A system can be designed to provide 100% of heating needs on the coldest days in northern Canada, but the cost to install such a system would be excessively high. A system designed to provide 70% of a calculated heat load is the optimal sizing if there is a supplemental heating element, but there were past errors in calculating the heat loss and, consequently, some systems were under-sized. The new CSA standard for installation (C448) has been revised to overcome this deficiency.

A heat loss calculation will determine how much heat is required for both applications, but most systems are sized to meet less than the full design load and rely on an electric backup heater to provide supplemental heat on very cold mornings during the winter. In all cases, full cooling load can be met by a system.

The solar heat that is transferred out of the ground can be used either to warm air (for use in a forced air distribution system) or to heat water (for drinking or service applications, or in radiant heating or swimming pools).

Each unit has one only compressor, and can only heat or cool at any given moment. ICI systems require more than one unit, and the greater the number of units (ie: the larger the system), the more balanced the load. For example, schools can use one unit to extract heat from a gymnasium to provide cooling, and transfer the heat to the unit serving the library, where heat is required.

Yes. One of the many advantages of the Maxim is the ability to heat multiple buildings from one location.

Virtually all heat pumps are available with supplemental electrical heat. Some heat pumps are used in conjunction with a, fossil fuel heating system such as gas or oil. Whether supplemental heating is necessary depends on your climate and home location. Your local contractors can advise you as to whether supplemental heat is necessary, and what type of heat pump might be best for your needs. A heat pump can be a worthwhile consideration no matter what heating system is used in a home.

Some units integrate a HRV unit that can provide fresh air and enhance building comfort, and offer enhanced defrosting without creating negative pressure inside the building.

Your contractor should provide a heating and cooling load calculation (heat loss, heat gain) to guide your equipment selection. Geothermal heat pumps are sized to meet your cooling requirements. Depending on your heating needs, a geothermal heat pump will supply 8O to 100 percent of your design-heating load. Sizing the heat pump to handle your entire heating needs may result in slightly lower heating costs, but the savings may not offset the added cost of the larger heat-pump unit.

Twenty percent of the average energy demand in a residential home is for water heating, and most units include a component to heat water for potable or sanitary use. Heat pumps can also be used to dehumidify indoor swimming pool areas, by controlling condensation with a minimum of ventilation and using the recovered heat in the main heating process.

Yes. Supplemental electric heat is available on most EMI systems (factory installed only). Check the specific evaporator specifications for all available options. a reference guide please refer to the SIC condensing unit specification sheet to compare the capacities of the other manufacturer’s unit to an EMI unit (bulletin 01010). EMI will not warrant use of EMI heat pumps with other than approved EMI evaporators.

Your contractor should provide a heating and cooling load calculation (heat loss, heat gain) to guide your equipment selection. Geothermal heat pumps are sized to meet your cooling requirements. Depending on your heating needs, a geothermal heat pump will supply 80-100 percent of your design heating load. Sizing the heat pump to handle your entire heating needs may result in slightly lower heating costs, but the savings may not offset the added cost of the larger heat pump unit.

a fluid is circulated through the buried pipe, it attracts heat from the surrounding ground; the further the fluid flows, the more heat it can extract. When the warm fluid returns to the compressor, heat is taken from the fluid and transferred to the heat pump, where it warms air prior to circulation throughout the building.

All Homesteader and Coalman furnaces heat a water/glycol mixture. The heated liquid is pumped through insulated underground plastic pipes to all the different locations that need heat. The Heat is then transferred out of the liquid and the cooled liquid is pumped back to the Homesteader or Coalman for reheating.

Cold is the absence of heat. In summer, heat from the building is transferred into the fluid used in the loop (by means of a compressor) and, as this fluid circulates, the heat is rejected (discharged) into the ground around the loop pipe. By transferring heat out of the building, this provides cooling and dehumidification.

The loop is buried below the frost line, and insulation is used to protect any section that may rise above the frost line (eg: as the pipe enters the building) to avoid freezing in winter.

When the loop cannot obtain sufficient heat from the ground, most systems include a back-up electric element to provide supplemental heat. If the demand for heat is higher than the combined supply from the outside loop and the electric backup, most systems will shut down. Note: the backup electric system continues to provide heat until the problem is fixed.

air-source system is a similar concept to an EE system, but it extracts heat from outside air instead of from the ground. Winter air does not contain much latent heat, and the efficiency of an air-source unit drops significantly when outside temperatures drop below 0oC. The compressor in an air-source unit is located in the outdoor compartment, where it is noisy and exposed to weather elements.

The heat pump can produce water that is hot enough for use in these applications. In most cases, it is not warm enough to be used in old-style under-the-window radiator systems.

The CSA standard specifically bans locating a ground loop near septic systems to avoid retarding the microbial action to decompose sewage. Grey water from the building can be used in some situations, if that collection unit is separate from the septic system.

Better known as Evangelism Explosion International, EE is a grassroots training organization whose sole purpose is to glorify God by equipping believers to multiply in and through local churches worldwide. EE is attempting to reach every person in the world with the Gospel of Jesus Christ by equipping every people group and every age group to witness to every person. EE is a worldwide ministry in every nation of the world.

Supplemental is an assessment of improvements that have been on the property for more than a year but not included in the last assessment. The supplemental assessment is the difference of what was assessed and what should have been assessed.

The building is primarily an ice rink and the temperature must be kept below freezing on the floor. If you are sensitive to this issue be sure to bring some warm clothes. When the ice is removed during the summer (May to August) coldness should not be an issue. Notify the Rockets and they will try their best to see what they can do, phone 860-7825, fax 860-7880.

Without ducts, the only option is to circulate heated water through a radiant in-floor configuration, or small fan coil units.

The most common error symbol that appears on the display panel is a EE with a down arrow and two numerals. The reason for the EE Error Indicator is generally caused because the cuff has been wrapped too loose. The cuff was under-inflated during the measurement. This error will also display if the cuff is worn and needs to be replaced. The EE symbol with a down arrow indicates the cuff is over-inflated.

First, check with your payroll or benefits office to be sure your employer offers both series and that your payroll system allows more than one bond. Ask how you should submit the request. For many employers, you can simply submit a new enrollment form as in question 2.1 above. NOTE: Some employers accumulate allotments for all of an employee's bonds at the same time. Other employers issue the bonds in rotation.

Look at the first letter of the call number to find the stack level on which the book is shelved, or go to the proper department. A printed guide to the bookstacks is also available. You will need a picture ID to enter stacks. If a book is not on the shelf or you can't find it, a librarian can accompany you to the stacks to help you locate it. Be creative when you try to think how it might be misshelved.

The earth has the ability to absorb and store heat energy. To use that stored energy, heat is extracted from the earth through a liquid medium (groundwater or an anti-freeze solution) and is pumped to the heat pump or heat exchanger. There, the heat is used to heat the air. In summer, the process is reversed and indoor heat is extracted from indoors and transferred to the earth through the liquid.

The BATIMAT in Paris (the world's biggest construction fair) has shown impressively the various and progressive ways in which heat-insulation films with integrated multiple reflection are used worldwide in the building industry as a means of solving problems by taking advantage of their ecological and economic assets.

A minimum of sixty-five degrees must be maintained at all times. A temperature of less than sixty-five degrees fahrenheit shall be deemed injurious to the health of the occupants.
