What are the high limit trip points?ebizuniverseThe auto reset high limit has a trip point of 160°F. The manual reset high limit has a set point of 200°F.
Frequently Asked Questions
Speaking of temperatures, what are the temperature capabilities of the NextGen Boiler?ebizuniverseThe boiler can be operated on application requiring water temperatures between 85°F to 140°F.
What happens if there is a failure of a heating element?ebizuniverseElement failure is very rare and can be attributed to poor water quality. However, in the case of element failure the heat exchanger should be replaced with the exact kW type that matches the kW output of the boiler. Ex) A 14.4 kW boiler should have a 14.4kW heat exchanger replacement.
Is there a recommended pH level?ebizuniverseThe pH level is very important to test. This will extend the longevity of the boiler while maintaining reliability and efficiency. The best pH for NextGen Boilers is a level between 6-7. Too high of pH can corrode components.
What is the heat exchanger made of?ebizuniverseThe heat exchanger is made of stainless steel (304 type).
What is the total capacity of the NextGen Boiler? How about the heat exchanger?ebizuniverseThe total capacity is 1.06 gallons whereas the heat exchanger is .5 gallon capacity.
Is Propylene Glycol acceptable to use?ebizuniverseYes, keep in mind that the viscosity of the freeze protection fluid can result in lower BTU output and also can change the flow characteristics of the circulator pump. Do not use more than 50% ratio of propylene glycol.
Will the primary circulator pump be suitable for all radiant applications or designs?ebizuniverseThe pump is not a one size fits all. Each designer should take into account the Disposable/Available Pump Head curve found on page 4 of the NextGen Boiler installation manual. Failure to comply with this curve may result in problems with heating the application properly. Depending on how the system is designed, the primary pump can handle most applications where a 20 Delta T is used. Note that the 14.4 kW model likely will require a secondary pump when installed with hydraulic separator or closely spaced tees.
Does the boiler have a post/purge operation?ebizuniverseYes, the post purge sequence is programmed for 20 second pump operation after the thermostat temperature has been satisfied and opens the TT call for heat on the boiler.
What happens to the boiler upon a power outage?ebizuniverseThe boiler will resume normal operation once 240 VAC power is restored. The control panel will continue to hold the memory of the pre-programmed set points set by the user.
