Hi sam07 thanks for your reply i tot of using the electic storage type like joven or ariston, however id said have to add installation charges per point come up to 600-700 plus excl the price of the heater ($200+)So total have to spend 800-900 to install the storage heater type, even though have all the hot/cold water pipings in our new flat then went to city gas and heard that they are giving out FREE gas water heaters, but have to open a city gas account...As i am using a vitroceramic hob(electric) hob, thus a bit silly to use gas for heater right? PROs of gas is that : it is free and water heating is instantaneous, as long as no one is bathing using hot water, the kitchen tap or other points can have hot water as well. CONs is that my parents told me sometimes gas might leak and might have gas poisonning! i so scared cos might be alone at home sometimes and sound suicidal! PROs of electric is that it can supply to all water points, CONs is that the cost of installation is high and heating up the water takes time like 10-15 mins. or do u suggest those individual electric type attached to bathroom like 707 brands ones... Please help and advise
