If you decide that a tankless water heater is a good idea for your home you should consider the requirements that your house will need to meet first. Tankless systems have a number of additional needs over your conventional tank water heater. We install more Rinnai than any other system so I will give the specifications for this system, although they are all quite similar.

A 3 FT clearance is required for the following:

- a. Windows

- b. Any exhaust outlets – Furnace, dryer vent, kitchen vent etc.

- c. Gas Meter – The vent needs to be at least 3 feet from the gas meter and the pressure relief valve.

The vent also needs to be 1 foot above grade and cannot be vented into any shared walkway that is less than 5 feet wide.

This diagram should help explain it.

Or get a Free in home consultation and have an installer who really knows “the tricks of the trade” help you find a spot for your Rinnai Tankless water heater. And as we all know installation can be tricky in Canada with existing gas codes and venting requirements.
