ENSURE CONTINUITY OF HEAT AND HOT WATER EVEN WHEN THERE IS TOTAL POWER BLACKOUT

Backup Power for Gas Water Heaters:

This special backup power supply for gas heaters and gas water heaters is ideal for locations with poor power quality or regular power cuts. Like the uninterruptible power supplies (UPS) used for computer and alarm systems, it automatically switches to a rechargeable maintenance-free battery whenever there is a power blackout or brownout.

Why do I need backup power for gas systems? Gas heaters and gas water heaters often require electrical power to provide the spark for gas ignition, as well as running an electronic controller and small internal fan. In the event of a total power failure (blackout), as there is no electrical power available to ignite the gas, there simply will be no heat or hot water. The Helios Power Solutions SPS 320, apart from cleaning the power, charges its own batteries, keeping them ready for the next power failure (blackout or brownout event).

Operating Instructions

  • SPS320 must be treated like any other electronic appliance and be installed in a dry environment, so an electrician may be required to fit a through wall power connection (for water heaters installed outdoors),  or a weather-proof enclosure  larger than the SPS320 (to allow for cooling) could be mounted next to the water heater.
  • The runtime is limited (see datasheet). The stated times are for continuously supplying hot water,  but these units will also switch off automatically after 1 hour of idle with no load (only when there a power failure).   During a power cut you could further extend the battery life by switching the SPS320 off when you have finished running the hot water and switching it back on again when required.   If the anti-frost system operates in the water heater, the battery will discharge faster. The battery will be automatically recharged over a few hours once power returns.
  • The SPS320 may be used in conjunction with a generator so that it supplies power until a generator is connected, at which point the generator power will be supplied to the gas appliance and also recharge the SPS320’s battery,  if desired.   Please be aware that this may not be compatible with low-quality generators.
  • Typical battery life is about 3-6 years.   Battery runtime may be tested by turning the input power off,  and if you do not want to run the gas hot water to do this test you can connect a 60W  light bulb in place of the gas controller to the output of the SPS320.
