ᐅ Building a Pool at the Same Time as the House - Your Opinions?

Dear community,
Since December 2020, we have been planning our house and reached an agreement with a provider in April. See:
https://www.hausbau-forum.de/threads/erste-grundrissplanung-auf-karopapier-hang-keller-2-geschosse.37567/
During the planning, the topic of a pool was always in the back of our minds and was discussed several times. Our initial feeling was "let’s build it right away," which over weeks and months shifted to "preparation now and realization later" for the time being. Now our direction is changing again, and we are researching construction and maintenance costs. Since it is difficult to assess the reliability of the various sources, or they do not align with our idea, we would very much appreciate feedback from the community here.
We are looking at a pool size of 8 x 4 meters (26 x 13 feet) without a counter-current system but with an electric cover. We are not entirely sure about pool heating. The technical room is located in the basement near where the pool will be installed.
We keep telling ourselves that building the pool now would be much cheaper because pool and house work could run in parallel, creating synergy effects (economic and legal aspects included 😉 ) regarding earthworks, foundation, crane use, and technology.
Our questions are:
1. In general: What do you consider to be the best type of pool for our project? We know the pros and cons of various types but cannot come to a final conclusion.
2. How much would you estimate the pure construction costs of your “preferred option” under the above conditions?
3. How large do you estimate the price difference between “building now” and “doing it in xx years” to be?
Thank you. 🙂

When it comes to a heat pump, the KFW funding should not really be an issue. The heating capacity is calculated without the pool.
I am rather skeptical about whether you can get a unit with indoor installation in that performance class.
Therefore, I would recommend using a separate heat pump. This way, you won’t have any problems with KFW or anything else.
We are talking about 31.2 m3 (1101 cubic feet) of water. The heat pump should have at least 20 kW (27 hp). Otherwise, it will take you weeks to warm the water and you will not be able to maintain higher temperatures when it gets colder.
Choose the automatic backwash. Even if the filter is not dirty, it should be backwashed weekly. Otherwise, channels will form, and the filtration performance will decrease. Also, the material usually needs to be replaced earlier.

The first thing all the plumbers said was that the pool must have its own heat pump; otherwise, it doesn’t make sense in terms of performance. Since I am not responsible for the technical details, I can’t explain the exact calculations.
We deliberately decided not to install the pool equipment inside the house. Some acquaintances had a minor water damage caused by a faulty lifting station, and even though it was only a few liters of water, the drying process—including drilling into the screed—was very complex. Because of that, we were uncomfortable with the idea of running the pool water through the house. Except for one pool builder, everyone else also recommended not placing the equipment inside the house for these reasons.
In any case, I would definitely choose an automatic backwash system; nothing else was an option for us, especially since we sometimes forget to check it on our current pool.

Costruttrice6 Aug 2021 12:27If I remember correctly, we would have needed a significantly larger heat pump for the house, and there was something else related to the cooling function, but I can’t quite recall the details.
Our friends had a sensor installed on their lifting station that gave an alarm, but unfortunately no one was home at the time, and eventually it overflowed.
Technically, this is definitely possible and much safer, especially for a pool, but the effort wasn’t worth it to us. And if someone – or rather a woman – has a bad feeling about it, there’s no convincing them otherwise. We are now combining the utility room with the garden shed that is already there; I wouldn’t have wanted to have a separate shaft for the equipment.

He recommended the larger heating system instead of an additional heat pump, but also expressed concern that this might affect eligibility for KfW funding due to poor energy consulting. Do you have any gut feelings about this?Calculate how much the KfW funding really benefits you overall, and how much extra effort and money you need to invest to achieve this. It’s not without reason that many people disregard this funding and choose not to apply. (That’s also the case for me.)Similar topics
