Correct Sizing of heating and cooling system will provide more comfort at lower cost
Correct sizing of heating and cooling systems is necessary to get better performance from the air conditioning and furnace. A better output means efficient use of the energy, less wear and tear to the system ad more comfort to the occupants. Ultimately the aim is to heat, clean, ventilate, humidify and dehumidify the internal environment of the home properly so that it enhances comfort and health of the occupants.
In older homes the heating and cooling systems are often neglected until the system completely dies. An early retirement of the air conditioning and furnace can be quite cost effective over the long run. When installing a new system the heating and cooling system should be properly sized to achieve a higher efficiency. The heating cooling system should neither be undersized or over sized, because in both cases it will mean a less comfortable system, potential health hazard, increase in running cost, higher energy cost and more stress on the system. If installing a radiant heating system the issue is the same. The boiler and the radiator should be sized to match each other. The radiators should be placed in rooms in such a manner that they provide uniform heating and do not result in hot and cold areas in the house.
For sizing heating and cooling systems the home air conditioning requirements are calculated by taking into account several variables like room volumes, insulation of house, windows, air ducts, house leakage, and orientation of house, heat gain from lightning, appliances and occupants. This data is fed into a computer program that is based on calculation from Manual J for residential application by Air conditioning Contractors of America. The software program provides accurate heating and cooling load requirements by taking in to account all the crucial data of the house. This helps the residents of the house to get a tailor made solution to their air conditioning problems.
In the end by adopting the right sizing method the homeowner can easily save a significant amount of energy throughout the year. This means a reduced utility bill and saving more money in the long term. You can know more at www.absoluteheatingcooling.com.

How do you work out the size of heat mat you need?
I'm keeping Land hermit crabs and they are currently in an 18 inch glass tank. I'm planning on upgrading them to a 3ft tank soon.
Most heat mats have information on the package to help direct you. It is usually based on "gallon" size of the terrarium. Other factors that should be considered are what type of substrate you have and how thick it is. Some, like sand or gravel conduct the heat, others, like coconut fiber insulate against the heat.
Either way, you'll put the pad at one end and let the crabs choose where they are most comfortable.
Usually, the rule of thumb is to get a pad that covers at least one third, but no more than one half the base of the "tank".
an overhead ceramic heat bulb is another option.
