Stiebel Eltron SN 5 SL GB Vented Oversink Water Heater
Combining the efficiency of storing hot water with the ease of an over sink hand wash design, this heater is perfect for areas which are in high-demand, such as bathrooms or food preparation kitchens for small businesses.
Temperature can be adjustable between 35 and 85 degrees, so a consistent flow of water is available at all times. A thermal cut out ability, which can be set at 38, 45, 55 or 65°C, makes it great if several different people will be using it, such as in a public setting.
To keep running costs low, there is highly effective thermal insulation in place. This keeps the heat inside the boiler, so none of the energy that went into the heating process was wasted. Standby consumption is low, and there is also an eco setting. This averages 60°C – seen as the ideal temperature for effective washing.
The latest ‘Drop Stop Function’ technology means that an expansion tank is not required. Any water expansion is taken up in the tank and not through the tap. This also means less heat is lost, water doesn’t drip and limescale won’t build up.
Because it is a tank model, once it has been emptied it takes a little while to refill and reheat. A full tank takes around 15 minutes, so it is best for an area which sees demand but not to the level where this hot water wouldn’t be able to replenish.
- Good temperature control
- Modern style
Clean design, simple to use and perfect for those areas where a smaller hand wash heater just won’t do. The price is also incredibly generous
- Capacity: 5L
- Power Output: 2kW
- Dimensions: 26.3 x 42.1 x 23 cm

Triton T30i 3kW Handwash
When only a cold water supply is given, the usability of a sink is suddenly reduced. It can’t be used for hand washing for one, which is not ideal if it is in a bathroom or kitchen environment.
This Triton over sink hand wash facility sorts that out. A single on/off and temperature control dial and 200mm swivel arm give a great amount of control to the user. It is compact, so if you want it to remain quite unobtrusive, it is an ideal model.
A standout selling point is the price. It might not be the absolute best heater in terms of power and water supply, but for the cost, it is a product which does the job. You can buy in bulk too, so if you need a couple of tanks as you want to kit out the whole home or have outside studios, you’re good to go.
As the temperature increases, the flow rate decreases slightly. It is still comfortable for washing hands, but if you need to fill buckets or sinks, then you may have to wait a little while. The additional shower head fitting gives more pressure, so it is best to always use it with this in place.
This is our only little issue though. Overall, for the price, you can’t really wish for more.
- Dial is easy to turn and adjust
Best for washing hands, it is easy and clear to use and won’t look completely out of place either
- Flow Rate: 0.8L – 2L per min
- Power Output: 3kW
- Dimensions: 30.4 x 25.4 x 18 cm

Hyco Oversink 5 Litre Tank Handy Flow
If you need a large amount of hot water frequently, such as in a workshop or food production environment, then an over sink tank which stores the water could be the best option.
It is lightweight and can be installed easily, which cuts a lot of the effort out. The overall size is relatively slimline and non-bulky too so that it won’t stand out too much.
As a point of use tank, it is best for hand or dishwashing at a single sink. Talking of garages and outbuildings, it doesn’t only monitor its internal temperature but also that of the external environment. A frost protection setting will ensure it still works well when the heat in the room dips, so you’ll still have perfectly hot water.
The 1m long power cable is pre-fitted to save time during installation, and a wall fixing bracket is included. A white corrosion-proof case will keep it looking as good as new for years to come. There’s also no need for an expansion vessel as it is all done automatically.
Because it is a tank, if you need to fill a bucket or sink it’s best to turn the temperature quite high. When the cooler water kicks in, it will still be hot overall. You also won’t get the full 5L capacity of hot water. But it likely won’t be too much of an issue for your needs.
- Heats water relatively quickly
The perfect size for hand washing areas. Not the nicest to look at but comes in at a good price
- Capacity: 5L
- Power Output: 2kW
- Dimensions: 45 x 28 x 18.6 cm

Stiebel Eltron Handwash Water Heater
Working on demand to deliver hot water when required, this hand wash heater is compact and safe to use.
There is a temperature safety cut-out at 52⁰C, which resets when it is back to 42⁰C. If it is going to be used in an environment where several people will be using it, such as a bathroom of a workplace, this is ideal as it reduces the risk of accidents. The temperature stabiliser will ensure both the temperature and pressure remain consistent, too.
The dial is easy to turn too, which makes it good for multi-person use. Thanks to the large grip, people can adjust the settings to suit their own preferences, even with wet hands.
When the temperature is increased, the flow rate reduces slightly to allow this to be reached. It then increases when the heat is lowered if you need a bit more power. This does mean that at the hottest setting, it is more of a trickle than a jet of water, but it still does the job.
It won’t consume any energy when on standby, so is a cost-effective heater to run. It is also pretty budget friendly to purchase, so in all a great solution to your hot water woes.
- Safety cut out
- Dial easy to turn
- Despite being for safety, many competitors reach much higher temperatures
Simple to use and featuring a basic design which can be accommodated anywhere. We liked the concealed connections at the bottom of the device for an even cleaner look
- Flow Rate: N/A Power
- Output: 3kW
- Dimensions: 8.5 x 23.5 x 15.1 cm

Thanks to the innovative Vortex technology, the flow rate from this water heater isn’t only improved, but the likelihood of limescale is reduced too. Perfect if you live in a hard water area.
Hard water can often be difficult to deal with using such products. The fact that this design has combated issues to a certain degree is welcomed. There is a single dial for the on/off function and temperature control, for easy use.
A sprinkler on the bottom of the arm is good for thorough hand washing. This can be removed if you prefer a steadier stream. Because there isn’t much power given out, it is best for hand washing as opposed to filling sinks or buckets.
There is a red power light which comes on when the heating elements are getting to work for safety. From the switched off position, you rotate the dial anti-clockwise to get the hot water first and then the cold. Hot water takes less than ten seconds to properly start emerging which is a good time.
The delivery tube is 8cm long which is generous and can be swivelled a full 360, degrees so the user has full control.
It needs to be hard wired as opposed to plugging it in so an electrician will need to be booked. The actual price of the heater is good though so this should balance out, and the instructions are easy to follow. Other reviews mention the fact that your home/building must have good water pressure to help it work at its optimum, however. So if this is for an outbuilding or basement area, you may have to reconsider. It also can’t be positioned in areas which may be affected by frost or low temperatures.
- Easy to operate
- Good to install
- Design is a bit dated
- Requires great water pressure levels
A good price and easy to navigate. We have a few little issues, and it isn’t suitable for every home or building, but the price is still worth the purchase
- Flow Rate: N/A
- Power Output: 3kW
- Dimensions: 25.1 x 14.1 x 11.4 cm
