Types of Patio Heater Parts

The patio parts that need replacement depend on the make and model of the heater.

This list is a general guide for new patio heater owners.

Here is an example of a patio heater and its seventeen components:

Let’s take a closer look at the ten most common patio heater parts that can need replacing.

Heater Regulator

To maintain a stable and uniform temperature, you need these components for your patio heaters.

Due to the height of many patio heater models, heat regulators for patio heaters require longer hoses.

The hose connects the heater element to the propane tank with a regulator.

Glass Tube

If your patio heater is ever knocked over by wind, this piece is most likely to be damaged.

Glass tubes on patio heaters are popular on modern models. They contain the gas-fueled flame, giving it a straight, vertical appearance.


Burners on patio heaters ignite the fuel source, usually propane or natural gas.

The burner also helps to direct the flames into a perforated metal screen and then radiate that heat from the screen’s surface.

The heat is radiated in a circular pattern around the patio heater to deliver surround heating.


When the thermocouple detects heat, it sends a signal to the gas valve to open and allow gas to flow to the burner.

When a patio heater fails to turn on, often a weak or non-functioning pilot is caused by a faulty thermocouple.

Pilot Assembly

The pilot assembly’s function is to maintain the patio heater’s flame by sending an electric signal to the gas valve through a sensor.

It signals the valve to stay open.


A thermostat on a patio heater controls whether the heating is on or off.

It also regulates the flow of the fuel source, propane or natural gas, which in turn helps maintain the overall temperature.

Failure Safety Control Valve Kit

These control how patio heaters will operate when there is a loss of power or signal. This helps protect the patio heater, typically in emergencies.

If the fuel source is lost during your patio heater operation, the safety control valve will turn off the pilot light.

When issues arrive with safety control valves, you’ll notice your patio heater turning off even with a steady flame.

Regulator Hose Set

These are the hoses that connect your propane tank to the patio heater.

While they are typically made to last, outdoor small animals can cause damage or they can become damaged accidentally.

Wear and tear over time can also cause these hoses to lose their airtight connection causing the fuel source to leak.

Pilot Feed Tube

Pilot feed tubes connect your pilot flame to the central control valve. Issues with these will cause problems with the pilot light that can lead to an inability to start the patio heater.

These tubes can become clogged or broken over time but are fairly easy to repair or replace.

Spark Ignition

These ignite the pilot light to allow the fuel to catch and begin burning at the desired intensity.

Issues with spark ignitions will cause difficulty in getting your patio heater started.

Depending on the model, there may be manual ways around this, such as using a BBQ lighter. However, sometimes, the model depends on the spark ignition solely.

The Different Types of Patio Heaters

Freestanding Patio Heaters

When looking at available patio heaters, freestanding models are popular.

Freestanding heaters deliver a great experience and are pretty straightforward to use.

In most instances, we don’t want to install a patio heater permanently.

Being able to easily move a patio heater based on weather and upgrading it later is convenient.

We recommend purchasing a freestanding patio heater for added versatility.

You won’t need to use any mounting brackets to secure the patio heater and start using it.

They bring along portable propane tanks to provide you with the desired functionality.

The freestanding patio heaters you purchase will contain their controls.

You can take better control over the heater according to your preferences.

There are four distinct types of freestanding patio heaters available for purchase to use in outdoor settings.

Quartz Tube-Type Patio Heaters

If you want to elevate the appearance of your outdoor space, choose these patio heaters. They can create the perfect ambiance.

They are also an excellent option for smaller spaces.

However, patio heaters are not very efficient and do not perform well in strong winds.

Mushroom-Type Patio Heaters

The mushroom-type patio heaters come in various sizes and add an aesthetically pleasing look to your outdoor space.

These are the perfect options available for any small space.

However, the mushroom-type patio heaters are not the most efficient and they only provide little resistance against wind.

Bromic Tungsten Smart-Heat Patio Heaters

These patio heaters are equipped with advanced features and parts, giving them a modern and chic appearance.

These patio heaters offer the most efficient option and excellent wind resistance. You can get directional heating out of them with minimum trouble.

In order to purchase this type of patio heater, a substantial amount of money will need to be spent.

Table-Style Patio Heaters

If you have enough space, consider purchasing a table-style patio heater.

Table-style patio heaters have a modern design and come equipped with a safety cutoff feature. These patio heaters can be used as tables when not in use.

This patio heater provides useful table space but does not heat the upper air. They are not the most wind-resistant and efficient patio heaters you can buy.

Wall-Mounted Patio Heaters 

A wall-mounted patio heater is ideal for saving space, in addition to freestanding ones. Mounting the patio heater away from traffic creates more outdoor space.

Wall-mounted patio heaters are the most efficient and provide better control options. It is possible to have a less intrusive experience with them.

You should be aware that wall-mounted patio heaters come at a higher cost compared to other options.

However, the returns justify the expense, even though it means giving up portability.

If you don’t have any plans to move the patio heater, you can go ahead with this option.

Remember to review the patio heater parts with any style for future repair costs.

Different Materials Used for the Manufacturing of Patio Heaters

Manufacturing materials commonly used for patio heaters.

Stainless steel patio heaters are durable and weather-resistant, but their coating can be easily scratched or damaged. They are available in various color options.

Some patio heater parts may need replacing; this list covers the most common ones..

Whether it’s an accident or wear and tear, appliances don’t last forever.
