Hello, very interesting video. I have a goulds resiboost vfd pump also so according to this video i can also hook a 20 gal pressure tank and it would save on energy consumption? I'm wondering if that's the case then would it not have been better to use a standard Gould pump with pressure tank instead of a vfd pump without a pressure tank.Which set up in that case do you think would use less energy?
Hi, you gain the most if you have a VSD pump that you can set the turn on and turn off point with a tank. Something like the hms1500 works really well for this. If you can set for example a target pressure of 4.5bar and a turn on pressure of 2bar it would benefit from a tank. Not all pumps can be set like this though, for example the DAB Esybox doesn't allow you to set more than a 1bar pressure difference this a tank doesn't make sense with it.
It is difficult to say as it will depend on the pressure switch. A good place to start though would be 1.4bar as many of the pressure switch are set around there.
If you have an in line 3 stage filter with ph correction vessel, extra siliphos cartridge and UV filter, where would the best place be to install the pressure vessel. Would a jet pump without controller be sufficient?
It depends a bit on what is practical in your setup. Ideally I would say just after the system as then you have a buffer of treated water, but you might find that this will let the pump cycle a bit more. On the jet pump you will need a controller to turn it on and off depending on pressure. What do you have at the moment?
@@FilterShopZa thank you for the explanation. I also initially thought to install it after the treated water. I have a 0.75kw jet pump with basic controller. Not the most user adjustable, but does the job.
Try if as it is but if you find your not getting much capacity out of the tank you can upgrade to one of these adjustable controllers: filtershop.co.za/en/coelbo-switchmatic-1@@renierjoubert9176
