The atom, esp the v8 seems like way too much car to handle tbh. I bet it is a blast for a pro driver though.

If you're into looking at it over time on terms of costs, you're good to go. Short term, no. It's also only good down to X degrees, before you have to use a conventional heating system to keep warm. The higher your latitude, the more you're going to rely on your conventional heating method. Just as an electric heat pump is only good to X degrees

I have installed some heat pumps. No geo thermal systems yet or even being marginally involved with them. I will try to pass some things along. Even up here in eastern Canada that has become the heat pump capital of Canada.

People still buy on price here all too often. The inefficient units will always be made as they can function well enough in moderate climates. My guess is the distributors may not even handle the really high efficientcy units in moderate areas. They do cost more.

The problem with geo thermal in my opinion. Is usually the people selling them are giving the advise. There are many situations where they really should not be installed. As the soil is not good enough at thermal transfer.

I also do not think they are good for people getting up in age as the payback is too long. .You can do it with drilled wells. Not the best ideal if you have to go deep in some regions. I have a simple theory. Planned well they in general work well.

Where we reside the area conditions usually are so good. I am trying to buy an excavator. So a brother in law can do the digging and field installations.

I figured a large auction was semi rigged for one I was interested in this week. As the price realized was what I suspected it would be. The same price the last twenty units of the same model put through their auctions realised within a thousand dollars. Almost no matter what their condition was. I had mentally formed a reasonable value for it.

So I am forced to look further. I have found a 2018 cat 304 model with thirty nine hours on the hour gauge in Michigan. I will have to find the low bed trucking charge to get it up here before I try to bid it. I may also look at rail charges.

My point is the person with some experience with geo thermal. Should not be involved with selling them to you. Instead someone else estimating the practicality in your location. The first one we will be installing is in the ground water near an overflow well. The water in the ground table around it moves continually. So the heat transfer is optimum. What I am doing today and have been for sometime. Is for the benefit of our children and grandchildren.

This whole heat pump area deserves a thread of its own. The son in law has just finished his first year as a refrigeration apprentice. The guy he is working for seems super smart.

The son in law went back to school for a year at a low tuition cost of 8k first before starting. It may be the highest paid trade out there today if you really know what you are doing.

A first year apprentice gets paid little. It is more important to get you foot in the door. Where even a second year apprentice is in very high demand in this region.

I have experience with open loop heat pump,....drawing water from an oversized domestic well and discharging to a creek. It works well. Installed in 1982. I think they have replaced the heat pump once. They live in a 5 acre woods so they suppliment with burning wood. It also is a passive solar home with a two story greenhouse.

Open loop systems may develop heat exchanger issues. Water source needs evaluation before considering this approach. Especially for mineral content. Economical way to go if you have an adequate producing well though. Our home well tests at over 20 gallons a minute.

Closed loops are commonly run at about 6 gallons a minute. Our region of the province has the highest ground water levels. Except for random pockets.

They did manage to get a real increase of efficiency at colder temperatures a few years back. With the air to air systems. The four largest heat pump providers only provide it in one line of their models. I have this gut feeling they may not be selling those units in more moderate climates.

People selling these systems do not apparently understand how to act in the customers best interest and explain why. I asked a lady just reciently how she liked her newer heat pump unit replacement after it had been In a year. I asked because I knew it was a newer model and I was not feeling much output heat. It was about 16F degrees outside. She said there is little heat at about 20F degrees. I looked at the model number as I left on the outside unit.

It was a low efficiency model they sold her. Yet the high efficiency ones have been out for at least four years now. They would have been pumping out almost 100 percent of their labeled capacity at the outside temperature that day.If not a little more. . Buyers get quotes and go low price all too often. To me she got ripped off. Or did it to herself. Taking the low price quote.

They know just enough to usually buy a decent brand. Few get informed that each major brand company also has High efficiency units at much colder temperatures. The biggest name in the mini split business even just put an electric resistance heater in the head unit. On their normal products. Gets really cold outside and on it comes. I always thought it a bit of a scam.
They now produce a legitimate efficient product. I expect the resistance heater is still in their normal product line.

At 0F outside the unit I am installing on our own house will be pumping out 19,000 btus at 134 degrees. About 14,000 btus at -13F.

Although nominaly rated at 18,000 btu or 1 1/2 tons. At about 40F degrees it will produce the max of about 29,000 btus. We get about two nights at best per winter where the temperature goes as low or lower than -25F. Many years none.
]
The intent is to reduce the load and usage of the primary heating system. After I study the heat distribution from the first one I will decide on a size to install in the living room. The two pumps should carry the heating load except for a few nights each year. I have been considering also adding a two speed blower motor to the forced air system. We have a cold air return in each room I expect there to be a heat pump head. This might temper the basement temperature with the heat loss from the ducts. Nobody likes cold floors.

I believe they have an iron filter.

I had a discussion with an engineer with Dandelion Energy, which manufactures geothermal equipment. My house presents some complications which make it not cost effective, mostly related to the fact that the house was misengineered from the outset. But I can see where this could work for many suburban homeowners.

The heat source for the system is a well. The depth of the well would depend on the heat requirement of the home and the local geology. The transfer fluid is a water/glycol mixture. The wellhead and connecting plumbing are all below grade, so plant some grass and nobody will see anything. The question of neighbors: the well is obviously vertical, 500 feet deep in my case. As heat is transferred between the ground and the home, a "cylinder of disturbance" will form around the well as the season progresses. But it's only about ten feet in diameter, so unless you are very close to a property line, there will be no problem with neighbors.

A heat pump in your boiler room transfers heat between well-moderated water and R422 in either heating or cooling mode. This is then pumped through a conventional forced air system. There still needs to be a domestic hot water system, electric or whatever. And probably some sort of power backup.

Cost is initially high, because it's still early in the tech cycle and because well drilling is costly. Compared to oil heat with conventional A/C, your energy costs would be roughly half, so there will be ample cost recovery over time. There are currently a lot of private and government incentive programs (my utility offers $5000, and NYS has tax credits). Eventually economies of scale will make the cost of these systems comparable to an A/C system, plus the cost of a simple well. It seems that it's most cost effective to design a home around geothermal from day one, rather than to retrofit. Retrofitting cost would be cheapest in a house which has a single air handler which handles both heat and cooling. (This isn't the case for me, which is why it's not cost effective.) I think that if you're in a situation where you're dealing with new construction or a simple existing house, this can be a very good way to go. If I was building a new house, it would do it without a second thought.

I live in near the coast (sandy soil, high water table) and in a high-density, single-family neighborhood (0.25 acre lots). Geothermal units' performance here starts declining as the summer progresses, because the ground is getting hotter.

New high-SEER air-to-air systems are getting close to geothermal, with SEER rating of 20.

http://literature.broanhvac.net/Broan/HVAC/Air%20Conditioner%20-%20Split/FSA1BG/Technical%20Specifications/20_SEER_iQ_Drive_Ultra_High_Efficiency_Air_Conditioners_776e.pdf


As you reduce the cooling load through efficient construction, the pay-off from geothermal takes longer. That's why it's important to look at a mix of solutions, not just focus on one. Skim off only what works best from each technology... the Law Of Diminishing Returns. Similarly, going from 20 MPG to 30 MPG saves more fuel than going from 30 MPG to 40 MPG. (That's why our last car was a conventional 4-cylinder instead of a hybrid).
