Heating Your Home with Radiant Heat

Tuesday, December 17th, 2013


Wouldn’t it be nice if you could somehow have even heat spread out across your home, instead of heat coming out of a vent? There is a way to accomplish this goal, and it is called radiant floor heating. You may have heard of this type of heating but known little about how it works or how it could be of benefit to you. However, this method is gaining in popularity rather quickly.

So what is radiant floor heating? Described in its simplest form, radiant floor heating allows heat to be distributed directly to the floor of a home. This means that heat literally comes up from under the floor in an even fashion. Of course, this is in stark contrast to other heating methods, which may force heat out of vents at different points throughout your home. Homeowners who dislike the uneven nature of heated air flowing from vents will most definitely be intrigued by what radiant floor heating can accomplish. There are three types of radiant heat for floors, which include radiant air floors, electric radiant floors and hot water radiant floors. [1]

A common way for radiant floor heating to work is through piping placed under the floor. This piping brings the heat directly to the rooms and areas where it is needed. The end result is quite surprising for those who have never experienced it before, as the heat provided is far more even than other alternatives.
Not only do most people find radiant floor heating to be more comfortable, but it is also generally seen as a serious energy saver too. [2] Radiant floor heating is more efficient, in part, because heated air is not sent through air ducts. [3] Air ducts represent a major loss of energy efficiency and radiant floor heating bypasses this problem altogether. The end result will be a more efficient home and lower energy bills.

Another significant benefit to radiant floor heating is that the heating system is essentially out of sight and out of the way. This makes it a great option for homeowners who are looking for a clean look.

Adding to the cost benefits of radiant floor heating is the fact that the equipment lasts for a long time and is quite durable. Moreover, radiant floor heating can be integrated into existing systems as well, meaning that you don’t necessarily have to buy a new heating and cooling system.

Experts look on radiant floor heating favorable due to its energy efficiency, but many also feel that it also has some safety benefits as well. Radiant floor heating can contribute to helping wet floors dry faster since the heat is reaching the floors directly. This is something that other forms of heating just can’t accomplish.

If you are looking to get even more out of your heating dollar, it also is important to make sure that you have installed the proper home insulation. ENERGY STAR estimates that up to 20% of heating cost can be saved by adding sealing and insulation.

There are many, diverse benefits to radiant floor heating and, as a result, it is no real surprise that this type of heating is getting more attention. Those looking to make the most out of their energy dollars will want to explore this interesting option that is full of benefits.

Three Grades of Radiant Floor Installation

Wednesday, June 19th, 2013

Radiant heat has long been touted as the what’s what of heating. In many custom homes it is the one thing that the new homeowners are the most proud of. Not only has it become the signature system for ultimate comfort, but it is also a buzz word that many have cashed in on by installing what can only be described as “ghetto radiant”; which has inspired me to bring you this article.

The first of these grades is what I call “ghetto radiant”. This is the use of a traditional hot water tank system to heat the water that is run through the floors.

The worst part is that the water going into the floor is brought back to your water tank and then you are free to use it to wash your dishes or take a shower in. Some authorities permit this so long as the heater is used for both domestic and space heating. However, water heaters used for radiant space heating operate in the temperature range where bacteria, such as Legionella, develop.

To prevent this, the water heater must be run continuously in the range of 140 degrees Fahrenheit or higher, and the radiant system must be cycled periodically, regardless of the need for heating. This operating temperature then forces the use of scald protection valves on the domestic side and mixing valves on the heating side. As is often the case, trying to make the systems more affordable and simpler actually results in more complications and hazards.

Also, this type of radiant heat often relies on fresh air vents in the windows to bring in cold, un-tempered air by installing a timer on a fan in the utility room. Translation: Bare –bones, but to code, ventilation that will lead to the stalest air you have ever tasted. Most of these systems are only one zone, so balancing the in-floor loops and getting even heat throughout the house is a nightmare. My family and I lived in one of these homes for one year while our house was being built; let me just say I feel sorry for the next tenant! Being a heating expert and not being able to do any upgrades also drove me nuts, but I digress.

The second level is the “tank less two step”. This would be similar to the “ghetto”, but instead of a horribly inefficient standard hot water tank, it will come with a high efficiency on-demand water heater, such as a Rinnai. The installation of the floor loops and ventilation may stay the same, so while you gain some efficiency; this type is really a wolf in sheep’s clothing. Tank less water heaters, such as a Rinnai, were meant for heating domestic hot water, not your house. When they are used in this application, the manufacturer cuts all your warranties in half, which isn’t really a great sign.

The third level can be best described as, well, the “Right Way”. I don’t have anything clever for this one; let’s just say it leads to happiness and satisfaction. What you have here is a high efficiency heat source such as a wall mount boiler (not water heater) or heat pump that heats the water for the radiant system and domestic hot water, however, this is a closed loop application so the water in the system never touches the water you shower in! Almost all of these applications are heavily zoned to give you maximum comfort control in every living space of the home. Domestic water is heated in an indestructible in-direct fired water tank (heat exchanger) and Ventilation is provided through a Heat Recovery or Energy Recovery Ventilator so all fresh air coming into the house is both filtered and then heated by stale air leaving the house.

One of the most important decisions you can make is choosing the heating company that will install your system. We are generally always high when it comes to install compared to most of our competitors, but it is not just dollars. We have the highest paid technicians, the highest level of design credentials, the highest level of customer satisfaction, the largest service department and the best guarantee, your 100% satisfaction!

It is very important that when you are shopping for a home or building one with radiant heating, you ask about these three simple things.

  • Heat Source – Is it a water tank, on-demand water heater, boiler or heat pump? What efficiency?
  • Zoning – Single Zone or Multiple Zoning?
  • Ventilation – Window/Wall Ports or HRV/ERV?
