Water Heaters (Calefones)
What suits me in my installation of water, hot water tank or water hea

Good morning and first of all thank you very much to everyone who responds.
I am doing a water installation in my apartment from a Sisterna tank. I bought a 1000lts Sisterna tank, a 1hp pedrollo pump (I think I went too far to "introduce a bad word here") and a 24lts hydropneumatic tank. To feed a network made with hot melt pipes. Buy a shower panel for the bathroom (of those that have jets for hydromassage)
The problem is that I don't know whether to put a water heater or a hot water tank, which will work to keep the water warm.
According to the pump pulls 6000lts / h bone 100lts / min, the heaters as I understand heat 14lts / min
The mandamas (my mom) wants to put a 50lts electric hot water tank because it is "nice with the decoration" but I think she will not have enough time to heat the water that passes through it.
Any recommendation? Regards
attached the technical sheet of the pump in case the model is cpm 158

Excuse me, what is the pump for? A pressurizer? Doesn't the tank have adequate height?

I think you bought a pump too big, with 1 bar left over, is it a centrifugal pump ?, because I don't know pedrollo pressurizers.

Yes, it is a centrifugal pump, I did not want to buy peripheral because according to a friend, he had a peripheral of 1 / 2hp for a shower like mine and it burned after months, I know that the pump is too large, the one I bought was my mother and is harder than wolverine's claws, I am seeing that when I open the jets, I will pass by the wall. but some water heater or hot water tank will work for me ?.
it is assumed that the hydropneumatic tank acts as an "automatic control for pressure difference" the pressure switch of the hydropneumatic tank will cut when it reaches 2Kgf

I consider that as much as with a hot water tank as with a water heater, if you circulate so much water flow, you will not have time to heat enough water, the pump you bought is not pressurizing, the pressurizing pumps have a pressure sensor that activates them at the moment That you open a tap, yours not so I don't know how you are going to control it. I recommend you buy a pressurizing pump (or change it to yours), and connect it to the base of the tank, at the exit of the tank, that is, between the tank and the water heater, to avoid an excess of pressure you can regulate the pressure from the same pump or place a pressure valve, luck.

What pump would you recommend? Rowa brand pressurizers for tank tanks are expensive and they told me that putting a pump with a hydropneumatic tank is the same. The pressurizers of the rowa brand, the smallest that is supposed to be for a medium pressure bath is 1/2 hp and throws 66lts / min

The pump you bought costs the same as a pressurizer, try to change it, but the pressure of a small pressurizer is 3 bar and I think you can regulate it.

in advance thank you very much for fluid response. The pump I bought comes out half the price of the sisterna tank pressurizers I saw in the market. according to what I saw the smallest is 2 in maximum price. the one you buy, the maximum price is 6. the issue is that you already buy the hydropneumatic tank with the pressure switch and the pressure gauge to make it "automatic pump" and that will regulate it so that the pipe stays with a constant price, They told me that with 1Kg / cm2 is enough, can I find a centrifugal or peripheral pump that delivers those 2 or 3 bar ?.

on the other hand, I was looking at the specifications of the rowa pressurizer
Max. 19 (mca)
Max flow 4000 (l / h)
Power 0.5 (HP)
I 2.6 (A)
220v voltage
I saw an easy pedrollo centrifuge (where I bought the one I have) that has almost the same specifications regarding flow and power. But I do not understand the pressure, is that a characteristic independent of the power of the pump and the flow? I know it's "strength by area" but I'm honestly lost

I prefer the empirical rather than analyze specifications and so many calculations, you could buy a pressure regulator and place it at the pump outlet, with that you would avoid that the flow / pressure does not allow you to properly heat the water, the other is to treat to calibrate the automatic tank to work at the lowest pressure.

Put a hot water tank but a bigger touch, you will not throw 100lxmin in your yet.

Hello, thank you very much for your answer. But the pressure of that pump will not be able to break the jets? I still don't get the shower panel (I bought it online) but I calculate that they are plastic. Doesn't water pressure break them? although I calculate that if the pump pulls a lot of pressure it will cause the pressure switch to cut off the pump current when it reaches 2Kgf / cm2 in that case, if the pump arrives very quickly to fill the hydropneumatic tank it will not make it turn on and off very often ? Doesn't the bomb break? regards

It won't break anything. You will have pressure throughout the house. And if you want you can do a bath in the 3rd that will also arrive.

If I wanted to tell you that you have equipment to reach a 3rd. Floor. Do not worry.

Perfect! Thank you. With respect to the hydropneumatic tanker or hydrosphere, as they also tell you, will I have to regulate the high pressure switch cut to cut the type, 6 kg / cm2 so that the engine shuts down only when the tap is closed? Since it is the maximum pressure delivered by the pump and thus prevent the pump from turning on and off every time? Or am I getting confused with the issue of pressure?

With 2 kg / cm2 you will have enough pressure, say 1 kg is like 10 mtrs of translated water column ... your pump will start when necessary. Work less ...
