Installing heat tape on water pipes is a simple yet effective way to prevent frozen damage. The key is to choose the right type of heat tape for your pipes.
Heat tape comes in different types, including self-regulating, thermostatically controlled, and constant wattage. Each type has its own unique features and benefits.
For example, self-regulating heat tape adjusts its heat output based on the temperature, making it a great choice for pipes that are exposed to varying temperatures.

What You Need to Know
Heat tape is a type of electrical heating element specifically designed for outdoor use on water pipes.
You'll want to choose a heat tape that's suitable for your climate and the temperature range you'll be using it in.
It's essential to wrap the heat tape around the pipe in the opposite direction of the water flow to ensure even heat distribution.
The heat tape should be wrapped tightly around the pipe, but not so tightly that it restricts water flow.
You'll need to determine the correct wattage for your heat tape based on the length of your pipe and the temperature you want to maintain.

Choosing the Right Heat Tape
Choosing the right heat tape is crucial to ensure your water pipes stay safe and functional during freezing temperatures. You can find heat tape in lengths from 6 feet to 300 feet, and from 30 watts to 500 watts.
Some heat tapes are specifically designed for galvanized or copper pipes, while others can be used with either metal or plastic. It's essential to verify the product's specifications before making a purchase. The experts at SupplyHouse.com are always available to help homeowners make the right choice.
Consider a heat tape kit, which typically comes with plugs already attached, making it easier to install and ensuring a proper connection. The kits are available in various lengths, from 3 feet to 100 feet. Don't forget to measure your pipes before buying to ensure you have enough tape to complete the job.
Tips for Buying
Choosing the right heat tape can be overwhelming, but with a few simple tips, you'll be on your way to a successful installation. Consider purchasing a heat tape kit, which usually comes with pre-attached plugs and is available in various lengths.
A heat tape kit can be a great option for beginners, as it eliminates the hassle of attaching plugs to raw cable. These kits are typically available in lengths ranging from 3 to 100 feet.
Before buying heat tape, take measurements of your pipes to ensure you have enough tape to complete the job. Don't forget to account for any spiral wrapping, which may require longer tape lengths.
Most heat tapes are approved for use on either plastic or metal water lines, but it's essential to verify this before making a purchase. Be sure to read the specifications to ensure the product meets your needs.
Some heat tapes come with features like power indicator lights or built-in thermostats, so consider what features are essential for your project.

Self-Regulating
Self-Regulating heat tape is a great option for wrapping around pipes. It automatically varies its heat output according to changes in the surrounding temperature.
You can buy self-regulating heat tape by the roll or even by the foot in many hardware and home improvement stores. It's a convenient and flexible solution for custom fit applications.
Self-regulating heat tape can be cut to any length for a custom fit, or it can be purchased in kit form in a variety of lengths. This makes it easy to find the right size for your pipes.
The cable emits virtually no heat when temperatures are above freezing, and it increases levels of heat as temperatures drop. This means you don't have to worry about overheating your pipes during warmer months.
To use self-regulating heat tape, you'll need a connection kit with an end plug, as well as an accessible outlet to plug in the cable. If you buy the tape in a kit form at a specific length, the plug is generally already attached.
Self-regulating heat tape uses a temperature sensor to combat freezing ambient temperatures. This means it can adapt to changing temperatures and provide the right amount of heat to prevent freezing.

Choosing the Right
Choosing the Right Heat Tape is crucial to ensure it serves its purpose effectively. You can find heat tape in lengths from 6 feet to 300 feet, and from 30 watts to 500 watts.
The terms "heat tape" and "heat cable" are often used interchangeably, but there are flexible varieties referred to as tape and stiffer cable-like varieties. Both can be suitable for wrapping around pipes.
Consider a heat tape kit if this is your first time installing heat tape. Kits typically come in just about any length you might need, from 3 feet to 100 feet, with plugs already attached for a proper connection.
Before buying, take measurements of your pipes to ensure you have enough tape to complete your job. Remember that if you plan to wrap the tape in a spiral fashion around the pipe, the length of the tape will need to be considerably longer than the pipe itself.
Here are some key factors to consider when selecting a heat tape:
- Length: Choose a tape that matches your pipe length, with a minimum of 600 mm shorter than the pipe.
- Voltage: Select a tape with the right voltage for your application.
- Type: Consider self-regulating heat tape, which can be cut to any length and emits virtually no heat when temperatures are above freezing.
Self-regulating heat tape can be purchased in kit form or by the roll, and it's essential to have a connection kit with an end plug and an accessible outlet to plug in the cable.
Installation
To install heat tape on water pipes, you'll want to follow some key steps. First, make sure the area on and around the pipe is clear of sharp edges and combustible materials to minimize the risk of damage to the cable and adjacent areas.
You'll also want to ensure that the pipe is free of any debris or obstructions. If you're applying the heat tape to a plastic pipe, it's a good idea to wrap the pipe with aluminum foil first. This will help distribute the heat from the heating cable uniformly around the pipe.
When preparing the power supply, be sure to remove the two-pin plug in the UK and make the connection to the mains in accordance with current regulations and by a qualified person. The cable must be earthed.
The thermostat should be placed tightly against the pipe and secured with PVC electrical tape. It's essential to position the thermostat on the coldest end of the pipe, as this will give it the most accurate reading.

You can lay the heating cable on the pipe and fasten it to the pipe at approximately 600 mm intervals using good quality PVC electrical tape. For pipe freeze protection under extremely cold conditions, or to minimize energy consumption, it's recommended to add insulation to the pipe over the heating cable.
Here are some guidelines for insulating the pipe and heating cable:
- For mineral wool insulation, a maximum of 13 mm of insulation may be applied over the heating cable.
- For foamed insulation, a maximum of 13 mm of insulation may be applied over the heating cable.
- A waterproof overwrap must be applied to the insulation to prevent moisture penetration for mineral wool insulation.
- Waterproofing is usually not required for foamed insulation.
Finally, once the cold season begins, plug the power cord into an appropriate receptacle.
