All You Need to Know About Buying 12 volt heater for trucks
The most important aspect of any RV heater is safety. Make sure that the unit you’re buying has a safety shutoff timer, overheat protection, and a completely sealed fan to avoid carbon monoxide poisoning.
Energy efficiency should also be one of the biggest considerations when buying an RV heater. Make sure that the unit you buy has an energy factor of at least 0.80 to save on energy bills. Most heaters will also have an energy consumption rate stated in watts, so look for one that is between 500 and 1000 watts.
Size and installation compatibility are very important as well. Make sure that the heater you’re buying will fit into your RV’s space. If you’re buying a wall mount heater, make sure that it can be flush mounted into your wall. If you’re buying a ceiling or floor heater, make sure that it can be installed accordingly.
Aside from the physical specifications, the installation process should be easy. Most heaters will have clear instructions on how to install the unit, but if you’re having trouble following instructions, get in touch with an RV technician to avoid mistakes.
If you’re buying a heater with a thermostat, make sure that it has a fully adjustable thermostat. A thermostat that only controls the high and low temperature settings will be inefficient and costly to use.
Most RV heaters will come with some sort of warranty. Make sure that the heater you’re buying has at least a one-year warranty and a good customer service support. A warranty will protect you from any manufacturing defects, and good customer service will help you out if you run into any issues with the installation.
LED lights, night lights, and motion sensors will add to the convenience and safety of a heater. If you’re buying a heater with LED lights, make sure that they’re bright enough to be used as a primary light source. Night lights will add a bit of convenience to a heater that’s installed in a bathroom or bedroom, and motion sensors will turn the heater on or off depending on your presence.
Heating power and temperature control are the most important factors of any heater. Make sure that the heating power of a heater is at least 1500 watts and that it can heat an enclosed space of at least 1800 square feet. Temperature control is also very important, so look for a heater that can be adjusted between 60 and 70 degrees Fahrenheit.
Portability and convenience are more important for
