Energy Savings - A Benefit of Hydronic Heating Systems

In the previous post we covered the benefit of comfort from a properly designed hydronic system that can help control air and surface temperature at either the whole building or at different zones in the building.

In addition to the benefit of comfort, there are many other benefits available from a properly designed hydronic system and one of them is energy savings. 

Heat loss in structures has a lot to do with the type of heating system installed. As a result, buildings with a radiant heating system usually have lower heating energy use than similar buildings with forced air systems. 

Two factors that contribute to higher energy usage in buildings that do not use a radiant heating system have to do with air pressure and air temperature stratification.

Air pressure

Forced air systems create air pressure changes in each room and the lack of an efficient design system results in heat loss as the heated air goes out through cracks, holes, and other openings as it is pushed by the higher air pressure. Since hydronic systems do not affect room air pressure, they are able to have lower energy usage.

Air Temperature Stratification

Hydronic systems are able to maintain higher temperatures at the bottom of rooms while cooler air can be found at the top of rooms. In contrast, other heating systems result in warm air going to the top of the room and then being lost through the ceiling.

Radiant Floor Heating - Number 2

Image
In the last post we talked a little about the first of five top radiant floor heating systems: Nuheat floor mats. We learned how they are easy to install and contribute to reducing heating costs. Today we will cover a second system. This system is the SunTouch tape mat. You can install this radiant floor mat before you place the final flooring over the top. The SunTouch system comes with everything you need: - the radiant floor heating map - a programmable touchscreen thermostat - sensor wire - installation alarm (a continuity monitor) - and double stick tape To install the map you just have to: - unroll and attach your att - secure the floor sensor - apply thin-set mortar - and install your flooring It is recommended that you plan your layout well. Measure and draw a layout simple plan before installation. The recommended installation temperature is 50 degrees farenheit or 10 degrees celcius.

Hello everyone. Today we have an important question from our audience. The question today is, How can you prevent fires? Seems like a question with a straightforward answer, but let's advance our awareness today!   First of all, preventing a fire is something that has tremendous value, as a fire can spread in devastating ways and put your family in great risk. Some of the most common reasons for fires are: electrical sparks, space heaters, and children playing with matches. In order to prevent fires, tools that you may need are: a CO and Smoke alarm, a combustible gas detection, a carbon monoxide alarm, a fire extinguisher, and batteries. Here are a few tips to help minimize the probabilities of a fire: 1) Never leave your space heater unattended. Also, make sure to leave the space heater at least three feet away from flammable material and on level surface. 2) Do not leave light candles near materials that can ignite. 3) Use a fireplace screen so that sparks can be kep...

Radiant Heating Systems: Installation Cost, Installation Time, Other Considerations

Image
Hello Team, How are you guys doing today? We hope that you all are doing fine during this difficult times. Indeed, we all have been going through much stress and anxiety and uncertainty. In the last few posts, we have been covering details about how radiant heating systems work with different flooring types, form vinyl to concrete to laminate floors. Today, we will cover three more topics regarding radiant heating systems. The first one will be installation costs. Of course, as in many other things in life, a specific answer is impossible to give. The factors to consider are the type of system that you choose for your home and the size of your home. As a general rule, installing your radiant floor heating will range between $10 to $30 per square foot. Again, this depends a lot on the type of system that you want to install and the difficulty of the installation. In addition to this labor part, you will also need to pay an electrician to connect the system to your hour...
