According to Green Choices, heating a home with mains gas paired with an energy-efficient condensing boiler is likely to be the least expensive option, providing mains gas is available in an area. This is also one of the least polluting conventional ways to heat a home. Other popular methods used to reduce heating bills include replacing a gas boiler with a more energy-efficient model and using a programmable thermostat.Know More
If a boiler is more than 15 years old, NBC's Today: Home and Garden recommends replacing it with a high-efficiency model. These newer units use far less gas than older ones, boasting efficiency ratings of at least 94 percent. In addition to replacing a unit, NBC's Today: Home and Garden recommends adding weather stripping around doors and windows as a way to make heating less expensive. This action, they explain, cuts down on draftiness and can increase the energy efficiency of any one opening by up to 70 percent. Also consider installing a programmable thermostat. Costing between $40 and $100; they automatically lower the temperature when residents are out of the home, as not to waste fuel to heat an empty home. Installing a programmable thermostat does not require any special skills, and directions generally come in the package.
If Mains gas are not available in an area, Green Choices recommends an oil-fired boiler. These have increased in efficiency in recent years, though fluctuations in oil prices make them a less optimal choice than gas boilers.Learn more about Heating & Cooling
A heat pump is a mechanical compression cycle refrigeration system that is used to either heat or cool an area. Heat pumps work by transferring heat from one body, such as the ground, air or water, to another body. This can also be reversed to cool an area.Full Answer >
It is not necessary to insulate the area between the rafters in an attic. Leaving the space between the rafters open promotes airflow and reduces moisture.Full Answer >
Air conditioners work by removing warm air in an enclosed area and leaving only cooled air to circulate. The cooling effect is achieved by filtering the indoor air through evaporator coils with a cold refrigerant and streaming the cooled air back into the room. This process also effectively dehumidifies the indoor air as the moisture condenses and collects on the coils and then drains away.Full Answer >
To cool a room with an area of 700 to 1,000 square feet, one needs 18,000 BTUs per hour. The number of BTUs needed to cool a room depends upon several factors, the most important being the area. The larger the area, the more BTUs are required.Full Answer >
