Older furnaces may deliver only 50%-60% efficiency. If your heating and cooling system is over 10 years old, you might be surprised to find out just how many advantages there are to the new systems. A properly installed furnace can provide 90+ AFUE heating efficiency. In fact, many of our furnaces exceed the EPA Energy Star rating. And with energy savings of up to 40%, the investment can be financially worthwhile. The savings on monthly utility bills will pay back the cost several times over the life of the equipment.
Other advances like computerized programmable thermostats, variable speed air handlers and the new scroll compressors on select models make newer systems quieter, more efficient and more comfortable than ever.

What you can do to help your heating or cooling products run smooth during the seasons you need them most:
Follow the manufacturer's maintenance instructions which generally include these instructions:
- Keep air-supply outlets and return inlets clear of obstructions.
- Clear leaves, brush, and dirt as they accumulate on the outside unit. If there's a pipe for draining condensate water, check it for blockage.
- Check the air filter once a month during the operating season. Replace it if it looks dirty (some are washable).
Invest in a digital thermostat to program temperatures for your system to follow throughout the day. For example, if no one is home during the day, a programmable thermostat can run the air conditioner or furnace at a temperature that will require less energy, then the program can adjust itself to a temperature to your liking one hour before you come home.
Routinely have a professional contractor perform a pre-season check-up. Having your furnace inspected and serviced regularly is the best way to make sure you get the most from your investment. Depending on your area's climate, things like clogged filters, sooty flues and un-lubricated fan motors can reduce your system's efficiency by up to 25%. Plus a trained technician can spot trouble--before you're left out in the cold. A check-up can save you time, money and keep you comfortable during the coldest days. Here are some of the services your technician will perform during a system check:
- Inspect your heat exchanger, unit wiring, flue pipes and all components.
- Check air filter, safety controls, fan switch, fuel line and shut-off valves.
- Clean burners, ignition components and blower wheels.
- Lubricate motors to ensure smooth and efficient operation.
- Secure all panels.
- Calibrate thermostat for accurate and efficient performance.
- Record system performance.

High Efficiency Boilers
18.28
sn
High efficiency boilers are furnaces that operate by taking advantage of condensing to lower energy consumption and energy bills. This type of boiler is favored by many for its financial and environmental benefits.
How High Efficiency Boilers Work
High efficiency boilers save energy by recovering heat that would normally by removed through the flue system of an older model, non-condensing boiler. High efficiency gas boilers have large heat exchange mechanisms that enable them to maximize the transfer of heat from the burner. In the condensing mode, high efficiency boilers simply limit the loss of flue gases. This enables high efficiency boilers to take better advantage of heat produced.
Efficiency Ratings
Boiler models have efficiency ratings that rank from A to G. High efficiency boilers, which are always condensation models, have an A rating. A boiler's efficiency is a concern for those who want to keep energy bills as low as possible.
Boilers Efficiency has Several Impacts
High efficiency boilers are considered the superior models for a few advantageous reasons over non-condensing models. High efficiency gas boilers not only save money, but they reduce the use of natural gasses, as well. This makes high efficiency boilers the more environmentally friendly choice.

Evaporative Cooling - revealing the "Con" in air conditioning
19.00
sn
The energy-savings of this sort of cooling are staggering (90% plus!) when compared with air-conditioning. If you think that air-con accounts for 15% of total US energy-use (261 billion kW annually - this incidentally also equates to the entire annual fossil fuel consumption of Africa), the possible money, energy and ecological savings offered by this sort of technology are remarkable.
Now, evaporative cooling does not reduce temperatures to as low a level as air-con. It will typically bring temperatures down to about 21°C, but this is a very respectable, comfortable level for a hot summers day. There are other significant advantages which we show in the table below.
| Evaporative Air Cooling | Refrigerated Air Conditioning |
| Uses 10% of the electricity required by conventional air conditioning | High electrical use due to refrigerant circuit compressor |
| No refrigerants | Uses environmentally damaging refrigerants |
| Supplies 100% fresh, outside air and cools it | Produces recycled internal air that is cool |
| Low Carbon Dioxide footprint | High Carbon Dioxide footprint |
| Simple engineering, easier and cheaper to maintain | Complex engineering, hard and expensive to maintain |
| Low purchase cost | High purchase cost |
| Performance improves at high temperatures | Performance reduces at high temperatures |
| Open windows and doors provide effective evacuation of air | Must not leave Windows & Doors open |
As a sufferer of air-borne allergies at work caused by air-con, I love that one about being able to leave windows and doors open!
This sort of cooling does raise relative humidity within the space being cooled, however at temperatures below 25°C (which is what you're getting) this does not produce any feeling of discomfort. Nor is there a risk of condensation occurring if you follow the design guidelines for ensuring balanced airflow and evacuation that need to be followed when installing this sort of unit.
The question of Legionella does not apply to these systems as they operate below 25°C, do not let water stand and do not emit water droplets. In 3 million installations worldwide, there has not been a known case of Legionnaires.
Evaporative Cooling really does present a compelling energy-saving case against air-con and while it won't compete in instances where really low working temperatures are required, for 90% of home or commercial applications, it sits right in the comfort zone.

The PEX tubing advantage for radiant floor and underfloor heating
03.44
sn
PEX tubing is being extensively used these days in all kinds of heating needs both in residential as well as commercial areas. And the reasons for these are many. Here are few factors that give PEX tubing an edge over the others in underfloor heating.
- Excellent carrier of water: One of the many advantages of PEX tubing is that it is an excellent carrier of water and hence is a reliable and durable solution for heating pipe needs in all industrial areas.
- Economical solutions: PEX tubes are cheaper than other materials used in radiant floor heating. For example the prices of metals are all time high and are growing each passing day. PEX tubing on the other hand is cost effective as well installation time is comparatively less.
- User friendly installation: For installation purposes, PEX tubing is the best as they are flexible and can be bent even round the corners. This is unlike the case with metal which are rigid and are a practical problem to install through floor joist.
- Easy joining method: Unlike other metal tubes, PEX tubes can be joined with cheap tools and using the cinch ring method without the use of solder, heat, pastes and glues.
- Durability: PEX tubing is better than metal tubing for radiant floor heating as they are resistant to pitting, corrosion, water hammer and scale build-up.
- Leak resistant: PEX tubes are extremely durable and reliable. They perform great even in adverse conditions like when the temperature is below zero degrees. This is especially great in cold countries where PEX Tubing is extensively used for Underfloor Heating etc. purposes.
- Versatility: PEX tubes are versatile and can be used in water distribution systems; ice melt systems and sprinkler systems other than in radiant floor heating.
- Energy efficient solution: These tubings are energy efficient solutions as they can retain more Btu per foot than other metal pipes.
More and more industrial sectors are using PEX tubes these days for all kinds of heating needs. For whatever purpose you use it; just make sure to order the ones that follow the ASTM standards for safety reasons.
