How Do Propane Tankless Water Heaters Work
Compared to tank-style water heaters, propane tankless water heaters only heat up and provide hot water on your demand. It has the following parts:
- Flow sensor
- Control panel
- Gas valve
- Heat exchanger
- Mixing valve
- Water valve
- Isolation valve
- Temperature sensor
When you turn on the tap or use a device that requires hot water, cold water then starts flowing through the system. The model’s flow sensor detects running water and then signals the control panel to start the liquid heating process.
In gas-powered appliances like propane on demand water heaters, the control panel subsequently activates both the fan and gas valve. The fan lets the outside air enter while the gas valve injects the fuel. The control panel also ignites the burner to heat it.
The heat exchanger component then absorbs the resulting heat from the flames and transmits it to the water passing through the water heater’s tubing. A mixing valve tempers the water’s temperature before it exits the exchanger.
The water heater’s temperature sensor then checks if the hot water follows the chosen setting. If not, the control panel adjusts the gas, mixing, and water valves accordingly.
Once the temperature is alright, the now hot water exits the machine and is ready for use.
Sealed vents then dispose of the exhaust gases. It is also responsible for providing air to the burner to kickstart combustion. However, outdoor propane tankless water heaters do not need any vents.
Propane Tankless Water Heater Buying Guide
Tankless water heaters are more energy-efficient and cost-effective compared to tank-style devices. Without the tank, these products are also smaller and more compact, making them ideal for smaller homes or those with small spaces.
Not only that but because of how they work, they seemingly provide an endless amount of hot water anytime, anywhere.
Because of these benefits, tankless water heaters are popular. However, choosing and purchasing can be difficult. But you do not have to worry since this buying guide will lay down the factors you need to consider in a tankless water heater.
Flow rates are measured in gallons per minute and indicate the amount of water the device can provide. This factor is crucial since having a low flow rate would mean difficulties in meeting your home’s demands, while a high flow rate would entail unnecessary costs.
To determine the flow rate you need, list down all the appliances or fixtures that your household needs during peak demand. After, you need to calculate each appliance flow rate and add it all up to get the total.
Determining the temperature rise is essential since it affects the amount of energy the water heater needs to use.
To get the temperature rise, deduct the groundwater temperature from the desired water temperature. You would want your heated water to be about 49ºC or 120ºF or somewhere along that range.
In most households, incoming waters usually have a temperature of 10ºC or 50ºF. However, this can change depending on your region and its climate.
Take note: the more significant the difference between the groundwater temperature and desired temperature is, the more energy the water heater will use.
Tankless water heaters with a recirculation function enable the water heater to send the excess hot water to the unit via a pump. Products with recirculation features quickly provide hot water as to the standard models.
Tankless water heaters are greatly affected by scale deposits as this can slow down their flow rate. As such, you should purchase a model equipped with anti-scale devices. These devices slow downscale build-up by swirling the water.
Digital displays make it more convenient for the user to monitor temperature levels and customize the heater’s operation.
Indoor vs. Outdoor Models
You can install indoor propane tankless water heaters inside your home. It protects them against weather changes and other elemental factors.
However, indoor products require a particular type of ventilation. There needs to be a vent attached near a drain to deal with the constant condensation. You also need to install ventilation piping to direct exhaust gas outside.
Outdoor propane tankless water heaters do not need ventilation piping since it is unnecessary to direct exhaust gases. Moreover, these heaters are made of sturdier materials because they can withstand various weather conditions.
However, outdoor appliances may require constant maintenance check-ups. You will have to be vigilant in finding defects and damages and quickly repair them.
Frequently Asked Questions (FAQs)
Who makes the best propane tankless water heater?
Well-known brands have consumer trust and confidence, assuring them quality and effectiveness.
According to tankless water heater propane reviews, here are some of the most popular brands in the industry:
- Foruee Perfect Comfort for Family
What size tankless water heater do I need?
