Logic 30 combi - massive hot water delay

[Allan Reid]

Hi,

I just moved into a rented property and want to make sure this isnt an issue with settings before i report it to my landlord.

The boiler fires up instantly when i change the thermostat for the heating.

There can be long delays before hot water flows - this morning it took 20 minutes for luke warm water to be delivered via the shower. Seemed to take this length of time for the P display to appear on the boiler for preheat function.

Frequently we get hot water via the tap that then goes cold for a few minutes before heating again. This repeats in a cycle.

When filling the bath, the water never gets very hot and we never need to run the cold tap to balance the temperature.

Cold water flow is fine on all taps.

Any ideas of what to check as a novice?

Thanks,

Allan

Best bet is to get the landlord to arrange for someone to come and look at the boiler.
