A heat pump water heater heats your hot water by pulling warmth out of the air around the tank, instead of heating it with an electric element alone.
We install these tanks in homes across Cape Breton, and we check the room before we quote to make sure the tank will work well there.
A heat pump water heater has a small heat pump built into the top of the tank. It draws in room air, takes heat out of it and moves that heat into the water.
It also has a regular electric element for times when the family needs a lot of hot water fast. Most of the time, the compressor does the work and the element stays off.
A heat pump water heater heats water more slowly than a standard electric tank, so size matters more. The number to look at is the first-hour rating, which tells you how much hot water the tank can deliver in a busy hour, such as two showers, the dishwasher and a load of laundry on a Monday morning. A household that runs out of hot water now needs a bigger tank or a tank with a higher first-hour rating, not the same size again. During the visit we ask how many people live in the house, how many bathrooms there are and when the heavy use happens, and the quote names the tank size and its rating.
Most heat pump water heaters have several modes. Heat pump or efficiency mode uses only the compressor, which is the cheapest to run but the slowest to recover. Hybrid mode uses the compressor most of the time and brings on the electric element when demand is high. Electric mode uses only the element, like an ordinary tank, and is useful if the basement gets too cold for the heat pump to work well. Vacation mode keeps the water just warm while you are away. For most Cape Breton households, hybrid mode is the right everyday setting. We set it up and show you how to change it on installation day.
The tank works best in a basement or utility room with plenty of space around it, kept above about 7 degrees Celsius. It needs room to breathe, a drain for the water it makes and a little more height than a regular tank.
The tank cools the room slightly as it works, which helps in a damp basement in the summer. We check ceiling height, drainage and the electrical circuit during the free visit.
A heat pump water heater has a small compressor and fan on top, so it makes a hum similar to a dehumidifier. That is fine in a basement or utility room but not beside a bedroom. It also blows out cool, dry air as it works. In a damp Cape Breton basement in summer that is a bonus, but in a small closed room it can make the space too cold for the heat pump to work, so the tank needs enough air around it. It pulls water out of the air too, and that water needs a floor drain, a pump or a line to a sump. The Home Energy Assessment rebate also requires the tank to be in conditioned space.
The price of a heat pump water heater is set after a free visit, because it depends on the tank size and how much plumbing and wiring has to change. The written quote shows each change on its own line.
As of October 30, 2026, there are two ways to get $800 back on an eligible ENERGY STAR heat pump water heater, but you can only use one. The first is Efficiency Nova Scotia's instant rebate, taken off the price at participating retailers in the province, with no assessment needed. The second is the Home Energy Assessment rebate, which pays $800 for an eligible tank whether it is under 56 gallons or larger, as long as it meets the efficiency and first-hour rating rules for its size. Under the assessment route, the tank must be installed by a certified plumber and must not have received the instant rebate. The quote says which route fits your job.
The best time to switch to a heat pump water heater is before the old tank fails. Once it leaks, you need hot water the same day and most people take whatever standard tank is in stock. If your tank is rusting at the base, leaking at the fittings or well past ten years old, it is worth planning now. Homes that make hot water with oil, through the boiler or a separate oil-fired tank, need a new hot water source when the oil comes out. A heat pump water heater is a natural fit for an oil conversion and can be quoted at the same time as the heat pump.
A heat pump water heater usually goes where the old tank sat, but it is taller and may need a different electrical circuit than the one feeding the old tank. Its condensate line also has to reach a drain. The plumbing side includes the water connections, the relief valve line and, where the code calls for it, an expansion tank. For the Home Energy Assessment rebate, Efficiency Nova Scotia requires the tank to be installed by a certified plumber. We check the circuit, the ceiling height, the drain and the floor space during the free visit, and any changes appear as their own lines on the quote.
Call (902) 201-6758 and tell us the size and age of your current tank. You can read about our other work on the home page.
No. A tank that got the instant rebate in store cannot also get the $800 Home Energy Assessment rebate.
It needs the room to stay above a certain temperature, which the maker lists. If the basement drops too low, the tank switches to its electric element, which still gives hot water but costs more to run.
It needs its own circuit sized to the model. Many can use the existing tank circuit, but some need changes. This is checked during the visit.
It hums like a dehumidifier while the compressor runs. Most people do not notice it from upstairs.
Not if the tank is sized with a good first-hour rating for your household and set to hybrid mode.
Yes, a little. The air filter on top needs cleaning and the condensate drain needs to stay clear. Draining some water from the bottom of the tank from time to time helps with sediment.

A ductless heat pump heats a room or an open floor plan through a slim indoor head on the wall, with no ductwork needed. It is the most common job in Cape Breton because most older homes were never built with ducts.

A whole-home heat pump system runs several indoor heads from one or two outdoor units, so every main room gets its own heat. It is the right choice when one head cannot reach the bedrooms, the basement or the far end of the house.

A ducted central heat pump sends warm air through the ductwork a house already has, the same way a furnace does. It suits homes with a forced-air oil or electric furnace and ducts in good shape.

An oil to heat pump conversion replaces most or all of the heat from an oil furnace or boiler with a heat pump. It cuts the oil bill, and in many homes it ends oil deliveries altogether.

A proper heat pump cleaning takes the indoor head apart, washes the coil and the blower wheel, flushes the drain line and rinses the outdoor unit. A wipe of the filters is not a cleaning.

Heat pump repair finds out why a unit has stopped heating, is blowing cold air, is leaking water or is showing an error code, and then fixes it. Most problems come down to airflow, drainage, a sensor, a board or the refrigerant charge.

A heat pump keeps a cottage or seasonal home dry and above freezing through the winter, then cools it in summer. It is often the cheapest way to heat a camp that is only used on weekends.
