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.

Reznor Ultra High Efficiency Condensing Gas Fires Unit Heaters - 93%

Reznor® V3 Series Model UEAS gas-fired, high efficiency, separated combustion unit heaters are available in 4 sizes ranging from 131,000 to 305,000 BTUH gas input. Heaters are designed for up to 93% thermal efficiency and are approved for installation in the United States and Canada by ETL.

Reznor® V3 Series unit heaters have a refreshing appearance with a glossy white cabinet finish and less visible hardware. Each size cabinet is easily suspended from 4 suspension points. The low voltage terminal strip on the outside of the cabinet makes connecting control wiring easy with no panels to remove. The addition of a “G” terminal to the low voltage strip, along with the new design of the circuit board, allows for fan only operation (without adding relays). All units have a factory installed gas line nipple to the exterior of the cabinet for easy gas service connection. The secondary heat exchanger has a 1/2” PVC pipe for attaching a coupling for ease of installation and cleaning of the required condensate drain. A 4” PVC cleanout cap that is drilled and tapped for a 1/2” NPT fitting is furnished with the heater for attaching the vent condensate drain.

The preeminent new internal feature is the Tcore3® heat exchanger and single burner combustion system. Other standard features include a single-stage gas valve, multi-try direct spark ignition with 100% lockout, pressure switch to verify vent flow, venter motor, aluminum venter wheel with housing, resiliently isolated axial fan and motor assembly, a high temperature limit control, interlock door switch, and a built-in disconnect switch. Operation is controlled through an integrated circuit board. The circuit board monitors heater operation and has LED diagnostic indicator lights to identify abnormalities in control functions.

We introducing New Product for North American Market- Eternal Hybrid Water Heater.

What is Hybrid Water Heater and why it is better solution for your house than Tankless Water Heater or Tank Type Water Heater?

Eternal hybrid is a more effective water heating system. The advanced multi-pass heat exchanger drives heat downward then recycles it through 44 baffled stainless steel pipes for maximum efficiency. Water spreads thinly and evenly around the 44 heating pipes to absorb heat quickly. Cold water flows from the bottom up to prevent sedimentation build-up associated with other designs and the straight water-flow design eliminates pressure loss associated with coiled pipes. And because water flows around the pipes — not through them — there is no risk of build-up inside the pipes.

• Patented counter-flow technology maintains 86% efficiency and delivers hot water faster than tankless units for multiple applications at once .
• Half the size of a 50 gallon tank water heater with 300% higher output .
• Built-in reservoir eliminates cold water sandwich and allows you to build a recirculation system with no external electric tank .
• Extremely low exhaust temperature allows Eternal to be PVC vented for easier, more economical installs .
• Multistage safety features .
• Near zero greenhouse gas emissions means Eternal is one of the cleanest burning appliances on the market .
• Stainless steel reservoir is self cleaning and maintenance free, and backed with a 20 year no-leak warranty on stainless steel heat exchanger tank for residential, 10 year warranty for commercial, limited 3 year warranty on all other parts, and 1 year warranty on reasonable labor

HydroNex Per-Piped Mixing Radiant Panels Benefits

HydroNex panels are the perfect solution for any radiantproject: floor warming, heating, or snowmelting. Pre-piped, pre-wired, and factory tested with a professionallooking enclosure, these panels will dramatically reduceinstallation times as well as virtually eliminate wiring andother start-up problems.

Each panel comes pre-wired with a 120 volt power cord. Simply plug the HydroNex panel(s) into a standard wall outlet.

Electrical connections are even easier with the CAT5 connection system. Control logic passes between panelsthough a CAT5 cable, enabling each panel to “talk” to each other. The only wiring required is to connectthe zone thermostats to the correspondingrelay terminal.

Connecting one panel to another is as easyas turning the hex nut on the brass o-ringseal union. Each union can withhold up to 100psi when only hand tightened.

Why HydroNex?

• Fast installation – Cut installation time and make more money!
• Simplify bids with fixed costs
• Easy maintenance
• Factory assembled and tested – HydroNex panels are guaranteed to perform
• Professional presentation
• Performance engineered
• Plug-n-play CAT5 electrical connectors – Reduce wiring and start up problems
