As stated about the Worcester Greenstar Condensing Combi -
"Key features of the Greenstar include the pre-heated domestic hot water
heat exchanger. After the store has reached temperature hot water is
delivered instantly to the outlet being operated. The temperature and
frequency of the recharge of the store may be pre-set. Modulating central
heating and domestic hot water outputs, combined with separate consumer
controls, also mean that comfortable temperature levels for both can be set
independently of each other."
