Thanks bab...

Can somebody please help me out with identifying the Flow and Return Pipes on a Potterton Flamingo Boiler. The L/H pipe goes to the top of the cast iron heat exchanger, and the R/H pipe goes to the botton of the Heat exchanger the R/H pipe is also where the drain off cock is for the boiler...

Chris.. Thanks for the reply. To be honest I am quite conpetant at wiring etc, I really just wondered if anybody had used a wireless thermostat with a timer that they were particularly impressed with. After speaking to my supplier about controls etc I got a bit concerned about compatibility...

I have to install a new C/H system and I am having problems deciding what controls to use for it (I have been told that some controls work better with certain boilers etc). As I only normally install Combi's (and that is when I have no other work) the conventional wiring of a system is new to...

Sorry wrong discussion...

Thanks for the advice... I will opt for 5kw then I know that I am covered no matter what.

I am going to install a new open vented conventional system with a 150 litre cylinder. My needs are as follows... To run 13 Rads and 2 towel warmers....... Totals 20.185 Kw (68784 BTU). I will add 10% for expansion (Not that this is really necessary because the house is at it's full...

Thanks for your help... I couldn't find the open vented/sealed system information on the website. I wasn't being a lazy sod... just wanted some advice. :lol:

Thanks BOB for that.. I am not that worried about the size issue, I will do all my BTU calculations on that... Glazing type etc. I should have thought before I put that in my post. (Sunday night thing). I just want to know if it's worth going for the CDi as regards to the Si. Cheers for your...

I have looked... 28CDi 11.4 litres a min.... 28Si 11.6 litres a min... Doesn't seem to be much difference there... there is nearly £100 difference so I would guess that is more than .2 of a litre difference between them. I just thought someone may give me the benefit of their experience that is...

A quick question.... What is the difference between a Worcester CDi boiler and a Si boiler. What would you put in a 3 bed house with 10 rads a bathroom and a shower room. Would a 95,500 BTU be enough (roughly) or is it worth going for the big 120,000 BTU... 35 CDi, or is this just wasteful with...

Thanks Perdantic.. I will think this through and then pick your brains a little later about the stuff I don't understand. Cheers gents

Thanks for the link Kev.. I will have a read up on it and then bombard you with any questions... Cheers Mate.

Can anybody help me out with this.... I am not (As you will read from my previous posts) that clued up on the ins and outs of central heating systems, but I have been given the option of installing a new boiler into a property, they have chosen an Ideal Icos HE24 and this is where my problems...

Thanks Ollski, I will check it out.

I have already called Valiant and they only do a model suitable for caravans and boats (Whatever that means). I will try Chaff and Maury but I have found that most people just sell "Leccy" ones and not Gas. Thanks

Excellent replies Gents.. I have spoken to the customer and he is willing to go for the external vessel option, but I will try your test on the integral one first.And BradleyBear I will also try your PRV removal trick. Many Thanks all.... I will report back.

Question 1... Are these single point flueless units still allowed in a well ventilated Employees Toilet in a shop? I seem to remember from my ACS that because they are only used for a short period of time they are still allowed to be used as long as the room volume is over 5m cubed and the...

Ok Chris, thanks mate I will check. I think for ease and cost sake it is going to be better to get me to fit an external EV. If I start having to take the boiler off the wall and then strip it to replace the part, and then recommission it it is going to cost them more and to be totally honest...

Thanks Chris.. I have done that before myself, I think this customer would prefer me to replace the original one as they have this boiler located in a cupboard which they use for storage. Can I just clarify that the DHW expansion vessel having water in should just be left alone if there is no...
