hi, citygas is not costly. basically all gas products are control products, if either one overcharges, i think ppl in SG will go on strike either physically or online... ;-D
the best thing abt using citygas is that you dun hv to worry abt gas running low. its there all the time.
a 25L storage heater for a 5rm flat is more than sufficient. eg. a person drinks 3l of water per day, this will last for 1 week. and storage heater purpose is to store water and heat it up for usage, it will be replenish frequently so it should be more than enough for use for whole household. and also pls do reminded to save our earth by using a suitable tank size as it will mean saving energy needed to heat up a bigger tank of water. generally, a 25L tank will be sufficient for a 5rm flat. if yours is a private landed house, then its best to check with your plumber or renovation contractor and not your ID. these ppl are more experience and able to do a correct sizing/calculations. if there are still further doubt, do contact the mfgr office directly for clarifications.

water from storage heater can be use for washing areas instead of using for bathing only. the only initial cost is to install hot and cold water piping all around the whole which your plumber guy will be able to estimate a cost for it.
whether it should be horizontal or vertical, it depend on the space that is available at your hm.
installation of heater itself is generally charge at S$80. copper piping depend on the mkt rate and the length that is require to run to the designated point.
citygas free instant heater runs on gas and must be install at kitchen or expose area. enclosed area is not allowed due to safety reasons.
and of coz, running on gas is cheaper than electricity.
