However, these systems have big draw backs. They are OK for small homes (great for flats) where space is tight. They are relatively expensive. They don't cope well with high water demands (they will limit the water flow in order to heat the extra volume). There are better systems for local conditions. A mains pressure gas storage hot water system is much better (lower purchase cost too) and a solar bosted gas storage hot water system is even better. With RECS and rebates.... not that costly. I would not install an Instantaneous Gas HWS in my house. Had the builder included it, I would have even paid to have it changed.
