House in winter ASHP

In >part 1< of this blog we covered some basic procedures that you can carry out on your Air Source Heat Pump system to make sure it is ready for the cooler months.
In part 2 we cover a few more tips, however these are more advanced. If you are unsure of how to carry out any of these procedures please do not attempt them.

If you did a test run as suggested in >part 1<, inspect any visible water pipework, checking that there are no weeps on any of the joints.  If you do find any it is advisable to get a plumber to repair the problem.

  1. Check the central heating pressure gauge.  If the gauge has dropped below 1 bar it is likely that the pressure in the system needs increasing.  If this is the case refer to the commissioning details the installer provided.  These should tell you the optimum pressure the system should be working at.

  2. Check the controller for any faults.  Any fault on the controller should provide you with an error code.  You can look at the ‘error fault code’ page on our website to help diagnose any problems.

  3. Check the inhibitor level in the system.  If this is low, the water in the system could potentially freeze during a cold snap.

  4. Check the circulation pumps are in good working order.

If you do need any assistance you can give us a call and we will be happy to assist.

Please make sure you have the following details:

  • Make and model of the ASHP
  • Is it serving underfloor heating / radiators / hot water or a swimming pool?

We hope this guide helped, make sure you check out >part 1< if you missed it.  Also take a look at our other article >Air Source Heat Pump Problems< for more information.
