Hi
I have a Firebird external oil combi.
What I want to do is limit the flow of the DHW because when we run a bath the water comes out too fast and starts to cool down. Obviously I could turn the tap off a bit to limit the flow, but you end up constantly adjusting the tap to get a decent temp/flow combination.
However, what I want to do is get some kind of flow restrictor to limit the flow coming off the boiler to say 12 litres/min. Preferably an adjustable one so I can tweak it. That way the boiler will always give DHW at a consistent temp.
OR ideally, something that slows down the flow rate from the boiler to maintain a set temp.
Do these things exist? I can't seem to find anything on google but I don't really know what to search for except 'flow regulator' but that doesn't turn up much.
I know you can get thermostatic mixing valves as I have one on my shower.
I have got a spare PRV so could limit the pressure but I'm not sure on the relationship between pressure and flow.
FYI, my mains water pressure is between 5-6 bar.
Thanks,
Matt
