Toilet Tank Condensation Problems and Fixes

Toilet tank condensation may not seem like a big deal at first, but it can quickly lead to bigger problems. Water can seep into the floor and eventually cause the floor framing and sub-floor to rot. Additional problems include soggy drywall and mold and mildew growth on the walls and baseboard.

Condensation occurs whenever damp, warm air meets a cold surface. Lowering the temperature of the tank is one way to avoid this problem. A faulty flapper causes cool water to trickle constantly through the toilet, which makes the tank colder. You can replace the flapper and valve for less than $25 if you do the work yourself.

If your flapper is working the way it should, you can try insulating the toilet tank. A local home improvement center should have kits available for approximately $20. The problem with this solution is the time and hassle involved in installing the insulation. You will have to cut the foam panels to the right size, empty the water out of the tank and glue the panels to the inside walls of the tank.

Taking shorter showers with cooler water is one way to lower the humidity in the bathroom during the summer when the weather is hot and humid. After your shower, leave the bathroom door open and turn the fan on to exhaust the humid air. Waiting to flush the toilet until the room has dried out is another way to keep the tank from filling with cold water when the conditions are ideal for condensation to occur.

If your toilet is old, you can consider installing a low-flow toilet. This type of toilet requires less water per flush, so you will simultaneously reduce your water usage. By investing a little more, you can purchase a toilet with an insulated tank. If you want to avoid having to replace the entire toilet, you can swap out the old tank for a new one that comes with insulation installed at the factory.

You can save thousands of dollars in unnecessary repairs by using any of these tips to eliminate toilet tank condensation.

Do HVAC Systems Emit Greenhouse Gases?

Most scientists and environmental experts believe that greenhouse gases are responsible for depletion of the ozone layers. It’s a well-known fact that all heating and air conditioning systems release the harmful substances into the atmosphere. This applies for all equipment types, from central cooling unites to portable air conditioning units and window-mounted air conditioners.

What is the Ozone Layer?

Located in the upper atmosphere, the ozone layer is responsible for safeguarding the earth from harmful ultra-violet radiation from the sun. As this layer continues to deplete, more radiation seeps through. This consequently leads to a rise in the earth’s atmospheric temperature. The effect is referred to as global warming.

To reduce the detrimental effect of greenhouse gases on the ozone layers, authorities have initiated policies that mandate production of better equipment. Manufacturers are instructed to ensure that their devices are more energy efficient. Newer devices are also required to have a minimal environmental impact.

Do HVAC Systems Emit Greenhouse Gases?

An AC system is comprised of an electrical pump and a network of coils that transfer air between the exterior of a building and the indoors. Warm air is moved outside by the condenser while cool air is released indoors using an evaporator. A refrigerant constantly moves through the system while transforming its state from gas to liquid and vice versa. This refrigerant is what facilitates air movement, and is one source of the harmful greenhouse gases.

Previously, air conditioners used a liquid refrigerant whose components included chlorofluorocarbons, known as CFCs in short. These were found to contribute towards the depletion of the ozone layer. With time, AC manufacturers began to use halogenated chlorofluorocarbons (HCFCs). These have a lesser impact on the ozone layer, though they still cause harm. As a result, HCFC production is scheduled to be phased out by the year 2030.

To contribute towards environmental conservation, all consumers are encouraged to purchase better systems that are certified to be energy efficient. The government runs various programs which set energy efficiency standards and certify all new HVAC models. Such ACs use about 10% less energy, which helps save the environment and also saves homeowners money on energy bills. Other steps to improve efficiency include improving insulation and sealing ductwork to reduce heat losses.

Types of Commercial Heating Systems

465316451If you own a commercial building, one of the biggest expenses you have to consider is the cost of installing and operating a heating system. Selecting the right product for your needs requires you to research the various types of commercial heating systems available.

Experts in the industry advise consumers to factor in the cost of maintenance when deciding which type of system to purchase. These costs vary widely depending on which system you choose. You can reduce operating costs by selecting an Energy Star system and you may be eligible to recover some of your cost in rebates. A high efficiency unit has a high AFUE, or annual fuel utilization efficiency, rating.

A heat pump is highly efficient because it does not require oil or gas. Instead, it operates much like a refrigerator. It uses refrigerant to extract heat from the air and distributes it throughout the building.

An oil or gas water HVAC system utilizes a boiler to heat up the water. The warm air is distributed to several radiators located throughout the building. This type of system is not very efficient because there is a delay in the heating process because the cool air has to clear through the system after you turn the unit on and before it can distribute warm air to the building.

A gas or oil steam heater is similar to a water heater in efficiency. The fuel boils water and condenses into steam, which circulates through the pipes. With this type of heating system, you will also experience a significant delay between the time when the boiler starts and the heated air begins circulating through the building.

A system that utilizes geothermal or solar power is environmentally friendly and more cost effective to operate over time. The downside is the high cost of installation, which makes it cost prohibitive for many small companies.

