Central to Zwell’s purpose is our environmental mission. We believe that we can effectively combat the effects of climate change. We can start by reducing the greenhouse gas emissions of the homes we all live in.

Our journey in Zwell started with a love of entrepreneurship and a belief that the free market can solve many of the problems we face today. Collectively, we have several decades of experience building businesses, but we all were searching for more purpose in our work.

We started our research by looking at the UN’s list of global issues and from there, we were most drawn to the problem of climate change. Lightbulbs started going off. With the progress we are making with connected homes; it was pretty easy to imagine a not too distant future where smart homes would reduce the amount of wasted energy. Furthermore, with focused innovation and dedication we could picture a future where we could get to sustainable energy for all homes.

We partnered up with 1% for the Planet, B Corp, Spark Northwest, and Community Energy Project in achieving our mission. We also established a Zwell Community Fund

Error A108 means the heating source defaults to elements due to condensate drain blockage. The following steps can help you check the issue.

  1. Remove the top cover from the tank
  2. Visually inspect to ensure condensate line is clear and there is not excessive condensate in the condensate pan
  3. If water is present, locate the blockage and unlock it.
  4. Ask the customer where the condensate is being routed 
  5. If the pan is dry and no blockage is present, replace the condensate sensor.
  6. Also, this is often caused by a frozen condensate line during the winter.  So, depending on how the condensate line was installed and if it was uninsulated that could be a potential cause.  If you are able to test that water runs through the condensate line clearly then that could point to needing to replace a condensate sensor.

  • The power supply – make sure that there is power going to the water heater and proper wiring has been installed
  • The fuse and circuit breaker – make sure the fuse has not blown or the circuit breaker did not trip
  • The thermostat setting – make sure that the temperature was not set too low
  • Water usage may have exceeded the capacity of the water heater. Wait for the water heater to recover after huge demand. 
  • Leaking or open hot water faucets. Make sure all faucets are closed.

If the water that is coming out from your water heater is too hot, the thermostat is set too high. The temperature control must be double-checked to make sure that the temperature is within an acceptable level.

The water heater interface controls the temperature of the water in the heater. The Rheem water heaters are set at 120°F (49°C) by default before it leaves the factory.  This is to comply with safety regulations. 

Hearing a popping sound in the relief valve can be caused by increased pressure in a closed system. Fix this immediately.  Hearing a popping sound in the relief valve is an unacceptable situation.

If you purchased your water heater from us, please contact us so we can help. However, if you purchased your water heater elsewhere, contact your water supplier/utility, the plumbing contractor that installed the water heater for you, or the manufacturer of the water heater.

The buildup of scale or mineral deposits in the water heater may cause a rumbling noise. When this happens, allow a few quarts of water to run from the drain valve to remove the sediments.

If this doesn’t solve your problem and you purchased your water heater from us, please contact us so we can help. If you purchased your water heater elsewhere, try contacting the plumbing contractor that installed the water heater.  You can also contact the manufacturer of the water heater.

Rheem Professional Prestige ProTerra

The quick-release valve is a little lever on the top of a storage water heater.  It is for safely releasing excessive temperature and pressure inside the storage tank. Rheems’s water heaters have a built-in system to automatically monitor and control the temperature and pressure. However, for added safety, they also come with a relief valve.

Consequently, without the quick-release valve, the water heater may run the risk of an explosion. Most especially if the temperature or pressure got higher than what the tank was designed to handle.

To put it simply, storage water heaters can be dangerous or even lethal if they do not come with a temperature and pressure relief valve.

Zero clearance requirement is in reference to installation. This implies that when needed during installation, Rheem’s line of hybrid electric heat pump water heaters can be installed directly up against a wall. However, competing products require several inches of clearance. Meaning, there has to be a minimum distance between any wall and the water heater. Rheem designed their line of heat pump water heaters to have an outlet vent.

There are different operating options available for Rheem water heaters.  These are Energy Saver, High Demand, Heat Pump, Electric Only, and Vacation modes. The temperature and amount of power being used depend on what operating option the water heater is currently on.

