Rated 1 out of 5 by from Utter rubbish I fitted this as a single point water heater in a shed....utterly pathetic, the temperature is barely....barely above stone cold, totally useless for washing anything......don't waste your money.

Rated 1 out of 5 by from complete waste of time/money after reading the only review on this product I though I could make use of it but even after fitting a caleffi pressure reducing valve, setting that to min so it doesn't even register on the gauge, I still had to turn the iso down half way going into the unit and use the flow reducer on the hot outlet just to reach 41 degrees and its only just more than a dribble no where near the l/min specified. Also I would stay away from strom as I had the handy tap fitted before this and well...WORSE!

Rated 1 out of 5 by from Strom mini instant 3.5kw Specified these to replace Heatrae Sadia handy as we required controlled temperature for vulnerable users. These looked good as had to be less than 4kw to fit to the existing wiring. Just had a call from the contractor advising that he's fitted the first one and performance is pathetic. Water barely trickles out at the chosen temperature. Advised to return the second one and am looking at a low wattage low capacity stored water item. If only the cabling was of a higher rating, could have fitted a ZIp model which are reassuringly expensive.

Does this device require an expansion vessel?

Asked by: Ev26
Hi. Thank you for taking interest in our product. The Strom 3.5kw instant water heater does not require an expansion vessel. An expansion vessel would only be necessary for sealed / unvented systems, it would not be needed for our instantaneous water heater as the heating element in the unit only comes on when the flow switch is activated within the unit. The flow switch can only be activated once the tap is open therefore there would be no expansion in the system.

Can you leave this switched on permanently so it's ready to work on demand, i.e. when the tap is turned on?

Asked by: SwissSimon
Hi. Thank you for taking interest in out product. This product will only draw significant power when it detects water flowing through it. Leaving it on permanently is no issue because of this.

Will this unit feed three hot taps all within 1 metre of the unit

Asked by: Adefrommercian
Hi. Thank you for taking interest in our product. The Strom mini instant 3.5 kw water heater would be sufficient to feed 3 hot taps all with in 1 metre of the unit, however unfortunately the 3.5 kw mini water heater we would only recommend for single point use of application. The reason for this would be due to the flow rates required to achieve a strong temperature. The recommended flow rate for this product is 1.2L a minute to achieve around a 40 degree temperature. Should all 3 taps be running simultaneously then each tap would need to be set at a flow rate of 0.4L a minute which would be unfit for purpose. You may benefit from having a look at our range of touch screen and digital water heaters ranging from 5.5 kw to 11.0 kw which we would recommend for multi point applications. Take care of noticing which units have what recommended flow rate so it is easier to decide which one is best for you.

Can this be used for a kitchen tap?

Asked by: Anonymous
Hi. Thank you for taking an interest in our product. We would not recommend this product to be used as a kitchen tap as this product has been specifically designed for hand washing. This product has a recommended flow rate of 1.2 litres per minute at a temperature of around 40 degrees Celsius based on a 10 degree incoming mains temperature. If for example you wanted to use this product for washing pots, an average washing bowl has a capacity of 9 litres, this means it would take between 7 to 8 minutes to fill the washing bowl and within this time there is a chance you would start experiencing heat loss within the water inside the water bowl.

Hi does this water heater come with a spout (length of spout )like to fit over a wash hand basin.

Asked by: totalmick
Thank you for your enquiry and interest in this product. I'm afraid the unit does not come with an additional spout. The unit has cold in and hot out threads at its base. The cold mains will supply the unit at the cold in and the hot out will then supply a tap. Kind regards.
