In Floor Heating Systems Hot Water are most efficient?

in floor heating boiler

The efficiency of the heating system depends on the fixed and variable parameters of the components and equipment in its design. The core element is the residential  boiler which heats the water. The supporting elements are the storage tank, system control, supply pipelines, valves, PEX tubing, and the return pipes. Every device plays its part in increasing the design and functional efficiency of the system.

Loss Control

Loss control is one of the key elements that contribute to the increased efficiency of the system. In the modern network it is achieved at various stages from the boiler till the PEX tubing. Insulation, heat diversion, and heat conservation are the three main methods to control the loss.


The insulation materials used in the boiler systems are fiberglass, mineral wool, PU foams, or EPS. They reduce the heat loss to the minimum within the boiler. The R-values of these materials range from 2.8 to 3.8 which are stated to be ideal for preserving the heat. The non-flammable property of these materials makes them highly safe to be used at high temperature zones.

Heat Diversion

In spite of the good insulation, the probability of heat loss still persists in the heating system. Modern boilers use heat trapping and diverting controls which transfer the latent heat loss into the inlet. The best method of utilizing this heat is to install a pre-heating system before the main exchanger. The secondary exchanger can heat the cold water as it enters through the inlet and travels to the main exchanger. It helps in reducing the temperature required to heat the water further and conserves energy.

Heat Conservation

Heat conservation components are installed into the storage tanks, PEX tubes, and within the heater. Specially insulated tanks can preserve the heat for a long time. PEX tubes can preserve heat by controlling the water flow rate. The radiant heating system emits the heat within a specific frequency range. By fine tuning it to preserve the heat when the temperature is ambient, it is possible to prevent the loss of heat. It is done with the help of turn on/off systems at the rooms. The system could be manual or automated which uses sensors to detect the presence of people, room temperature, and the external environment conditions.

Fuel Efficiency

The aim of in floor system is not only to save on energy consumption, but also to utilize the fuel for maximum heating within every cycle. The flow rate and the water pressure play important roles in improving the consumption efficiency.

Highly advanced in floor heating systems can accelerate/decelerate the flow rate according to the internal temperature within each room. They can sense the flow of heat radiation from the in-house objects and the hot spot variation. They can slow the flow rate when the heating requirement is more. By using this technique it is possible to generate more heat without necessarily having to increase the temperature.

The average heating requirement is more during cold seasons. The energy consumption rate also increases due to the external climatic conditions. Radiant floor heating system is efficient as it doesn’t heat the air directly. The thermodynamic radiation (similar to the sun’s rays) penetrates the objects and heats them directly. Hence the air temperature variation makes no difference to its working.

The average heating capacity of the Hydronic (water) system is at least 1.5 times higher than the conventional forced-air heating system. Automated sensors ensure turning on the burner only when the temperature of the outlet water drops below the standard value.

Heating Cycle and Volume

The In-house hot water heating system is scalable in its design. It is due to the hydraulic property of the water due to the flow field it creates. The thermal radiation propagated by the water can be much more than the temperature at which it flows through the PEX pipes.

The frequency of radiation can cause vibrations at specific frequency within the objects in the rooms. Since there is no transmission loss of heat, the vibration can reach the peak level within the shortest time. Hence, the room temperature becomes ambient during the coldest seasons also.

The rate of heat retention within the rooms increases when you use the right kind of insulation to cover the walls and ceilings. Hence, the required frequency of heating is always at the optimum levels.

Hardware Efficiency

The hardware used in the heating system consists of the boiler, pipes, radiant panels, valves, fuel supply units, fuel container, water storage tank, safety devices, etc. The in house heating systems use highly efficient devices and components that are durable and work without any breakdown for many decades. They are highly flexible in design and efficient in performance.

The system can heat any type of floor including the hardwood, tiles, concrete, laminated floor, and the other types with the same efficiency during all the seasons. Control over humidity is the key benefit of the in-floor heating system. It can eliminate most of the bacteria and the germs in the thickly carpeted and densely decorated rooms also. Hence, your family can enjoy hygienic and pure air circulation within the living spaces.

