Yes, I thought the hot water tank was getting hotter, but I realize not. The hot water tank says that the maximum is 70ºC and I always have it in less than half, so it must be less than 50ºC, anyway I can measure it with a tester that I have with thermocouple. I'm going to measure it tonight to see how much it goes out and if it's less than 50ºC, I put it on the exit directly!
Hi Leon, thanks for the reply.
Look, I don't know who did the installation, I'm there recently. I really don't know what to put. My idea, not to harm the hot water tank (although it says it is suitable for pressure pumps) is to put the pump in the outlet. Putting the pump in the outlet is relatively easy (connect it, at least) and I could do that. The low hot water pressure seems to me to be because the hot water tank is at the same level. That is, in the bathrooms on the top floor (where the hot water tank is) there is less pressure in the hot water. Cold water comes out well.
According to lei, there should be 2 meters between the water outlet (shower) and the tank floor. This I think is not fulfilled and hence the low pressure should be. What I do not understand is that if the water heater does not reduce the pressure, why does the cold water come out well? I don't know whether to put the pump from the tank manifold or put it directly into the hot water outlet of the hot water tank. I understand that the Rowa pump works with a maximum of 50ºC, and I don't think there is a problem because the hot water tank is always below half in temperature. What do you recommend me?
Do you want to know how much is 14 mca? That pump lifts 14 meters, water column, a barbarity, you need a maximum of 2 mca - most likely you have a blockage somewhere in the hot water pipe - did you check the connections of entrance and exit to the thermos ?? - out there, they put wrong a couple of turns of teflon covering ,, the holes and it complicates everything-- in the case of not being so- I insist ,, it counts the costs-it can be cheaper, lift the tank
Thank you for all the help, just leave an accepted solution, but would have accepted the 2. Thank you very much for the collaborations.
