 taps across all brands, see our instant hot water tap guide. To put a running cost on any of these taps, use the running cost calculator.
