Choosing an Energy Efficient Model

Home Heating SystemHeating your home usually accounts for a large percentage of your overall utility bill. When purchasing a new system energy efficiency is critical. Central heating systems which have a central unit which distributes warm air, water, or steam throughout the home are installed in most homes these days. You will want to compare energy usage, maintenance costs, and installation costs when considering which type of system is right for you.

Furnaces

Furnaces use heated air to warm up the house. Large supply ducts deliver warm air throughout the home while smaller return ducts bring cooler air back to the furnace. A blower is used with a forced air system to distribute warm air throughout the home. Registers in the various rooms are the entry point for the heated air. Air that returns to the furnace is pushed through a filter to remove dirt and dust before it is sent back into the home.

Using Solar Power to Heat Your Home

The heating needs and design of the home must be carefully considered when choosing a solar energy heating system. The first choice you will have when using solar is whether to install a passive or active system. Active systems use panels to collect heat from the sun and then distribute it with an electric fan. Since these systems will store heat to use when there is no sun, they are often much more practical. Passive solar systems are very simple, which probably accounts for their popularity. They will not work in your home if your lot is shady. Always consult a professional prior to installing a solar heating system.

Liquid and air are the type main types of active solar heating systems. Liquid systems transfer the heat that is produced to hydronic collectors with the aid of either water or an anti-freeze solution. In air systems air is collected, heated, and stored for later release. Both systems use collectors to capture solar heat and then store it for when it is needed.

Boilers

Hot water is heated in the boiler and then sent throughout the home to radiators. Hot water is lighter than cold water, so it rises and goes out to heat the home while cold water will return to the boiler. Water is sent to the radiators through pipes with the aid of a pump. To keep pressure from building up in the system the expansion tank of the boiler acts as a cushion.
