Whether you’re tired of running out of hot water in the middle of a shower or simply want it to reach the bathroom in less than the 20 seconds it should take to wash your hands, you’ll find dozens of on-demand options available, sized for your needs and climate. Consider that a single company, EcoSmart (an offshoot of Rheem), offers at least three tankless heaters sized for whole-house use, plus two lines of mini tankless and plug-in point-of-use (POU) heaters. Each mini line offers units in four sizes. Intended for hard-wired and plumbed installation, the POU heaters measure a compact 11″ long x 6″ high x 3″ deep, meaning they’ll fit under a small lavatory sink. Rated from 3.5 kW to 6.5 kW, these units deliver between .5 and 1.4 gallons per minute. (The actual amount of flow varies according to the inlet temperature of your groundwater. Residents of Florida, for example, might easily reach the maximum output with a less powerful unit than someone in Maine.) Lack the necessary wiring or plumbing to accommodate a tankless heater? The versatile quartet of redesigned ECO MINIs plug into standard outlets. Like the tankless POUs, their compact size means they fit into small spaces like workshops, outdoor sinks, or recreational vehicles.
FLO monitors water leaks as little as a single drop per hour. The device also permits the user to set conservation goals.
Leak detection
A newer wrinkle in plumbing protection are water monitors that can alert you by smartphone if a major leak is in progress. StreamLabs’ Smart Home water monitor , for instance, mounts on the main water line and uses ultrasonic technology to detect leaks. It installs on copper, PEX, or PVC piping in just a few minutes, no plumbing skills required. The monitor, which retails for under $200, works best when paired with a more expensive control unit ($599) that will automatically shut off water valves should the pipes spring a leak.
Another highly rated monitor, FLO from Moen , claims it can sense leaks as small as one drop per minute. FLO will also monitor daily water usage and allow you to set conservation goals (the most detailed data requires a monthly subscription service). Units are sized to fit pipes ¾” to 1 ¼” in diameter. The all-in-one system costs about $500. Some users say it’s easy to install, but Moen recommends calling a professional plumber.
Evaporative Cooling
Long a staple of hot-weather comfort in the dry Southwest, evaporative coolers are not new. What is new is the idea of a portable cooler that can quickly cool large areas in minutes without being noisy. Cold Front , introduced this past summer, is a series of evaporative coolers that can cool spaces from 800 to 6,500 square feet without making a racket. While most units in the series are intended for industrial or commercial cooling, the smallest unit, the ultra-quiet Cold Front 100, can cool an area of up to 800 square feet. It operates at 60 decibels. That’s about the level of normal conversation.
Small but powerful, the Cold Front 100 from Big Ass Fans can cool indoor and outdoor spaces by up to 30 degrees without disturbing the flow of conversation.
Like a breeze blowing across a lake on a hot day, evaporative coolers work by passing hot outdoor air over water-saturated pads. They then expel water-cooled air, lowering the ambient temperature by 20 degrees or more. Since they don’t use coolants or run compressors, evaporators are much cheaper to use than air conditioners.
The Cold Front units are powered by virtually silent direct-drive motors and variable speed controls. (Even the largest, the 500, operates at 60 db.) They plug in to a standard 110-volt outlet and draw water from a standard garden hose . The smaller units ($700 to $900 each) are best suited for spot-cooling work spaces, garages, and patios.
Drain and clean an evaporative cooler regularly to remove sediments and minerals. Plan on a major annual cleaning, plus routine maintenance during the cooling season. In hot climates where the cooler operates much of the time, look at pads, filters, reservoir, and pump at least once a month. Replace the pads at least twice during the cooling season.
See-through Windows
Windows in older houses aren’t as leaky as replacement window manufacturers would have you believe. Still, installing exterior or interior window inserts may result in increased comfort and energy savings, averaging between 15 and 23 percent of energy costs. Better yet, these “supplementary” windows usually sell for one-third to one-half that of high-quality replacement windows—without sacrificing the original sashes or casements.
A worker for Allied Window installs a compression-fit window at President Madison’s Montpelier in Virginia. Most makers of inserts and historically sensitive storms have a long list of historic and institutional clients.
Exterior storm windows improve thermal performance and help make existing windows more airtight. They also reduce drafts from convection currents and provide some protection from the weather for the existing window. The downside has always been that they cover up the old, historic window. Mon-Ray and Allied Window , two companies that work on historic sites and houses, have come up with ingenious ways to disguise the appearance of an exterior storm, including custom paint colors and finishes that closely match the existing frames and sashes. In addition to fixed windows, both companies make operable units (some with between-the-glass blinds and options like mullions) and can fit openings with such complex shapes as oval, round, or radius.
Interior window inserts—sometimes called thermal compression windows—can have glazing of polycarbonate, acrylic, or glass. Panels typically install in the inner frame of an existing window by spring tension, flexible compression, or magnetic attachment. Like an exterior storm window, the interior inserts improve air tightness, thermal performance, and, users say, interior comfort because they prevent drafts. They’re also easier to install than exterior storms and do not compromise the historic appearance of the window outside.
Thermal compression windows, like these from Indow, can extend the seasonal use of a room that has many windows.
Thermal compression windows made with acrylic, like those from Indow and Climate Seal , are arguably better insulators than glass and, inch for inch, weigh half as much. They can be made with UV-blockers to reduce sun-induced fading. And while some types of exterior storms have proven superior at noise reduction, both Indow and Climate Seal offer thicker, acoustic-grade glazing capable of reducing noise by up to 70 percent.
