How To Install A Heat Pump Water Heater

Measure the temperature of the hot water from your current water heater by running the sink or shower for into a saucepan 3 minutes and taking the temperature with a low temperature cooking thermometer. Y'all'll want to utilize this as the setpoint for your hybrid h2o heater.

Start by turning off the power to the existing water heater at the breaker box. Double-cheque by removing the water heater's junction box cover plate and property a voltage meter adjacent to the wire connections. If information technology does not low-cal up, the excursion has been properly close off.

At present it'due south time to drain the one-time water heater. Hook up a hose to the water heater drain and open the valve, leaving the cold water supply open to flush out any droppings. So, shut off and disconnect the common cold water supply and let the tank drain completely.

Draining the tank tin can take time and may require cleaning out sediment in the bleed valve and/or the hose. If gravity alone isn't enough to clear the tank, you lot may demand a small pump designed to move h2o.

When the tank is empty, remove the flex supply lines and disconnect the power. If flex lines are already connected to the supply, there should be enough of pipe to which you can connect the new fittings. Otherwise, be sure to leave iii–v inches of pipage for the new connections.

Remove the temperature/force per unit area relief valve plumbing, and if reusable, salvage information technology for reinstallation on new h2o heater. Remove the electrical wire nuts, but don't cut the length of wire until yous know what is needed for the new heater installation.

Remove the old water heater.

Tip:

Earlier you take your old h2o heater to the landfill, check to see if your waste management provider has an apparatus recycling program.

Clean upwards your working infinite to prepare for installing the hybrid water heater.

Inspect all remaining fittings to make certain they are audio and functional. If they demand to exist replaced, at present is a great time to do it. If you are replacing the cold water valve, you will need to shut off water to the whole house.

Materials: Water supply pipes; Shutoff valve; Pipe for temperature and force per unit area relief valve; Teflon tape; Mixing or anti-scald device (optional); Pressure reducing valve (optional); Thermal expansion tank (optional); Construction channel or wood blocking (optional)

Your new hybrid water heater may require a couple of changes to the location and plumbing. First, your hybrid water heater may take a larger diameter than your old h2o heater, and six inches of clearance from the wall is recommended. Refer to the installation manual for clearance requirements around the frazzle fan.

Tip:

Use structure channel or wood blocking to space the hybrid water heater away from the wall. This can help secure seismic strapping and reduce vibration transferring from the straps to the wall.

The hot water outlet on this heat pump water heater is located on the side of the tank.

Second, different the onetime water heater, the h2o inlet and outlet lines on some electric hybrid water heaters may be located on the side of the unit instead of on top. You volition need longer supply lines to accomplish the inlet and outlet. Employ solid pipe and flexible pipe connections if they are permissible according to local code. These exercise non require soldering, clamps, unions, or glue. Use Teflon tape on all threaded connections.

Tip:

Do not reuse the old piping — information technology's not worth the risk of leaks.

If you are installing your water heater in a closed water system, which lets water in through the supply line and doesn't let it dorsum out except through drains and sewer lines, you will demand to install a thermal expansion tank to prevent problems resulting from pressure level buildup. Install the temperature and pressure relief valve and a belch line per the manufacturer's instructions and local code.

Install a shutoff valve in the cold water inlet line well-nigh the h2o heater. If y'all are not using flex connectors, use unions in the hot and cold water supply lines to make removal of the water heater easier for service or replacement. If required past local lawmaking, install a mixing valve or anti-scald device in the domestic hot water line and a pressure reducing valve in the cold water inlet line.

Materials: Bleed pan; Rigid insulation foam pad; Seismic strapping; Shims (optional); Stand (optional)

Place the rigid foam pad and drain pan for the hybrid water heater on the floor, or if local code requires, place the bleed pan atop a stand up. Move the water heater onto the drain pan. Ensure that the control panel is facing outward for like shooting fish in a barrel access. Level the unit using shims, if necessary.

If required by local code, install seismic strapping.

Materials: Piping insulation (optional)

With the hybrid water heater in place, connect the supply lines to the common cold water inlet and hot water outlet.

Tip:

Insulate the hot water supply line with a polyethylene or neoprene foam pipe sleeve. This reduces rut loss and tin can raise water temperature 2–4 °F hotter than uninsulated pipes tin can deliver. You besides won't accept to look equally long for hot water when you turn on a faucet or showerhead, which helps conserve water and maximize energy savings.

Materials: PVC piping; Condensate pump and vinyl tubing (optional)

Unlike your sometime h2o heater, the hybrid unit produces condensate that needs to exist drained. If there is a nearby floor or sink drain, attach PVC pipe to the water heater's drain port(s) and road the condensate in a downward slope.

Tip:

Rather than using an elbow to connect the condensate line to the tank, use a tee fitting with an unglued cap that can exist removed for easy cleaning access.

If there is not a bleed nearby, a condensate pump is required. Refer to manufacturer instructions before connecting the condensate bleed line into an existing drain or belch line. Most condensate pumps can be attached to a wall hanger and plugged into a standard 120 Volt outlet. Ensure that the tubing is connected securely with hose clamps to the pump output and drains to a suitable termination point. If a drainage pipage is directed outside, make sure the pipe will not freeze by having it terminate at least vi inches above the ground, and making sure there are no low spots in the tubing outside. Install the condensate pump per manufacturer instructions. Verify the pump is working properly by filling it slowly with h2o until the pump engages.

Tip:

The tubing from the condensate pump may need to exist routed up and over the surrounding rooms. To assist pull the tubing through insulation and/or areas with limited access, adhere a long PVC pipe to the tube and gently pull the tube through. Tubing and piping hangers can be installed on condensate lines to preclude slippage and achieve a cleaner look.

Open up the cold h2o valve slowly at first to make sure at that place are no leaks. And then, fill the hybrid water heater. Meanwhile, turn on the highest hot water faucet in the house to allow air to escape as the tank is filled and double-cheque the piping for leaks. Don't worry if some rusty water gets pushed through. When the hot water faucet in your house has a steady stream, yous'll know the tank is full. Run the faucet for iii minutes after a constant flow has been achieved earlier turning it off.

When the tank is total, connect to the electrical supply according to the manufacturer's instructions. Use new properly sized wire basics to connect the wires. And then, plough on the power to the hybrid h2o heater at the breaker. Use a voltage meter to verify proper voltage. Brand sure all cover plates are properly installed.

Virtually h2o heaters volition go through a self-check and verify that the tank is full of water, that information technology has sufficient power, and that in that location aren't whatever errors. This can take up to five minutes (y'all may hear a serial of clicks and the fan may turn on and off). The first heating may use electric resistance to deliver hot water to you as quickly as possible, even if the unit is set to Hybrid or Oestrus Pump mode The compressor and fan will non operate until the water has reached a sure temperature. Your hybrid water heater volition default to Hybrid style. This setting is ideal for daily apply considering it uses the heat pump primarily, activating the less-efficient electric heating elements only when demand is loftier. Refer to the manufacturer's instructions for information on other operating modes. Using the digital controls on the hybrid electrical water heater, set the water to the temperature you measured in the first. Congratulations! You've successfully installed your new hybrid water heater, and you lot're prepare to enjoy years of reliable hot water and savings.
