How Much Insulation Is Best for My Attic?

An uninsulated attic is the principal cause of energy loss in a home and also the place where the loss is the most sizeable. However, attics are also the easiest to insulate, so here are a few pieces of advice about how to get the thickness of the insulation right.

The first thing to do before you make any decision related to insulation thickness is to assess whether your current insulation is right. Look at the insulation on the attic floor – if the floor joists are visible under the insulation, you need to add more. The next step is to decide what type of insulation you should add and how much. You can use various different materials, fiberglass sheets are the most common, but you don’t need to add the same type as the material you already have, you can simply combine various materials to reach the desired thickness. The most relevant parameter to check is the material’s R-value that measures its ability to seal off the air flow in the area of application. The recommended value is R-38, which means that the insulation that you lay should be between 10-14 inches thick depending on the type of the material.

Make sure you stay warm and cozy this winter, and allow Enviro-Gas to take care of all your propane Brighton delivery and maintenance needs!

Does A Programmable Thermostat Reduce Home Heating Costs?

Image
Installing a programmable thermostat is indeed an excellent way to reduce home heating costs – here is how these small and very efficient devices work and how you can use them to reduce your energy bills. Programmable thermostats allow you to set the times when your heating or cooling system turns on and off. They are able to store multiple schedules and to repeat the pre-programmed settings indefinitely or as long as the parameters entered remain unchanged. The best way of reducing your energy bills with the help of your programmable thermostat is by setting the thermostat to maintain a lower temperature during the day when you are away from home. If you know that you will be away for 8 hours, program the device to turn on the heating an hour before you arrive home, that way you can return to a warm home without having to pay for the heat produced while you are not at home to enjoy it. You can also program the thermostat to turn off automatically or to keep the temperature at a lowe...

What are the Most Common Types of Residential Heating Systems

Image
The choice of a heating system depends on the type and purpose of the building, the interior requirements for thermal comfort, the way of using the heating system, the correlation with a ventilation/ air-conditioning system and, not least, on the beneficiary's financial availability. Popular system types: Forced air furnaces They use propane, new gas or oil as fuel and provide a good efficiency (80-90%).These systems use ductwork and vents for heat distribution throughout the house, and the temperature is controlled with a thermostat. The benefits of installing an air furnace include thermal comfort, proper ventilation, improved air quality and an overall healthy environment. Electric heat pumps This option constitutes an energy-efficient solution to furnaces and works great for moderate heating needs. A heat pump is similar with an air conditioner when it comes to the refrigerant cycle and is made from a compressor, a condenser, an evaporator, an air handler and a reversin...

How to Make Your Home Energy Efficient

Image
A comfortable home does not only feature comfortable interior design elements, furniture pieces, decorations or a larger space. It is also about the thermal comfort. What is energy efficiency? We hear very often about of energy efficient housing. Energy efficiency represents all the ways we can get the desired comfort and consume less energy. A house is considered energy efficient when it is independent of the weather conditions. The importance of efficient energy consumption caught the attention of corporations and individuals alike, due to its many benefits: lower energy consumption, environmental responsibility, ensuring a better future, compliance with energy efficiency principles and ultimately lower costs. How can you have an energy efficient home? This can be achieved right from the construction stage of a building, or through the rehabilitation of an existing building. Here are a few solutions: Interior thermal insulation (walls and floors) that prevents the heat from m...
