New boilers with permanent lives

[kevindgas]

The Baxi Solo HE range of conventional boilers have no permanant live or pump live. Just Live neutral and earth, so will replace all boilers on a fully pump system with no additional wiring needed.

They were useless a few years back but are a decent boiler now that they have ironed the probs out. Ive installed quite a few and not been back to any faults.

interesting fact but the thread is about perm live boilers and certain person who likes to think he know everythingabout everything yet doesn't and won't prove he is actually a professionally qualified person

the thread has then discussed the merits of a means of electrical isolation at the boiler and the availability of a suitable switch

Stick around you'll soon work out who when he pops up out of his hole

A 4 pole switch you mean. I always have that done where appropriate. Many W-B boilers need the power going through the boiler, which can complicate wiring.

whats complicated about 4 wires

What didn't you understand about.."Many W-B boilers need the power going through the boiler, which can complicate wiring."?

As you don't understand, the mains has to go through the boilers control box and the to all the other controls on the system. Many have the mains into a wiring centre and the permanent live to the boiler from there. With some Greenstars tat is not the case.

actually most of us are educated and have the certificates to prove it

where are yours?

 

[namsag]

I would not class an ACS certificate as that. AND no im not BB

Ok, so I install a boiler that requires "mains to go through the boilers control box and the to all the other controls on the system", WB, Vailant, Vokera, Ideal etc etc. In this case why the hell would I want to fit a 4 Pole isolator!, when a 2 pole will do the job perfectly.

because there are 2 lives (1 perm and 1 switched) + neutral coming from wiring center and the idea is to have local isolation at the boiler thats why I do it with a Crabtree 3 pole (Fan type) switch

I think there may be some confusion! Instead of messing about with tp isolators why not install fused spur beside boiler? Spur > boiler > wiring centre? I know sometimes boiler swaps/existing cables etc would mean you'd need to leave spur in airing cup

 

[kevindgas]

yes that is an option but most of the stuff we find is already there (boiler change rather than new install)

Give it time

BB stated "the mains has to go through the boilers control box and the to all the other controls on the system" therefore if you isolate the mains supply to the appliance it will shut it all down inc SWL. My question was, in this case why use anything other than a 2 pole isolator.
