Is this 7.5kw instant hot water boiler suitable for a mixer shower?
Asked by: Anonymous

I have a large water cylinder with an immersion heater in it. This is only used to supply 2 wash hand basins and the kitchen sink. I am looking to replace the cylinder with this product to supply water to the 3 sinks. Is this an option?.

It is unlikely that this unit will produce enough hot water to satisfy your needs completely, I would consult with a plumber to be sure.

How many outlets can i have coming out?

Asked by: Anonymous
Hi. Thank you for taking an interest in our product. The Strom 7.5kw instant water heater has a recommended flow rate of around 3.6 litres per minute to achieve an output temperature of around 40 degrees Celsius based on a 10 degree incoming mains temperature. There is no limit to how many outlets can be connected to this unit however should more than one outlet be used simultaneously the flow rate passing through the unit should still not exceed the overall recommended flow rate. For example if two hot taps fitted to this unit were running simultaneously then the overall flow rate running through the unit should still be no more than 3.6 litres per minute. Should you want the flow equal at both taps, this would mean you would need to reduce the flow rate at each tap to 1.3 litres a minute to achieve 40 degrees Celsius temperature at both taps. However, you could set the flow rate at both taps to be 3.6 litres per minute and still achieve 40 degrees Celsius at both taps provided they aren't running simultaneously. The amount of outlets and how likely they are to be used simultaneously will always effect this water heaters overall performance but the easiest way to work out whether this product is ideal for you is by ensuring that you are happy with the overall recommended flow rate and you are confident on how you will distribute that flow rate over multiple outlets.
