APOLLO DHW120 MAX - Stainless Combined Indirect Water Heater Tank

$2,799.00

The Apollo DHW120 is a space-saving combined tank that integrates both the DHW (Domestic Hot Water) and Buffer Tank into a single unit. Designed for exceptional durability and efficiency, this unit is ideal for residential or commercial applications. The Apollo DHW120 is engineered to deliver reliable performance and is compatible with a Hydro Smart system or, alternatively, a plate heat exchanger (PHE) for optimal functionality.

The buffer tank is a critical component for the proper operation of a hydronic heat pump system. During very low or no-load conditions, the buffer tank provides the necessary time for the heat pump to react and shut down correctly, preventing temperature spikes. In winter, it also aids in the defrost cycle.

The DHW Tank functions as an indirect Domestic Water Heater, utilizing a boiler or heat pump to heat the water. The tank is designed without an inner coil, ensuring compatibility with external heat exchange systems such as a Hydro Smart system or a plate heat exchanger.

Key features include:

  • Buffer Volume: 25 gallons (prefilled with 24 gallons of glycol)
  • DHW Volume: 95 gallons
  • Inner Tank Material: Stainless Steel 316, 1/16" thickness
  • Outer Jacket Material: Painted Galvanized Steel, 1/32" thickness
  • Insulation: 2" thickness
  • Connections: NPT female
  • Drain Valve: Included
  • Pressure Relief: 125 psi, 210°F (CSA/UL certified)

The high-quality insulation minimizes condensation and heat loss, while the stainless steel construction ensures long-lasting corrosion resistance. The Apollo DHW120 is a versatile and efficient solution for modern heating systems.

This model no longer includes an internal coil. It must be paired with a Hydro Smart system or alternatively with a plate heat exchanger.

Ideal for Vacation Rental

As a vacation rental owner, I'm always looking for ways to improve guest experience while keeping costs down. The Apollo DHW110 Max has been a fantastic addition to our property. Guests love the endless hot water, especially large groups. The energy efficiency has significantly reduced our utility costs, improving our bottom line. The quiet operation means no complaints about noise, even from light sleepers. The durable construction gives me peace of mind about longevity. It's been a worthwhile investment that has already paid off in positive reviews and repeat bookings.

Great for Business Use

We installed the Apollo DHW110 Max in our small gym, and it's been a fantastic addition. The large capacity ensures our members always have hot water for showers, even during peak hours. Energy efficiency has helped keep our operating costs down, which is crucial for a small business. The quiet operation is a plus - members don't even notice it's there. Durability seems good so far, handling constant use without issues. The initial investment was significant, but the long-term savings and improved member satisfaction make it worthwhile. Highly recommend for small businesses with high hot water demands.
