Thanks for that. Not sure how the second pump increases the boiler output. The installation instructions said that the boiler was factory readied for 80000BTU, but to raise it to 100000BTU you had to fit a second pump. I remember the fitter being a bit confused by it too, eventually he...

Aaa, thanks for setting me straight on that. I didn't realise it applied only to cylinder type systems. The system has 17 rads which total up to 62000 BTU (18KW). The current boiler is a Baxi 133HE Plus with a second pump fitted to get it to output 100000 BTU. We mostly have showers and...

Many thanks for the helpful responses, but I thought I'd asked a simple question? I'm sure it can't be a trade secret. Does anyone remember what the rule of thumb was? If its all done different these days, whats the new rule.

When I last sized a boiler about 7 years ago I remember a post on the Forum that said you had to allow a certain Kw for the DHW. Its not exact but a rough figure, thats all I need to know. I tried Google but most of calculators now talk about a "whole house" figure where you need to enter...

Can someone remind me what the rule is for estimating the size of a combi boiler? I seem to remember a rule of thumb: total up all the rad ratings and add a bit for the hot water, but I can't remember how much to add for the hot water.

I'd like to replace a double convector 620mmx1200mm radiator with a single convector 600x1200 radiator. The radiator has a TRV at one end and a lockshield valve at the other. Can someone tell me 1. Where I can get detailed instructions as I've never replaced one before (like can I do it...

Last time it cost £220/- so its not cheap. The car itself is perfectly reliable. The problem seems to be a design flaw in the location of the sensor. Reading some of the posts in Google the wires are close to a hot part of the car so they melt and fuse, causing the sensor to fail. Nothing...

Is there a known problem with crankshaft sensor in the 2001-2006 Santa Fe? 14 months ago mine wouldn't start - just came up with the oil, engine and battery warning lights. Took it to the dealer, they couldn't find any fault codes but said that they thought it might be the crankshaft sensor...

Its true BG didn't say the contract would be invalid. What I was told was "if there is sludge build-up, its not covered by your contract so we wouldn't be able to fix it". This reminds me of 2 years ago when BG tried to get me to buy a descaler, I think it was a Combimate scale reducer...

I've got a 5 year old condensing boiler and all new pipework and rads. Fernox superconcentrate central heating protector is in the system. I've been told by BG to fit a Spriotrap Magnabooster otherwise any sludge damage to the boiler is not covered by their HomeCare agreement. I don't have...

Not really, its a well looked after older drive that I got off ebay! The DVD+r disc that it can write to is labelled "16x". The driver write speed for this disc is spec-ed as "16x". The DVD+RW disc that it doesn't write to is labelled "4x". The driver write speed for this disc is spec-ed...

I'm trying to burn some (data) DVDs using the Samsung Writemaster (SE-W164) external dvd writer. The writer is supposed to be DVD+-RW but when I put in a Imation DVD+RW disc its not being recognised. When I tried a HP DVD+r disk it writes to it fine. I'm using CdBurnerXP to do the writing...

Many thanks! I also came across a YouTube clip (http://www.youtube.com/watch?v=Y7WDVciEwdQ) from BBC Click about laptop tracking, which picks up on Prey, LoJack and other options.

Woody - I stand corrected! By the way where did you get the pricing info, I didn't spot anything when I had a (quick) look earlier. I thought I might have to go for their subscribed Pro version for more than 3 units. Are you currently using it?

Thanks, although Prey is free it has some major drawbacks - can only install on 3 laptops (we've got more than 50) - appears in Program Menu so can be easily deleted LoJack seems better as it installs in the BIOS, so will survive a hard disk reformat. The company also provide support in...

Thanks for that, although a software solution still looks interesting. The only concern would be the subscription, we'd prefer to pay a one-off cost rather than annual subscription.

Given that the laptop will be switched on at some point, can you suggest any trackers that can be fitted to a laptop to signal its whereabouts?

Is there a tracker type security device that can be put inside of laptops to track them in case of theft? Its got to be reasonably priced and easy to fit/operate as its for a school to protect their laptops in case of loss.

Thanks! Out of curiosity, how did you get to that page? I went to Dell Support, looked under Manuals and all I got was the Users Quick Ref Guide.

Does anyone know where I can get the service/maintenance manual for the Dell 745 Short Form Factor (SFF) computer? I'd like to change the hard drive, the CD drive and add some RAM. I've found the user manual but theres no maintenance advice. Couldn't find anything on the Dell Support site...
