I'd appreciate some input from Houzz users regarding choices when I replace my hot water system in the next twelve months. I currently have an elderly 120L electric off peak storage tank in a laundry alcove, which I will need to replace soon. I would like to use the space (in a laundry alcove off the kitchen) to rehouse the refrigerator when I remodel the kitchen. There is no piped gas in our town so I'd have to use bottles. I'm trying to find out the relative running costs and advantages/disadvantages of solar vs instantaneous gas. I'm also tossing up whether to install a gas cooktop in the new kitchen vs an induction model. If I convert to gas for the hot water, a gas cooktop would then make more sense. There would be gasfitting costs on top of the plumbing costs, obviously. The existing copper pipes are in the roof cavity so installation of a solar tank on the roof would be relatively easy in terms of marrying the old pipes to the new system, but there will need to be a crane brought in to get it on the roof because of the gutter height. If anyone out there has addressed similar problems recently I'd be most grateful to hear your feedback. Thanks in anticipation!
