Get the Hot Water System your Home Deserves

There are several ways of heating water in your homes. Hot water systems are grouped into three main heating types which are: instantaneous, unvented and vented hot water systems. Below is a description of each type and how they function.

1.) Instantaneous hot water system.

This method does not require storing hot water rather it involves heating the water using gas or electricity to a temperature that is usable by individuals at homes. If using power, it involves using a coiled element for heating that heats the water rapidly just like an immersion heater or a kettle does.

2.) Open vented hot water system.

A cylinder where the water is heated from. The heat comes from either directly from boilers or indirectly through a coil fitted in the cylinder inside.
A tank for storing cold water which is then supplied to the cylinder for heating. It is positioned just above the cylinder to allow the flow of water into the cylinder.

Open vent pipe that helps the hot water system cope up with expansion of water. It ends in the cylinder to control hot water expansion in the system.
A source of heat that is used to heat the water.

3.) Unvented hot water system.

Unlike open vented systems, unvented systems have more parts and do away with storage tank, and the pressure they operate on is quite higher compared to open vented systems. Some of the additional elements include:

Pressure valve: it is a reducing pressure valve placed on the main pipe bringing in cold water to reduce the pressure of incoming water trying to keep it at a constant pressure.

Line strainer: placed on the inside of the cold water pipe to filter out any particles coming in with the cold water.

The tundish: this is a device used to alert users of any fault in the system by allowing water to flow out through the safety valve.
