The Types Of Heat Pumps | About Installation And Overall Cost

Heat pumps generally transfer the heat from various sources of heat. Many times it happens that the temperature inside a room gets very low that one can not survive. Sometimes people who live in that kind of surroundings want that place to be warmer. At that time, the heat pump comes into role. The heat pump can make the room temperature moderate.

The Types of Heat Pumps | About Installation and Overall Cost

All refrigerant systems including heat pumps rely on the refrigerant’s pressure-temperature relationship. When a refrigerant evaporates or boils, it absorbs heat at a very high rate as it is the case with all liquefied gases. Since refrigerants have a lower boiling point than most liquids, we can easily manipulate them and the room temperature air becomes the only heat source we require. By altering the pressure placed upon the liquid, we can control this boiling point.

How Does A Heat Pump Work?

Now let’s take a look at the operation of a common split system air source heat pump. In the summer, the compressor inside the heat pump receives cool low-pressure refrigerant vapor and it pumps this vapor into the high-pressure side of the system. The hot gas produced passes via a routing valve (which is also known as reverting valve) and moves to the outside coil that works as a condenser. Through outdoor fan, the heat is removed. As the refrigerant gets evaporated, it starts absorbing heat from the passing air. The refrigerant then goes back to the compressor – where the cycle is repeated again.

While in winter mode, the reversing valve changes the refrigerant path. So, at that time the outside coil functions as an evaporator & indoor coil work as the condenser. Heat absorbed by evaporator from the outside air is then brought inside the room’s air.

Basically, there are 4 main types of Heat Pumps:

Air-to-Air, Geothermal, Water Source System, and finally the Exhaust Air System.

1. Air Source Heat Pumps

It works the opposite way to a fridge from a technical perspective. What it’s doing is taking energy out of the air even at very low temperatures. So even down to sort of minus 20 minus 30 degrees, there’s still energy in the air and the way it works is by pulling the air through a fan and is actually heating a refrigerant that boils at a very low temperature. Then pushed through a compressor that that heats it further creates temperatures of up to about 60 degrees which you can use to heat your water and your radiators or your under-floor heating system signs it is designed so that we can provide all of the heat and all the hot water for the house. A heat pump is like a big fan. When the system comes on, you’ll see that fan turning it’s very quiet you can only hear it. When you’re pretty close to it but so if you get too close you can feel the cold air coming off it as it’s sucking the air in taking the heat out of it and throwing the cold air out.

2. Geothermal Heat Pumps

If you can enjoy the cool atmosphere in the summers, warmness in the winters and also get hot water throughout the year, but how is this possible? The answer is geothermal heat pumps. These heat pumps make use of the abundant amount of energy which is almost constant at all times present below the earth. The energy is just a few feet below the ground, and it is then used for both heating and cooling the buildings.

3. Water Source Heat Pumps

Water source heat pumps are an efficient method of heating and cooling. An entire building that has this type of heat pump is named for its ability to produce warm and cool air from the water system. The unit is connected to water source units that are compatible with chillers/oilers earth loop and hydronic systems. They are low maintenance and are quiet during operation as they are built with a rotary compressor. The water source console is often used for the hospitality industry, hospitals and assisted living facilities. The cupboard is often made from galvanized steel with a powder coating for long-lasting durability and corrosion resistance. These systems are for retrofit and new construction applications which include the chassis and a front cover that’s attractive in appearance and fully insulated on the inside for quiet operation. We can control this water source apparatus easily through wired also like the wireless wall thermostat

4. Exhaust Air System

Using this system you could get the heat extracted from the exhaust of the building to the hot water system or the heating system in use. This requires at least mechanical exhaust; however, mechanical supply is optional. This type of warmth pump requires a particular air rate of exchange to take care of its output power. Since the inside air is approximately 20 – 22 C. All year around the maximum output power of the warmth pump isn’t varying with the seasons and outdoor temperature air leaving the building. When the heat pump compressor is running – it is usually at around minus 1 degree in most versions. Thus the unit is extracting heat from the air that needs to be changed at around ½. Also, you must take special care of using this system for the right kind of house. There will be a low heat output to the hot water and heating is just around 1.2 KW from the compressor/heat pump process but if that falls short of the building’s requirements. Additional heats are going to be automatically triggered within the sort of immersion heaters or an external gas boiler.

The immersion heater top-up will be substantial and when the unit with a 6 KW immersion heater operates at full output, it will cost 1 per hour to run a newer version.

Do You Save Money Using A Heat Pump?

Yes, you can!
1. A heat pump can help save you money, many splits, help drive energy savings, reduce home heating costs and lower your impact on the environment.

2. Heat pumps offer energy savings because rather than creating the heat on its own it takes it from the outdoor atmosphere and circulates it throughout the home.

3. Heat pumps can help reduce your energy usage by up to 50% versus other home heating systems.

4. Your expected savings will vary based on the current heating system that you’ve got, the local climate, the going rate of fuel and electricity and the size and efficiency of your installed heat level.
