How long does an indirect water tank last?
15-20 years
How long does an indirect water heater last? Indirect water heaters typically last 15-20 years.
How does an indirect heating system work?
The way an indirect cylinder works is that an external source is used to heat the water prior to being transferred to the indirect cylinder. A central heating boiler may be used for this purpose, or another external heating source such as solar panels, for example. Cold water is drawn into the tank from a water source.
How is an indirect water heater controlled?
The temperature in the indirect water heater is controlled by a thermostat mounted on the water heater tank. That thermostat turns on or off the circulator pump. Separate, independent temperature controls back in the heating boiler actually turn the heating boiler’s burner on or off as needed.
What is the difference between direct and indirect unvented cylinders?
Direct and Indirect A ‘direct’ cylinder is heated via an electric immersion and does not work with gas, oil or heat pump systems. An ‘indirect’ cylinder has coil running through the cylinder. The heated coil imparts its heat onto the fresh (potable) water in the tank that is used for washing or showering.
How does an indirect hot water tank work?
An indirect hot water cylinder requires an external device to generate the hot water, such as a boiler. Once you’ve determined whether your cylinder is direct or indirect, there are two further types of cylinder you could have. It could be a vented cylinder or an unvented cylinder.
Which is better a direct or indirect water heater?
This indirectly heats the water inside the cylinder which comes out of your taps .The coil inside the cylinder acts in the same way as an immersion element would. Advantages of an indirect cylinder: Indirect water heaters tend to be the more efficient option for many homes, even if they require a storage tank.
How does an indirect water supply system work?
The rising main also feeds a storage tank at a high point in the building from where the water is fed to all the other taps etc using gravity. The items identified in the illustration above (NOTE that the central heating has been omitted for clarity) of an indirect water supply are:
What are the disadvantages of an indirect hot water cylinder?
Disadvantages of an indirect cylinder: If heating your hot water is totally reliant on an external source like your boiler and that boiler should fail… you might end up without any hot water while you get that issue sorted.
