I have always made it a point to fill any new combi central heating system with air prior to letting any water into it just to check those hard to get at solder joints. I have until now used one that was bought from a Car Spares Supermarket (you can guess the one) but it has now given up the...

I have looked in the CORGI direct book and they sell a book that covers the use of combustion analysers, has anybody bought this and if so is it any good (it sells at £24.99 which is a lot cheaper than the £100+ for the BS 7967) !! Stuart

I looked at a Vaillant Turbomax Plus 824E today as a part of the job that I am doing and the householder complained that sometimes the H/W temperature is only warm. After running the hot tap about 20 times i managed to get this fault to show. I felt the flow pipe of the heating and this was...

I have to go back on a job tomorrow that has got me stumped, but hopefully the regulars may give me some pointers before I go. I powerflushed a Potterton Suprima powered conventional system today and everything was fine, the symptons were a really sluggish C/H system system that would take an...

I have been asked to quote on installing 2 boilers in 2 different style properties but both on the same 1970's private estate that had warm air heating installed, my questions are abut the "Nuisance factor" of a pluming boiler. Property 1... The only place to install the boiler in this 1...

Maybe a stupid question but... When replacing a Ravenheat Thermocouple with an attached sensor on the flow pipe, does this just attach to the surface of the pipe or is a boiler airlock job.

OK.... The story so far... " Along time ago in a galaxy far far away" (Not sure if Orpington in Kent counts as a different Galaxy but I'm sure it is not of this world.. MMmmm) I get asked by a friend of mine to service his back boiler because "It has been over a year since it's last Service"...

What is the cheapest way to run a Hot Water Cylinder ? I can't remember the answer to this question !!! If a household has a domestic hot water cylinder that complies with BS1566 and a cylinder stat (Guess who has just done the Energy Efficiency Course) Less said about that waste of time the...

I have been asked to repair a Ariston Micro combi MFFI for a letting agent I do a load of work for (I try to avoid Aristons like the plague) I have tried working my way round the boiler with my multi meter but have drawn a blank. I have bundles of H/W and the boiler chugs along quite merrily...

________________________ lynda, moderator you asked the same question here although hopefully the plumbers will see this and reply there :wink:

I am finally being persuaded to look into buying a Gas Analyser for my boiler commissions and repairs etc. I have looked through the CORGI Direct book and they have a list of about 6 different machines. I have pretty much narrowed it down to 2 machines which are.. 1... Telegan Anton Sprint 2000...

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...

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...

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...

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...

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...

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...

Hello Gents... I have to replace the expansion vessel on a Ideal Response 120 which should not be to much of a problem and while I am about it I will replace the PRV as well. My problem is this.. the underside of the boiler is pretty inaccessible and by sqeezing my head under it I can see the...

I am thinking of investing in an Electric Pipe Freezer, at the moment I use a Polar Ice can freezing kit but to be honest I find myself having heart failure every time I use it in case it lets by. I have been thinking about getting an electric one (Possibly a Freezemaster 280D) about £700 from...

Hello Gents... I have to install a new boiler for a conventional system and to be honest I am at a loss as to which one to recommend to my customer. I have installed a few Non Condensing Combi Boilers and have tended to stick with Worc/Bosch and Baxi but this is going to be my first Condensing...
