We have just completed a job in the Chislehurst area where the customer had very low water flow rates and only two bar mains pressure so a combi boiler would not give the customer the necessary requirements needed and he wanted to do away with the storage/expansion tanks to create more storage as the property had no loft so the solution was to install this heat bank/cylinder which is mains fed without being pressurised and no drain /discharge pipe required giving better flow rates than the normal tank fed system it can be installed as direct or indirect using the existing boiler system.
