Anyone know where I can buy one of these? - Thanks. Kind Regards, Shane Cook.

Is there a limit to the number of radiators you can have in a system? Can I run 9 rads from a 15mm pipe, if everything else in the house is 15m or microbore? I read in one of the B&Q leaflets you should only use 3 rads from 15m. I already have a bunch of 15m pipework to one rad, but to replace...

I've just noticed the Heatrae Megaflo HE CL 300 L HE will cost me £1,021, and it's Titan equivilant just £586. So why twice the price? Has anyone installed the Titan one? Kind Regards, Shane Cook.

Spark, I've found a diagram here: http://www.discountedheating.co.uk/shop/acatalog/Online_Catalogue_Unvented_Mains_Pressure_Hot_Water_Cylinders_77.html The indirect system uses a coil by the look of things. I always seem to be quoted around the same price. Anyone suggest a better place...

I want to install, or have installed, a Heatrae Megaflo HE, but I don't understand what the difference between a direct and indirect system is. The direct one is about £200 quid cheaper, so this seems like a good bet, but how do I know which one I need? I have an oil burning boiler on the...

I'm looking for a programmer that can control three heating zones plus hot water, ie four zones. Are there any such products on the market? I've managed to find the "Horstmann H37 Centaur Plus" which does three zones, but none that do four. Any suggestions? Kind Regards, Shane Cook.

I've heard that thermostatic radiator values break and need replacing over time. Is this true? Are some brands better than others? If so, which ones are the most reliable? Thanks. Kind Regards, Shane Cook.

Is polystyrene not a fire hazard? I'm asking because we have a similar problem. The stuff you're talking about comes in big white sheets? Kind Regards, Shane Cook.

I found installing the reflective and insulated panels you can get from B&Q immediately beind the radiator made quite a bit of difference to the room temperature. All our radiators are on external walls, which are old cavity ones with no insulation. I was a bit sceptical, but they certainly...

Well, the grant is £125 providing you used an approved installer, rather than install it yourself. The improved installer charges £320, of which you get £125 grant, so it still costs you £195. This is just money for the boys, IMHO. Come on it's not hard to roll out a few rolls of insulation in...

I was wondering how you go about insulating floors in Victorian houses. Under the floor, there is a dwarf wall, which sits on earth. On top of the wall sit untreated rafters, on top of which sits sheets of compressed wood bits. I know these type of floors must have air flow via the air bricks to...

I was wondering if somewhere like B&Q was actually a good place to be buying insulation? I need a reasonably large amount (£250 or so) of loft insulation and also the pipe insulation for our new central heating. Loft insulation is rather bulky so rather than make half a dozen trips in the car, I...

Breezer, do you know what model this is? Thanks. Kind Regards, Shane Cook.

I have a number of lights I'd like to switch on to 20% during the evening/night, and 100% when a PIR activation takes place. I'd like to have a number of PIRs, any of which trigger all lights. I can do this part by connecting the PIRs in parrallel, and the load in series, so any PIR will...

The program doesn't support emailing the photo to an internet server, or even opening and closing a dial up link. It doesn't support multiple cameras either. However, for $20, it looks like you get a pretty good program. Are there any betters one on the market? Kind Regards, Shane Cook.

"The pressure in the system has no direct effect on the water temperature" - then why pressurize the system? Do they not do this to increase the boiling point of the water, thus allowing you to have a higher temperature of the radiators than it would otherwise be? Kind Regards, Shane Cook.

I have a Velux window, in our new house, with a nice woodern window frame. However, the previous owners have painted over the woodern part (the bit next to the glass) with some horrid white paint to match the rest of the room. Is there anything I can do to remove this paint from the woodern...

il78, That sort of assumes you have a permanent connection to the internet. I'm after something that would startup and shut down a dial up connection. However, the IP addressable multiplexer sounds interesting. Do you have a link to it? Thanks. Kind Regards, Shane Cook.

Cheers Ben. Please send it to [email protected] - Thanks!

Being a bit of a computer junkie, I'd like to monitor my house using a number of fixed cameras, connected to a PC, and have the PC monitor the camera for movement. When movement is detected, I want to start capturing video or a series of photos and have the PC email then to me, or upload them...
