What type of pumps will work with the HOTTAP?

When it comes to pumping water there is a vast amount of options available to choose from however you need to be certain of the requirements in your system otherwise you are likely to find that the particular pump you have is not fit for purpose.

The Joolca branded pump is specifically designed to be used with the HOTTAP, however if you have your own pump or have a use case with the Joolca pump won't suit, that is perfectly fine. 

General Specifications Required: 

When it comes to the HOTTAP Hot water system the ideal specifications for the pump are that it flows at least 6 litres per minute and no more than 12. You are also looking for a pressure level around 60 PSI. Meeting these operating ranges will ensure optimal operation from the HOTTAP system.

Main types of pumps you may come across are:

Centrifugal water pumps:

These style of pumps generally consist of one or more impellers typically driven electrically. You will find Bilge pumps fall under this category. These style of pumps are not suitable for the HOTTAP due to their nature of providing high water flow rates but low water pressure. We have found from past experience that generally these will not have the required water pressure to activate the pressure switch in the HOTTAP.

Positive displacement pumps (AKA Pressure Pumps):

PD pumps do not have impellers, instead, they consist of either rotating or reciprocating parts and generate high pressure to push the water along the system. These style of pumps will generally provide lower flow rates than centrifugal style pumps however provide much higher water pressure. These style of pumps are ideal for the HOTTAP system and as long as the specifications are within 6-12 litres per minute and around 60 PSI it will be perfect for the HOTTAP system.
