Long before Geothermal Heat Pump was invented, people had used geothermal energy from natural hot springs. This trend could still be found today. In 1852, Lord Kevin invented first heat pump prototype. Then in 1912, Heinrich Zoelly made the heat pump extracted heat from earth. It was not until 1946 that Donald Kroeker managed to draw whole heating system.
In modern days, people have no problem to get access to electricity and gas, so why they want to pay Geothermal Heat Pump cost? There was time when companies had troubles to supply carbon. This is when renewable resources kick in. Some countries even provide subsidiary fund for their citizens.
A lot of people still have misconceptions about geothermal heating. This is by far the most popular topic reviewed in Geothermal Heat Pump reviews. People think that the system is only for heating. This is not true! Geothermal Heat Pump (GHP) works just well for both heating and cooling.
What Is Geothermal Heat Pump
Another name for GHP is geoexchange. People set their eyes on it as alternative heating option. This machine could provide both clean and efficient heating and cooling system. Unlike normal heat pump that works really hard to extract heat during winter, natural heat is always available.
Therefore, GHP works by transferring heat into houses or extracting heat from the houses. In order to allow GHP machine to run its system, you need electricity. Don’t worry too much; it will not cost a lot. Remember: energy needed for heat transfer is always less than energy to collect or extract heat.
In the end, GHP will help to provide alternative lasting sources for heating and cooling purposes. Modern invention found a tool to distribute heat waste to water pipe. Those who install this system will get double advantages; heat pump function and never ending hot water. Aren’t those offers too good to ignore?
Pros and Cons of a Geothermal Heat Pump
When heat pump system has been installed, people still need to pay the running costs. These include electricity and gas bill. People try to compare conventional pair of heat pump and gas furnace to GHP. The result is quite shocking; GHP saves up to 50% for gas and 35% for electricity.
Buyers who take GHP love the energy source. Instead of relying on non-renewable energy, GHP makes use of long lasting and readily available energy. In addition, people would not harm their own environment for the sake of personal comfort.
Besides geothermal, people have some proposals from other renewable energy sources. They are wind and solar. However, geothermal is more appealing. Why? It is because both wind and solar power are not available all year long.
Buyers could save money after installation, not before. Installing GHP to a house require a lot of supplies and meticulous calculation. Otherwise, GHP might not function properly. Bad news is the total costs of installation are quite high. In some cases, it is even higher than buying top brands’ products.
As mentioned above, buyers cannot directly install GHP to their houses. A geothermal line should be created, which often require water system adjustment. Also, not all houses have adequate ductwork. In order to install this, buyers should add $3000 more. Moreover, buyers might be in line, as less contractors have good standardization.
Geothermal vs. Air-Source Heat Pumps –
Buyers need to consider several things before buying GHP. They shouldn’t be too happy with energy saving factors to forget about the preparation costs. It includes the price per unit and also installation costs. Keep in mind that GHP might require total reformation of the house. If buyers will stay there for years, then it is a great investment.
On the other hand, those who love to move around might want to take air source instead. This portable system could fit into any housing without too much renovation. Also, it costs less than installing a GHP.
This is probably the main reason why buyers take GHP into consideration. There is no way air source heat pump could beat GHP in terms of efficiency. Put these two under extreme weather. GHP will work on 300 to 600 percent efficiency. At the same time, air source heat pump is struggling to keep up with 175 to 300 percent efficiency only.
Buyers could tell that air source heat pump has two units; indoor and outdoor. It means that outdoor unit will eventually break after bad weather or small debris. On the other hand, GHP keeps every unit either indoor or underground.
Geothermal Heat Pump Costs Factors
Presenting buyers with high price is never an easy job. However, more and more people appreciate value over some cheap stuff. In addition to total bill, buyers deserve to know in details about the spending.
Any house that will use GHP requires ductwork. This will be the first thing to inspect. Thankfully, houses with pre-installed ductwork won’t need to install additional ductwork. In some cases where ductwork is not enough, then contractor will remove the entire setting. Additional cost for ductwork installation might be included for new house or houses with broken ductwork.
Another factor that affects GHP cost is size. Bigger house will cost more. Why is it so? A standard house of 2000 square feet will need 3 ton system. Now imagine similar house with two or three stories. For sure, buyers will pay higher than one story house.
All outdoor tools for GHP are buried underground. They will later work on a loop field. Again, bigger size building require bigger loop field. In short, buyers’ front yard or backyard will be dug out first. In addition to house size, colder or hotter climate might add the depth of loop field.
Think also about soil type. Things will be easier if buyers know the topology of their area. Otherwise, they might have to pay soil testing. It costs $1300. Buyers should play safe when they don’t know the soil type. Contractors might demand additional money if they have to break concrete or stones.
Geothermal energy could also be found in lake or river. Thus, people might want to connect the loop to this heat source. Be careful while doing it. Usually government has specific regulation related to lake or river exploitation. Consult local government for further details before preceding the setting.
Geothermal Heat Pump Costs and Brands
Please note that there is no option for “cheap” GHP units. In order to differentiate performance level, only two categories are presented; moderate quality and premium quality. If buyers are after valuable items, then the options should be among moderate quality ones. Those who want top efficiency should only look at Premium Quality options.
Moderate-quality brands and average costs
There are nine brands that belong to this category. The lowest price per unit is around $2000 and highest price reaches $7000. First recommendation would be Bosch.
Buyers should prepare $3000 to $4000 to buy a unit. Second suggestion in the line is Century. The cheapest model costs around $2500 and the priciest unit costs around $4000.
Here are some other brands worth to try:
1. Daikin: models’ price; $3200 to $5400
2. First Co: models’ price: $2400 to $3500
3. GeoCool: model’s price: $2500 to $7000
4. GeoStar: model’s price: $2300 to $3900
5. Geomax: model’s price: $2700 to $4600
6. Hydro Royal: model’s price: $2500 to $3500
7. Nordic: model’s price: $2300 to $4000
Premium-quality brands and average costs
For best GHP performance, buyers should ask for premium quality product. It offer higher efficiency and lasting tools. There are three brands that could provide GHP unit under $4000 for its bottom tier units. They are Miami HP, Modine and MARS. Miami brand will cost buyers $2600 at the lowest and $7300 for its fanciest unit.
Modine models range from $3000 to $6200 per unit. Of course, buyers could compare these units first before buying them. Last option, MARS, offers slightly higher price for its bottom unit but more affordable price for top unit. It ranges from $3200 to $5000 per unit.
Several top brands buyers could look at:
1. Bard: model’s prices: $5000 to $7500
2. Carrier/Bryant: model prices: $4000 to $6600
3. Climate Master: model prices: $4000 to $6500
Supplies and Installation Costs
In addition to unit’s price, buyers should also calculate the cost for buying supplies and paying contractors. Every house will have different total for supplies and installation. It is because each house has special needs and condition. Therefore, manual calculation should be done.
Supplies to Build GHP System
There are several tools and substances that should be bought prior to installation. They are pipes, PVAC glue, anti freeze and anti corrosion chemical. Buyers should measure house size perfectly so they won’t buy too much or less than needed. Usually, this cost from $1200 to $3000 per house.
Don’t be surprised with the bill. Contractors need to dig quite deep to ensure safe GHP installation. Thus, they will need heavy equipment such as well drilling truck.
Add also the costs for workers. Choose installation time carefully; bad weather might delay the work and double the costs. Prepare around $6500 to $14000 for the entire system installation.
