How To Choose The Best Propane Heater For High Altitude?

If you are an inhabitant of a high altitude, you already know that a usual natural gas water heater can’t serve you properly. That’s because at a high altitude there is a low partial pressure of oxygen. That’s why high altitude water heaters require more air flow than usual ones. 

If you already own a regular furnace, then you will require a kit that will assist in further adjustments. However, if you wanna go for the best propane heater for high altitude then there are several key points that you must consider right away!

Build Quality: 

The first & foremost thing to consider before investing in the water heater is its build quality. It should be durable enough to support two to three years minimally. 

A high quality furnace can easily grasp a large amount of air and heat it up internally. This extra volume of air will assist in heating up the water even at a high altitude. In terms of high altitude tank less water heaters, the users must be very conscious about this feature specifically.

Weight & Compactness: 

A classy and efficient water heater is usually lightweight & compact. If the user owns a small house, we would highly suggest checking out these features. A compact heater can easily fit within the cabinet space or underneath the sink. Lightweight ones are super suitable if he plans to install the heater on the wall, ceiling or floor. 

Easy of Installation & Usage:

Going for a unit that is easy to install is certainly a wise decision. In this context, we would highly recommend going for an authorized professional installation. That’s because many users face severe consequences after several months just because the installation procedure wasn’t accurate. However; if you have enough experience and confidence, go for it!

Nowadays most water heaters can be installed just at the point of requirement. Connect it with the water line , set the valves up and the heater is good to go. Ease of usage is also a key point as the ultimate aim of this water heater is to make the daily life comfier and more convenient.

FAQ

What is a high altitude water heater? 

High Altitude water heaters are specialized units which are designed to function even at the low density of oxygen. These devices are quite different from regular ones as they require a high amount of air flow. 

Do tankless water heaters work at high altitude? 

A regular gas tankless water heater can’t function at a high altitude. They can perform properly if the habitat is maximally 2000 feet above the sea levels. However a modified tankless water heater with proper air & fuel balance can function efficiently even at high altitudes.

What size propane line do I need for a tankless water heater? 

Generally we would prefer around ¾” propane line to ensure a constant gas supply to the tankless heater. However, if the gas line is too short; a ½” propane line might also work. This is the minimum requirement in the UK, Canada & USA.
