Page 6: Insufficient Hot Water
Insufficient Hot Water Is the water heater undersized for the application There are many methods of sizing various applications, i.e. ASHRAE sizing tables, or ASPE domes- tic water heating design manual, re-confirm the water demand required for the application. Re-confirm the flow rates of the fixtures. Was the tank sized for shower heads at 2.0 gpm, when the actual heads are 5.0 gpm? Use a bucket and a stopwatch to determine fixture flow rates. -

Insufficient Hot Water Is the circulator between the boiler and the water heater properly sized to provide adequate flow for maximum BTU transfer? Pipe Size Flow Rate BTU's Transfer 3/4" 3 to 7 gpm 50 to 100 MBH 1" 8 to 15 gpm 100 to 180 MBH 1 1/4"... -
Page 8: Boiler Operating Temperature
Insufficient Hot Water What is the location of the thermostat bulb? A bulb inserted completely at the bottom of the drywell will initiate a quicker response for a call for heat. This is typically the position of the bulb required for applications in which there are large draws of domestic water. -
Page 9: Excessive Water Temperature
Excessive Water Temperature Excessive water temperature is usually the result of stacking within the water heater. Stacking is the occur- rence of various water temperatures layering within the water heater with the hottest water in the uppermost layer. This layering or stacking effect typically occurs during small draws of hot water (typically less than 25% of the storage capacity) which are long enough to create a call for heat on the thermostat, but are short enough not to deplete the stored energy within the tank. -

Is the expansion tank on the boiler side properly sized? The additional quantity of boiler water contained in the outer tank must be considered when sizing the boiler side expansion tank. Boiler Side Model Capacity gal. TR-20 TR-30 TR-36 TR-45 TR-60 TR-75... -
Page 11: Boiler Operating Temperature
Temperature/Pressure Relief Valve Lifting or Weeping Is there a thermal expansion tank installed on the domestic supply piping and is it properly sized? A thermal expansion tank is required if the domestic supply piping includes a backflow preventer or pressure reducing valve. Ensure the potable water expansion tank is properly sized according to the water heater volume and supply pressure. -
Page 12: Water On The Floor
Water on the Floor Is the source of the water from the tank? Check for possible water seepage through foundation cracks. Did the water appear after a heavy rain? Is the source of water from the T&P relief valve? Place a bucket under the discharge piping of the T&P relief valve and monitor it for a day or two. This is a procedure that can be done by the homeowner. -
Page 13: Top Of Tank / Insulation Wet
Top of Tank / Insulation Wet Is the source of the water from the tank? Check for possible overhead pipes leaking onto the tank Check all connections - domestic connections, air vent..Check the connections to the water heater. Are they loose? A build-up of corrosion around joints is a sure sign of a leak. -
Page 14: Water Smells / Taste Bad
Water Smells /Tastes Bad The hot water smells like “rotten eggs” The most common cause of water to smell like “rotten eggs” is a non-toxic sulfate reducing bacteria. The bacteria usually enters into the water system through a break in the supply piping or during construction/main- tenance of the supply piping. - Page 15 Water Smells / Tastes Bad Hot water from the faucet appears milky When water is initially drawn from the faucet it appears to be milky or cloudy, but it becomes clear after the water is allow to stand for several minutes. This is usually an indication that the water contains high levels of soluble gases such as oxygen, chlorine, carbon dioxide, hydrogen sulfide or others.
- Page 16 Water Smells / Tastes Bad Discolored water from the hot water faucet The water from the hot water faucet appears discolored, either rusty, brown, black or yellow. Because the inner tank is stainless steel, which by its nature is resistant to corrosion, the problem is not tank related. The problem is usually a non-toxic iron reducing bacteria that is commonly found in soil, well water, water treat- ment plants and piping systems.