Determining the size of your tankless water heater is crucial. If it is too small, then the product will not meet your household’s demands. A too-large one will add on unnecessary costs.
The size depends on how often you need to use hot water, measured in the flow rate and expressed in gallons per minute (GPM). You can tell a unit’s flow rate by looking at its British Thermal Unit (BTU) input and efficiency measures.
Flow rates range from 1.2 GPM to 6 GPM. Generally, the higher the BTU rating, the higher is the flow rate.
For example, a unit with 31,000 BTU delivers a 1.2 GPM, while another model with a 190,000 BTU gives a 5.7 GPM.
Aside from flow rates, the water heater’s size also depends on the energy it uses. The energy ratings vary from 78% to 87%. Generally, the higher the rating, the more energy-efficient the unit will be.
How big of a propane tank do I need for a tankless water heater?
The correct propane tank size depends on the amount of water you use and how often you use it. As such, it will depend on the tankless water heater flow rate and BTU.
Moreover, it will also depend on the temperature rise, which is the energy needed to heat the ground temperature to your desired temperature. This factor will depend on your region and its climate. If the ground temperature is too cool, the device requires more energy to heat the liquid.
A 100-pound propane gas tank has 2,300,000 BTUs, heating water for various point sources and appliances. A 15-gallon tank can meet a two-member household hot water needs.
On the other hand, a 25-gallon tank per month can suffice for a three to four-member family.
A household of more than four members requires 35 to 40-gallons of propane to meet its hot water needs.
How to install a propane tankless water heater?
Since tankless water heaters are more compact, you might think installing them is easy. However, many forget that these water heaters require special ventilations to deal with condensation and exhaust gases.
As such, installing one should be delegated to a professional since you will need to establish leak-free connections with the water, vents, and gas. The installation process also depends on the type of gas tankless water heaters you have.
Non-condensing systems are cheaper than the others, but they are also more expensive to install. Due to their mechanism, they need a more complex and costly venting system.
On the other hand, condensing tankless water heaters is the opposite. They require less installation costs since their control panel extracts and absorbs heat before traveling through the venting.
Outdoor models are cheaper to purchase and install since they do not require any venting system. However, these systems are not always suitable for most households.
Can a propane tankless water heater be converted to natural gas?
Yes, some tankless water heaters allow users to convert from using propane gas to natural gas. Changing the tankless water heater fuel source is usually part of a gas utility program.
Conversion is a delicate and complicated process due to the differences in pressure between propane and natural gas. As such, you must find the correct gas valve and a burner that matches the type of gas you desire to use.
First, you will need to remove the manifold burner and install the correct one. You also need to convert the gas control valve to the natural gas set by twisting the cap. After, place a sticker near the rating tape to indicate the gas type used.
However, it is best to perform the conversion on an appropriate unit and preferably by a licensed gas technician. Otherwise, you risk damaging the tankless water heater and exposing yourself to danger.
Is propane cheaper than electric?
Yes, propane is cheaper than electric. According to the US Department of Energy, propane heaters only cost one-third of the price compared to electrical heating systems.
For example, a 2,500-watt heater running for 8 hours on electricity would cost $2, while it only costs $1.60 on propane models.
According to a tankless propane water heater review, propane and gas-powered units are more energy-efficient than their electric counterparts, enabling them to cut back on household costs. Moreover, they are also quicker and provide more warmth.
Propane water heaters are also more durable, having an average lifespan of 20 years. On the other hand, most electric water heaters only last for 5 to 10 years.
With too many options to choose from – all vying to be the best propane tankless water heater, you have to exert a little more time and lots of effort to shop wisely.
Remember that every brand has its pros and cons, and you have your unique demands and preferences when it comes to hot water. You have to factor in considerations, and you can have an easier time deciding by not being impulsive and investing time to go through unbiased reviews and feedback.
Besides getting hot water, you have to be satisfied with your purchase’s overall performance, functionality, and longevity.
