Calculator for calculating underfloor heating and heating systems. Unload the radiator heating system of the house or completely replace it; with sufficient thermal power, the water heated floor will be enough to compensate for heat losses and heating the room.

How to calculate a warm water floor online? Water floors can serve as the main source of space heating, as well as perform an additional heating function. When calculating this structure, you need to decide in advance the main points for what purpose the product will serve, to fully provide the house with heat or slightly heat the surface for comfort in the room.

If the issue is resolved, then you should proceed to drawing up the design and calculating the power of the warm water floor. All mistakes that will be made at the design stage can only be corrected by opening the screed. That is why it is so important to make the preliminary calculation procedures correctly and as accurately as possible.

Calculation of a warm water floor using an online calculator

Thanks to specially prepared online calculation systems, today it is possible to determine the specific power of the warm floor in a few seconds and get the necessary calculations.

The calculator is based on the method of coefficients, when the user inserts individual parameters into the table and receives a basic calculation with certain characteristics.

By entering all the specified coefficients, you can obtain the exact characteristics of the calculated underfloor heating with maximum accuracy. To do this, you need to know the data:

• water supply temperature;
• processing temperature;
• pipe step and type;
• what kind of flooring will be;
• screed thickness over the pipe.

As a result, the user receives data on the specific power of the structure, the average temperature of the obtained floor heating, and the specific consumption of the heat carrier. Profitable, fast and extremely clear in a few seconds!

In addition to the basic data, a number of minor ones should be taken into account, which have the maximum effect on the final result of the warm floor:

• the presence or absence of glazing of balconies and bay windows;
• the height of the floor of the premises in a residential building;
• the presence of special materials for wall insulation;
• the level of thermal insulation in the house.

Attention: when calculating a warm water floor using a calculator, the type of flooring should be taken into account, if a wood structure is planned to be laid, then the power of the heating system must be increased due to the low thermal conductivity of the wood. With high heat losses, the arrangement of a warm floor as the only heating system will be inappropriate and unprofitable in terms of costs.

Features of calculating the water floor with a calculator.

Before making a preliminary calculation of the water floor heating system, a whole list of features should be considered:

1. What type of pipe will the master use, corrugated with effective heat transfer, copper, with high thermal conductivity, cross-linked polyethylene, metal-plastic or polypropylene, with low heat transfer.
2. Calculation of the length for heating a given area is based on determining the length of the circuit, the distribution of heat energy over the surface in a uniform mode, taking into account the limits of the thermal load of the coating.

Important! If you plan to do a larger laying step, then you need to increase the temperature of the coolant. Allowable step indicators are from 5 to 60 cm. Both constant and variable steps can be used.

Beginner mistakes - professional recommendations

Many users of the online calculator for calculating a water-heated floor make significant errors that affect the final results. Here are some user errors:

• A pipe with a length of no more than 120 m is designed for one circuit.
• If there are warm floors in several rooms, then the average length of the contour should be approximately the same, the deviations should not exceed 15 m.
• The distance between the branches is selected in accordance with the temperature regime of the heating system, most often it will depend on the region of the territory.
• The average distance from the walls to the contour is 20 cm, plus or minus 5 cm.

What do you need to know when going for the necessary building materials?

Extruded polystyrene foam is the best material in the case of floor insulation, it is distinguished by its durability and solid structure. On top of the insulation, waterproofing should be laid, a plastic film will be enough, and a damper tape should be laid along the walls.

The fittings are the basis for fastening pipes and concrete screed, pipe clamps are another indispensable element. You should also take a distributor manifold, which will allow you to economically and efficiently distribute the coolant.

Conclusion

When calculating the water floor online, you should take into account the coefficient of data discrepancy by 10%, in this way the obtained data will be more real and reliable.

Good luck with your construction work!