  • Heat Pump Mode: This mode will heat with Heat Pump operation. It will not use electric heat during normal heating and demand cycles.  This mode has a low recovery but minimizes power consumption.
  • Energy Saver Mode: This mode will provide functional operation. Consequently, the water heater performance meets Energy Star’s requirements.  FHR (First Hour Rating) – exceeding the minimum of 51 GPH (Gallons Per Hour) and a minimum UEF (Uniform Energy Factor) of 2.0.  As a result, the use of electric heat is minimized while the compressor operation is maximized.
  • High Demand Mode: This mode provides the highest recovery while still providing good energy savings.  The water heater will operate both the heat pump and electric heat simultaneously.
  • Electric Only Mode: This mode will heat with the electric-resistance elements.  It should be used during filter and condensate drain maintenance periods.  This mode will result in maximum power consumption.
  • Vacation Mode: When you will be away from your home for an extended period of time, use vacation mode. This mode will allow a span setting between 1 and 28 days. It can also be set indefinitely with the “Hold” setting.  In this mode, the tank temperature will remain at 65°F (18°C). 

If you still have questions, contact us here!

If you leave for a vacation anywhere from 1 to 28 days you can set the water heater to vacation mode. The tank temperature will stay heated at around 65°F (18°C).  Furthermore, you can also set the water heater to hold. It will indefinitely hold the temperature you set it at while you are away.  

However, if you won’t be using your water heater for 6 months or more we recommend turning off the power and water supply. This is to conserve energy and prevent a build-up of dangerous hydrogen gas.

The water heater and piping should be drained if they might be subject to freezing temperatures while you are away.

After a long shut-down period of 6 months or more, the water heater’s operation and controls should be checked.  It is important to make sure that the water heater is completely filled again before returning to normal use.

Rheem’s ProTerra hybrid heat pump water heater is refrigerant is R134A. It is an environmentally friendly and non-chlorinated refrigerant. This refrigerant has zero ozone depletion potential. However, releasing refrigerant into the atmosphere may be considered illegal.

 

Rheem ProTerra hybrid heat pump water heaters have both an inlet duct and outlet duct.  The inlet duct pulls air into the condenser. The air then heats the water. Additionally, dehumidified air from the water heater is exhausted via the outlet duct. 

There are a few conditions where you’d consider ducting.

Inlet Ducting

An ideal location would be a room that has greater than 700 cu ft.  If the area of your water heater is smaller than 700 cubic feet and you don’t have the option of installing a louvered door then you may consider ducting air from outside the room using the inlet duct.

Outlet Ducting

If your water heater is located in a conditioned space like a laundry room you can expect cold dehumidified air to exhaust from the outlet duct.  It can reduce the temperature of the room by a few degrees.  Some homeowners choose to duct the cold air outside of a conditioned room.

Always check with local building and HVAC codes before designing the air duct system. Do not connect the water heater to existing ductwork; it must be ducted separately from other appliances. Ducting must be adequately supported along both vertical and horizontal lengths. UL Certified terminations must be used for ducting to the outside. 

For more information on how to properly duct a heat pump water heater contact us.

An ideal location for a hybrid heat pump water heater is in a clean dry space with enough room.  Also, the thermistor and element access panels should be accessible for servicing.  Keep in mind that installation in a confined space can lead to higher power consumption. Adequate ventilation should be provided.

CAUTION: The water heater should not be located in an area where leakage of the tank or connections will result in damage to the area adjacent to it or to lower floors.  Where such areas cannot be avoided, it is recommended that a suitable drain pan is used.

A water tank filled with water can weigh between 500 to 1,100 pounds. The weight depends on the tank size. Therefore, make sure the floor underneath the water heater location is strong enough to support the weight of the water heater.  Floor isolation kits are likewise recommended to minimize vibrations if needed.

Furthermore, ambient temperature should not exceed 145°F (63°C).  The water heater and water lines should not be installed outdoors in unprotected areas or where they would be susceptible to freezing temperatures.

The heat pump needs enough air exchange to operate efficiently and several locations will accommodate this.  Generally speaking, if the location of the water heater is in a room larger than 700 cubic feet (e.g. 7’ x 10’ x 10’) you will have enough air exchange for optimal operation.  If your location is smaller than 700 cubic feet you can use ducting or a louvered door to produce the proper air exchange.

For more information about the ideal location, you can contact us.

No, insulation blankets are not necessary for the Rheem Professional Prestige ProTerra model.

The CTA 2045 port adapter and UCM let your water heater to be notified of power grid conditions and to react intelligently. It works as a translator between your water heater and your electric utility’s control module. Because of this, it possible to engage in your utility’s energy management program. Furthermore, Rheem’s ProTerra is NEEA Tier 4 certified. It also comes with CTA 2045 adaptor with full Demand Response capability out of the box. The CTA Adaptor on the Rheem ProTerra hybrid heat pump water heaters allows for the installation of a CTA-2045 compliant module should your electric utility require it.

