Differentiating Between A Storage or Continuous Flow Hot Water System
The first step to choosing the perfect hot water system for your household is deciding upon whether your house and lifestyle is suited to a storage hot water system or a continuous flow instantaneous hot water system. Cost may also be a factor.
A storage hot water system heats the water and then stores it in an insulated tank and makes it available for use during the day. These types of hot water systems will run best on solar energy, natural gas or even off-peak electricity. They can also run on peak electricity, solid fuels and LPG, but this is not recommended as it can end up being quite costly.
Storage hot water systems are available as a main pressure unit or a constant pressure unit. A main pressure hot water system delivers the hot water at the same pressure rate as cold water; these are best situated at the ground level. A constant pressure unit delivers the hot water at a lower pressure than main pressure units; these are best situated at the roof level. Although constant pressure units are about the same price as a main pressure unit, the cost of installing a constant pressure unit can be up to 4 times more expensive.
A continuous flow hot water system will instantaneously heat the water as the water is required. Because continuous hot water systems do not store water, they are typically smaller than storage hot water systems, making them easier to install in tight places. A high quality standard continuous hot water system can deliver an adequate amount of hot water to two points at any one time. When a hot water system is required for the roof level it’s recommend that you choose solar power because both the pipes and power are already situated in the roof.
