hi all, we have a remeha avanta boiler and we can only get luke warm water if the tap is on full. if we only put it on half then its absolutely fine. theres no error codes or anything, anyone have a clue what it could be?
Presumably you have a combi boiler. Which version of the Avanta is it?hi all, we have a remeha avanta boiler and we can only get luke warm water if the tap is on full. if we only put it on half then its absolutely fine. theres no error codes or anything, anyone have a clue what it could be?
The model will be on the data plate, which is on the underside of the boiler. It should say "Avantaplus 24C" or something similar. Otherwise look for the GC number, which will be in the form 47-yyy-zz or 41-yyy-zzhi, im not sure on the model atm, its only 4 years old if that helps. the flow is 1ltr per 5 seconds so approx 60ltr per minute

You maths is a bit dodgy.![]()
1 litre in 5 seconds is 12 litres per minute!
That would require a 30kW boiler to supply hot water for a bath or shower at full flow.
The 28C will give a 35C temperature rise at 11.4 litres per second. How hot the water is when it comes out of the tap will depend on the incoming cold water temperature. In the current cold weather that may not be much more than 10C to 15C, so the hot water temperature will be 45C to 50C when the tap is full on. The only way to get hotter water is to turn the tap down, as you have found, or install a higher output boiler.It's avanta plus 28c

Not rubbish, just undersized, which is the fault of the installer.ah ok so no faults, just a rubbish boiler.
Can you remember what it was , particularly how many kW?our old one was brill.
