How to Choose A Proper Tankless Propane Water Heater For Home Use
Tankless water heaters are becoming more popular since recent years. Another thing is propane tankless water heaters produce more a larger temperature rise compared to the electrical models. They are also more powerful. But how can you know which one is ideal for you?
Hot Water Needed
Before purchasing a tankless water heater, you need to make a few considerations—for instance, the hot water needs for your entire household. The rating of the tankless water heaters is by the possible maximum temperature rise at a particular flow rate. You need to determine the amount of water needed at peak demand and how much heating the incoming cold water needs.
To do this, you are required to list all the fixtures in your house that require hot water and sum up their flow rates. You can check online or refer to their documentation if you are not sure of the flow rates. This helps you to know the desired flow rate required by the water heater. You can reduce flow rates by installing water fixtures with low-flow.
Also, you need to ascertain the incoming water temperature and then calculate the temperature rise. You can get this by subtracting the temperature of the incoming water from the output temperature that is desired. Depending on the geographical temperature, the temperature rises will vary.
A greater flow rate translates to a lower temperature rise. This will help you know the tankless water heater that will meet all your household needs. If you are running two appliances at the same time, you need to get one that produces enough hot water needed. It is, therefore, crucial that you do not need undersize your tankless water heater to save on money.
Another factor that you may need to consider is the limitations that are imposed by your house and the existing plumbing. Homes that have an undersized gas supply need pipes with larger diameters for the delivery of more fuel. Alternatively, the provider will be required to increase supply pressure to your home. The cost may be substantial; updating the gas service will mean a new regulator and meter, and gas repiping needs a lot of labor.
Electronic Ignition System
Also, ensure that the model you intend to buy uses electronic ignition devices. These prevent the continuous fuel consumption of a pilot light that is always on. Most of the newly manufactured propane tankless heaters on the market employ this technology. In this case, you do not have much to worry about.

The vent pipes that are recommended for the tankless water heaters are the large stainless steel. These can sustain very high temperatures. Do not think of trying to reuse those from your old water heater. You may, therefore, need to add in a cost of new venting to your budget of a tankless water heater. Also, propane tankless water heaters have two methods of venting. The code requirements and other specifics of venting may be difficult- professional installation is highly recommended.
The available space for the tankless water heater is also a factor. Depending on the venting method, you need to choose accordingly. The venting methods are power vent and direct vent. The direct vent units require two separate vents- the exhaust and intake. They save on time and space. They are ideal for cramped locations. The power vents require only a single ventilation pipe that is the exhaust.
They need large spaces, unlike the direct vent, for sufficient air into the unit. The location preferred for the power vent units should provide sufficient fresh air that is necessary for the unit. Whichever method you decide to use, there are governing strict codes on where and how venting will be installed. For installation of the tankless water heater, ensure that you hire an experienced local and fully licensed professional.
