what is an indirect fired water heater
What is an Indirect-Fired Water Heater? Also referred to as a 'sidearm tank' or an 'indirect water heater,' an indirect-fired water heater is a high quality, thermally efficient storage tank that has an internal heat exchanger which heats water in the tank by means of hot water circulating from the boiler.
What are the main advantages of an indirect hot water system?
The greatest advantages of the indirect water heaters are the significant reduction of flue losses. Less maintenance – no additional burners to maintain. Less cost – no additional venting required or fuel lines to run. Better performance – more available hot water with quicker recoveries.
