How does combi boiler hot water work?

Combi boilers provide a “combination” of instantaneous hot water and effective central heating. Combi boilers work by signalling a sensor once you’ve requested hot water which tells the boiler to burn fuel (whether gas, electric or oil). The heat exchanger then gets hot enough to heat the water when it flows over it.

Do you get instant hot water with a combi boiler?
