   The floor of the furnace is mostly made of a different material from that of the wall, typically hard castable refractory to allow technicians to walk on its floor during maintenance. A furnace can be lit by a small pilot flame or in some older models, by hand. Most pilot flames nowadays are lit by an ignition transformer (much like a car's ...

3. Construction estimating software - Wikipedia

   As a result, commercial cost estimating software applications were originally created to overcome these errors by using hard-coded formulas and data structures. Other benefits include the use of reference to cost databases (aka "cost books") and other data, predictable and professional looking reports, speed, accuracy, and overall process ...

4. Furnace (central heating) - Wikipedia

   en.wikipedia.org/wiki/Furnace_(central_heating)

   In some areas electrical resistance heating is used, especially where the cost of electricity is low or the primary purpose is for air conditioning. Modern high-efficiency furnaces can be up to 98% efficient and operate without a chimney, with a typical gas furnace being about 80% efficient. [1]

5. Ground source heat pump - Wikipedia

   The financial viability of these systems depends on the adequate sizing of ground heat exchangers (GHEs), which generally contribute the most to the overall capital costs of GSHP systems. [52] Commercial systems maintenance costs in the US have historically been between $0.11 to $0.22 per m 2 per year in 1996 dollars, much less than the average ...

6. Life-cycle cost analysis - Wikipedia

   en.wikipedia.org/wiki/Life-cycle_cost_analysis

   The term differs slightly from Total cost of ownership analysis (TCOA). LCCA determines the most cost-effective option to purchase, run, sustain or dispose of an object or process, and TCOA is used by managers or buyers to analyze and determine the direct and indirect cost of an item. [1] The term is used in the study of Industrial ecology (IE ...

7. Low-Income Home Energy Assistance Program - Wikipedia

   The 2008 spike in funding was needed to address the sharp increase in home heating oil. The recent decrease in allocations prior to 2008 levels may not be enough to handle the continued climbing of heating costs and its effect on many households with low incomes. Not only are fuel prices continuing to increase, program recipients are on the rise.
