Topic Founder & Author: Dennis C. McCreery. First of all, outer burial containers and burial vaults are not required by state or federal law. They are required by most cemetery rules and regulations. Cemeteries want a casket placed in an outer burial container or burial vault to prevent the ground from sinking in above the casket.
A heat pump will replace both the furnace and air conditioner/central air unit. It may be costly to install, with the national average falling between $3,956 and $6,702, but it will save you considerable money in energy costs.
Using these prices, a heat pump with a COP of 3.5 in moderate climate would cost $0.97 to provide one therm of heat, while a high efficiency gas furnace with 95% efficiency would cost $1.22 to provide one therm of heat. With these average prices, the heat pump costs 20% less to provide the same amount of heat.igher COPs equate to lower operating costs. The COP may exceed 1, because, instead of just converting electricity to heat (which, if 100% efficient, would be a COP of 1), it pumps additional heat from a heat source to where the heat is required.
