Thanks Daveydub for all your help, I will order my new programmer tomorrow and start saving money.

Thanks for everybody's help and advice, not really sure yet if I have a gravity or pumped system before I go and purchase the new programmer. I will try and track down the installer of the boiler and ask him the question, cheers.

Thanks Daveydub, so what you are saying is that I will be able to go ahead and install the ST9400c and I will be able to independently have HW and CH at my mercy, thanks for your advice its very much appreciated.

Here we have my programmer, this morning my heating was on for an hour to take chill off house but at the same time the water will come on unless you either physically get up and overide it or slide the switch to off the night before but then you need to remember to switch it back for hot water...

Cheers Daveydub, I am at work on night shift so will post a pic of my programmer tomorrow, thanks for the info it's very much appreciated.

Hope this pic is clear enough, I cannot see where possibly there could be a pump. Thanks for your help.

Got a reply from email to Honeywell to say that the programmers are compatible but since found out from them that I need to have a pumped system and not gravity fed, now totally bamboozled as I don't have a clue what my system is. Can anyone help, much appreciated.

Yip 45yearsagasman and thanks for your reply, got 2 of them in my hot water cylinder cupboard, one is marked HW in black marker and the other one is marked RADS. Am I any closer to getting my question asked.

Thanks denso13 for the reply, what I have is a Worcester Bosch system gas fired condensing boiler with a hot water cylinder tank and a cold water tank in my loft, any help much appreciated.

Anyone

..... upgraded Honeywell ST9400C. I have had the old programmer for about 4 years and it is not energy efficient for me considering the price of gas these days, the programmer will turn on my heating but at the same time the water is also on unless you physically turn of at the programmer...

Hope you can help me with the photo, cheers.

Will post a pic tomorrow, thanks.

What size should I order, do I measure the width of the copper pipe going into my old TRV's. And what are the valves called on the opposite side of the rad. Sorry but not a plumber.

Had my old central heating programer for a few years now and when heating is on the hot water is on, is it possible to buy a programer that heats hot water and central heating independantly.

Getting a new central heating towel rad fitted and been told it needs a TRV is this correct, websites that are selling the rads link me to a page that's selling me chrome radiator valves not TRV's. Any help please.

Looking to retrofit the DT20 timer in my Worcester Bosch System boiler, can the integtral diverter valve be fitted once the boiler has been installed. The reason I am asking is that I have a diverter valve fitted next to my hot water tank, any help would be much appreciated.

Can I not just cut the pipe with a hacksaw, is it possible to buy the inserts singly.

I need to shorten my cold water feed it is on a plastic 15mm pipe what do I need to shorten it. Cheers.

Thanks guys when I get my new stat I will post pictures of both wiring setups. Cheers the noo Willie