The average distance between the boiler and the radiant panels within each room is important parameter which determines the heating volume requirement. If the boiler is in the basement and the panels are in the second floor, the requirement will be naturally more.

The efficiency of the in floor hot water heating systems have a plus point when it comes to heating volume and frequency. The highly efficient piping system and the pressure pumps can push the water circulation much faster than the conventional air pressure systems. Many of them use Glycol as one of the additives to preserve the water temperature as it flows from the source to the target points.

Maintenance Needs

The average maintenance needs of the in floor heating systems are very low compared to the conventional systems due to the installation of flexible hardware parts and devices. Regular cleaning and lubrication can enhance the lifespan of the system for many decades.

Furnace replacement tricks

Choose the Right Furnace



HVAC INFO  approved heating & cooling loads are done for the jobs that we estimate for you.  This is so we can properly size the new equipment, after all, your comfort and energy costs are at steak.  If your Calgary furnace needs to be repaired furnace is too big it will turn on heat up your home fast and turn off.  This sounds great but actually your floors, rugs, furniture and other things, like walls do not get a chance to warm completely up and then your home gets hot and cold spots as well as hot and cold rooms.



Air Conditioner repairs

If your air conditioner is too big it will turn on, cool things off fast and leave a cold dampness in your home.  This can be very uncomfortable, it makes you feel “clamy”.  If your duct work is too small for the furnace or air conditioner that is put in then there is another set of problems.  In the heating cycle your furnace can get too hot and cycle on and off on the overtemp limit control, a safety device, instead of cycling on and off by the thermostat as your furnace was designed to do.

Air Conditioner replacement

If your air conditioning is working with duct work too small for the cooling capacities put in, the air conditionin coil in the furnace plenum to freeze up and not allow any cooling.These are problems indeed but our industry has come up with problem solvers like the formulas for heating and cooling demands of a home as well as duct work sizing for good air flow and delivery of heating and cooling to your home.  Every good HVAC company will use an ACCA approved problem solving formulas in some form so they can give their customers what is needed. The Nitty-Gritty of HVAC such

What is BTU ?

What is a BTU?  BTU is short for “British Thermal Unit”. The BTU is a way to measure heat.  One BTU is the amount of heat necessary to raise 1 gram of water 1 degree celcius.  There other ways to measure heat like calories but in heating and air conditioning we use the BTU.  So BTU’s can be used to measure a furnace size needed but what gets the heat through the duct work (if you have forced air heating)?  Well the answer to that is a fan, with a motor on it, rated to send a certain amount of air through the heat exchangers of your furnace to get the most heat out so you can get a good heating “efficiency” rating from the furnace.  I

Furnace Rating

n the past somewere rated only as 60% efficient.  This could be looked at as a car’s miles per gallon.  When you look at it, 6 miles per gallon is awful!  The good new is that there are now standards for efficiency in furnaces and split air conditioning systems that work in favor of the homeowner and their pocket book.  The standard was 80% efficient, hmm, that’s still not great but in some cases there is no choice.  In other cases there is great news!  Furnaces are 95% efficient with variable speed motors and 2 and 3 stage heating capabilities.  Now you’re talkin efficiency!  Anyway, in furnaces today fans are rated in “CFM”‘s  which stands for “cubic feet per minute”.

Air Conditioning rating

If you want to put in split air conditioning then you have to not only measure the space in the house along with the building materials, you also have to know the size of the fan in the forced air furnace that is either there or going to be there, then you have to know the size of the duct work.  For right now we’ll talk about the size of the furnace fan.  To generate one ton of cooling through a system it takes 400 cfm of fan capacity.  So if your furnace repair  is rated for 3 tons of air then it can mininally push 1200 cfm of air through the furnace.  Thats not all, this is where duct work sized comes in!  Then you have to measure static pressure through the system (length of duct work formula) then you have to account for filter, register and elbow pressure.  It is alot and so I say, leave it to the professionals.  Hey, thats us!  Anyway, if you have any questions, feel free to call us and we will do our best to answer in detail.
