How does a basement dehumidifier relative humidity sensor work?
For starters lest talk about what is relative humidity Humidity can be measured in a number of ways. These include absolute humidity, specific humidity, and relative humidity. Absolute and specific humidity measure the exact physical amount of water in the air, while relative humidity compares how much water is in the air with how much could be in the air, or in other words, with the maximum vapor pressure.
Suppose that given the local temperature and wind, the maximum vapor pressure allows a certain volume of air to hold 100 pounds of water. Now suppose that this same volume of air is only holding 30 pounds of air. The relative humidity would be 30%, because only 30% of the maximum vapor pressure has been reached.
Thus, relative humidity does not tell us how much water vapor is in the air, but rather, what percentage of the maximum vapor pressure has been reached.
Relative humidity is the most common way that we measure humidity
In either case there is a moisture sensitive component that changes its electrical properties in the presense of moisture.
Electronic circuits make use of these well defined and predictable properties to convert a variable resistance or capacitance into a proportional voltage output. For a given RH a simple transfrer function such as Voltage = (0.04 * RH in %) + .5 where voltage output would be 0.5V @ 0%RH and 4.5V @ 100%RH
Once RH is converted to a voltage is easy to use microcontrollers and ADC (Analog Digital Converters) to measure that voltage and mathematically compute RH and display is or take some action (like start/stop a dehumidifier)
I saw this video on Electric hydronic baseboard heaters watch below
While a typical baseboard heaters is true to the statement, from the man in the audience, his statement is not true.. ” a watt is a watt is a watt ” is true for electric heat, but with Electric Hydronic Baseboard Heaters the interanal parts are oil filed and the oil in side gets so hot that it contiunes to heat even when there is no power going to the baseboard heater… The baseboard system cools slowly, continuing to retain heat and generate warmth, even after shutting off making it more energy efficient that a standard baseboard heater…

element is completely submerged in heat transfer fluid totally sealed in a copper tube spanning the length of the heater. Heat is transferred evenly across the entire length of heater. Even after thermostat is turned off, soft warmth continues to radiate because of maximum heat retention of the hydronic element.
Electric baseboard heaters are powered by electricity as opposed to natural gas or oil. The heating element inside every electric heater is simply an electrical resistor – when the heater is on, electric current cause’s resistance heating up an element. A baseboard heater is a type of convection heater. It heats up and spreads its air through metal fins, warming the air directly above and around it. Hot air spreads out, becoming less dense and rising into the air. This creates a vacuum, pulling cool air towards the baseboard heater and starting the process over again. This creates a continuous current of air called a convection current. Once the convection current gets flowing, it can spread heat to the entire room.
Electric Baseboard Heaters come in either 120 or 240 voltage. It’s important to have to correct voltage – if you have question on voltage please call us or consult your electrician.
- 120 volt wall heaters come in wattages ranges of 500 to 1500 watts
- A 120 volt heater can only heat a room 50-150 sq ft a room bigger them you will have to go with a 240 volt model
- 240 volt heaters range for 1,000 to 4,800 watts
- If you wire a 240 volt heater to a 120 volt circuit, you will only receive about ¼ or 25% of the wattage the heater was designed to deliver
- If you wire a 120 volt heater to a 240 volt circuit the heater will overheat and self-destruct! The heater will try to deliver four times its rated wattage, causing the element & the motor permanent damage.
- You may also have heard of (110 volts, 115 volts, and 125 volts) – they are the same as 120 volts. Also, (220 volts, 230 volts, and 250 volts) are the same as 240 volts.
Baseboard heaters can be controlled by a built in or wall mounted heater. Built-in thermostats (mounted directly on baseboard) are designed for single heater use. However, it is possible to control more than 1 heater on a wall thermostat if the thermostat rating is not exceeded. (Check the thermostat or instruction guide for thermostat rating.)
If you are fond of gardening you would wonder what things you would need to build up your own garden. You would consider what plants and vegetables or flower tress that you would love to decorate your garden with. You might feel at some instance, hey does that need so much of research? But you need to definitely ponder on certain points before you fix what plants you would buy for your garden. Some trees and plants grow in specific area only. The nurturing feature for the plants is their position in the garden and amount of sunlight they get.
