There's more than one type of drain off valve, but most have a rubber washer, at the end of the square headed brass plug that you turn to open the valve. What commonly happens is that the rubber sticks in place, so even though you've undone the plug, no water comes out. If you remove the plug...

You find the 'Randall' site by googling 'Danfoss' or 'Danfoss Randall'

Howsabout prolixity instead of longwindedness? :)

You haven't been caught out by a froststat have you? e.g. boiler in an unheated outhouse, so could freeze.

Has it always been like this?

Sure the pump's still working? Can't see the relevance of feed/expansion/bleed valve right now. Air in the rads?

Exactly so. Different aspect, wind chill factor, slight dampness due to rain or building defect, non 'standard' construction, so the U values aren't right. It all makes a difference, then we can start on what makes you feel comfortable - how warm were you to start with, what are you wearing, and...

Adding Fernox boiler silencer can help a lot. About £25-£30. Adjusting the gas pressure requires the right tools and information and is to be done by a 'competent person', so you'd better call the service engineer back. if you do get a new boiler get several quotes as BG usually top money.

Pump still working?

It's ok if you are sure you maintain the 'hooked over the cistern' vent, unobstructed all the way from the boiler and no reverse falls, i.e. rises all the way, not necessarily vertical all the way. Plastics not within one metre of the boiler, say most boiler makers, so check installation book if...

Exactly so

The design of a waste sytem is often incorrect, although information is available to avoid this sort of problem. There are maximum lengths for waste pipes and recommended falls. Not following the rules can lead to traps being emptied, allowing drainy smell into the room. So - without having...

Well if you stood for the lib dems, the leader might stand you a drink (or three!).

Every time you introduce new water, you introduce a little air, because it is dissolve in the water. When you heat the water, the air comes out . That's why you see bubbles rising in a saucepan or kettle, well before it boils. Has the system got enough inhibitor to prevent corrosion? You can...

Think of it this way:- All the heat you put into a building leaks out. The more you put in, the higher the bill. If you had electric fires, would you leave them on in rooms you don't use?

I suppose that if you haven't the time/inclination to do it the long way, and are in a hurry, then you could take the average result from the calculators/charts on the web (excluding any results which are wildly different). Obviously if it's too small you'll be unhappy, whereas if it's too big...

Hate to be miserable, but this is a serious problem. It did kill someone in Cornwall and his/her partner was hospitalised. The regs are now changed so that new immersion heaters now have an overheat stat that doesn't automatically reset itself, as well as the usual adjustable thermostat. New...

Well maybe it's getting up to temp, so stopping before it gets to the next level up, being 'overheat light comes on'. Go on, down the shop - get a new pump and stick it in!!

With a hired pipe freezing kit or, if you're brave, buy an aerosol pipe freezing kit. When those first couple of drips start coming through the ice plug, you know you've had it!!!!

It depends on the pipework. If gravity hot water with pumped heating, then you'll still get hot water if the pump stops. If both hot water & c.h. are pumped circuits and the pump is stopped, then the boiler will start, but quickly go out because it overheats. You might get a very little warm...
