Case Study: Custom Anti-Corrosion Hot Spring Heat Pump for Mountain Hot Spring Resort

This mountain hot spring resort is located in a highland cold area. The spring water contains sulfur and mineral substances. Standard stainless steel heat pumps suffered corrosion and short service life. The resort needed a heating system to keep multiple open-air hot spring pools at 38–42℃ in winter, with limited machine room space. The owner rejected coal / oil boilers for emission restriction and high fuel cost, and looked for a customized heat pump solution.

After site parameter collection, water quality report analysis and thermal load calculation, our team designed a non-standard integrated hot spring heat pump unit:

1. Heat exchanger: titanium alloy, anti-corrosion for sulfur-rich spring water
2. Custom working condition: designed for -15℃ ambient temperature stable heating
3. Custom size: compact cabinet to fit narrow machine room
4. Custom control: separate temperature setting for different hot spring pools, automatic constant temperature + remote cloud monitoring
5. Modular combination, easy to expand if resort adds new pools later

✅ Pool temperature stable between 38~42℃ in cold winter ✅ No corrosion issue after 12 months running ✅ Energy saving: around 60% operation cost down vs oil boiler ✅ No exhaust emission, meet local environmental regulation ✅ Simple maintenance, remote fault alarm

Customer quote:

“Standard heat pumps could not work for our sulfur spring water. The custom titanium heat pump unit solves our corrosion trouble perfectly. Stable heating in cold winter helps us keep good guest experience all year round.”
