An illustrated view of an exemplary pool heater device for providing heating of water for a swimming pool is presented. The pool heater device is useful for providing a quick and almost instantaneous heating of the water for a swimming pool. The pool heater device further has a quick and easy installation and can be installed on any swimming pool of any size. The pool heater device is portable and can be installed by an owner of the swimming pool without help of others.

A portable water heater assembly for heating water being dispensed into a drinking glass includes a base that has a fluid reservoir integrated within the base to contain a fluid and a fill port integrated into the base. A bottle is provided to contain water and the bottle is insertable into the fill port to direct the water into the fluid reservoir. A faucet is integrated into the base to dispense the water from the fluid reservoir. A heating element is integrated into the faucet and the heating element is in thermal communication with the faucet. The heating element heats the faucet when the heating element is turned on thereby heating the water when the water flows through the faucet.

A manually controlled and operable self-propelled seed bed sterilization system and method is provided for preventing weeds from growth in seed beds. The system includes a wheel driven shuttle vehicle having a hot water reservoir, a hot water applicator manifold housing, a dual-function pump and a controllable valve. A self-contained mobile hot water supply vehicle accompanies the shuttle vehicle and has a water heater with hose connections to the reservoir of the shuttle vehicle to provide a continuous water flow path. The burner of the water heater is controlled to heat the water in the range of about 205-207 degrees F. but below the boiling point of water not to create steam. The shuttle vehicle is displaced over the seed bed at a constant drive speed by an electric motor driven by a gas generator. An operator person guides the shuttle vehicle over the seed bed.

The notched base ring comprises a base ring sheet body including a top portion, a bottom portion, a first end connecting the top portion to the bottom portion, and a second end connecting the bottom portion to the top portion. The top portion includes a plurality of attachment lugs and defines a plurality of notches, each notch being at least partially defined by two lugs disposed on opposite sides of the notch, the top portion also including an angled top edge that is disposed at each of the attachment lugs, and the bottom portion includes a bottom support edge.

A method of controlling a gas powered water heater includes attempting to pick a main gas valve of the main burner using a first pick method. The first pick method includes closing a switch of a valve pick system to couple a capacitor of the valve pick system to the main gas valve for a first length of time to discharge energy stored in the capacitor to the main gas valve, and opening the switch of the valve pick system after the energy stored in the capacitor is discharged to the main gas valve. The controller determines if the main gas valve is open after using the first pick method. When the controller determines the main gas valve is not open, the controller attempts to pick the main gas valve using a second pick method different than the first pick method.
