Boiler Water Conductivity Measurement Fundamentals
· TDS = 5 000x0.7μS/cm. TDS = 3 500 ppm. Alternatively the battery powered temperature compensated conductivity meter shown next is suitable for use up to a temperature of 45°C. It is necessary to measure the conductivity of the boiler water inside the boiler or in the blowdown line.

The temperature can be raised closer to 400°F if needed to remove more water from the glycol. 2. Check the glycol-to-glycol heat exchanger in the accumulator for leakage of wet rich glycol into the dry lean glycol.

· Any water that is not required will be sent back to the boiler to be re-heated to 82°C. The temperature range for the thermostatic RWC mixing valve is from 35°C to 65°C. Between the mixing valve and the flow manifold an underfloor heating pump must always be fitted to provide circulated water for the heating loops.
