Discussion on radiators and heating

VKS radiators are made with an integrated valve set and a centre bottom connection – the connection is in the middle of the radiator. Is it possible to have the thermostatic head on the left-hand side of the radiator? Thank you.

Good afternoon, I would like to ask you for a quotation for Korada radiators 600 x 600 ..........................1 pc 600 x 800 ...........................1 pc 600 x 1000...........................1 pc 600 x 1200............................1 pc Thermostatic radiator valves ? ´´...............................3 pcs Shut-off valves ?´´....................................4 pcs I would also like to ask for a quotation for delivery to the address Nová Doba 485/1 , Nižná 02743 Thank you

Good afternoon, I am deciding which technology to use for the heating pipework (radiator heating) and for drinking water. So far I am leaning towards Pex-Al-Pex, but I still have a few doubts, so I would appreciate some advice: 1. I read somewhere on the internet (I am not sure, possibly on your website too) that screw fittings are not suitable for casting in concrete or plastering into walls. What is the truth? Is there a problem with the quality of the joint, and if so, what kind? That press joints should be used for these purposes (I am planning to do the heating myself). 2. If screw fittings can also be used in a concrete screed (or under plaster), can these Pex-Al-Pex pipes and fittings (insulated with some kind of pipe insulation, e.g. Mirelon) be laid directly on the bitumen sheets that are torched onto the foundation slab (that is, in a cut-out in the 4–5 cm floor polystyrene – so the insulation under the screed will be the floor polystyrene mentioned, but a groove would be cut into the polystyrene where the pipes run)? Or does contact between the concrete and the Pex-Al-Pex pipe and fittings need to be prevented by some kind of cover (so that the groove in the polystyrene for the pipe is covered with something)? Thank you very much for your answers.

1. No joint of any kind should really be cast in concrete, simply because if it starts to leak you have to chisel out an opening. But if there is no other way, they can be walled in as normal; it is just better to wrap them in a bag so that the concrete does not run into them. Whether screw or press fittings, it makes no difference here, except that press fittings are quicker to make. 2. Pipes should always be insulated, and they can be laid quite normally on the foundation slab, on polystyrene or in a groove. Nobody ever makes an issue of this. The pipe can be cast in concrete without any problems, insulation included. After all, that is how all underfloor heating is done. You will find pipes and insulation here https://www.atria.sk/potrubie-pre-vodu-vykurovanie/

Thank you very much for the extremely quick reply. So my conclusion is: whether for heating or for water, always fit a cabinet with a manifold.

Well, that need not always be the case. A heating manifold is used as a kind of large splitter for the pipes, so that you do not have to connect the radiators through a tee. With underfloor heating it is clear – there a manifold is essential for balancing. For water it is not used much, because there are not always many draw-off points, so it is done with a tee or with pass-through wall plates.

Which type of radiator, by output, is suitable for rooms with a heated volume of 52m3, 36,4m3, 62,4m3? Thank you

Good afternoon. Above all, a great deal depends on the heat losses of the house. As a general rule, though, you allow 1 kW of heat output per 10 square metres. The output is shown for each radiator; the most common height is 600. https://www.atria.sk/radiatory/

Good afternoon. What is the difference if, for two-circuit heating, i.e. radiators/underfloor heating, I use a standard condensing boiler or a two-circuit boiler? What is its advantage, given that an ordinary boiler is commonly used for two circuits as well? THANK YOU

Good afternoon, a two-circuit boiler gives you roughly 45 degrees for the underfloor heating and roughly 65 for the radiators. Only Geminox offers one like that https://www.atria.sk/kondenzacne-kotly/moznost-pripojenia-zasobnika/geminox/pre-dva-vykurovacie-okruhy/, if you do not have a two-circuit boiler, it is solved with a manifold that separates the temperatures https://www.atria.sk/mosadzne-rozdelovace/rozdelovace-podlahove-kurenie/ivar-rozdelovace-s-cerpadlom/ . If you are installing new heating, have the radiators designed for a flow temperature of roughly 45–50 degrees and you will heat both the underfloor heating and the radiators at a single temperature.

are Stelard radiators suitable for hot water systems heated by condensing boilers? Thank you in advance for your answer and I wish you a pleasant day.

Good afternoon, all radiators are suitable for condensing boilers too. They just need to be slightly oversized, as a condensing boiler heats at a lower temperature. That means they need to be specified a little larger.

Good afternoon, I would like to ask your opinion on choosing a radiator type, KORAD vs KORADO. Which would you recommend? Thank you

Good afternoon, all radiators are much of a muchness. What matters most is the price and the delivery time.

Good afternoon! Do you also stock KORADO radiators, please??? Thank you

Good afternoon, we do not stock Korado. The brand we sell is DELTA. https://www.atria.sk/radiatory/
