Low hot water pressure

[Jason brad]

I've had a new Firebird combi oil boiler fitted and the hot water pressure is low( in fact it's terrible)..the cold water pressure is good and I can't find any leaks and loose no pressure. Please help. Thanks alot

The hot water pressure is terrible?, do you mean the hot flow rate is very poor but the flow rate is OK but too cold if a hot tap is opened fully?
What is the Firebird power output.

The flow rate is always low but the water always stays hot. Will get bk to you on power output.. many thanks

Not been in touch with them yet.just need to no if it's a problem or if that's how it should be.

Should be the same as the mains pressure

20kw should give a hot tap temperature of 40C at a flow rate of 14LPM or 7LPM at 60C, can you just open a hot tap fully and see how long it takes to fill a 2 litre container or any sized container and compare this with the time taken to fill the same container from a cold tap.
