Heat link In-floor Hydronic Radiant Heating

The Reason of HVAC FOR LIFE INC. Consumers choose Heat Link Hydronic radiant floor heating is comfort.
The system eliminates chilly drafts. There's no need for fans to move air around.

In today's new home designs, Hydronic radiant floor heating makes even more sense.
Rooms (bathrooms included) are larger, with higher ceilings and lots of tile and other cold surfaces.
With forced-air and radiator heating, these spaces generally feel cold. That's not a problem with radiant floor heating; even the hard surfaces will feel warm to the touch.

The system allows great flexibility when it comes to furniture arrangement, too. With forced-air or radiators, occupants must strategically place their furniture to accommodate grills or radiators. With radiant floor heating, furniture can go anywhere because there are no grills or radiators.

The Basics

At its most basic, Hydronic radiant floor heating involves heating a structure by pumping warm water though specially designed tubing laid under or within the floor. The heat in these tubes radiates to the surface and rises evenly throughout the room above. The surface itself stays comfortably warm to the touch. This tremendously efficient heat transfer results in even and consistent heating.

Warm air rises, of course, and collects near the ceiling. In a home heated by convection, ceilings are always warmer than floors. With radiant floor heat, the opposite is true. The floor is warm, and so is the air up to the height sensed by the occupants. Thus, people within the space feel much more comfortable at lower temperature settings because the heat is coming from the floor.

Heat Link PEX tubing which delivers the heat is laid on the subfloor and covered with a flow able lightweight concrete. It can also be installed in the lower level concrete floor, or underneath the joist space-which is called a 'dry' or 'staple-up' installation.
The system allows any floor surface to be placed above it, including carpeting, ceramic tile, vinyl flooring, and wood.

Comfortable & Efficient

The surface temperature of the floor is designed to be no higher than 88 degrees F (31 degrees C), so it's always comfortable to walk on. HeatLink operates at the lowest possible water temperature to heat the structure. This level provides the most efficient transfer of energy. There are no wide temperature variations that you experience with forced air or radiator systems. It's also quiet! There are no noisy fans or radiator expansion noises to contend with, just quiet comfort. Energy efficiency is one of the system's strong points because the system delivers heat where it's needed, with little waste. A thermostat can be put in every room of the house, and unoccupied rooms can be set back to save energy.

Consumer frequently asked question:

in floor radiant heating Toronto

How long will it last?
PEX pipe will last as long as the structure.
PEX pipe has been in use for over twenty years in Europe and life
Cycle testing has demonstrated that PEX can last in excess of seventy years.
PEX is an inert material, virtually indestructible by common elements.
Heat Link warranties its tubing for 25 years and includes consequential damage protection of 10 ten years.

What happens if a pipe breaks?
Heat Link has a repair coupling that is used to repair the damage.
Damage is very rare, but when it happens it usually happens during installation.
The tubing is still exposed and repairs are made quickly and easily.


Can I air condition?
Yes! There are several choices; conventional separate system, ductless mini splits, and high velocity.
Essentially you would will end up with two systems, an air conditioning system and a heating system.
There are cost and performance benefits to all three choices.

We favor high velocity because; it uses very small air supplies and a central return.

No large grilles, registers and noisy fans!

How much does it cost?
Costs will vary by job and design.
Most of the difference in cost from basic to deluxe is in the control options.
A good example would be an eight room two story house,
you could have two thermostats, one for each floor or eight thermostats one for each room.

Do I have to do the complete house?
No! Today many people choose to do the "tough to heat" rooms or areas.
Good examples are basements, garages, high ceiling areas, bathrooms and other tile areas.

Additionally, this strategy keeps the costs down and still gives you the comfort of radiant heating.

What runs through the pipes?
Water! Most systems are designed to use water, but in some cases glycol is used.
Glycol would be chosen if snow melting was being done or for freeze protection.

Does it heat up fast?
Radiant floor heating systems heat up and cool down slow resulting in very even heating.
Once up to temperature the system will stay within one degree of the thermostats set point.

What kind of boiler do I need?
Radiant systems can use a variety of boilers according to local code authorities.

Radiant floor heating systems are powered by a boiler or a special water heater therefore no furnace is needed. Often, the floor heating system can be combined with high-velocity air conditioning, and a potable hot water delivery system for cooking, bathing and laundry.

Many homes today have one or more vaulted ceilings. With forced-air or radiator systems, these larger open areas require ceiling fans to blow air up or down, depending on the season. But with a radiant floor system, warm air is already right where you want it.

Think of it this way: when you're sitting down to watch TV, if you have a forced-air or radiator system, often you must turn the heat up to be comfortable; with radiant heat, you can actually turn it DOWN because you're closer to the floor, which is the source of heat.

Its Under Stat link Control determines the success of a Hydronic system, and Heat Link's integrated Stat Link control system and flow-balancing manifold establishes that control. Balancing of a radiant system is critical, especially when you have a complex layout, with different zones and varying loop lengths. The ability to adjust and balance each loop is vital to the total system performance. Heat Link's system is engineered to control and operate every component independently. When the system is in use, the Stat Link control system is the 'brain' of the various room thermostats. By simply adding a Stat Link setback module you can completely automate your entire system.

In The Zone, A zone is an area of thermostatic temperature control, which may consist of a single room, a single level, or other designation. A typical installation will have a number of zones depending upon the system design, which will ensure the ultimate in comfort and efficiency. The complete manifold system and control system occupy a very small area.

How many thermostats can I have?
You can have as many thermostats as you have rooms. If you would like to, in some rooms you could even have two!

Do I need a separate set back control?
No! Setback control is an option that is easily added to Stat Link. This feature allows you to automatically set back rooms not in use.

How do I control air conditioning?
You will need a separate thermostat to control the air conditioning system.

How much does it cost?
Stat Link controls are a standard feature when using Heat Link. The cost would be included in the total per square foot job cost.

How reliable are the controls?
Stat Link controls are solid state reliable and carry a factory one year warranty. As an upgrade, Heat Link offers up to ten year extended parts and labor protection.

Can I have different temperature settings for each room?
Yes, every where you have a thermostat you can have a different temperature setting.

What if something breaks?
Stat Link controls are factory tested and are very easy to install and trouble shoot. Repair parts are available from any authorized Heat Link contractor's and distributor's within 24 hours.
