Variable flow Water Pump for instant water heater?

[DuckyUC]

I know the heater restricted the flow to heat the water to designated temp
Place the pump in cold inlet will have no effect

So I try to get the pump install in the hot outlet
get a tune-able pump, Set the pump at lower power to avoid the heating element run dry

It wasnt those high power main boost pump, it is similar to those pump build in storage cylinder which boost the pressure.

it is 12kw and are design for shower, def not sink heater,which normally is 3kw.

albion ultersteel direct unvented cylinders, page 6

120 L cylinder has a recover time of 45 mins with 2x3kw heater
150 L cylinder has a recovery time of 61 mins with 2x3kw heaters

these will be simular figures of other cylinders

also remember the cylinder will start to recover during the first shower not after the second.

so admit your wrong and stop talking rubbish.

38 degrees generally for a shower (can't believe I got sucked in!)

2 shower running at the same time, heating recover from 1st shower already involved in the calculation.

120L/5 will last 24min recharge 45min
210L/5 will last 42min recharge 96min

Thanks for giving the information to support what I said before.

normal shower about 38c-42c

2 standard bath need 210L for direct unit according to the product info you provide.
Which take 96min to reheat, with 5L/min last about 42min.

So far it seem the instant set up still better, wait for 2*20min shower only take 40min.

No normal shower 38 as that is the safety point, if you want it hotter you would need to press a safety switch to unlock to stop people getting burned.
What are you showering, lobsters?
