Hi - I appreciate there are wireless programmable roomstats which seem to be mainly used with combis and I've also seen previous threads where this can be used together with a simple timer for HW control with normal boilers and 2 MVs. But can anyone tell me if there is now a wireless...

Thanks for suggestion - never used one even though I'm fond of gadgets. But maybe still a problem in older houses where picture rails and skirting boards tend to be a bit more irregular??

Thanks D_Hailsham, you're one of my heroes on this forum! And I can easily assess your calibre Agile - it's of the highest order! Looking at various problems going back several years, I'm very impressed by the good sound advice both of you have freely given. In my profession, expertise was...

In the past couple of weeks I've had quotes from several plumbers. The common feature is that all have complained about being too busy!! I'd say it was a blessing! - it's great to be in demand and even better if you know you're going to do a good job and the customer will be happy. And the pay...

When I'm trimming wallpaper I mark the paper along picture rail/skirting with the back-edge of a knife then (becos of fading eyesight) mark the crease with a soft pencil. Despite careful cutting along the line, I sometimes end up with the wallpaper 1 or 2mm short. I know the simple solution...

Thanks for that, it's the article I looked at earlier. A very good site for plumbing and many other things. Got it in my Favourites folder with many others and haven't looked at it for some time.

I know how to balance a system (I think) but I'd have to use a rad thermometer. Hopefully the plumber will check anyway. I've seen the relevant info in FAQ section (VIA LINKS in various answers) but (and I'm sorry about this) how do I quickly get to the FAQ section?? I've got the "Wiki" and...

Hi - thanks for that, I'll check out the FAQS. I'm sure on balance (pun intended), it's best to balance the system even with TRVs. It's just I thought I'd seen elsewhere on this forum someone suggest the lockshields were just left fully open with TRVs.

Hi - thanks Happyplumber for quick reply. I did realise RF was wireless and would generally prefer hard-wires, And I appreciate plumber is using it for his (and my) convenience as it would be quite difficult and messy to route additional cables. Although RF roomstat will probably stay put, it...

Hi (especially D_Hailsham) - I was looking at a previous response in which it was said it is important to balance the system for TRVs to work properly. Can balancing in effect be achieved by simply adjusting the TRVs in any rooms that don't reach desired temperature? Setting 5 seems to be the...

I'm having my CH/HW upgraded soon (at last!!!) with a new boiler and S-plan system, using Honeywell controls and valves. The plumber suggests using the Honeywell RF analogue roomstat (Y6630D1007) but I would prefer the digital model (DT92E1000) mainly because it's easier to see (old age is a...

Thanks for that BazBee. Not sure when this work was done but certainly the bath is fairly modern - maybe someone who couldn't be bothered to update the pipework at the same time? I could understand if it was when copper was less commonly used - but what a pain to go from iron to copper to...

Thanks bertrum09 and kevplumb - was beginning to think I'd used up all my goodwill on this site with my silly questions!! It's a 1930s semi-detached as I said. Mainly threaded iron inside the house but does dive off here and there in copper. The feed to bath cold tap is especially unusual and...

Hi again!! - I seem to have an internal mish-mash of pipe materials (which I'd love to rationalise) and I'm wondering if it's par for the course in a "part-modernised" 1930s semi such as mine (outer London area)?? I'm not sure if the incoming mains is lead, would this typically be the...

The objective was to satisfy my curiosity!! For the past week or so, becos of a CH prob, I've been using the immersion for HW. It seemed to produce a fair quantity of v. hot water in about 30 minutes but I wasn't sure how much. My calculation was similar to TicklyT - and you guys also said...

Hi - not sure if my schoolboy physics is letting me down? If you input, say, 3kw or approx. 10,000 Btu into a 30 gallon HW cylinder, how long would it take to heat the ENTIRE contents to recommended temperature? I make it close on 3 hours?? - although I know in practice you probably...

What did this tell you that you hadn't done before??

I agree bengasman - no substitute for empirical evidence ie based on experience. I'm sure a good plumber can tell almost by eye what's needed by looking at the house and lifestyle/requirements of occupants. Me and the missus are of Inuit descent so anything above 60F and we start stripping off -...

Cream colour carpets Agile?? We've got bits of lino and old newspapers throughout!! I did mean a few hundred including price of new TRV (need about 6).

Thanks Agile. Main task is a new boiler and upgrading controls. I'm quite happy to keep exisiting rads (provided they don't leak with all the new power surging thru them!). Just thought, for completeness, might be a good time to change TRVs - would obviously be cheaper whilst guys are on...
