How HUGO Works

How does HUGO Uninterruptible Power Supplies Work?
When your city power is normal, HUGO passes the electricity directly to your tankless water heater while monitoring your AC input.  When and if your AC input drops outside of voltage safety zone, HUGO will immediately transfer to battery (DC) mode.  
When you have a power outage, within 12 milli-seconds (if no flow sensor is installed), the HUGO unit will direct and convert the battery's 12VDC battery power to 120VAC pure sine wave electricity to your appliances.
If the flow sensor is installed and you have a power outage, HUGO will stay in standby mode until the flow sensor receives a water flow signal.  At that time, HUGO will start converting DC 
to AC and allow your tankless to power up.  When you're done using water and shut off all the taps, HUGO will stop sending power to your tankless after 5 minutes to preserve the battery for prolonged actual use of hot water.  If your typical hot water use is one hour per day the HUGO deep cycle battery can provide adequate power for 3-7 days of regular operation (depending on the actual power consumption of your particular tankless water heater).
Now, you will never have to worry about natural disaster caused power outages or your utility company doing maintenance or repair work.
IMPORTANT: Ceramic heaters are used inside most of the tankless water heaters to prevent the
heat exchanger from freezing and causing leaks that could be expensive to fix or replace.  If you lose power to your tankless water heater, this feature won't work.  With HUGO installed, the integrated temperature sensor will operate in the same way as the ceramic heater does.  If you lose power and the outside temperature drops below 37 deg F, HUGO will send the battery power to your tankless system regardless of the water demand.  This will ensure that your tankless water heater has the power it requires to protect heat exchangers from freezing.
DISCLAIMER:  HUGO WILL NOT PREVENT FREEZES THAT OCCUR IN YOUR PLUMBING PIPES WHICH MAY CAUSE A RUPTURE ALONG YOUR PLUMBING LINE.  IF YOUR PIPES FREEZE AND RUPTURE, THE RUPTURE NORMALLY OCCURS AT THE POINT OF LEAST RESISTANCE, WHICH MANY TIMES IS AT THE BEND IN THE HEAT EXCHANGER OF YOUR TANKLESS WATER HEATER.  HUGO'S ONLY FUNCTION IS TO ENSURE THAT THERE IS POWER TO THE WATER HEATER.  CHECK WITH YOUR WATER HEATER MANUFACTURER ON FREEZE LIABILITY PROTECTION.  HUGO WILL NOT WARRANT ANY LIABILITIES OCCURRING FROM FREEZES.
