Therma-Flow provides the ideal solution to supplying ever ready, ever hot and an always plentiful supply of domestic hot water for your home or business. Each Therma-Flow AquaPlus tank with its specially designed mega coil heats water by capturing the energy created by your existing boiler. It's called an"indirect water heater," because it's linked to your boiler and stores hot water at the desired temperature. The AquaPlus tank is thermally wrapped so it easily maintains hot water temperature and, because the AquaPlus is glasslined, it offers exceptional long term performance. It's durable and the Mega Coil assures you of a reliable way to meet your most demanding hot water requirements. AquaPlus tanks are designed to serve a wide range of hot water applications and provide superior performance with all kinds of hydronic, radiant heat and steam heating systems. Households with multiple appliances and bathrooms, whirlpools, and hot tubs, benefit from an ample supply of hot water without concern of runouts.

• Glass-lined heat exchanger within a glass-lined tank
• Over sized mega coil guarantees superior heat transfer
• Stylish outer jacket

Crown Boiler Mega-Stor is the first indirect water heater to have its performance independently certified to specifications by the hydronics institute. This independent testing will assure you of accurate ratings. Mega-Stor is indirectly heated for efficiency. The boiler that heats your home or building provides more energy, while consuming fuel more efficiently, than direct-fired domestic water heaters. So Mega-Stor saves on fuel costs by using hot water from your boiler to heat water for your showers.

• The Mega-Stor is a stainless-steel indirect water heater which provides abundant domestic hot water utilizing energy provided by your boiler
• With a stainless steel, smooth surface coil that transfers heat throughout the tank, the Mega-Stor is capable of recovery rates well in excess of a typical gas, electric or oil water heater
• The 2" thick layer of polystyrene foam insulation keeps the water in your Mega-Stor hot for hours during stand-by periods
