Tankless Water Heaters: Tips on How to Maximise Its Performance

December 3rd, 2018

Super-efficient tankless water heaters, wall-mounted so that they save closet space, are recognized as potent energy saving systems. Once installed, smaller utility bills quickly arrive on a home’s doorstep. Arguably, this money-saving strategy could happily stop right there, with the equipment owner sitting down to enjoy the cozy, toasty warmth while sipping a hot beverage. Exceeding all expectations, however, we’re making it our mission to grab even more savings.

Winter-Temperature Sized

Tip number one takes us straight into the heart of a cold winter. There’s a knee-high snowdrift outside, but the occupants of this home are prepared. They talked to the heating engineer and selected a tankless water heater that can supply enough litres of hot water a minute to satisfy the most sensitive tenant. Take note, winter climates mean less hot water because the water enters the structure colder.

Making the Most of Venting Strategies

Be vent sensible. If the appliance exhausts are directly exposed to a strong wind, system efficiency drops. Intelligently provide shelter and shields for those important wall openings. Moreover, keep the vent ducts free of choke points. A few metres of unhindered ducting keep tankless water heaters respiring properly.

Plan for Seasonal Variables

The snow and wind hit the vents hard. The water temperature drops, so it takes longer for the appliance to restore thermal energy. The seasons introduce hard to predict functionality factors. Clear autumn leaves from the vents, listen to snow advisories, and account for extra condensation issues when a hot and humid summer spins back around.

Match System Features to User Expectations

For instance, ask a product representative to show off the specifications page in the user manual. In this often overlooked manual page, the rep should be able to describe flow rates and capacity figures without any difficulty. If any of these figures don’t make the grade, when compared to a stated region’s seasonal trials and tribulations, look elsewhere.

Know About Point-Of-Use Models

Smaller and more localized than a conventional whole system tankless water heater, point-of-use appliances cut costs further while they save energy. As a drawback, however, they’re defined as location-dedicated systems, which can only maximize hot water supplies close to a single outlet.

Like any other high-performance piece of equipment, tankless water heaters save energy as soon as they’re pushed into service. That feature alone might just persuade a user to become complacent, however. Going the extra mile, a diligent heating engineer polishes and sharpens and fine-tunes system performance. This is done by sizing the heater, measuring flow rates, planning for seasonal challenges, and by streamlining every appliance-regulatable feature.
