Tag Archives: Installation of geothermal heat pumps

Everyone knows that I love swimming pool heat pumps. Because of their economical operation, it has allowed pool owners to swim more in comfortable water temperatures at a reasonable cost. Lately I have been fighting some customers on the best way to use the technology. When I first got on the web in 1999 selling swimming pool heat pumps, aquaculture / hydronic / geothermal and air conditioning & heating equipment most of my customers were engineers and pilots for some reason. We had great conversations and for the most part they took my advice and from the feedback I have received they have been happy for more than 20 years. As swimming pool heat pump got more  popular in the early 2000’s my customer base shifted to just about anyone who owned a pool and was cold. I felt more like an educator then a guy selling stuff as we did a lot of explaining and teaching about the best way to heat a pool. I just spent a week with a mechanical engineer who wanted to redesign the established technology and make the most efficient heat pump in the world by combining a pool heater with solar, and heat sinks, and some geothermal boost that will make the pool and the home more efficient. He was going to bury pipes in the ground combined with expensive high temperature solar panels, geothermal heat and cool for the home and geothermal and solar to heat and cool the pool. Eventually I lost him in what he was trying to do. I have seen just about everything in the field and have created some interesting combinations of technology for the fun of it at some point. Just for fun is the key as if it broke I could fix it or replace it for little money and I didn’t have small children at home in case I wasn’t around. I didn’t think it was possible to create a system that I didn’t understand. He did it though. When I told him the the temperatures that he was suggesting were to high for a heat pump and that it would blow the pressure controls he ignored me. When I suggested it was too complicated and that it is never a good idea to combine the home heating and cooling system with the pool he didn’t agree. You don’t want the pool part of the system to disable the home heating system if it fails in January when it is below zero outside. Pools can be trouble if the PH gets out of balance. That is why I like pool heaters that are made out of titanium. He was going to combine copper with chlorinated pool water and you can do that but you have to be on top of your chemicals, PH and dissolved solids. You can’t set it and forget it. So after 10 long emails he said goodby and told me he was going to create this new combination system on his own. He didn’t say he was going to take any of my advice and he didn’t want to buy anything from me either. BTW I love guys who think out of the box, but they also have to listen to others if they are going in a direction that has obvious reliability problems. I had a buddy in the early 2000’s who was a heat pump genius. He designed, manufactured and promoted a pool heater that heated and cooled the pool, heated and cooled the house and also heated the domestic hot water. I thought at the time that he had just made the world a better place. He declared bankruptcy a couple of years later. Service guys in the field had a hard time working on them and many wouldn’t even touch anything that wasn’t common. I see that more the last couple of years than I ever had in the past. Established experienced mechanics sometimes even refuse to work on brands that they don’t sell. I would fix anything my customers asked me to fix. That is what a mechanic is supposed to do. I even fished alligators, snakes and frogs out of pools and fixed some lawn mowers and kitchen sinks for my customers and I hate to fix sinks. So the more complicated you make your system the harder it will be to repair it if something happens. I know of mechanical contractors who for their own home design amazing systems to squeeze another 10% efficiency out of their equipment. I saw some great ideas. I even used a couple. They are not worried about fixing it as they can fix anything. The problem is that sometimes they don’t live forever and they have a spouse and kids at home with no onsite genius to fix anything and when the system fails nobody will touch it and the surviving family has to replace everything at a time when money might be tight or not even available. I have seen that personally. Don’t leave your family with a ticking time bomb. The efficiencies on geothermal and swimming pool heat pumps are better than they ever have been. A simple properly installed high efficiency system is usually the best way. Also simple has a better chance of not needing any service. I was at an international pool show recently. It seems that the Chinese manufacturers are going in the other direction. I saw some really cool stuff. There was a pool heat pump that heated and cooled the pool and inside the heat pump was a water pump and filter with a salt chlorinator too. It was web enabled and a couple of other functions that I forgot too. Who do you call when it breaks? There was also pool heat pump that was also a gas heater. That might solve a few application problems but who is going to work on it? I guess it depends on what part of the country or world you are in. In some places a gas guy will work on part of it. Some places a HVAC / refrigeration company. Some guys will be able to do both and in some areas their licences won’t allow them to do both. Pool contractors will be stressed too as the customer will blame them for everything. Then later if  a control that affects both systems fails they will blame each other and the customer will pay for 2 or 3 service calls. Ugh. Don’t get me going about refrigerators with wifi, inventory control and TV screens in the door or the 1980’s technology where they combined TV sets with VCRs. Whatever they are. Keep it simple and keep components separate and chances are you will have the most chance of having the least issues. Keep in mind this is coming from a guy who has a history of making stuff more complicated and have seen in the real world that it can cause more stress than benefits. Hey even I can change. 🙂

Wishing you the best as always. Marcus
