HTFs: Why can’t I use tap water in my ground source heat pump? 

Whilst water is technically a form of heat transfer fluid, it gives no protection from cold or metal corrosion. This is why it’s important to use a quality heat transfer fluid with both freeze and corrosion protection.  

Climalife’s range of heat transfer fluids each contain powerful hybrid inhibitors which can really help to protect the lifespan of a system.  

It is also recommended to use demineralised water when diluting a concentrated heat transfer fluid.
