How many meters of pipe do you need for underfloor heating? Calculation of the length of the underfloor heating pipe.
Underfloor pipe length (L):
N if the distance between the pipes (pipe spacing) is 20 cm, then you enter 0.20 in the calculator, if 30 cm it is 0.30 and so on.
L = ((S/N)*1,1) + (l*2)
L - the desired length of the underfloor heating main
S - room or contour area (m2)
N - pipe spacing (distance between pipes, m)
1.1 - pipe stock factor (through bends)
l - the length of the pipe to the collector (m)
For example. The area of the contour, room or room (S) where the heated floor will be installed is 17 m². It is assumed that (N) the distance between the outgoing pipes will be 0.20 m. The distance (l) from the collector connection point to the room or room where the underfloor heating will be installed is 3 m.
L = ((17 / 0.2) * 1.1) + (3 * 2) = 99.50 m.
Let's say if the room is 30 m², and the underfloor heating will occupy only 16 m², then S = 16 m².
The calculator calculates ONLY the length of the heating pipe required for one room. If you need it for the whole house, you calculate separately how much is needed for each room, and then you add the lengths obtained to know how much pipe you need in total.
Underfloor heating maximum pipe length
Maximum pipe length for underfloor heating. When installing underfloor heating in a room the maximum length of pipe in one loop is 110 linear metres. To avoid excessive temperature and pressure drops, recommends a maximum circuit length of 110 m (for the 15, 16, 18 and 20 mm pipe).
Pros and cons of underfloor heating
Is it the right choice for your home? This pros and cons will tell you everything you need to know about underfloor heating.
The pros of underfloor heating are as follows:
Lower running costs than electric or radiators systems, so better for large areas.
Does a better job at heating entire rooms rather than just the areas around radiators.
Frees up space in rooms, since no need for radiators
Could potentially add value to your property.
No maintenance regular servicing is needed.
Very user-friendly and is paired with a smart thermostat to control the room temperature.
Can be installed with various floor coverings.
Safe to use and is tucked away neatly from any contact.
The cons of underfloor heating are as follows:
Higher installation costs than radiators.
Takes a lot of time to install.
Slower to warm up than electric systems.
Can be difficult to install in older properties.
Can create hot spots on the floor.
