Rinnai combi boiler installation and service across Toronto and the GTA — durable, high-efficiency heat and on-demand hot water. Installed by a licensed gas technician and TSSA registered contractor.
Known for heat-exchanger durability and dependable performance — a combi built to go the distance.
Durable stainless-steel heat exchangers give Rinnai combis a reputation for long service life and steady, reliable operation year after year.
On-demand domestic hot water with no storage tank — a properly sized Rinnai keeps up with everyday household demand.
Condensing design and PVC venting mean less wasted gas through Ontario's long heating season, and lower operating costs.
We install both Rinnai and Navien combi boilers, so we have no reason to push one over the other. Navien is the most common combi in Ontario, with excellent hot-water flow and the widest parts network. Rinnai's strength is durability — its stainless heat exchangers are built for the long haul — and rock-steady reliability.
For your home, the better choice comes down to peak hot-water demand, budget, and your heating layout. We'll size both options, explain the trade-offs in plain language, and let you decide with full information. Whichever you pick, the install quality — clean near-boiler piping, correct venting, proper commissioning — matters more than the badge on the front.
