How these alternatives compare
GASLAND Gasmart E Propane 5.8 GPM
The GASLAND Gasmart E shares the same 150,000 BTU output and 5.8 GPM flow rate as the Gasmart C. It uses propane and is rated for indoor whole-house use. The main difference is the physical footprint. The Gasmart E measures 16.7 inches wide and deep, with a height of 10.8 inches. This is a wider, shorter profile compared to the Gasmart C’s narrow 3.54-inch depth. If your installation space has height restrictions or you need a wider mounting area, this model fits. It offers identical performance but requires different spatial clearance. Choose this if your closet or utility room layout favors a low, wide unit over a tall, slim one.
GASLAND Gasmart E 5.8 GPM Indoor Propane Heater
The GASLAND Gasmart E model CE528LP is another 150,000 BTU, 5.8 GPM propane unit for indoor whole-house use. It weighs 33.1 pounds and measures 14.3 inches wide and deep, with a height of 24.7 inches. Compared to the Gasmart C, this unit is significantly wider but slightly taller. The Gasmart C is only 3.54 inches deep, making it much easier to fit in tight wall spaces. The CE528LP has a larger surface area. Select this alternative if you have ample wall width but need the extra height capacity. It provides the same hot water volume but demands more horizontal space during installation.
VEVOR 4.3 Gal Propane Tankless Water Heater
The VEVOR 4.3 Gal Propane Tankless Water Heater differs by offering precise temperature control rather than maximum flow volume. It is designed for indoor use with propane. While the Gasmart C delivers 5.8 GPM, this VEVOR unit focuses on stability for smaller households. It measures 13.8 inches wide and deep, with a height of 21.7 inches. This is a wider, boxier shape than the slim Gasmart C. It weighs 19.8 pounds. Choose this if you prioritize consistent water temperature and safety features over high flow rates. It is a practical choice for homes with moderate hot water demands where precision matters more than volume.
Camplux 5.8 GPM Propane Indoor Heater
The Camplux CA528WLP is a 5.8 GPM, 150,000 BTU propane heater for indoor whole-house use. It matches the Gasmart C in performance but differs in depth. The Camplux is only 6.5 inches deep, compared to the Gasmart C’s 3.54 inches. It measures 14.3 inches wide and tall, weighing 33.1 pounds. This unit is wider but shallower than the Gasmart C. It is designed for quiet performance in tight indoor spaces. Pick this alternative if you need a unit that projects less into the room than the Gasmart C. The trade-off is a wider footprint, but it offers stable heat with reduced noise.
Ranein 4.3 GPM Indoor Propane Tankless Water Heater
The Ranein 4.3 GPM Indoor Propane Tankless Water Heater provides lower flow rates than the Gasmart C. It outputs 4.3 GPM using propane for indoor whole-house use. Its dimensions are 14.2 inches wide and deep, with a height of 22.5 inches. This is a much wider unit than the slim Gasmart C. It is suitable for homes with moderate hot water demands. Choose this if you do not need the full 5.8 GPM capacity. It offers preset modes and stable performance. The Ranein is a practical option if your household usage is lower, allowing you to save on installation space while maintaining reliable indoor propane heating.
APUS 95,000 BTU 4.42 GPM Indoor Propane Heater
The APUS 95,000 BTU 4.42 GPM Indoor Propane Heater offers lower power and flow than the Gasmart C. It uses propane for indoor use. The APUS measures only 5.9 inches wide and deep, with a height of 20.6 inches. It weighs 19.2 pounds. This unit is wider than the Gasmart C but significantly less powerful. It prioritizes steady temperature and quiet performance over maximum flow. Select this alternative if you have limited hot water needs and value quiet operation. It is ideal for smaller setups where the 150,000 BTU output of the Gasmart C would be excessive. It fits well in tight spaces with a compact profile.
