Water Heaters

In Ottawa we have three main options for water heaters.  The conventional tank, a power vented tank or instant hot water tanks.  Many large corporations also rent hot water tanks.  We can help you do the math to determine if it’s best to own your tank and which type to go with.

Pool Heaters

Pool Heaters

Extend your summer by installing a pool heater.  The size of heater you need depends on a number of factors; do you have an above ground pool or below and the overall size of your pool.  We also need to look at how far your heater will be from your gas meter.  All those details we can help you with, what’s important is that you can enjoy a warm pool from May into September!