Apart from Rheem, other hot water heater makers are supporting the ANSI/CTA-2045 standard. This is for an open communications protocol and physical port for electricity-using appliances. Additionally, the protocol was developed by the Electric Power Research Institute, Consumer Technology Association, and others. It is a way for utilities to manage peak demand within their electrical grid.

Diagram Showing Tank Drain

Drain times vary for a variety of factors but a rough range is anywhere from 10 – 20 minutes depending on tank size.  If it is taking longer to drain the tank you can try to turn on the cold water supply to the tank to try and flush any impediments. The following steps will guide you on how to drain your water heater tank.

WARNING: Before manually operating the relief valve, make certain no one will be exposed to the hot water released by the valve.  The water emptied from the tank may be hot enough to present a scald hazard.  Hence, it should be directed to a suitable drain to prevent injury or damage.

  1. Shut off power to the water heater before draining the water.
  2. Turn off the cold water supply.
  3. Open a hot water faucet or lift the handle on the relief valve to admit air to the tank.
  4. Attach a garden hose to the drain valve on the water heater and direct the stream of water to a drain.
  5. Open the valve.

You can also watch the video below for reference on how to drain the water tank. Questions? Contact us here.

The automatic water shut-off valve has a self-check feature that runs every 30 days once the water heater is powered on.  This feature works by closing and reopening the automatic water shut-off valve.  In case the valve fails to reopen, the water heater is disabled.  The water heater gives an alert when the automatic water shut-off valve fails to close.

A standard electric water heater requires a 30 amp double pole breaker. These are basically two 15 amp breakers in their electrical panel. In some older homes, only a single 15 amp breaker may be available.  Installing a 30 amp model on 15 amp service would overload the breaker. It also does not allow it to run properly due to a lack of electricity.

For this reason and to give ProTerra more versatility a 15 amp model is available. The main difference is the downsized elements. The 15 amp model uses 2,500-watt elements instead of the standard 4,500-watt elements in standard electric water heaters.  The first-hour rating of the 15 amp model is 54 gallons per hour. On the other hand, the 30 amp model’s first-hour rating is 67 gallons per hour.  The recovery time for the 15 amp model is 16 gallons per hour compared to 27 for the 30 amp model.

As you can see by the highlighted section of the spec sheet, the first-hour hot water delivery and recovery rate is much less on the 15 amp than the 30 amp because of this.

It’s been many years since homes were built without having a 30 amp service ran for their water heater and is pretty rare to come across.

The 15 amp variant became available during Rheem’s Gen IV launch in 2017.

If you are replacing any standard electric water heater, chances are that it would be a 30 amp model. If you had any doubts, the only way to verify would be to look at the electrical panel and see what size breaker is present for the water heater circuit.

All hybrid heat pump water heaters have a condensate drain to remove water that has condensed from the warm air drawn into the water heater by the compressor to heat the water in the tank.

Review the manufacturer’s instructions when installing a condensate drain line and make sure that your drain lines connections and piping comply with all state and local codes.

Below are some considerations for the proper draining of condensate:

  • A floor or other drain no higher than 36″ (91.4 cm) above the floor must be available in close proximity to the water heater to allow for the shortest possible drain with minimal turns to be installed.
  • It is important to install a 3/4″ FNPT fitting suitable for either rigid or flexible line to the primary drain port coming off the side of the unit. Diameter reductions from the 3/4″ drain line are not recommended.
  • It’s important to route the flexible or rigid line that the discharge water cannot contact live electrical parts or cause water damage.
  • Ensure that the rigid or flexible drain line maintains a downward slope to allow for proper gravity drainage of condensate to the drain and to allow for proper function of the condensate drain blockage sensor.
  • If no drain is available then install a common condensate pump with a capacity no less than 1 gallon (3.8l)/day according to the manufacturer’s instructions.
  • If a condensate pump is installed, it should be wired to shut off the heat pump in the event he condensate pump fails or the float switch in the pump activates.
  • Condensate drain lines that are installed in areas subject to freezing temperatures should be wrapped with a nationally recognized heat tape.
  • You shouldn’t connect condensate drain lines with other drain or discharge lines into a single (common) pipe or line. Each line (condensate drain line, temperature and relief valve discharge pipe, etc.) should be independently run to an adequate drain.

 

Zwell strives to have a positive impact on household energy consumption globally. Aside from offering energy-efficient alternative products, we strive to give information on heat pump water heater rebates and tax incentives. That is why we are constantly working on solutions to provide instant discounts at the time of purchase. However, rebates are often provided by the utility provider or through the Federal Government tax credit.

