Underfloor Heating PDF Print

Hard floor surfaces can feel cold in the winter months even when the air is heated to normal temperatures. Because the floor surface has more mass than the air, the floor never reaches the temperature set by the air sensing thermostat.

What is the solution?

Underfloor heating systems make floor surfaces feel comfortably warm, plus all surfaces within the room are heated to the same temperature as the floor. This includes the walls, furniture, and of course, you.

In order to heat the floor, the underfloor heating system uses warm water running through plastic tubing that is installed in the floor. Warm water from the boiler is circulated through the floor using pumps and valves. The boiler can be heated using natural gas, propane, heating oil, electricity, or wood, and there are also options for solar hot water panels to heat your home.

There are several comfort and health benefits to radiant floor heating. It is very easy to provide indoor temperature control for each room or zone within a home. This allows you to keep your regular living areas warm and comfortable while reducing the temperature in guest rooms that are used infrequently. Individual control of areas (zones) can provide the greatest comfort for each room while providing the option to control your energy costs.

When installing an underfloor heating system, it is important to choose the right equipment.

Regular thermostats are not well suited to operating underfloor heating systems. These thermostats turn on the radiant floor when the air is below the temperature setting, and shut off when it's above the temperature setting. The result is the floor tends to shoot past the air heating temperature when heating and then does not turn back on until the floor temperature is cold. It can be quite unpleasant riding this temperature rollercoaster!

Choose a thermostat or room controller designed specifically for underfloor heating.

kanmor has over 25 years of experience controlling underfloor heating systems from thermostats and room controllers all the way to boiler controls. Our thermostats and room controllers use Pulse Width Modulation and Indoor Feedback technology to periodically pulse the floor with the right water temperature so that the floor maintains a steady constant temperature, thereby maintaining the best in temperature comfort.

They also include the option to install a floor temperature sensor. The sensor is used to provide the following options:

  • Hardwood floor temperature limiting. Hardwood floors can dry out and suffer damage due to thermal expansion. kanmor thermostats allow a maximum floor temperature to be set. Many hardwood flooring companies specify a maximum temperature of 30ºC.
  • Maintaining a minimum floor temperature. This is especially useful in bathrooms. By maintaining the floor between 25 to 30ºC, the floor feels warm to the touch.
  • Maintain comfort in rooms with large amounts of southern facing glass windows. These rooms are often overheated during the day by solar gain through the windows. Typically this could result in the radiant floor going cold during the day. By maintaining the floor near the desired room air temperature, the room remains comfortable, even when the sun sets in the evening.

In order to provide energy savings, kanmor thermostats and room controllers also include the option to provide a programmable night setback schedule. This reduces the temperature during the night, thereby providing energy savings. Room controllers also include Optimum Start and Indoor Temperature Feedback together to ensure that the room and floor is up to the desired temperature, ready for you to start your morning.

kanmor also has solutions for boiler control, operation of cooling systems, and remote internet access options for your radiant floor heating system. So enjoy the ultimate in comfort with a radiant floor heating system controlled by kanmor.
