How does a HIU impact water pressure and temperature in my property?

The impact of a Heat Interface Unit (HIU) on water pressure and temperature in your property depends on several factors, including the design and specifications of the HIU, the central heating system it's connected to, and the individual requirements of your property. Generally, HIUs are designed to maintain consistent water pressure and temperature within acceptable ranges for domestic hot water and space heating needs. However, improper installation, sizing issues, or malfunctions in the HIU can potentially affect water pressure and temperature. It's essential to ensure that the HIU is properly installed, sized, and maintained to minimise any adverse effects on water pressure and temperature.