You need to think about what kind of garden you would like to establish. You may choose small botanical garden setup or opt for all sorts of big and small trees. The increasing pollution has led to many health issues. By growing trees you would contribute towards conservation of the environment. The trees would provide your garden natural shade where you can chill down when you are back from all days work. Although having many trees is fascinating idea however don’t overgrow no of trees as that would leave place for you to walk in the garden.
If you have a huge area where you are planning to build up your garden you can choose huge trees like pine trees as well as oak trees. If the area for garden is too small then don’t choose huge trees as they might fall over and create unnecessary havoc. With limited area available choose smaller trees in this case. In whatever might be the dedicated area, choose rapid growing trees that would fill up your garden.
Speaking about tree growth, the growth of the trees is determined by the sunlight they get. The food produced by food is carried out through the process called photosynthesis. Each and every tree or plant has its own requirement and intensity of light required to grow the tree. There are many growing tents available in market that can be used to grow the trees. These grow tents are designed such that they provide the environmental conditions that favor the growth of the trees.
If you are planning to provide shade to your garden the shade color should be such that it doesn’t block large amount of sunlight. This would hamper the growth of the trees in the garden.
Once you are done with the plantation, trees and plants keep on growing for years together. There is certain caution- point that you need to consider. Every tree needs its own soil area to grow without any constraint. Overcrowding trees would not allow them grow easily. At times if you have bushes like trees you can trim them to give them attractive shape. Regular pruning helps in maintaining the beauty of the garden. Regular spraying insecticides should be done to avoid plants getting infected by some insects attack.
So what are you waiting for? Get digging and plowing. Rush to markets and buy trees of your choice and renovate your garden in a beautiful manner!

One of the most important appliances at home is your water heater, that’s why you need to have a water boiler for your water heating services. If you want to install a new boiler, either because the old one is becoming ineffective or maybe its past the stage of any reasonable repair, there are several things you need to know, this will help you adequately prepare for your installation.
The first thing you need to know is when is the best time to have your boiler installed. The engineers will need to access your house, this is done possibly for a few days, and so make sure someone is available at home for the whole time.
It’s advisable to have the boiler installed during summer rather than winter. This is because you are more likely to get an engineer to fit around you this time of the year, since obviously fewer boilers breakdown in the summer and so engineers may have more time.
You also need to know which boiler you should have. There is a lot of choice out there. Spend time thinking about what you really need. You also need to consider, especially if you want to carry out a home improvement project, it’s important that you plan on what type you want. For example a combi boiler could free up a lot of space in your property.
You need to carefully choose who will install your boiler. Typically a boiler works by converting natural gas into heat energy, the heat energy then converts water into steam. A single mistake or skipping a step in the installation process could lead to disaster, it’s therefore very important to use the services of a registered engineer. This way you can be certain that the engineers are able to appropriately fit your boiler efficiently and safely.
Do some research into various area companies that perform boiler installations. Take your time and ask friends, family and also go to the internet to look for reviews. From this you will be able to make an informed decision about who to work for you.
Where is the boiler going to go? You also need to know this. Keep in mind that the boiler should be installed as close as possible to your gas and water lines, as both will need to be connected to the boiler. Minimizing this distance will save on the materials and labour the installation requires. If you have many boilers, they can be positioned outside, this will free up space in you’re your home and reduce noise.
The price of installing a boiler is one thing you should keep in mind. A new boiler can be expensive to buy, so have to weigh up the prices available. It’s very important for any new boiler to consider a scheme or payment plan which will allow you to spread the cost over a longer period. Look into the different ways to make payments, then choose the right one for you. This can be the ideal solution if you want to replace the old boiler under limited funds.
Most would agree that their air conditioning and heating unit is the lifeblood of the home, much like their water and electricity. Without cool air in the summer and warm air in cooler months, our homes would be uninhabitable.
Knowing this, responsible homeowners tend to take care of the obvious preventive maintenance chores themselves, such as checking and changing air filters or keeping their thermostats set at a consistent temperature. They unblock inside ducts and vents inside the home to assure proper airflow. Many even know to keep grass trimmings, leaves, weeds and foliage away from outdoor heating exchange units.
While all of these measures are helpful, it is imperative that you also have a strong HVAC preventive maintenance contract in place for a more in-depth inspection and tune-up from a licensed professional HVAC technician. The word “preventive” means to keep something harmful from happening, so these maintenance agreements are not just a wise option; it is a crucial step in prolonging the life of your system — the lifeblood of your home.
