5 Warning Signs Your Evinox HIU Needs Repair

Your Heat Interface Unit, or HIU, is the heart of your home heating. When it works well, you barely notice it. It keeps your water hot and your radiators warm. But these units can fail over time. Knowing the signs of trouble helps you avoid a cold home or a high water bill.

1. Water Not Heating Up

You turn on the tap and expect hot water. If the water stays lukewarm or cold, something is wrong. It might be a faulty valve inside your unit. This is a common issue that needs a look from a professional.

2. Strange Noises Coming From the Unit

Your HIU should be quiet. If you hear banging, clicking, or grinding, pay attention. These sounds often mean parts are worn out or blocked. Ignoring these noises can lead to bigger, more expensive breaks later on.

3. Leaking Around the Base

Water on the floor is never good. Even a small drip can damage your floor or nearby walls. If you see water pooling under your unit, shut off the supply if you can. Then, call someone who knows these systems well.

4. Pressure Gauge Fluctuations

Check your pressure gauge once in a while. It should stay steady within a specific range. If the needle keeps dropping or jumping high, your system is struggling. It might be a leak in the loop or a faulty pump.

5. High Energy Bills

Do you notice your bills climbing for no clear reason? A struggling HIU works much harder to keep up with demand. It might be cycling on and off too often. If your system seems to be running non-stop, it is probably time for a check-up.
