Frequently asked questions

can this unit be used to heat a small bath (120Litres)?
We would recommend a storage heater for a bath of at least 100L.
Does this heater work on 240 volts.
This heater will not work on single phase 240V electricity. It requires 3 phase electricity.
Hi there I'm looking to run two showers off this unit. Would the flow/temperature alter when the second shower is switched on?
The flow rate would be effected if the second shower is switched on. If you want to run two showers at the same time, with no change to the flow rate, we would recommend to use two individual water heaters.
What are the dimensions
The dimensions are H 478mm x W 225mm x D 105mm.
Is there good availability of spares / ongoing maintenance support ? AND can one specify a recent date stamp of manufacture when ordering ?
We do not stock spare parts but Stiebel Eltron are very helpful and have spare parts readily available. Their maintenance support is excellent, and this product does have an onsite warranty. The serial number printed on the water heater is reference to the date stamp of manufacture.
