Our Custom units come in two varieties:

1. Geyser C-Series: a commercial size heat pump water heater that can be tailored to your needs

2. Geyser Solutions: Typically these are for large commercial and insdustrial applications. We can design a heat pump solution customized to your needs including:
• Water to water
• Use patented design to reach high temps up to 215ºF (102ºC)
• Cold climate ambient temperatures down to -20ºF (-29ºC)
• Large capacity systems

Geyser C-Series: Tailored to meet your needs

Our C-Series is a high efficiency air-to-water heat pump water heater that can be tailored to your needs in several ways. They range in capacity from 25,000 BTUH to 250,000 BTUH, generating from 50 to 500 gallons of hot water per hour. Just take a look at the table below and specify your own.

How does the GEYSER® work?

Heat is extracted from the air surrounding the unit and utilizing heat pump technology, that energy is used to heat the water in your storage tank. As a by-product of heating water, they cool and dehumidify the air. This air can be ducted to where it reduces the load on air conditioning, further increasing your savings.

What applications are suitable?

These units can heat water efficiently up to 150°F (65°C) and are ideally suited for restaurants, hotels/motels, apartment buildings, laundry facilities, health care facilities, schools, sports arenas, gyms, institutions such as prisons, military barracks, specific manufacturing plants, and more.

The C-series has a base configuration and can be tailored to your needs with a range of options and accessories.


Options and Accessories

Defrost Cycle: The basic model comes with a defrost capability to allow it to function in ambient temps down to 20°F. If yours is an (indoor) application where the ambient temperature will not drop below 45°F you can eliminate this feature for a discount.

Corrosion Resistance Package: The basic model comes with a painted aluminum cabinet to provide superior protection against corrosion.In addition, the corrosion resistant package adds coated coils for extra protection in highly corrosive environments like for example salty air close to the ocean.

Vented Heat Exchanger: The basic model comes with durable heat exchangers. The vented heat exchangers are optional for applications involving drinking water in the US and Canada.

Blower: The basic model comes with a propeller fan for maximum efficiency. If your application can take advantage of the cooled and dehumidified air, the propeller fan can be replaced with a blower than can be ducted to where the cooled air can be used.

Circulator Pump: The base model comes with an external water circulator pump sized to proved the required flow rate with 5 feet of head (external to the heat pump). A larger pump can be provided when the total head feet is more.
Power requirements: The basic models come with the following power requirements: C25, C40 & C60: 240/1/60 — C125 & C250: 240/3/60 — Other power requirements are optional.

Air to Water: The basic model is configured as an air to water unit. Alternatively they can be configured as a water to water unit to extract its heating energy from a water source, for example to cool water for the A/C or off-load small cooling towers.

Base model features and benefits

• The commercial units heat water efficiently up to 150F.
• Typical operating at COP from 3.0 to 5.0, meaning it is expected to save 60% –
75% versus the costs of running an electric water heater.
• The air surrounding the units is being cooled and dehumidified, reducing the need
for air-conditioning and further increasing savings.
• Can be connected to most storage tank water heaters, including: Electric, Oil,
Natural Gas, Propane.
• Can be disconnected and reinstalled with other tanks in case you change tanks.
• Minimum ambient temperature to run is 20°F. If the temperature can go lower,
having a back-up heat source for just those occasions is recommended (can be the
heating element in the existing tank).
• Drinking water lines implies that if they are exposed to sub-zero temperatures heat • strips should be added (the water in the pipes and heat exchanger can freeze-up).
• Uses environmentally friendly R-134a refrigerant and an energy efficient scroll
• Quality temperature controller with tank probe is included.
• Comes with one year limited warranty.
