questions
A question is an utterance which typically functions as a request for information, which is expected to be provided in the form of an answer. Questions can thus be understood as a kind of illocutionary act in the field of pragmatics or as special kinds of propositions in frameworks of formal semantics such as alternative semantics or inquisitive semantics. Questions are often conflated with interrogatives, which are the grammatical forms typically used to achieve them. Rhetorical questions, for example, are interrogative in form but may not be considered true questions as they are not expected to be answered.

On the 'modular pipework' section the 4 pipes going to fan coil units, two are just flow and return from a heat source like a boiler and are the other 2 from a chiller so in summer they can provide cool air, is that right?

I'm repair engineer and I've never really done any full installation work before.
I need to put a full central heating system in my dad's house he's buying. Currently there's just a gas meter and electric heaters, so it really is a blank canvass! My dad wants the gas pipe running in the wall...

Possible stupid newbie question coming up!
Q1. I've always wondered... WHY do Central Heating Pumps have such huge couplings on them?
I doubt many homes use pipes bigger than 22mm - but the couplings on all the pumps I've ever seen have about 40mm threads.
My guess is so you can change the...

Hi all
I want to keep my bills down. Hardly ever use central heating. The installers set my hot water temp to around 53 degrees and the radiator heat to 60.
Would it save money if i reduced it from 60 to 50 or even 40? (once i figure out how!)
Also, if say the rad heat is set to 60 degrees and...

Hi All,
I've moved into a new place and I'm having some trouble with the thermostatic shower, which is warm at best, despite a piping hot inlet.
I've taken it to bits, given it a descale with some vinegar and lubricated the seals. This did the trick for 10 mins or so, but it then went back to...
