In Need of Repair

This system was only a couple of years old and had been plagued with a history of overheating, under performing and general component failure since installation. We were asked to review and repair the system.

This was a large evacuated tube array, serving a seasonal outdoor pool.

The Problem;

  • Seasonal load with no means of overheat protection
  • Undersized solar circulator and heat exchanger could not dissipate heat even under normal conditions
  • Lack of design flow on load side
  • No variable speed pumping left energy on the table
  • No preheat configuration for domestic hot water
  • Poor control was actually cooling domestic hot water tank via solar

The Solution;

  • Share array with adjacent community center, year round domestic hot water load
  • Design for steamback overheat protection
  • Repair hydronic systems including variable speed, boilers, pool, domestic hot water loads and space heating
  • Integrate building automation system (BAS) for reliable control and remote access
