Why is my BWT Fairland IPHCR15 Inverter running but not heating the pool?
- BBrent BakerAug 3, 2025
If your BWT Inverter isn't heating the pool water, even when running, it could be due to several factors. High heat loss might be the cause, so ensure the pool is covered when not in use, the pipes are buried or lagged correctly, and the pool walls of above-ground pools are well-insulated. Also, check if the filtration timer is set adequately, avoiding short cycles or nighttime-only operation. Exceptionally low ambient air temperatures can also affect heating, so waiting for warmer weather may help. Lastly, ensure proper air circulation by cleaning the evaporator fins.
