divnkd, it's really none of my business and it may be too late, but, if I were you, I'd blow off that 3 hp pump and see if you could put that upgrade toward a 400 mmbtu/h heater.

Eljefe, I must tell you that was one of the easiest decisions we made. I have no plans of heating my pool. Even though it is piped so I can heat it, I will never take that step. My heater is for the spa. I don't deny the fact that the 400K BTU heater would heat the spa slightly quicker, but I am willing to wait the extra 5-7 minutes. That is why I spent the extra money on the wireless controller. With a push of a button, I can turn on the spa, set the desired temperature of the water and watch the remote until that temperature is reached. Furthermore, I would have to dish out an extra $500 bucks to swap the gas meter and have the inspection done before upgrading to a larger heater. Keep the opinions coming. I enjoy learning what everyone else's thoughts are. Thank you.
