HKM-137235 Digital Electric Kettle with High Borosilicate Glass and Two-Layer Jug for Safe Boiling

HKM-137235 · Electric Kettles · Borosilicate Glass, Two Tiers, Grey or Black

Two Glass Tiers, Plunger Filter

HKM-137235 is a two-tier glass kettle: a lower jug that sits on the digital base and boils, and an upper brew chamber that lifts off, carrying its own handle, spout, lid and a stainless mesh basket on a plunger rod. Both tiers are high borosilicate glass, the lower one wrapped in a slotted outer shell, and the base carries a display for temperature, timing and water type.

It suits a desk or a small kitchen where one vessel is expected to boil the water and brew the tea in the same footprint. The upper chamber is the part that moves: it can be filled, loaded with leaf and set back on the lower jug, and the plunger presses the basket down through the water rather than the water through the leaf.

At a Glance

• Type — two-tier glass kettle with brew chamber, cordless jug
• Material — high borosilicate glass, stainless trim and filter
• Filter — stainless mesh basket on a plunger rod
• Base — digital display: temperature, timing, water type
• Colours — grey or black trim, both at the same price
• Published figures — capacity and wattage are not stated in the listing

Materials and Construction

Both tiers are high borosilicate glass, chosen for its resistance to thermal shock — the reason a glass vessel can take boiling water without crazing. The lower jug is sleeved in a slotted plastic shell that leaves vertical windows of glass showing, so the water level is visible while the hand is shielded from the wall; the design sketch in the gallery labels that construction as plastic over glass.

The upper chamber is a plain glass cylinder with a stainless collar at its foot, a moulded handle and a short spout at the rim. Its lid is a glass disc with a brushed knob, and through the centre runs a rod ending in a stainless mesh basket: pressing the knob drives the basket down, lifting it draws the basket back up.

• The base is a rounded square plate with a brushed rim and a black glass panel across the front.
• The panel shows temperature in large digits, a timing icon, a purified-water icon and a tap-water icon, with a °C/°F key and a power key.
• The jug sits on the plate without a locking pin, so it can be set back at any rotation.

How It Works

Water goes into the lower jug, which is set on the base and heated; the panel shows the temperature as it climbs, with the scale switchable between °C and °F. The icons along the panel name the functions rather than the temperatures: timing, purified water and tap water, each with its own key beside the display. No preset temperatures are printed, and no wattage is published, so neither is claimed here.

Brewing happens in the upper tier. Leaf goes into the mesh basket, the chamber is set on the lower jug, and hot water is added; the plunger is then pressed to drive the basket down through the liquor, which is the reverse of a French press, where the plunger pushes the grounds down and the water stays put. Lifting the rod draws the basket clear so the infusion stops.

The upper chamber is also the serving vessel. It has its own handle and spout, so it can be lifted off the base and poured at the table while the lower jug stays on the plate, and the two tiers separate for washing.

Placement and Use

The footprint is a base plate plus the height of two stacked glass tiers, so it wants open counter rather than space under a cabinet. Leave room above the upper lid for lifting the chamber off, and keep the base on a dry surface — the panel is glass and the plate is open at the seam.

• Fill the lower jug below its maximum window; the upper chamber sits on the collar, not in the water.
• Seat the upper chamber squarely before pressing the plunger, so the basket travels straight.
• Lift the chamber by its handle rather than the lid knob, which is the plunger, not a grip.

Included and Optional

Colours and Finishes

Two trim colours are sold at the same price: grey and black. The colour is carried by the moulded parts — the handles, the collar, the lid knob and the slot frame on the lower jug — while the glass stays clear and the stainless stays brushed, so the difference between the two is confined to the furniture of the object.

No coating is described for the glass in the listing, and none is applied: the only finishes named are the brushed steel of the collars and the moulded colour of the trim. The panel on the base is black glass in both versions.

Care and Maintenance

Both glass tiers wash by hand with warm water and a soft brush; the mesh basket needs a brush to clear the leaf that packs against it. Neither tier should go in a dishwasher, and neither should be set down hot on a cold stone surface — the point of borosilicate is that it tolerates a wide band of temperature, not that it tolerates a shock across a wet worktop.

Descale the lower jug with white vinegar and water when a film appears on the glass, then boil fresh water and rinse twice. Wipe the base with a dry cloth; the panel is a membrane keypad under glass, and water pressed across it is the usual cause of a key that stops responding.