Our goal is to make this process as simple as possible for everyone. Nevertheless, if we are unable to provide you with a heat pump water heater rebate immediately, we will provide you with the information and procedures necessary to claim a refund or tax credit.

For more information on rebates and available tax extensions, visit the Rheem Rebate Center or the Energy Star Web Rebate Finder website.

For additional questions, do not hesitate to get in touch with us.

A heat pump or hybrid water heaters transfer heat from the surrounding air to the water. As a result, it will produce cool, dry exhaust air. Today’s hybrid water heaters have the capability to run in 2 modes. The first mode is heat pump mode, this is the most energy-efficient mode. The second is conventional electric resistance mode. The second mode is less energy efficient than the first mode.

However, when operating in heat pump mode, it does not heat water as fast as conventional electric resistance heaters. This is most especially true when the water heater is recovering after significant usage.

Consequently, to maintain performance, hybrid water heaters may switch between the two modes. These two heating modes are why heat pump water heaters are also referred to as “hybrids”.

Hybrids are optimally designed to be installed in unconditioned or semi-conditioned areas. For example, garages or basements. However, if placed in conditioned space, hybrids will produce cool and dry air that is useful in the summer months but will lead to higher heating bills in the winter months. If you think a heat pump water heater is the right product for you but you need to install the hybrid in a conditioned space such as a laundry room, you have the option of ducting the exhaust air outside.

General Hot Water Heater Questions

When your house experiences flood, fire, earthquake, or other physical damage; refrain from using the water heater. We are sorry to hear that you have to go through this. We can only imagine how difficult this has been. However, once it is safe to be in your home you should turn off the circuit breaker to the water heater first.

Do not hesitate to contact us so we can help determine if it is safe to continue to operate your water heater.

Seismic straps are also known as earthquake straps or water heater restraining straps. These are straps that brace or anchor your water heater to the wall. They prevent the water heater from falling when an earthquake happens.

We follow all local and national codes when installing your water heater. We install seismic straps with every water heater installation up to or exceeding the codes governing your home. For seismic strapping information in Oregon, you can read this.

If we are the one installing the new water heater for you, we will help you verify if there is a need for a thermal expansion tank. Moreover, you can also check with your water utility if there is a need for an expansion tank.

Heated water increases water pressure. This is because the water expands in volume when heated. Thermal expansion is the term pertaining to this effect. For an “open water system”, an increase in water pressure that exceeds the limit of the water heater can flow back into the city main. Hence, dispersing the excess pressure. There is no need for a thermal expansion tank.

However, a “closed water system”, prevents the expanding water from moving back into the main supply line. As a result, thermal expansion can build an unexpected dangerous pressure increase in the water heater system and piping. During each heating cycle, this rapid pressure increase can trigger the pressure relief valve repeatedly causing untimely breakdown.

The recommended method of managing this is to connect a thermal expansion tank. In the cold water line between the water heater and check valve, this is where the expansion tank should be installed.  It is designed with an air cushion that decreases as the system pressure increases. Therefore, reducing the pressure build-up and repeated operation of the pressure relief valve.

First and foremost, when setting the temperature of your hot water heater you need to consider the safety for you and anyone that will use hot water in your home. By far the biggest safety factor to consider is injury from scalding or burns related to exposure to hot water. Water temperatures above 125°F (52°C) can cause severe burns instantly or death from scalds.

Children, elderly and disabled individuals are at the highest risk of being scalded. Households with these people may require a 120°F (49°C) or lower thermostat setting to prevent contact with water capable of injury. Always feel the water before bathing or showering. The chart below can act as a guide for determining the proper water temperature for your home.

TemperatureTime to Produce a Serious Burn
120°F (49°C)More than 5 minutes
125°F (52°C)1.5 to 2 minutes
130°F (54°C)About 30 seconds
135°F (57°C)About 10 seconds
140°F (60°C)Less than 5 seconds
145°F (63°C)Less than 3 seconds
150°F (65°C)About 1.5 seconds
155°F (68°C)About 1 second

To comply with safety regulations most manufacturers factory set the water heater temperature to 120°F (49°C). The US Department of Energy also recommends 120°F (49°C) as the optimal setting to balance safety and conservation.

Another important safety consideration is that in certain environments legionellae bacteria can build up in storage water tanks and plumbing, which can cause Legionnaire’s Disease or Pontiac Fever. If you or someone in your home has an immune compromised system or a chronic respiratory disease you should take additional precautions to make sure your plumbing system is providing you with safe water, which may require hotter temperatures and additional maintenance.
