Choosing the right system:

When it’s time to upgrade your existing boiler there are many options to choose from. City Home Comfort will help you decide the right make, size and model that is ideal for your home. Having the correct size is imperative to the function of your Central Heating System.

Many condominiums and townhomes in Toronto have a Boiler tank unit that is very large, and at at an age to where it can leak. Home insurance does not cover damages to property for tank boilers that are over 10 years old.

An upgrade to a Rinnai i-Series boiler is the best solution for a long lasting upgrade for small spaces, like closets, and much cleaner hot water.
