Can I Use a Hot Water Heat Pump with a Tankless Water Heater?

Written By EnergyLabs  |  Hot Water Heat Pumps 

A hot water heat pump is a great way to heat your home’s hot water supply, but can it be used with a tankless water heater? The answer is yes – in fact, a hot water heat pump can be used alongside almost any type of hot water system.

In order to get the most out of your hot water heat pump, you need to make sure that it is installed correctly. This will mean making sure that any existing tankless water heater is compatible with the heat pump, and that the two are properly connected. If you aren’t sure whether your system will work with a heat pump, it’s best to get an expert in to check it out for you.

When installing a new system, you should also think about whether you want to install an additional tankless water heater or use the one you have already. While tankless systems provide instant hot water and don’t require as much energy as traditional storage tanks, they can be more expensive upfront and may not be suitable for all homes. On the other hand, if you already have a tankless system installed, then adding a heat pump could be a cost-effective solution – plus it will help reduce your energy bills in the long run.

It’s important to note that when using both a tankless water heater and a hot water heat pump together, there may be some restrictions on how much hot water can be produced at once. As most tankless systems only produce around 2-4 litres of hot water per minute, this means that if more than this amount is needed then your system may struggle to deliver what is required. In this case, it may be necessary to install an additional (or larger) tankless unit in order to meet your needs. It’s always best to check with an expert before making any changes so that you are able to get the most from both systems.

To sum up, yes – you can use a hot water heat pump with a tankless water heater if they are correctly connected and compatible with each other. However, depending on how much hot water your household requires there may be restrictions on how much can be produced at once so ensure that this has been taken into consideration when deciding which system would work best for you.
