Pretty straight forward question really, I'm looking at flushing my system out while I go away for a month. Would F3 be ok to be left in the system for that time? Would the results be better or would it degrade over that period? Cheers!

Cheers, most appreciated

Hi, Im looking at installing a couple of extra rads in my house (about 5000btu each) The central heating system is a drop system (upstairs ring main, then 3 drops to the downstairs rads) Question is, I was looking at tying into the upstairs ring and then doing a fourth drop for the two extra...

Cheers Mick Yes the 210l is the largest I can go for in the space. I could go for the 250l Ariston, but then I cant make full use of the Vaillant ebus NTC sensor. I suppose where i am used to a conventional open system i cant get my head around the water heating up in only 20 mins!

I would really appreciate some advice from anyone who could offer some help with the following - I am after changing my open vent system with a unvented cylinder etc. Problem is I'm after a 250l but only have room (height) for a 210l. Has anyone experiance with a 210l (for reheat times and...

Bloody Welsh! Thats where all our money goes :wink:

Cheers Crockett, if I did go for the Primo do you know if I would still get all the energy saving benefits from the Vaillant? And is the Primo any good?

Hi guys, I wonder if anyone could offer advice.... I'm getting a new boiler (Vaillant 630 system) and with it a 250l indirect cylinder. The problem is due to storage, the cylinder needs to be under 1600mm in height. I was looking at the Unistor, as I was impressed with the obvious compatibility...

If I relace the MCB's and keep the original RCD the original busbar will not fit. Do you mean get 2 new MCB's and a new proprietery busbar, to make it work. Sorry if I'm being thick!

Hi, dont think I've managed to add the images, but the URL to some pis is: http://www.bcagroup.co.uk/products/consumer.shtml My MCB is the 3rd pic down. The CU is the bottom one. Many thanks in advance

Just looked up '721.43.1'. And is does mention DP's are required. Something to do with polarity reversal Seeing as this is the case, if I replaced my crap F&S DP MCB's with a decent brand, which i can get hold of, the buzz bar will not connect. Would it be safe and sane to use wire instead of...

'Think it comes under 721.43.1' Is that a part number!! :D

I've spent the last two days trying to get hold of replacement MCB's for the soddin' thing. They are F&S twin pole Type C MCB's one 15A and one 6A. As I may have mentioned I've looked into these a bit and the general consensus seems to be they are crap! My next question is would it be...

Wingcoax - supply comes from an external source which also has an RCD/MCB. This does not trip - In my caravan there is an RCD and 2 MCB's one MCB shows 240v when i tested it, the other one shows 0v. Both MCB's where switched up. After I 'fiddled' with the MCB it showed 260v (I don't know if...

Hi Guys, just wondering if anyone can offer advice about a problem I'm having with my caravans electrics. The MCB seems to be fooked - its a F&S 10A MCB, twin pole. When I've tested it there is no current at all coming out of it when its switched on. Its been working fine then all of a sudden...

Fairly big 4 bed detached with 2 bathrooms, occupied by me the mrs and 2 teenage girls!

So guys do you reckon my money will be well spent, with plenty of flow for a decent shower?!!

Thaks for all your replies guys, and yes I was after reassurance. I'll sleep better tonight! One last question (promise!) will the flow really increase from 22l/min to 30l/min when the 15mm t is removed and the system is fed by the 22mm pipe?

the rads are anything from 5 to 15 years old, all in good nick with trv's allready fitted. The pipe is all copper 15mm. No sludge problems to speak off but inhibator has not been topped up. The reason I'm concerned is cause I'm spending a hell of a lot of money (for me anyway) and any boiler...

Any help would be greatly appreciated chaps, I really don't want to fork out all this dosh unless I'm certain my plumber is telling me the right stuff
