Stiebel Eltron Accelera 300 E Heat Pump Water Heater, 240V, 80 gallon, 233059

Stiebel Eltron Accelera 300 E Heat Pump Water Heater, 240V, 80 gallon, 233059, 040232177026

Heaters are designed from the ground up to rely on the heat pump, not on the support-up element becautilize that is the most efficient way. Our “50-gallon” heat pump water heater is actually 58 gallons and our 80-gallon model is, well, 80 gallons, becautilize large is the best for a heat pump water heater. Large capacity means the water you are using, as much as possible, was heated the most efficient way – with the heat pump.

We super-insulate our tanks, becautilize minimizing stand-by losses means less energy is wasted. For maximum energy savings it creates no sense to skimp on the insulation and boost energy consumption. We utilize a single resistance element for support-up water heating during times of high demand. Our single increaseer element is located in the most efficient place – at the very top of the tank becautilize that’s where the hot water is drawn from.

Until recently, the best “high efficiency” water heaters could only approach 100% efficiency. Heat pump water heater technology redefines water heater efficiency, producing efficiencies more than 3 times that. For every watt an Accelera’s compressor and fan utilizes, the equivalent of 3-5 watts of hot water are generated.

In warm climates, an Accelera is placed either in the garage, where it utilizes the heat from the outside air to create hot water, or inside the houtilize, where it assists with the air situationing load. In cooler climates, the unit is typically placed in the basement where it also acts as a dehumidifier. You get hot water at a discount plus a drier basement as well.

Here are some of the features of our heat pump water heaters and why they have them:
Digital display
SG Ready

The Accelera 220 E and 300 E have a easy-to-operate end utilizer menu that is accessed through the electronic display. The display also demonstrates performance information, including total volume of Homehot water available. Accelera is “smart meter” ready and choices are accessed through the display.

Easy access for service
The entire top of an Accelera 220 E and 300 E can be rapidly removed for simple servicing from all sides.

Redesigned air flow
Air intake and exhaust are angled to allow opportunity for installation in compact spaces. In addition we decreased noise by separating the airflow from the refrigerant loop and increasing fan diameter.

Impressed current anode corrosion protection
The Accelera 220 E and 300 E are equipped with an electronic anode for maintenance-free protection instead of an anode rod. This system also provides protection with the minimum current necessary as opposed to a steady-on system.

The condenser
Accelera Roll-bond condenser

The evaporator
Accelera’s efficient evaporator has superior cold climate performance

The cold water inlet
Even the smallest thing is not overlooked. The cold water inlet is designed to prevent incoming cold water from cooling the hot water in the tank during a draw. This assists provide the greatest possible volume of hot water without using the increaseer heating element. This feature also boosts heat pump efficiency by allowing a small cold water reservoir to remain in the very bottom of the tank.

The Accelera 220 E and 300 E have a roll-bond wrap-around condenser becautilize it prevents refrigerant contamination of the water, mitigates hard water issues (in conjunction with the glass-lined tank), and is the best answer for energy efficiency.

The coating on the Accelera evaporator protects against corrosion and also allows quick water drainage for boostd air flow and greater heat transfer and efficiency. Becautilize the evaporator is self-cleaning no filter is required. A dual-path refrigerant flow provides cold climate performance in addition to warm climate performance.

A heat pump water heater’s recovery time is slower than a standard tank. But with the correct balance engineered between tank size and heat pump capacity, both efficiency and comfort are possible. The tank in an Accelera 300 E is 80 gallons becautilize we understand that is an optimal size to satisfy average annual houtilizehold hot water demand as much as possible via the heat pump. Similarly the Accelera 220 E tank is 58 gallons becautilize it is an optimal size for smaller houtilizeholds. With both models, if more hot water is needed, the single support-up element at the top of the tank near the outlet ensures comfort without sacrificing efficiency.

How a heat pump works in an Accelera?
An Accelera works like an air situationer, but instead of transferring the heat to the outdoors, it transfers heat into the tank of water. This process is many times more efficient than any other type of water heater.

It works like this:
The fan moves room air through the evaporator, which contains liquid refrigerant that extracts heat from the ambient air as it evaporates. As the refrigerant warms, it alters into a gas. The warm gaseous refrigerant passes through the compressor which boosts its pressure. As the pressure boosts, the temperature of the refrigerant rises until it becomes hot. The hot refrigerant then passes through the condenser wrapped around the water tank. Becautilize heat travels from hot to cold, the heat in the refrigerant transfers to the water in the tank. The refrigerant, having transferred its heat to the water is now a super-cool liquid. It then passes through the expansion valve to become a warmer, yet still cold, liquid, ready to become a gas again in the evaporator and continue the cycle.
