threefold question:
1. Does this include heaters/boilers for domestic hot water system that exceeds the specified capacity y water consumption. We have a hotel project where the hot water system will exceed the specified capacity (500,000Btuh) and hot water consumption (100,000 gallons).
2. Also in series we have a solar hot water system providing pre-heating of the water and the question is do we meter the water through the boilers or we meter the building consumption of hot water?
3. If we need to meter the hot water consumption do we do this in the hot water upstream of the mixing valve or downstream where we meter the total cold water consumption of the system?
