Combination Storage Boilers are particularly suitable for larger properties with possibly two bathrooms.  This type of Combination Boiler has a small storage vessel within the boiler which allows a flow rate of up to 18 litres a minute to flow to the hot water taps.  This allows two taps to be used at the same time without an unacceptable drop in performance.  The main advantage of all Combination Boilers is that they provide continuous hot water all 24hours a day without the need for reheating.
