We live off-grid and collect/store rainwater (under our house) which is pumped (via 1/2HP pump) to a pressure tank and then to our Paloma PH-24M-DP propane fired (indoor) water heater. This setup has not changed in 20+ years.
However, a couple days ago the heater started acting strangely. Normally, after we light the pilot & turn the dial to the ON position, the main burner does not fire until after we turn on a hot water faucet. For some reason, the main burner is now igniting as soon as I begin turning the dial from Pilot to ON even though there is no request for hot water. If I do nothing (i.e., do not turn on a hot water tap), the heater will just heat the water to almost boiling temps.
Any idea why this is happening?
