Connecting and Testing Vertical Collector for the Heat Pump

The first photo is showing a testing procedure for vertical collector. Each vertical collector should be tested before connected to the heat pump. It is very small possibility of leaking, but you must be 100% sure. Testing is accomplished with water and a water pump (hand driven) which can produce a pressure up to 5 bar. Pressure meter must be stable at least 1 hour – 1 hour the same pressure.

The second photo is showing pipes already connecting vertical collector and heat pump. There is a 0,75 to 1 meter deep channel where pipes are placed.
