If you’re traveling in an RV, hot water is not just a luxury—it’s part of everyday comfort. Whether you’re showering, washing dishes, or simply cleaning up, a reliable water heater makes life on the road easier. Two brands have become favorites among RV owners: Apus and Girard. Both offer tankless water heaters, but which one is truly better? To help you decide, we’ll break down the differences, compare performance, and look at real-world experiences. By the end, you’ll know exactly which model fits your RV lifestyle.
Why Rv Tankless Water Heaters Matter
Traditional RV water heaters store hot water in a tank. When the tank runs out, you must wait for it to refill and reheat. Tankless water heaters solve this problem—they heat water instantly, so you get endless hot water as long as you have fuel and water supply. For RVers, this means:
- Shorter wait times
- More efficient use of energy
- Less worry about running out during a shower
Both Apus and Girard claim to deliver these benefits, but their actual performance, reliability, and ease of use vary in key ways.

Apus uses corrosion-resistant materials. The heater is designed to last at least five years with normal use. The freeze protection system reduces winter damage, but regular maintenance is still needed. Users report fewer leaks and less scale buildup compared to some competitors.
Girard
Girard’s reputation is built on reliability. Units often last 6–8 years if maintained well. The microprocessor adds a level of protection against overheating and water pressure problems. Service parts are widely available, and many RV shops are familiar with Girard systems.
Key Insight
- Maintenance matters: Both brands need regular cleaning and filter checks. Neglecting these steps leads to scale, lower efficiency, and more repairs.
Energy Efficiency And Water Conservation
Apus
Apus heaters are efficient, using propane only when hot water is needed. The higher flow rate means you can use more water at once, but this can drain your water tank faster if you’re not careful.
Girard
Girard’s lower activation flow helps conserve water. It uses slightly less propane per gallon heated, and the microprocessor optimizes burner use. This is helpful for RVers who want to stretch their water and fuel supply on longer trips.
Example
If you have a 40-gallon water tank, using the Apus at full flow (2. 6 GPM) will empty your tank in about 15 minutes. With Girard at 2. 0 GPM, you get about 20 minutes of continuous hot water.
User Experience And Comfort
Apus
Most Apus users praise the fast startup and steady temperature. The digital control panel is easy to read, even for non-native English speakers. However, a few report temperature drops if water pressure changes quickly.
