Support with fitting the Mixergy cylinder.
What size connections does the Mixergy cylinders have?
The pipework connections on the Mixergy cylinder are 22mm compression fittings with a 3/4” BSP male thread. Depending on the installation's requirements, either a compression joint or threaded joint can be used.
Can Mixergy cylinders be fitted to a 15mm cold feed?
Yes, you will just need to fit a reducing connection on the cold water inlet so that the 15mm connection fits.
Does the Mixergy cylinders have secondary return connections?
Only Mixergy cylinders with a volume of 210 litres or more have secondary return connections.
Are Mixergy cylinders suited to use with secondary returns?
Mixergy cylinders of 210 litres or more can be connected to secondary returns. Cylinders with a smaller volume are not suitable for use with a secondary return system. Tuning of the secondary return pump speed and ‘on time’ are recommended to avoid excessive heat losses.
Is there a minimum flow rate required for the Mixergy cylinder?
There is no minimum flow rate required for the Mixergy cylinder to operate. However, if you swap a conventional cylinder with a Mixergy cylinder, this will not improve the home’s hot water flow rate as this is limited by the flow rate supplied to the cylinder. For unvented installations, we recommend 20 litres per minute for an optimal hot water experience.
Can I adjust the pump assembly at point of installation?
Yes, we recommend that the installer checks and tests all the connections on the top-up pump assembly to prevent leaks occurring.
Can I install a water softening with the Mixergy cylinder?
Mixergy recommend that water softeners are used in areas of hard water. Please note that the Mixergy warranty is invalidated for any installation in areas of >300ppm of calcium chloride. You can check the water hardness in your area by checking your local water supplier’s website.
