ok well it's doable should be no problems but we need more information.
What water temp do you need to supply enough btus to your coil?0 -
Why?
Tankless heaters are designed for low flow, high delta T operation. The small diameter HX tubes typically require a high head circ to get any performance, and may not ramp to full burner output with a pumped flow.
Use a boiler designed for the application and enjoy all the added benefits, ODR, ramp and delay functions, warranty, and piece of mind.
You have chosen a good brand, but the wrong product, look into their boiler options.Bob "hot rod" Rohr
