My house has 2 water heaters. One for gas and one for the solar. Looking at the piping, I think the water is comming to the solar heater first, then through the gas heater to inside the house. Both are turned off now.
The solar also supplies water heat for the swimming pool, which is removed now. They cut off the pipes right at the pool. I will plugged the pipes up soon before I turn the water heaters on.
I am not sure if I should mess with the heaters to turn them on or do I need the pro? Anyone know who should I call? The solar company, or the gas company, or both?
Thanks.
