Troubleshooting Tips

Heat pump error - Er46

Most problems that occur have a simple explanation so starting with the basics is always the best policy. A lot of basic problem solving comes down to the fundamentals!

Problem: Boiler Fires up and quickly turns off:
A boiler fires up, heats up very quickly and in less than a minute or so reaches set point and turns off.

This happens when heat is trapped in the boiler. What can cause this?

  • Air locks blocking the water flow
  • A seized or insufficiently sized circulating pump
  • Closed isolating or zone valves

Problem: System is running but hot water doesn’t heat up:

A heat source is running for many minutes or hours but the system or the hot water isn’t heating up. The heat must be going somewhere else—it can’t just disappear. What can cause this?

  • If a heat pump shows on its display that it is heating the hot water but the cylinder isn’t actually being heated, check whether the pipes to the HWC coil are getting hot. If not, the heat must be going somewhere else, probably the heating system.
  • If it is going to the floor, the heat can be traced through the pipes to the manifold and there should be flowrate through the floor loops. (If there is no flowrate, the heat cannot be transferred into the floor.)

Heat Pump Troubleshooting

Getting to know your Heat Pump can save you time when things don't go according to plan. We have put together a comprehensive two page error handling guide for you to go through when an error occurs on your heat pump unit or it's controller.
