We have a 70kw HP water heater with a HE to separate the pool water. therefore in order to maintain 28c in the pool the primary needs to be around 40c. HP's are more efficient at lower temps and the client is looking to replace the unit. We recommend a proper pool heater. However my guy reckons a 70kw c/w HE has a different rating to a direct inline Swimming pool HP
He seems to think we'd need to up rate it to an 80+ kw to give equal performance ?
. That seems at odds to what I would naturally consider right especially as a HP unit de-rates the higher the discharge temp goes and a HE takes another chunk of efficiency so my hunch is that a direct 70kw HP should give better performance like for like?
Thoughts inc real world examples welcome :-)
