What is a good hot water flow rate?
Ideally, the combi boiler flow rate for a good shower should be at least 12 – 15 litres a minute. The flow rate simply refers to how much water can pass through the appliance to feed taps and showers once the boiler is working.
What is a good flow rate for a bath tap?
between 10 and 15 litres per minute

What is a normal gpm for a house?
A toilet will normally use about 2-3 gallons per minute (gpm), a shower from 1.5 to 3.0 gpm, a bathroom or kitchen faucet from 2-3 gpm, a dishwasher from 2-4 gpm, and a washing machine from 3-5 gpm.
How do you calculate hot water flow rate?
Handy rule: multiply the hot water flow rate in litres/minute by the temperature rise in celsius. Divide by 100 and multiply by 7 to get the boiler DHW output in kW. Example: 12 litre/min at 40C rise: 12 x 40 = 480. 480/100 = 4.8.
What flow rate do I need?
If your flow rate is less than 10 litres per minute, you may have what is considered low water pressure. Anywhere between 10 and 15 litres per minute is acceptable but can be improved. A flow above 15 litres per minute is considered good.
