Apologies, suppose it makes sense that the same people frequent many forums - was just trying to spread opinion. I’ll close this one. Other here: https://communities.theiet.org/discussions/viewtopic/1037/26470 though not quite “answered” yet.

Hi all, I need to replace the old fuse box in the garage with a CU and at the same time install a load balancing a fast charge outlet for electric vehicle. Current installation has a sub panel in the house (40A) with type B MCBs: 20A for kitchen sockets and 32A for the garage supply. Main board...

Thanks guys. In the bin it goes (or eBay at least!)

Hello, I'm about to have my boiler/ hot water tank replaced and converted to un-vented, which will leave the hot and cold water balanced at 3.5bar. I have two showers - one with a pump - easy: just remove the pump - and a Mira Vigour thermostatic power shower. My question is please: what should...

Sorry, wrong word - I meant heat exchanger not manifold. Filter was located right next to the pump, accessed from below, and rather difficult to remove. It was long and finger-like black plastic and had narrow slotts arround it; the top most of which were filled in with black crispy residue...

Ok. Filter cleared - yes fairly clogged with black crispy bits. Pump certainly seems to be running. Boiler fired up and ran for a few seconds before stopping again this time with an F14 code - another overheat code. That one seems to be recoverable as after a short time it started up again...

Thanks very much for your swift replies. I see from the schematic that there is a CH filter on the 30SI; I'll drain it down and fish out the filter tonight. Is there any specific procedure for cleaning it, please?

Hello, I've a Glow worm 30SI which has failed with an F5 error code. On searching, I've found that the overheat sensor can be re-set, which I've done. This allowed the boiler to fire up briefly, but then the sensor tripped again. Am I right is suspecting a failure in the pump in this case...

And when you've got a daughter and two sons too.... :shock: Might have to tink about a bigger tank too! Thanks for all your advice :)

Sure, but I don't shower in water at 60C! However, am I right in thinking that the event is about 0.1 bar, so does that mean a 2.5 bar can deliver 200 to 400 litres per minute? Surely not! :shock:

That's an interesting point, thanks. If I go for a 2.5bar what sort of quantity of water will it get through? I've got 117litre hot water tank, and it will probably be being used at the same time as the mira event in the bathroom!

OK, thanks for your replies. Could you suggest what pressure I would need for an 8" deluge, and what pump would you recommend, please?

I'm installing a wet-room style en suit shower in the main bedroom. I've got a Mira Event over the bath in the bathroom and whilst that works really well, I'd like to have a deluge style in the en suit. My question - do I really need a 3 bar pump to supply an 8" deluge (as Salamander tells me)...

OK; so I've got the plumbing done right, now for the electrics - Hope I'm not making any fundamental errors here: What I'm planning is to take the towel heater (150w) to a simple felx plate on the wall (its in zone 2 - 1.1m from the bath) where I'll take it to a double cut fused neon switch...

Fair points Taylortwocities, especially re. the air. Looks like I'll just have to do it properly then won't I!
