Backup Power Supplies and Protection for Paloma Water Heaters and Convection Space Heaters

In order to provide the most efficient, reliable and safest form of gas water & space heating, Paloma units require a constant electrical supply when operational.  The electrical consumption is very low, for the Gas Water Heaters the 20 l/m unit requires 61 watts, the 26 l/m 64 watts and the 27 l/min 67 watts.  The PJC-25 Convector Heater uses 31 watts when running. 

The use of electric sensors within the units allows precise computer controlled delivery of hot water, using only the exact amount of gas required to raise the set water temperature.  The convector space heater also uses the same principles to heat efficiently and as directed.  Sensors within all units ensure safe use of gas and digital analysis/diagnosis of any problems/issues that may arise

In the event of a power outage, any (non-square wave generating device) can be used to provide alternative power.  The use of an inverter or larger UPS can provide reliable back-up power.  Because Paloma units do not require much power, battery sizing is important to ensure longer use.  As a cost effective alternative we offer;

Paloma Gas UPS

UPS units are kept plugged in and operational at all times and do offer some protection against electrical surges etc.  In order to get the longest use from the UPS, best practice would be to turn the UPS off, and only turn on when the Paloma unit is required – then switch off after use.  Please Contact Us for pricing and availability.

Paloma Modifications

Paloma provides adapted UPS with a changeover switch installed inside. As the unit should always be connected to the geyser, when the power goes down, the UPS will automatically switch off – this preserves the battery life. When the user wants hot water, they manually turn on the UPS. When they are finished, the user turns the unit off again to save battery. When the power returns the user needs to turn the unit back on again.

Total usable back power should be about 1.5 hours – which is plenty for 5 minute showers!

These units have only been tested and adapted for Paloma Gas Geysers.

Longer lasting units

For a more robust and longer lasting power back-up alternative, the Inverex UPS series can offer the ability to run several electrical devices during power outages.  The Inverex systems include a large deep cycle battery with the ability to power TV’s, PC’s, Security systems etc and can operate Paloma Gas products for extended periods.
