Are issues with boiler water temperature common in tankless coil water heaters?

Issues with boiler water temperature are indeed common in tankless coil water heaters because these systems are designed to heat water on demand using a coil that runs through a boiler. When the boiler's water temperature is not set correctly or does not reach the desired level, it can lead to problems such as inadequate hot water supply or inefficient heating.

Since tankless coil systems depend on the boiler to maintain the appropriate temperature for water heating, fluctuations or inconsistencies in the boiler’s performance—such as thermostat settings, burner function, or overall boiler health—can directly influence the output temperature of the hot water. This makes it crucial to regularly monitor and maintain the boiler to ensure optimal performance of the tankless coil system.
