Before spending capital on an air-to-air heat recovery system, any serious buyer asks the same question: how long until it pays for itself? The answer is not a mystery and it does not need specialist software, a spreadsheet and a clear method give a defensible simple-payback number that survives scrutiny from finance and from the energy code reviewer alike. This article lays out the core formula, walks a fully worked example, lists what to include in the cost side, and flags the two mistakes that make most amateur payback estimates either wildly optimistic or needlessly pessimistic.<\/p>\n

What to include<\/h2>\n

The cost side is where estimates go wrong. Capture the full installed cost: the core, its housing and bypass, control integration, labour, and any duct or curb modifications. Add a maintenance line, plates and wheels need periodic cleaning and occasional gasket or bearing service. Then subtract applicable incentives, many utilities and some jurisdictions offer rebates for energy recovery that meet code thresholds, which can cut the effective cost by 10 to 30 percent. Finally, run a sensitivity on fuel escalation: energy prices tend to rise, so a payback calculated at today’s price is conservative, and showing the 5- and 10-year cumulative cash position is more honest than a single payback number.
