This may sound like a nutty query at the start of the summer. But we are considering getting a gas heater for our above ground pool. The sales rep for the gas cylinders be going over the options and one thing he mentioned be for the bigger heating units they are not comfortable beside the owners disconnecting and said we should winterize the heater instead of bringing it in. I search the topic and have not found anything on winterizing a pool heater. Does anyone know how this would be done? Also, is nearby a winterizing process for the pool pump/filter assemble that would allow it to remain in place as well. Every year we bring it surrounded by to the basement (no shed), but it is awkward and I fear injurious the plumbing connection from the pump to filter housing. If we could leave it adjectives in place that would be great, even if it means building some type of housing for it. Thanks.
