How do you have yours

Don't they "peg out" quickly though compared to a regular boiler?

Not in my experience, though I've not had one for more than about five years.

This isn't quite a fair comparison, because of constantly improving technology, but I've had two conventional boilers peg-out on me in my lifetime, but no combis.

The main advantage to a combi is the cost saving if you're an "irregular" user of hot water. You only heat what you need, when you need it, rather than heating up a whole tank-full, which you then leave to get cold again for the day, while you're out.

In the year we changed, our gas bill went from over £400 to under £150. We paid for the new boiler in two years of savings.

Is there anything wrong with boiling water for tea in a kettle filled with water from a hot tap?

Apparently fresh, cold water straight from the tap is best as it contains more dissolved oxygen which is released when the water boils, and reacts with the tea to bring a fuller flavour (or somet). It's why they say you should never use water that's been boiled already or has been standing for a while.

I'd also agree with Gavin that 'coffee boiled is coffee spoiled'.

Interesting - I only ask because someone I know always brews tea that way and it irritates the hell out of me.
