Hot water problems with Baxi Baham 100

[Munster]

We have a Baxi Bahama 100 in the new house we have just moved into. It heats the rads no problem. The issue we have is with the hot water.

If we want a bath we have to run the tap first at high pressure to ignite the boiler then at a very low pressure to ensure that hot water comes out. We can't run it at a sensible pressure. It takes an eternity to run a bath as we have to keep the pressure of the hot tap so low.

Is this a common fault? Someone told me that this happened with all combi's but I never had this problem im my last house. The boiler is in the same room as the bath so it doesn't have to tr4avel far.

Replace the DHW flow switch also sounds like the plate heat ex needs cleaning/replacing!

Thanks for your replies.

When we have finished renovating the rest of the house. I'll call in the specialists or is this a job that a keen DIY'er can do themsleves?
