I've mentioned this in another thread, but would like to attract more attention and get opinions.
My pool installation is pretty old, so There's a 20 amp line running from the house to the shed, with two switches (one in the house and one in the shed), powering my 3/4 HP pump (11 amp). I am putting in a Hayward H250FDN heater tomorrow, which has electronic ignition and needs a little power to operate.
I'm planning to have the pump and the heater connected in series, and have an extra cut-off switch for the heater. This way if I ever forget the heater running and I switch off the power from the house, the heater will also completely shut down together with the pump.
PS. It is not cost effective to install a second power circuit for the heater.
Do you anticipate problems?
Thanks in advance!
