Re: How to increase pool heater capacity?
With regard to the installation the unit is raised about a meter off the ground . I need to check whether the water fills from the top or the bottom. Ideally we should be filling from the bottom with contra flow refrigerant. If it filled from the top or some how has an air pocket in the heat exchanger i could get the high hp with poor temp difference.
Once again if I do the KW = l/s x 4.19 x temp diff
This will tell me what the unit is delivering. We can compare this to the compressor capacity curves and then confirm whether it is working to the specs. if not find the fault. if it is then the suppliers need to pass over a true 30 kw as spec,