Before you buy any commercial heating system, be sure to research your options and consider equipment, installation, maintenance and operation costs so you can make an informed decision about your purchase.

How Can I Save Energy With My Water Heater?

164113412Around 12 percent of an average family home’s utility bill is used for water heating. This is a huge chunk compared to the amount it takes to heat and cool spaces. If you are concerned about the amount of money you spend on water heating, then this is the article for you. Here are some tips on how you can save energy with your water heater.

Short Showers

The amount you pay for water heating will mostly depend on your family’s habits. While a warm bath will help you unwind after a long busy day, to save money on water heating, it would be better to take shorter showers. To save even more money on water heating, make a habit of turning off the water when shaving, shampooing or soaping up.

Turn Off the Water

Like many people, you probably leave the water running when performing tasks such as brushing your teeth or when grabbing dirty dishes from a different part of the room. Such activities waste both water and energy. It doesn’t require a lot of effort or time to turn off the water and turn it back on when you are actually using it.

Fix Leaks

A small leak dripping one drop of water per second may not seem like much to most people. However, when you do the math, you’ll realize just how much water goes to waste when leaks are not fixed. Small leaks can waste up to 3,155 gallons of water every year, costing you more on both water and energy bills.

Invest in Newer Low-flow Fixtures for Energy Savings

Faucets and shower heads pre-dating 1992 are not as efficient as the newer ones and will waste a lot of water. Federal regulations demand that all new fixtures have low flow rate, which ensure less water is wasted.

Invest in Timers

You can install timers which will turn off the water heater when it is not in use. For instance, you can set the timer to shut down the water heater at night or during times when you are out of the house.

HVAC System Replacement: Some Important Things To Know

man repair air-conditionerHVAC system replacement is a costly investment. So you must be on your guard when making one. First of all, you must ensure that a replacement is really required. There is no cause for freaking out if your HVAC unit registers a couple of problems. If it happens, call a HVAC specialist and let him inspect your unit and give you proper recommendation.

Having said that, units which are too old are often best replaced than repaired. First of all, repeated repairs add up to the expense and even if the unit runs properly after each repair, it will still consume much higher amount of energy than the modern units. So, even if the initial investment looks big, you will be saving up money in the long run, not to mention the improvement in the air quality and comfort of your home that a replacement will provide for.

Normally, if you find that your utility bills are escalating every month even when you have kept the thermostat settings constant; or there are fluids leaking from your system; or if it is making all kinds of irregular noises, you know that it is time to go for a replacement.

Now, once you have decided on a replacement, make sure to check on a few things before you make the buy. Contact a reputed HVAC company and ask for proper recommendation and a full estimate that will cover everything including labor and installation costs, warranty specifications, parts prices, etc.

If you have a large home or use your premises for commercial purposes, having a zoning system can be a great idea. Multiple zoning with different heating and cooling accommodations can be a great energy saver. Initial costs may be heavy, but they will pay you handsomely in the long run. So, make sure to check with your HVAC company if a zoning system is viable for your property.

Check other things as well such as the energy efficiency of the unit, what type of filters it uses, whether you will be eligible for a tax credit for the unit you are buying, also if you will need a home humidifier or dehumidifier.

What Is Thermal Comfort?

153002331Thermal comfort refers to the reasons a person feels hot, cold, or comfortable in an environment. The six factors contributing to thermal comfort create a very personal sense of what it means to be comfortable and why air temperature alone is inadequate for evaluation purposes.

The Six Contributing Factors

Each person’s body runs at a particular metabolic rate which is also affected by how active he is at any time. How much and what type of clothing the individual wears also plays a part in establish temperature. Air current (draft, breeze, etc.), high or low humidity, and/or an object giving off radiant heat affect a body’s interpretation of the sixth factor: air temperature.

Dressing in Layers

Parents tell their children to dress in layers on cold mornings when they walk to school. By lunchtime, kids are bound to become too warm for a heavy coat and mittens, but these can be removed as the day warms up or activity levels surge. Protective clothing at work, however, cannot be removed and can cause individuals to feel uncomfortably warm inside their clothing during the day.

Radiant Heat and Air Velocity

Sources such as a fireplace or oven generally create heat for those who are situated close by. The ability to retreat from radiant heat reduces the chance of overheating. Some might take this opportunity to seek a cooling breeze but that breeze can take too much heat away if one is sweaty or the air current is too powerful.


It’s surprising to people from damp, moderate climates when a very hot, dry place feels more comfortable. This is because people cannot sweat if humidity is high; they can’t cool off. Moreover, humidity often turns into rain and the necessity of wearing more clothing which adds to a feeling of stuffiness.

Heat and Metabolism

Some people feel the cold more than others, especially frail or elderly individuals. Their inner thermostat is set differently from that of other people. Although air temperature is the same for everyone, perspectives on the relative comfort of a value differ.