What Are the Advantages of Having an Air Conditioning and Heating Contract?
• They guarantee that your equipment continues to function properly and remain in good repair. Bi-yearly inspections in the spring and fall ensure that minor issues are caught before they become expensive problems in the dead of winter or on a blistering hot day.
• They save customers untold amounts of money; they can boost your equipment’s energy efficiency by as much as 30 percent. The eventual cost difference between a well cared for HVAC system and a neglected unit is astronomical in terms of energy use, repair or replacement.
• They eliminate unacceptable surprises. Customers with a maintenance agreement rarely are hit with a midsummer air conditioning system replacement when failing or faulty equipment is detected beforehand. Remember, even an unsafe heating furnace will still heat your home. If something dire is found ahead of time, your HVAC technician can help explore your options.
• They are convenient and eliminate hassle. You contact them on your time schedule when it’s time for a checkup. Additionally, rest assured you will receive priority status should you need immediate service. Furthermore, you can be certain that your NATE-certified HVAC technician knows your air conditioning system inside and out.
Without a Preventive Maintenance plan, costly repairs will most likely come sooner than they should. It is not just a case of “pay now or pay later.” The reality would be closer to “pay now or spend considerably more later.”

There was a time not too long ago that words “heat pump” and “environmentally friendly” did not go together at all. Heat pumps had a reputation for being terrible for the environment and for being a horribly inefficient way to heat and cool your home. All this has changed, however, thanks to government requirements for heat pump efficiency. The heat pump manufacturers have long since met these government regulations and surpassed them. These days, heat pumps are known as the environmentally friendly choice for home owners. How have things changed so much? Much of it comes down to how heat pumps work.
First, consider how central heating and cool systems function. They take air and then heat it or cool it to the temperature you require based on the temp you have set your thermostat at. The systems require an energy source to get this job done. That means your central heating or cooling system needs the energy from your electric system or gas/natural heat system – sometimes both. It comes as no surprise to anyone with one of these systems that the energy used is significant. Running your heating and your air conditioning can increase your power bill by hundreds of dollars every month. In addition to being a drain on your wallet, these central systems and the energy that they use are a drain on the environment.
Now, consider heat pump technology. Heat pumps do not use energy to heat or cool air to any temperature. Rather, they simply shuffle air back and further. During the winter, heat pumps take the warm air from outside – and even if you can’t feel it, there is hot air in the air on the coldest days – and it pumps that warm air into your home until the thermostat reaches your desired temperature. During the summer, a heat pump works in reverse. The pump takes the warm air from inside of your house and pumps it outside, until the internal temperature reaches the desired level of coolness. Because the heat pump is not heating or cooling anything using electricity or gas, the energy operating costs are much lower. And because less energy is used, the impact of running a heat pump is far less on the environment than running a central heating or cooling system.
All heat pumps are not created equal, however. If you live in an older home and your heat pump predates the government regulations, then it still may be terribly inefficient. Even new heat pumps can vary greatly in terms of their effectiveness. Also, heat pumps are not efficient in climates with extreme temperature swings.
All things considered, however, heat pumps are ideal solutions for environmentally friendly heating and cooling.
A standard air conditioner does remove moister from the air, but its first concern is cool the air. To explain this I need to cover dry heat vs. wet heat. Dry heat or (sensible) is what you feel from a light bulb. Dry heat is tolerable for a short time, if you remove food your oven the air is 450F. It’s hot but tolerable if you try and put your hand in 450F boiling water you see what hot really feels like.
Humidity holds a lot more energy than dry air, therefore remove water is much harder that cooling the air temperature. An air conditioner will cool the air and leave most of the moister in the air. A dehumidifier has a lot more surface area so it can dry more efficiently. So back to our question if your air is cool but moist you will need a dehumidifier to dry the air.
A room that’s 60% relative humidity or higher you’re going to have a mold / mildew problem that an air condition will not fix. If the room is at your desired temperature the air conditioner will not operate to dry out the air. An air conditioner only cares about room temperature not humidity. A dehumidifier only cares about humidity and not room air temperature. So sometimes you need both units to run at the same time in the same place.
