What are the different heating options for Drop?

Drop pool can be used in a variety of ways. Selecting the correct heating is the most important decision when you are purchasing an outdoor pool. You can consider the easiest and most convenient option for you and whether the pool will be, for example, at the summerhouse or your backyard.


Stove – Drop Black Box is our new and efficient 35 kW stove that heats the pool water in approximately two hours. The stove is made of durable ocean aluminium and can be used with sea or lake water.


Electric heating – with a 3 kW or 6 kW electric heater, the pool can be kept ready to use so that the water is always at the desired temperature. Together with the insulation, electricity consumption remains extremely low, at approximately 3000-4000 kWh per year in Finland when the water is kept at 37 degrees Celsius around the year.


Geothermal and district heat – with the heat exchanger, you can connect your Drop pool to your house’s geothermal or district heating system. The heat exchanger, pump, outlet hoses and thermostat are provided by an HPAC fitter to make sure they fit with your house’s system. Ask for more information from our customer service!

How long does it take for the water to heat up to the desired temperature?

Stove 35 kW: 1-2 h


3 kW electric heater: heats the water approximately 1–2 degrees Celsius per hour.

6 kW electric heater: heats the water approximately 3–4 degrees Celsius per hour.


Electrically heated pools are meant for year-round use, so you do not need to heat the pool from cold water (approximately 5 degrees Celsius) to the desired temperature. You only need to heat the pool when you first start using it and when you change the water.


What are the electricity costs of an electrically heated Drop pool?

The electricity consumption depends on things such as insulation, utilisation rate, the weather and your electricity contract. Together with our first-class insulation, electrically heated Drop pools consume approximately 3000-4000 kWh per year in Finland when the water is kept at 37 degrees Celsius around the year.

Can the Drop pool be used in the winter?

We recommend that you use the electrically heated Drop pools even in the winter — after all, Drop pools are meant for year-round use! The technology of a pool with maintenance heating is safe from cold weather inside the insulation of the entire frame. The most important thing in maintaining the pool in the winter time is to make sure the pipes and technology never freeze. Stove-heated pools can be used normally in the winter. However, when emptying the pool, make sure that there is no water left in the pipes or stove. Please note that heating the pool in the winter may take longer than usual.




Where should I place the Drop pool and what kind of a foundation does it need?

The placement of the pool should be planned as carefully as possible to ensure comfort of use and safety. Place the pool in an open area, if possible. Otherwise, leaves and other dirt falling from trees will easily end up in the pool water during bathing. Consider your neighbours if you live in a densely populated area.


The pool must be installed and rely on its framework. The pool should not rest on the upper edge, and the upper edge should not rest on the patio, for example. The base functions as a capillary break between the earth and the frame. The foundation must be even, load-bearing and horizontal. The best foundation is concrete, gravel, wood or some other hard foundation material. The foundation must endure a weight of 2,500 kg without sinking or changing. In addition, consider the impact of frozen ground when planning the foundation.


The placement of each pool must be planned according to situation and place. The blueprints are indicative examples of installation.

How is the Drop delivered?

The pool is delivered upright by a lorry to the delivery address provided by the customer or as close to the delivery address as possible. The driver will lower the package with a pallet jack. The pool package is upright on top of a pallet.


The pool package has a freight weight of approximately 135–300 kg, depending on the extra features.

How is the Drop pool filled with water? How much water fits in the pool?

The Drop pool does not need a separate water connection as it can be filled with, for example, a garden hose.

The pool’s capacity is 1,830 L. In practice, only 1,000-1,500 is needed to fill the pool.

How much electricity does the Drop pool need?

The Lähde pool with a 3 kW electric heater and no extra features consumes 1 x 16A.

The Vuolle pool and Lähde with extra features consume 3 x 16A.

We use geothermal heat; how is it connected to the pool?

The heat exchanger needs its own heating circuit, or it can be connected to a radiator network circuit, depending on the design. The idea is the same as adding an additional radiator to the heating circuit. With geothermal heating, you pay more for the maximum efficiency at first, but it will pay for itself with time.


Considering the warranty and installation of the heat exchanger, the importer/producer is liable for the pool and equipment delivered with it. Fitters are liable for the installation. If you use geothermal heating, an HPAC professional must always be used because the system will be connected to the house’s own fixed heating system. The heat exchanger, pump, outlet hoses and thermostat are provided by the HPAC fitter to make sure they fit the house’s system.

Maintenance of the water


How is the Drop pool emptied?

Electrically heated pools are emptied with a pump.


Make sure that there are no embers left in the fireplace before emptying the pool. Empty the fireplace of ashes before emptying the pool of water. The stove must also be emptied of water by using its own outlet valve.


N.B.! If you use chemicals in the pool water, the water must be led to the sewage system!


How is the pool water kept clean?

If the pool water is not changed after each use like you would do with a pool heated with a stove, you must make sure the water stays hygienic.

A pool always requires a bit of maintenance to keep it fresh and clean. The filter and UV systems alone are not enough to keep all bacteria away.


Change the pool water approximately 3 times a year, depending on the usage.

Change the filter balls approximately once a year.

Add chlorine tablets or active oxygen granules regularly; for example, once a week or after each use. Adjust the water’s pH value when necessary. Always follow the dosage of the chemicals.
