There are three different types of hot water systems these can be chosen to provide your needs as a person with a busy or unusual houred work life. The three types of Hot water systems are storage systems, on demand hot water system and solar hot water systems
Storage Hot water Systems.
Like the electric kettle in your kitchen, energy is converted to heat and by an element and the water is heated. Convection movement of the heated water inside the tank moves or stirs the water, Once the water is at a reasonable temperature to sit at a thermostat is triggered and the elements are energized and the water temperature is constantSome types of hot waters systems are specially are designed to be installed indoors. Indoor gas storage hot water systems are designed to be flued or vented to outdoors.
On Demand Hot Water System
These units heat water only when supply is required and can be incorporated into a hot water systems that use storage tank and solar heating. Most of these types of systems are triggered by a flow sensor that lets the pipes that are surrounded by heat padding increase temperature. The ongoing costs of maintaining an instantaneous system and the initial cost of supplying and installing the system may not actually make it any better an investment than a standard gas storage, the best way to use a On Demand is to have it close by to a tap point.
Solar Water Systems
These are the most cost efficient water systems, there are two types of systems for this. There is the active system and the passive system, the active system utilizes a pump to circulate the water through the storage tanks. Passive system requires draw off of hot water to allow cold water into the storage tank into the roof.
