We have had a combi for about 5 years and have it serviced regulary .It was serviced about six weeks ago but it seems to be a lot longer for the hot water to run through ,even though the boiler is situated in the kitchen.Earlier on today Id filled a 4 pint jug eight timrs before it was hot enough to wash the dishes.Iam very careful about wasting water and I put it into watering cans to water the garden but it is getting to be quite tedious.Has anybody got any idea suggestions ,please?I would be greatful for any replies .Thankyou.
I don't know how it was set up before the service, but Combis usually have a storage vessel (10 litres or so). This gives you a certain amount of "instant" HW. The boiler does need to be left switched on in HW mode though or the stored water will cool down.
