70% of Whitby homes are single-detached houses, and a full house of showers asks a lot of one water heater. GT Home Services rents, installs and repairs water heaters, furnaces and heat pumps from Port Whitby to Brooklin.
*Includes standard installation only. Any extra work your home needs is quoted before we start.
Prices before HST. You approve every repair price before we begin.
📞 Call (647) 677-0037Most Whitby water heater calls come down to one choice: rent a tank, rent a tankless unit, or buy one outright. Rentals include the installation and every repair, and same-day installation is available on many jobs. Monthly rates for the models most Whitby houses need:
| Water heater | Type | Monthly rent |
|---|---|---|
| Bradford White CV40 | Tank, chimney vent, 40 gallons | $21.99* |
| Bradford White CV50 | Tank, chimney vent, 50 gallons | $25.99* |
| Bradford White PV50 | Tank, power vent, 50 gallons | $33.99* |
| Bradford White PV60 | Tank, power vent, 60 gallons | $40.99* |
| Navien NPE-180S2 | Tankless, 2 to 3 bathrooms | $37.99* |
| Navien NPE-240S2 | Tankless, 4 to 5 bathrooms | $43.99* |
| Navien NPE-240A2 | Tankless with recirculation, 4 to 5 bathrooms | $49.99* |
*Includes standard installation only. Any extra work your home needs is quoted before we start.
Before HST. Every size and vent type is on our water heater rental page.
Owners who would rather buy usually go tankless. A Navien NPE-180S2 is $3,111 installed, a Kepler 199 for three or four bathrooms is $3,333, and the NPE-240S2 for four or five is $3,555. A tank that leaks from the bottom has reached the end; a tankless unit showing an error code or running lukewarm often needs only a repair or a descale. Renting from another company? We install the new heater and the old one goes back to its owner, on their terms. See water heater repair and switching providers.

Durham Region's Whitby Water Supply Plant draws Lake Ontario water through an intake about 1.7 km long, set roughly 16 m deep, and can treat 118,000 cubic metres a day for Whitby, Brooklin and neighbouring towns. Durham reports 125 mg/L of hardness for that lake system. The Region does not require a softener; on a tankless heater, a yearly flush (included in our rentals) handles the scale instead.

86% of Whitby homes are houses or townhouses, almost all on ducts. A central heat pump replaces the outdoor AC unit, cools the house in summer and heats it through the mild part of winter, while the gas furnace stays for the deep cold. Expect $4,500 and up installed or $54.95 a month; a ductless head for a room the ducts never reached well starts at $2,800. Our high-efficiency models work down to -25°C. See heat pumps.
