A 22 gallon tank is only suitable when it is expected that there will be minimal hot water usage (ie in offices, stores and individual washrooms), or when there are space restrictions. Typically a 40-gallon size water tank is suitable for up to four persons and a 60-gallon size water tank is suitable for five or more. Sizes larger than this may be necessary, and can be tailored to your needs.
This safety valve is a pressure / temperature relief ( PTR ) valve (see Product Features). This valve opens when the pressure in your plumbing system exceeds 150 lbs/sq in (1034 kPa) or if the temperature exceeds 210°F (99°C). If this particular valve appears to be leaking, you should contact us and we will send a repair specialist to come and check your water heater immediately, 24 hours a day, 365 days a year.
Your NB Power-rented water heater is factory set at 140°F or 60°C, which is the temperature recommended by the World Health Organization for potable (safe for human consumption) water to help protect against harmful bacterial build up inside the water heater tank. To reduce your water temperature at the point of use, we suggest that you contact a licensed plumber to discuss options such as a mixing valve or tempering device.
When you rent a water heater from us, you are renting a 24-hours-a-day, 365 days-a-year service guarantee. The monthly rental fee is added to your electric bill making it convenient and worry free.
Service calls for owner water heaters can cost up to $100 for the visit alone. Parts are extra. Renting a water heater from us includes free 24-hour quick, reliable, service.
Shut Off Valve
We require our customers to have their plumbing up to code prior to performing maintenance/replacement of our water heaters.
Since 1970, the Canadian plumbing code requires a shut off valve be installed on the cold water line to isolate the water heater.
- Ensure that there is enough space for our technician to safely work on the water heater.
- There is nothing blocking the water heater and nothing blocking the pathway (snow, boxes, walls, appliances, etc) to the water heater.
- If the tank needs to be changed that there is enough space and access for our technician to safely take the old water heater out and carry a new water heater into the home.
40 and 22 gallon water heaters require:
- Voltage 208 or 240
- Conductor Size 12/2
- Fuse Size 20 amps
A 60 gallon water heater requires:
- Voltage 208 or 240
- Conductor Size 10/2
- Fuse Size 30 amps
Please note: When downsizing from a 60 gallon water heater to a 40 or 22 gallon model, the wiring does not need to be altered.
- PEX (Cross linked PolyEthylene)
- CPVC (Chlorinated Polyvinyl Chlorine)
The location of the water heater should be close to a free flowing floor drain or other acceptable means of directing the water to a safe location of disposal.
