One compact, high-efficiency unit for both your heating and your hot water. Navien and Rinnai combi boiler installation across Toronto and the GTA — by a licensed gas technician and TSSA registered contractor.
A combi boiler does the work of two appliances in one wall-mounted unit — the modern choice for homes with hot-water (hydronic) heating.
A combi replaces both your boiler and your tank water heater with one compact wall unit — heating your home and making hot water on demand.
No tank to run dry or reheat. Hot water is produced the instant you open a tap, and a high-efficiency condensing combi wastes far less energy than a standing tank.
Reclaim the floor space your old boiler and tank took up, and cut gas use with 95%+ efficiency and PVC venting.
Combi boilers suit most GTA homes — especially older houses replacing a bulky boiler and a separate tank at once.
Fixed-price written quotes before work begins. Unit, permit, and TSSA inspection included.
