Is your system working harder than it needs to?

Many hydronic heating and cooling systems waste energy by operating sometimes over-sized pumps at full capacity while simultaneously restricting flow with a valve. That's like hitting the gas and slamming on the brakes at the same time!

Toronto Hydro's new PUMPsaver program is an end-to-end solution to optimize your hydronic systems. It's offered free of charge. If you qualify, we'll arrange for a professional to add variable frequency drives (VFDs) to pumps and then balance them so they run according to their actual, rather than maximum, demand.

This simple two-step process typically reduces electricity use by up to 35% – that's ongoing savings of $4,000 to $20,000** (estimated, depending on the pump size) in electricity costs a year.

*Projects average a value of $10,000 to $15,000.

**Based on a 35% reduction in the pump's electrical consumption in a heating and cooling system and electricity costs of $0.15/kWh.

We measure and verify savings

Pumps will be metered and monitored to determine savings. As the hours of operation of the pumps are continuous and consistent, pre- and post-measurement of electrical loads associated with the pumps will be relatively short in duration.
