Radiator with 2.7 m length

Good day,

I want to replace the radiators in my apartment, one of which currently installed has a length of 2.72 m, the distance between the heating pipes is 2.84 m. A new radiator has a standard size of 0.6 x 2.6 m. That means I would have to compensate the longer distance between the individual heating pipes (supply and return) and the connections to the radiator of about 12 cm with connecting pipes, which does not necessarily look nice. I thought about connecting 3 radiators with a length of 0.9 m each in series, thereby achieving the suitable length of 2.7 m. Would it be sensible and even feasible to install 3 radiators one after another? Thank you for your answers.

Can be done. Sensible? Well, you have various problems to solve.
- Connection scheme (simply one after the other doesn't work, as the first radiator receives warm water, but the second then already cooled, and so on). Perhaps a Tichelmann piping?
- Hydraulic balancing
- Number of thermostat valves - rather only one on the last or first (but the connection scheme and possibly new piping must be considered).
- Venting in series

I think proper connections on the 260 are even better looking than three radiators in a row.

Three radiators in series is not a problem, if I interpret it correctly the radiators will then be connected alternately just like the old radiator. But there is another catch, you forgot to include the dimension for the coupling pieces ([Dg, Verschraubungen um die Hk zu verbinden]) in the total length measurement. I would compensate the 12cm with two valve extensions of 6cm each on both sides. You can use chrome-plated ones, paint them white or ... or.

But then the second one already gets cooler water and the third has to take whatever is left.

But that has to do with physics and less with the number of radiators.

The heat output per se is always the same overall - just in a different place, distributed over the surface.

And that would be what would bother ME... aside from the fact that in my eyes it would look extremely ridiculous...

The three radiators are flowed through exactly as if it were only one. The reciprocal connection already ensures this. Supply to the first radiator. Return at the last radiator. If the piping network had been calculated and executed, it would also work without this cross connection.
