When cold winter days hit, you can, as a homeowner, almost expect frozen pipes, high electricity bills, and more home maintenance expenses.

To prevent pipes from freezing or always having your main heating source on the highest power settings, crawl space heaters are a great option.

They will reduce your electricity bills, so you won’t need to use the main heating source so much anymore. Also, you won’t have to deal with frozen pipes.

Let’s reveal the top 5 picks on the market, and then we’ll cover more details later in the article (or you can watch the video below with all five reviews).

What To Consider Before Buying a Crawl Space Heater

  • Budget – Installing crawl space heating isn’t cheap; you have to calculate the cost of running it in winter.
  • Safety – Non-electric crawl space heaters are more dangerous than electric ones, so always have a thermostat to check the heater’s temperature.
  • Size – Measure the volume of your crawl space in cubic feet before purchasing. You want to make sure that it will cover enough area and that it will warm your home.
  • Maintenance – You’ll need to maintain your crawl space heater often to prevent any fire risk and take care of it on time.

This Dr.Heater model will operate at 6000W at the highest power settings and at 3000W at the lower power settings.

Although it may not look like it, this model is a wall-mounted heater.

What I love about it is its adjustable thermostat, so you can always set up your desired temperature.

The airflow is excellent, and it’s surprising how quiet it is. Considering it has 25,000 BTU, it can cover a larger crawl space.

Another great thing about it is that it doesn’t overheat, and it doesn’t get hot behind the unit.

2. With Thermostat: Fahrenheat FBE15002

Our Pick

This Fahrenheat model has a different design than most heaters – it’s long and thin, making it suitable for any space.

Because of this design, it’s very portable, and you can move it around every room or space in your house.

It’s even safer than most models because it’s fanless, making it a lot quieter.

Talking about safety, it even has overheating protection, so when the heater reaches a specific temperature – it will automatically shut off.

This is a baseboard heater, so if you’re not a fan of it – you should check out baseboard heater alternatives.

It uses convection heat that prevents allergens and bacteria from blowing around the room.

3. Budget-Friendly: Cadet F Series 36″

If you’re on a tight budget – this is the perfect crawl space heater.

What’s impressive (considering the price) is that it is a UL-listed heater. The design is practical, and you won’t have to worry about parts falling out or needing maintenance.

The installation is super easy as you just need to plug it into the outlet, and it will start working.

Although you can use it in a crawl space, this heater performs best when placed below the window.

It has a high-temperature shutoff, so it’s very safe.

4. Powerful: Dura Heat EUH4000

If you want to heat your crawl space, this heater will do the job without questions.

It’s very powerful, so please use it only for a larger area.

When you turn it on, expect instant heating because it has 13,000 BTUs, which is pretty powerful.

Although it’s a bit heavier than other models, it has a built-in handle, so you can move it whenever you want.

As with other models on this list, this model also has overheating protection.

5. Most Durable: DIMPLEX DGWH4031G

This model is built from the highest quality material, so there’s no doubt it will last at least 5-10 years.

Don’t let the size fool you; it has a 4,000W operation, which is considered solid.

The reason behind its durability is that it’s made from heavy gauge steel treated with an epoxy powder-coated finish.

You can mount it on the ceiling or on the wall or even keep it on the floor if you want.

This is considered a garage heater, but you can use it in your crawl space.

It has a built-in thermostat and automatic overheat protection, so it’s suitable for almost any area.

How To Stop Your Pipes from Freezing in the Crawl Space?

Heat pipes more often

You should heat pipes more often to prevent pipes from freezing in the winter.

My advice is to wrap them using UL-certified heat tape with a thermostat – this will prevent any danger of overheating.

Filter faucet

You should filter cold and warm water in your bathroom and kitchen faucets.

This prevents water from building up pressure in the pipes, one of the most common reasons they freeze.

Washing machine

You should put your washing machine in the warmest settings and repeatedly turn on the filling cycle to allow water to go through the pipes.

You can turn on the filling cycle for a few minutes, enough for water to come through.

Close space foundation

If you have a crawl space (which I assume you do), close your foundation entirely.

It’s important that you don’t have any gaps or leaks; even if you have – use expanding foam to close them.

Eventually, you should watch this video to ensure your pipes won’t freeze during cold days.
