Geothermal heat pumps vary in size from home to home. There are a number of factors that determine how big of a pump. Since sizing a geothermal heat pump is a intricate process you'll need to contact a qualified geothermal heat pump installer. An installer will start with an analysis of the heating and cooling demands of your home. From there he'll be able to calculate the right size system. The size of the system will dictate the size of the loop field. It is very important to contact an experienced geothermal professional before choosing a heat pump size because there can be problems with undersized and over-sized systems. A quality contractor will design the system accurately which ensures a long lifespan and low operating costs. A geothermal heat pump has the potential to save you as much as 70% on your heating and cooling bills but with an undersized system you may find yourself paying for it in both comfortSystems are generally sized in tons, an average home might be 3 tons, while a larger home might be 6 tons.

Larger systems are more expensive because of the increased size of the loop field and larger geothermal unit. If an undersized system is installed it will strain to reach your desired heating and cooling needs. This could result in high utility bills as the heat pump tries to make up for its size by using more electricity. An undersized system will prevent a homeowner from reaping the greatest benefits of geothermal: reduced utility bills.how to work ac unit Never choose your contractor based on price alone. best ac unit for a roomAn inexperienced contractor can under-size your system, thus the installation cost will be less expensive but the results will be poor. what size heating/ac unit do i needA good contractor will do their homework and correctly size the system.

You should never have an option of different size systems, there is only once correct answer! Ask your contractor how they came up with the system size, it should not have anything to do with what size system you had prior. Some people may believe that installing an over-sized system to err on the side of caution is a safe choice, but this is a misguided assumption as an over-sized system comes with problems of its own. over-sized system can produce too much airflow at a given time resulting in extremely short runShort run times cause the system to cycle on and off very frequently once again reducingA geothermal heat pump is expected to be 300%-400% efficient, but too large of a unit causes significant decreases in this efficiency. And once again, decreased efficiency results in higher electric bills. An over-sized unit will also have a negative effect on the comfort level of the occupants. the hot and humid summers a short run time will cool a room but fail to remove the air’s

While your home may be cooler it will still be clammy and sticky. of equipment operate for a fixed period of time and if the equipment is over-sized it can overshoot the thermostat setting causing a home to overheat in the winter and become an icebox in the While the geothermal heat pump equipment size is based on the heat gained and lost, the loop field depends on the size of equipment, soil type and climate conditions. To clarify, the loop field is the series of piping that is placed underground. As would be expected, the larger the geothermal system’s equipment, the larger the loop field must be. A larger loop field may mean the drill has to go deeper, the field has to be longer, or the pipes must be installed farther apart loops in order to move more heat to and from the ground. Soil type affects the necessary loop field size because different types of soil have different abilities to absorb energy. Extremely dense soils, such as rock and clay, have the ability to

hold a great deal of heat and can therefore transfer more heat. Sandy soils absorb far less heat and therefore require a larger loop field. As a general rule of thumb, the drier the ground the larger the loop field required. Sizing a geothermal heat pump is a complex process and therefore it is important to contact a qualified geothermal contractor before making any decisions. Air Conditioner Buying Guide Air conditioners can be essential in peak summer periods, making your home or office a cool sanctuary against the sweltering heat. This air conditioner buyers guide should give you the facts you need to choose the right unit for you. 1. How much power do you need? When buying air conditioners, your first consideration is likely to be how powerful the device needs to be to adequately cool your home. Air conditioner capacity is rated by BTU (British Thermal Unit) and power output in kilowatts. Buying the right size unit is very important as air conditioners that are too big will use more energy, while under-sized ones will not cool the room sufficiently.

As a rough guide, 80 watts of power per square metre should be enough for bedrooms, while living rooms may require around 125 watts per square metre. So for a living room measuring 30 square metres a unit of approximately 3.75kW will be needed. 2. Types of Air Conditioners These air conditioners are made up of two parts, with one attached to the internal wall of your home, while the other sits on the outside to exhaust heat out. These are low cost to install and with separate units for each room they provide flexibility. A reverse system refers to air conditioners that provide a cooling and heating function. The obvious benefit is that they are also useful during the winter months. Air conditioners with inverters are able to vary the temperature of the air they produce, rather than stopping and starting. They are often quieter, cheaper to run and achieve the desired room temperature more quickly – although they are more expensive. Multi-split air conditioners connect multiple indoor units to a single outdoor condenser.

They require less ductwork, but a single control station operates the whole system, meaning individual room temperatures are not possible. For more information on how to choose air conditioning for your home. 3. What sort of extra features do you need? Air conditioners with more features tend to be more expensive, but here is a list of common extras that are available: Reverse cycle for heating Slide-out chassis for easier installation Air filter to remove odours, smoke and germs Air conditioners are rated on their energy efficiency using a ten-star scale, with more stars meaning the unit is better for the environment. For units with cooling and heating functions, separate ratings are given for each. Inverter air conditioners are more energy efficient due to their ability to regulate temperature without starting or stopping. 5. Choose a professional installer Installing an air conditioner is very technical and involves many processes. In Australia, you will need to hire a licensed professional to install and service your new air conditioning system.
