My 16 year old Turbomax is great with hot water, especially after I cleaned out the plate hex with some acid few years ago. I turn the water temp control on boiler down a bit in summer, and up a bit in winter.
If your boiler has a hot water temp control (some don't eg. older Worcesters), have you turned it up?
yes mate it's made a difference, might give my heat exchanger a clear out! Im a "wet" plumber so don't do boilers at work so it will be a nice bit of experience for me👍👍👍 Check if the plate HE is OK. Easy to do, the HW temperature coming out the Combi should roughly be the same as the Return water coming out the Plate. |

Easy to do, the HW temperature coming out the Combi should roughly be the same as the Return water coming out the Plate. I've turned the boiler up to full and it says 62 Deg on display, put my hand on hot water pipe as it leaves the boiler and it's hot but at taps it's about 30 deg. The problem seems intermittent, yesterday water was piping hot! Any thoughts guys🥴 |

just a thought, is there a mixer tap or shower valve somewhere thats passing internally so the cold is mixing with the hot, ?

Like it tom👍 I'll isolate each one and see what results I get. I seem to notice the problem more at night when mains pressure goes up👍

Depending on the boiler, getting the plate hex in and out can be a doddle or sometimes a bit tricky. But that's the only difficult bit. Get yourself a bottle of Spirits Of Salts and pour in both sides of plate and leave for 10 mins. Flush out and job's a good 'un. Precautions are usual for dealing with acid - eyewear, do it outside and don't breathe the fumes.
How would it go if you poured one shot in both sides? That shit is lethal Some people say clean in with brick acid hence my question about one shot Hey Rocketman, Brick acid and spirit of salts are both hydrochloric acid. One shot etc is sulphuric acid. Ive always used brick acid, never heard of using one shot, and it would stink! Be careful! |
