Pros and Cons

There are numerous advantages to picking up a good electric hydronic baseboard heater for your home, but there are also a few disadvantages to consider. We break down these crucial factors in the section below.

Pros of Hydronic Baseboard Heaters

Cost-Efficient

Hydronic baseboard heaters are extremely powerful, and they possess the ability to keep a room warm long after you turn off the thermostat. This is primarily down to the asbestos tube element used in most models that heats up quickly and stays heated for continued durations.

Thanks to this unique feature alone, you have the chance to drop a hefty fraction from your electricity bills as you’ll need to run the heaters for shorter periods every night.

Consistent Heating

Of all the baseboard heater variations currently available, hydronic models can maintain the highest level of consistency while heating a room. 

The use of a sealed heating tube element within each model allows the device to convert almost all the electric power into heat. This, in turn, warms the water or liquid used in the model, and as the water runs through the entire system, it ends up dividing the heat across the house instead of focusing on one spot.

Most hydronic models also have large diameter reservoirs and an asbestos tube element that manages to maximize the volume of heat transfer. This helps maintain the heat of the water in the device for several hours after the thermostat has been switched off.

Quiet Operation

Electric baseboard heaters and forced air systems can be extremely noisy machines that are near-impossible to bear when you’re standing next to them. Electric hydronic models, on the other hand, are much quieter and cleaner in comparison.

This is because this version does not use a fan in its operation, and this component is the biggest culprit when it comes to raising the decibel levels. Thanks to this major change, you can now easily install one of these devices in your bedroom or living room.

Great Build Quality

Most of the best hydronic baseboard heaters are made out of steel components, and this dramatically improves their lifespan and efficiency in the long run. They also come with a front grill that prevents foreign materials from penetrating the internal heater components and causing breakdowns.

You can also pick up these models in a wide range of color options based on your home’s interior.

Safer Than the Alternative

You’ll find that hydronic heaters are far safer than their older cousins. This is thanks to the use of quality design elements such as baked enamel, which helps deter overheating. 

The surface temperature of these models are also lower than pure electric versions, and this helps prevent any accidental burns that may occur with young kids in the house.

Clean

One last significant advantage is the fact that these devices tend to run far cleaner too. You won’t find any airborne particles being emitted out of the machine, and this is an absolute boon for those who have any breathing problems or allergies.

Cons of Hydronic Baseboard Heaters

Heating Time

Hydronic baseboard heaters can take a bit of time to get going, and this is considered a major con for some people. There is a new system that can now be installed to speed up heating times, but the downside is that it will add an extra expense to your project.

FAQs

What Size Hydronic Baseboard Heater Do I Need?

You can determine the size of the required hydronic baseboard heater by examining the size of your home. If you have an average home with R-11 insulation in the walls and R-19 insulation in the ceilings, you’ll need 10 watts per square footage.

Houses with poor insulation need roughly 12.5 watts per square foot, and modern homes with immaculate R-19 and R-38 insulation in the walls and ceilings will only need 7.5 watts of power.

Will Hydronic Baseboard Heaters Freeze?

No, hydronic baseboard heaters don’t freeze as they use a non-toxic transfer fluid that protects itself from freezing in low temperatures.
