Difference Between a Water Heater, Furnace, and Boiler

Few people don’t know the difference between a water heater, furnace, and boiler. Although they deliver close to similar results, there are some major differences in how they do it.

And since it’s winter, one can’t do without having hot water. Therefore, if even one appliance stops working, you need to call an HVAC specialist immediately. But how would you know which appliance is giving you trouble?

Let’s look into HVAC 101 to know the basic difference between a water heater, furnace, and boiler.

Main Difference Between Water Heater, Furnace, And Boiler

Water Heater

So let’s start with a water heater. This device’s function is to provide hot water to you whenever you want. However, it’s not an HVAC specialist’s job to handle a water heater as it is part of your home’s plumbing system. So, if your water heater breaks down, hire local water heater repair services. That’s because a water heater can explode if left unrepaired.


A furnace’s job is to keep the house warm and toasty. However, to do this job, the furnace heats the air and transfers the warm air all around the house. A furnace doesn’t use water, unlike boilers. Though both the boiler and furnace do the same thing, they are not interchangeable. Therefore, you need to mention specifically to the professional what’s not working at your place.


When it comes to boilers, they heat the water and also warm the surroundings. What they do is that it warms the water and sends this hot water all around the house. This keeps the house warm and comfortable. But the difference between boiler and heater is that the boiler also warms the home, therefore falls under the HVAC system.

Which Is Better For Home? Water Heater, Furnace, Or Boiler

Water heaters are devices that simply give you heat water. They won’t keep your house warm. Whereas boilers may offer hot water while also heating your home with heated water. Heat pumps and furnaces warm the air and spread it throughout your home in a colder atmosphere. As mentioned above there are several pros and cons to each of them.

You need to consider all the factors, like installation costs, the total energy going to be used, and any other preferences if any homeowner wants to install. If you are busy and cannot complete the schedule some professionals can help you in these conditions.

They are well trained with professional Hi-tech equipment to cover up all the mistakes done before. It makes sense to call them instead of trying DIY. If you are also a local then the services are available all 24 hours.
