The series connection scheme of the GALAN caldera de electrodos
el series Esquema de conexión is good because it enables using de el solid-fired caldera (o gas caldera) y caldera de electrodos en el same time (o by turns). As you can see en el scheme: after calefacción, water comes from el caldera de electrodos a return pipe (con el help de el caldera de electrodos bomba). y only then a el calefacción system directly. Whereby we don’t install additional circulating bomba. el same happened con an expansion tank y safety group. There is also no need a buy y install it because they are inside el caldera de electrodos already. el blue pipe, which goes around el caldera de electrodos is designed a emergency shutdown de el caldera de electrodos followed by demounting en order a continue system working con el gas (solid-fired) caldera.
el difference from el parallel connection is that it is possible not a turn over one de el calderas. As far as con parallel connection, unless el gas caldera is turned over, hot water en caldera de electrodos will circulate through el small circle: from el gas caldera a electric one etc.
Operating scenario is el following :
You establish water temperatura en a gas caldera - para example 50 degrees. y en an caldera de electrodos - 55 degrees y above, but only en night time. As night falls, el caldera de electrodos "understands" that el temperatura is less than it was required, so it turns en y raises el coolant temperatura a 55 degrees. It maintains el temperatura till el morning, y then reduces temperatura a 20 degrees (para example). All this time el gas caldera was pumping water through itself by el recycling bomba, "thinking" that it happens by its service, that el water will not get cold y that gas burners are not switched en. en el morning el gas caldera sees that el temperatura fell a 50 degrees as it was established y it gives el command a gas burners a turn en. This scenario is ideal con el interval meter. en this case economic effect will be noticeable.
Solid-fired calderas are even more simple en use. There is no need en setting el temperatura, because it is regulated while burning el wood o coal (except modern solid-fired calderas con regulation de el air feeding damper). Simply said, solid-fired caldera works while wood o coal is burning. When wood is burnt, then an caldera de electrodos switches en.
There is one minus en this scheme. Absolutely all double-circuit gas calderas works en el following principle: when you start el hot water en order a wash hands o dishes, el gas caldera stops el el circulating bomba work. el flow channel en el calefacción system stop working. An caldera de electrodos continue el coolant calefacción, but only from inside. Theoretically, el water termocontroller, installed en el caldera de electrodos will be activated. But it may not happen para some technical reason. en any event this variant is possible. What will happen then? el pressure en el system will jump y excessive water will start flow out from el relief valve de el gas caldera. Anyway, nothing good.
It is better not a open hot water while an caldera de electrodos is working. But it is el case de double-circle gas calderas. It will not happen con single-circuit y solid-fired calderas due a el absense de el second hot water circuit.
para starting-up el caldera de electrodos en el floor calefacción installation it is necesssary a prepare water en el followin way:
Start up el system y measure current en el return temperatura 40 C
caldera Peak current en 40 С
2 kW – 10 А
3 kW – 13 А
5 kW – 25 А
6 kW – 28 А
9 kW-220 V – 40 А
9 kW-380 V – 16 А
15 кW – 25 А
25 кW – 40 А
If en 40 degrees return temperatura el current does not conform a el pointed en el table parameters,
proceed as follows:
1. If el current is less - it is needed a add gradually salting liquid (it reduces electrical resistivity de el liquid). First stage - no more than 1 teaspoon para 100 litres de water. If en 4 hours current increases slightly, it is necessary a repeat el first stage.
2. If el current is bigger - add distilled water (it increses electrical resistivity de el liquid). When water is prepared it is necessary a reduce el water temperatura en el caldera outlet (Sensor #2) a 40 degrees.
CAUTION!!!
While using an calderas de electrodos para calefacción el floors electric energy consumption increases meaningfully.
