I have 5500W in my HLT and always heat 20 gallons from about 50-60F (ground water temp) up to about 150F mash temp. That takes an hour for me and I do it while I prep for the brew day.
You have 5500/1440 or 3.8 times less power so it will take you almost 4 hours to heat assuming your ground water's the same temp as mine. It's probably a bit warmer so assuming 3.5 hours. That's a long wait.
