Tekmar 256 Outdoor Reset Boiler Control

Tekmar Save Money on Home Heating Bills

Energy Saving Features

Outdoor Reset:


As the disparity between indoor & outdoor temperature increases, so does the rate of heat transfer from hot areas to cold.

A building's heat loss or gain depends considerably on two things:

Outdoor air temperature (as temperature difference between the exterior and interior increases, so does the rate of heat transfer) The building envelope's resistance to heat transfer (a higher R value in building materials will impede the transfer of heat) While a control will not impact the R-Value of building materials, it can ensure that the system does not waste heat by exceeding current requirements. Providing only the required amount of heat reduces fuel consumption, creating less pollution while saving you money.

How an Average Heating System Works...

When the interior air temperature drops below the thermostat setting, a signal is sent to the boiler to turn on. Unfortunately, the thermostat only tells the boiler to turn on when the house is too cold or turn off when the house is too warm. There is no in-between.


How many miles per gallon would your car get if the only method of controlling your speed was to accelerate until you're going too fast, and then apply the brakes?
How Your Heating System Should Work...

You adjust your car's gas pedal to maintain a comfortable driving speed and good fuel economy. Why not the same with your heating system? By adding a tekmar Outdoor Reset Control, heating system water temperatures are adjusted to maintain comfort and improve system efficiency.



It's Not Your Heating System's Fault!


If a heating system does not know if it is a cool autumn night or the coldest winter day, it works as if it's always the coldest day of the year and heats the water to a maximum temperature. Having this hot water in the distribution piping when it's not needed results in stand-by heat loss. By adding a tekmar Outdoor Reset Control that works alongside of your boiler and thermostat, you may see energy savings of up to 30%.

Scheduling & Setback:

Many tekmar thermostats include easy to use scheduling features. Scheduling allows for a reduction in temperature (setback) for rooms that are not expected to be in use. More detailed information about scheduling and setback can be found here.



Purging

This feature allows for continued circulation of any heat left in the high temperature areas of the system. Residual heat is used by the living space instead of being lost to the mechanical room. Some controls will also supply heat using circulating water prior to operating the boiler if it appears that there is enough heat left in the system to satisfy current requirements. This means that the boiler is turning on and off less frequently, saving fuel.
