Backup Power Supplies and Protection for Paloma Water Heaters and Convector 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 and the 26 l/m 64 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 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 can offer is;

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

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
