Hot Water Heaters

A water heater gives you a constant stream of heated water to multiple fixtures of water throughout the building, and it is one of the central Home Appliances for any residential house. That’s why these types of heaters are known as one of the best water heaters for home.

The interesting fact about them is that each type has the same function but in different manners. This fact will give them a plus point over the other heater. 

Types of Water Heaters

1. Electric Water Heater

This is the first type of water heaters that are available to purchase. These heaters technically provide you with better energy efficiency than gas water heaters. They have less upfront cost and will only produce hot water slowly.

The number of households is increasing yearly, and these water heaters will likely outnumber gas water heaters. These heaters use electric heating elements or equipment to heat water.  

Electric water heaters normally contain two heating elements as well. They contain two thermostats to handle or manage every heating element.


  • Better than gas water heaters.
  • Contains two thermostats


  • These heaters don’t heat water quickly.

2. Gas Water Heater

Gas water heaters are one of the famous fuel types in America, and they are currently used in 50% of homes. These heaters use gas burners to heat the water and release toxic fumes through one of these three ventilation systems. Direct vent, power vent, and atmosphere vent.

They heat water quickly, and you can use these heaters whether there is a power outage or not if you have a pilot light rather than an electric ignition. You know that gas is cheaper than electricity but the price of water heaters gas is more than water heaters.


  • Cheaper to operate than electric water heaters
  • Recover much more quickly


  • Often cost more than electric water heaters upfront
  • Not all homes have gas; might need to be added

Baseboard heaters

These heaters are generally a versatile and powerful option for home heating. These heaters are currently the primary, supplement, and zoned heat source in small buildings, large rooms, and individual rooms.

They generate a specific amount of heat without needing an expensive central heating system, making them a famous choice in older homes. They have an affordable price, and they run quietly without any noise. Their lifespan is above 20 years with less maintenance.

Types of baseboard heaters

Electric Baseboard Heaters

These heaters are an affordable option for heating one room to another. They are not very expensive because no ducts are needed. Unfortunately, they are not efficient, just like the central heating system. The room is heated through the radiating heat from baseboard heaters, which takes more than 1 hour to give you the desired temperature.

These heaters provide heating by using electric resistance. The air is heated in the heating unit through cables and then pushed out. The cold air will enter the heating unit, and hot air will be pushed out. This is one of the most used baseboard heaters electric in all around the world now.


  • Affordable
  • No ducts needed


  • Not as efficient as a central heating system
  • Takes time to heat a room

Hydronic Baseboard Heaters

Hydronic baseboard heaters use water or oil sealed in their system to heat the air and keep it warm long after the thermostat turns the system off. However, these heaters cost you much more than their electric counterparts, and they have few options available. They take time to set the desired temperature in the room. You can also search for cadet baseboard heaters, which are a type of baseboard heater.


  • Water or oil stays warm long after the thermostat turns the system off
  • More energy-efficient than electric heaters


  • Cost much more than electric heaters
  • Fewer options available
cadet baseboard heaters

How do baseboard heaters work?

A heating element in a baseboard heater uses electricity to warm the air through convection. Since air rises when it gets warmer, the room has a constant flow of warm air. A thermometer controls the process and lets the temperature be adjusted.

Heaters for Homes

When the temperature drops from its desired value, it is easy to locate yourself cracking up the thermostat to keep your home hot. If you choose the right type of home heater, then it will save your energy and ease the burden of your thermostat.

All the heating systems share one common goal: transferring heat to the living spaces to keep the environment toasty and comfortable. Few homes have more than one heater because they have additional room and a basement. So, let’s look at some of the best home heaters.

Types of heaters for homes


One of the common types of home heating systems is forced air distribution systems. The reason is that they use a furnace with a blower fan, which delivers heated, conditioned air to the house’s multiple rooms through the network of ducts.

The forced air systems share a similar blower and ductwork, just like the air conditioner, and that’s why they can also be used in the summer months. The fuel sources of these furnace heaters are propane, natural gas, oil, and electricity.


  • They combine both heating and cooling capabilities in one single system.


  • Gas furnace heaters might create a risk of fires, carbon monoxide poisoning, and explosions.

Boiler Heaters

Radiators and boiler heaters are more common in flats and old homes. They contain a central heater that sends water or steam to the radiators around the house through pipes. This method works best for the house’s cooling and heating areas one by one. Unfortunately, it is not good for simultaneously heating large areas of the house. The fuel sources of boiler heaters are biodiesel blends, natural gas, electricity, fuel oil, and propane.


  • Compared to other heating systems, these heaters will give you a smooth and comfortable heat that will not dry out the air.


  • According to HAVC, boiler home heaters are not combined with air conditioning for a year.

These are two popular types of heaters in homes that most homeowners use right now.

Walls Heaters

A wall heater is a heating unit installed or attached directly to the wall. These heaters are designed to save valuable floor space and are generally used to heat small areas like rooms, offices, and compact living spaces. You don’t have to extend the HVAC system if you installed these wall heaters in your home. 

When you are installing the wall-mounted heaters, then the process is simple. You must attach them directly to the wall and their circuit to the electric panel. These heaters are different from other portable heaters because portable heaters are generally plugged into the wall outlet. In the case of wall heaters, no wires will trip on. Let’s take a look at some of the best wall heaters.

Types of Wall Heaters

Wall Heaters Gas

These heaters are large and they are complex. They need an installation professional, so that you can contact our TheFusionFeed expert team. The cost of gas wall heaters is higher as they are more affordable to run.

Wall Heaters Gas

Wall heaters Electric

The initial price of an electric wall heater is less, but you have to pay more money to operate them month after month as compared to gas heaters. These electric heaters are long-term and durable, lasting 20 to 30 years. Maintaining them and not combusting the fuel onsite is easy, eliminating the risk of carbon monoxide or gas leaks. This is one of the famous types of electric wall heaters.

Types of tankless water heaters


You should have considered a tankless water heater because you don’t need any air pipes and venting materials. After all, these heaters take heat from the exhaust before sending it to the venting system.

The tankless water heater uses the heat from the ground to heat water in another way. Condensing water heaters are more expensive to purchase but have low installation and maintenance costs. In addition, they provide you with higher energy efficiency so that the cost of the device will be lower in the long run.


  • Energy-efficient
  • Less carbon footprint
  • Low Cost of maintenance


  • More expensive cost of purchase
  • Require more maintenance
Condensing Tankless water heaters


These types of tankless water heaters use heat exchangers to heat the water and then vent the exhaust outdoors. They require stainless steel flue pipes to withstand the exhaust heat, which enhances the installation cost.

The installation cost of these heaters is more than that of condensing tankless water heaters, but they have a low purchase cost.


  • Less expensive cost of purchase
  • Require less maintenance


  • Short lifespan
  • Less energy-efficient
  • High carbon footprints
