All Solahart water heaters are fitted with a gas or electric in-tank booster, which operates only when you need it. Or you can choose to have an in-line booster, where the hot water from your tank is piped to the booster which senses the temperature and activates if it is less than the set temperature. The in-line booster has a 5 star energy rating, keeping your energy consumption as low as possible.
That means you can enjoy hot water when you want it, even on overcast days or at night.
