how does a combi work?
Like a turbo

what is the difference between a cylinder and a combi?
One's round

what is the difference between an indirect cylinder and a direct one?
One's an accusation - the other's a rolling pin

why would you choose a direct over an indirect?
Gets it over and done with

Probably doesn't help much but I've been to the dentist, got toothache and need cheering up

Hi.
1. insert a short bit of copper pipe into a length of hose, connect to cold tap hold copper pipe over gas ring and open end over sink. Turn on tap a little and light gas. Get her to feel for temp change at discharge end, turn up flow from tap water will get cooler just like a combi. Then the washing up
2. Us the same bit of copper warm up over gas and plunge in glass of cold water, note the increase in temp.
3. Now days direct may be used where the only form of fuel is electricity. Heated by immersion heater element (about now get her to put the kettle on that's direct) Put hose on hot tap and coil it to fit in a kettle full of cold water, That indirect. That the C&G passed. corgi next. Good Luck

Ok, I would never say this to my better half but just can't resist this and I know its sexist and not very PC, but I would explain to her that women are as good at driving cars as they are at understanding plumbing!

Now, I've just been whacked, I didn't see her standing behind me............... I'm in for a good evening!
