Eelnev jutt on puukuuri kütmisel paika pidav, A energia majas on pealevoolu ja tagasivoolu temp. vahe max 5*C (õues 0 majas 21 radikasse 31 radikast 29)EMS kirjutas:Ei saa päris nii üks-ühele selle teksti järgi toimida. Kui mul praegu radikasse tulev temperatuur on 30 C ja toas hoian 22 C, siis ei ole kuidagi võimalik, et temperatuur radiaatoris langeb 12 C.

Re: Alpha 2
Vana asi küll aga sügiseti on ikka keegi mingi probleemi ees.Aga antud majal on ikkagi ülemine T-kujuline jaotus ja kui on mitu erinevat püstikut siis peab paratamatult need seadistama ainuüksi radika termod seda ei tee.Muidugi iga maja on omaette üksus ja igal (vanal) majal on oma head ja vead.Ja veel parem ,et on ka kaasamõtlejaid olgu see kas või vale.

Re: Alpha 2
Panen siia Grundossi radikate tasakaalustamise õpetuse, mis on veidi parem sellest, mille kunagi postitasin.
P.S. Ega keegi ei tea, mis võib põhjus olla, et ALPHA 2 Auto Adapt võimsus näitab pidevalt 18w (10 radikat, 160 m2, väljas +3 C). Kui panna proportsionaalse (II) peale, siis näitab 9-10 w ja on ka maja soe. (Tarbevee boileri kütmise pump on ka jadamisi ja I astme peal - 5w)?
System radiator balancing It is not possible to give specific information regarding the speed setting for the pump, as the required pump performance depends on the resistance of the system to flow. Larger systems will generally require a higher pump speed setting than for smaller systems. However, following the method below will allow the system to be balanced. Set the speed selector switch to speed II initially. If a bypass valve is fitted, set the bypass valve to give satisfactory operation of the boiler under minimum heat load conditions. The bypass will need to be re-adjusted if the pump speed setting is changed. Set all thermostatic radiators valves to full open, or remove the valve heads, ensure that the valve pin is free and not holding the valve closed. Initially set the lock shield valves, for radiators close to the pump set the valve to ¼ of a turn open, and those more remote to ½ to 1 turn open. Allow the system to stabilise, then check the temperatures of the flow and return pipes of each radiator. The temperature difference should be between 10°C and 20°C depending on the boiler operating requirements, for example flow temperature 70°C with and return temperature of 50°C to 60°C. For balancing the system, it is suggested to use a flow temperature of 60°C to 65°C, as this temperature can be just about be felt by hand without burning. A return temperature of 40°C to 55°C can be felt comfortably by hand. If the differential temperature is too low, slightly open the lock shield valve; and if the differential temperature is too high close the lock shield valve slightly. Work around the system several times until system balance has been achieved. When the system is finally balanced, it may be that lock shield valves on radiators close to the pump are only 1/16th or 1/8th of a turn open, this is perfectly acceptable as long as there is a good temperature difference across the radiator. Radiators further from the pump may have the lock shield valve set to full open. The regulation of the lock shield valve has the most effect in the first half a turn. If the system can not be balanced using speed II, and there are radiators where the temperature differential is too great, then the pump speed setting should be increased to speed setting III. If the system can be balanced, but the lock shield valves are generally 1/8th to ¼ of a turn open, then it may be possible to re-balance the system using speed setting I, and opening the lock shield valves. A high a temperature differential across the boiler indicates insufficient flow. Correct this by either increasing the pump speed setting and or opening radiator lock shield valves while maintaining the system balance. Operating the circulator on a high speed setting or operating with a low temperature differential, leads to
unnecessarily high power consumption. A high speed setting may also lead to noise in the system and
radiator valves. For systems with condensing boilers, it is important to operate the boiler with a return temperature of 55°C for the most part, in order for the boiler to be in condensing mode to achieve a good efficiency
