What size TESY cylinder do I need?
Helping you size your TESY cylinder

When choosing the size of TESY cylinder you require, a good approach is to base this on the water volume required.
Some examples of appliances and their water consumption are;
- Average Shower - Approximately 50-60L of mixed hot and cold water
- Average Bath - Approximately 80L of water
- Average sink or Hand Basin - Approximately 3-9L of water
FREQUENCY OF USE: Another factor to consider is how frequently the appliances will be used as each cylinder has a stated warmup time . Using the same example above, if the shower was to be used twice in the morning one after another then you may wish to choose a slightly bigger size such as a 120L cylinder to avoid any heat up times between showers.
IMPORTANT NOTES:
- Always check the dimensions of the cylinder are suitable for where you intend to install the unit e.g.

- The cylinders are unvented and therefore are required by law to be installed by a G3 qualified plumber
I hope this helps!
