A Brief Buyer’s Guide
When going for a propane tankless water heater, make sure you are aware of what you are looking for. The variety of products on the market is ample and there are a couple of factors you should take into consideration in order to be satisfied with your purchase. However, there are 3 main factors that should be taken more seriously.
Firstly, temperature is importantnot only because it’s in the essence of the product, but also because you need to figure out the average temperature of the water in your area. This must be done so as to easily find a water heater for the specific temperature. Obviously, a lower average temperature may require a stronger propane water heater for your needs.
Secondly, the size of the propane tankless water heater should be carefully chosen if you’re going to install the unit inside. Outdoor tankless water heaters won’t have such a problem. No matter what type of propane water heater you choose, make sure you have some small space for the purpose. Bear in mind that size often corresponds to power and flow rate capacity.
Of course, you cannot enjoy the fruits of the water heater’s labor if its flow rate is not enough to supply all your appliances. For this reason, you have to make sure the maximum GPM surpasses the demand.
Last but not least, safety is quite important, so make sure your tankless water heater provides all the protection features like sensors, automatic mechanisms and such. If you’re going for an outdoor propane tankless water heater, make sure it has solid anti-freezing protection.
