Battery Backup For Gas Hot Water Heater

At present one and only battery backup system available is HUGO. Though it’s designed specifically for tankless heater, it also works great for gas run appliances like gas hot water heaters. 

Battery Backup For Navien Tankless Water Heater

Navien also does the same. Navien doesn’t manufacture any battery backup for Navien’s tankless water heater. Naiven user manual said that a battery backup can be used, but they didn’t mention any requirement for that. So, Naiven users could use UPS or battery backup systems which perform best in the market. In such a case HUGO would be a good choice of battery backup for Navien tankless water heater.

You should have some technical information about a Navien before purchasing a backup system. Those are as follows:

1. When you operate your Navien water heater at half of its capacity, it requires about 150 Watts.

2. If you run just the recirculating system of your heater, it’ll require about 80 Watts.

3. At the time of stand by mode it needed 20 Watts.

Other Option of Backup System

Sometimes an inverter generator would be an alternative option (if you don’t have any prohibition to use that). For example, Navien NR-240A tankless water heaters require such an amount of power that can be produced by a small 2000watt Generac Inverter generator. This generator would be good enough for your water heater as well as the furnace.

If you want multi-day service from your backup system, you have to consider a perfect size solar panel for recharging it. That’s a need to invest more money. To save some bucks you can go for a cheap generator as Navien battery backup. 

Besides a tankless water heater, you can use some other home appliances. It’s true that 2000 Watts is not much. Though you can use this power to run many of your appliances if you use those wisely. To do that, you should have an idea about the power consumption of home appliances.  

Home appliances power consumption table:

2000 watt generator what will it run

From the above power consumption table, you have an idea that you can use many if you use them maintaining rotation. Typically, a 2000 watt generator could power a deep freezer (500 watts) and one element of the electric stove. Or you could use the freezer and a 650-watt microwave (using 1000 watts) as well as a few lights. Besides these, you can use other appliances like coffee machines, toasters, etc if you follow one or a few appliances at a time by considering the available power of the generator.
