The hot water generator by the Nova energie is cost-effective way to generate hot water instantly. Hot water generator is designed exclusively requirement for hostels, hospital, resorts, swimming pools, dairies, laundries and various other process industries. Hot water generator can be pressurized and non-pressurized depending upon the required temperature of water. If the required water temperature is below 100c, then the hot water generator need not to be pressurized as the boiling point of water at atmospheric pressure is 100 c then the hot water generator must be pressurized and its pressure depend upon the required outlet temperature along with factor of safety.
