At Maroochydore Hot Water, our quoted prices are ALL inclusive for your hot water system, fully installed to meet all council regulations. Unlike some other businesses that quote you a price and then add extra costs for valves, we do not do that. All hot water systems require a certain amount of valves that are not included with the hot water system. Therefore, we include everything in our pricing, as they are required. Not including them in the quoted price is a tactic used to make the initial price seem cheaper and then overcharge you for the valves later.
