The pool is an artificial structure for sports activities, medical and preventive procedures, and recreation on the water. Pools are divided into public and private, the comfort of using both of them depends on the operational characteristics of the pool, on how the pool heating is designed.
The classification of pools is diverse. By location, outdoor and indoor pools are distinguished, by the type of water circulation – skimmer and overflow, and by the type of construction – prefabricated, stationary, and SPA. But when designing any pool, the key issue is to ensure the conditions for the safe use of the structure, in particular, the heating of pools.
The pool heating system is necessary for:
- maintaining indoor temperature comfortable for water sports;
- prevention of the risk of colds due to low temperatures;
- prevention of premature cooling of water.
Private pool heating design
Methods for heating a private pool are selected at the design stage of the structure. According to SNiP 2.08.02-89, the air temperature should be 1-2º C higher than the water temperature. For indoor pools, it varies between 26 – 29ºS. If the pool is intended for SPA procedures, bathing children under 10 years old, then the indicators of the correct temperature in the pool:
- water up to 32º C;
- air – up to 34ºS.
The heating of the room in the pool maintains the established temperature regime at any time of the year.
Ways to heat the pool in a private house
The choice of heating in pools takes into account the length and depth of the structure, the type of water circulation, and other characteristics. The classic solution is radiator heating. The coolant is heated by a boiler and circulates through pipes, giving off heat through radiators. Heat transfer depends on the characteristics of radiators, their number in the room, and the temperature of the coolant.
The radiator heating system of the pool requires a pipeline and its connection to the boiler room. The air temperature depends on the quality of the boiler. A significant drawback of the system is that it does not allow for a flexible approach to regulating the air temperature in a particular room: the same temperature regime is set in each room of the house.
Therefore, for many, autonomous heating of pools in a private house is preferable. Among its advantages:
- the ability to set the desired temperature in the room, regardless of the temperature in other rooms of the house;
- increase in energy efficiency: the load on the central house heating system is reduced.
Experts often note another minus of radiator-type heating: with insufficient air circulation in the room, a non-uniform temperature is set. The walls and floor remain cold, and the comfort of using the pool is reduced.
A heating system based on the uniform forced circulation of heated air in the room helps to avoid this. Warm air maintains the correct temperature in the pool, evenly heats all parts of the room and heats the walls and floor.
Energy-efficient air heating in pool areas
The heating system must be:
- safe to use;
The use of solar energy to heat private swimming pools achieves these goals. Solar equipment is not connected to the mains, it works autonomously and without interruption. This increases its economic effect: the cost of paying bills from energy sales companies is reduced.
Since solar energy is available and free of charge, it is easy to use it to create pool heating in cottages, cottages, and houses not connected to the mains.
