Green Services


CNJ Services offers a wide variety of energy efficient green product options. There are many ways in which you can save money and help protect the environment in your home. CNJ Services can help you meet your energy saving and environmental goals and keep your costs down. Here are a few ways in which you can save money and natural resources:

High-efficiency, water-saving toilets

Toilets are often the source of the most water use (and water wasting) within a home; accounting for nearly 30 percent of an average home’s indoor water consumption. If you have a toilet(s) that uses more than 1.6 gallons of water per flush (gpf)—as do almost all toilets installed before 1994. CNJ Services recommends replacing your older toilet with one of the following:

  • High-efficiency (or ultra-low-flush) toilet model that uses no more than 1.3 gpf (the current EPA WaterSense standard, as of 2010)
  • Dual-flush toilet, which has a lower-flush button for liquid waste and a higher-flush button for solid waste; this type of toilet is common in Australia and Europe and is becoming increasingly popular in the U.S. (Dual-flush conversion/retrofit kits are also available to convert a regular toilet into a dual-flush.)
  • Composting toilet, which uses little to no water for flushing.

In California, new legislation has mandated that all new toilets sold or installed in the state after 2014 must be high-efficiency toilets. At some point, federal standards might also be raised to this standard. For commercial/office-building bathrooms, install ultra-low-flush (ULF) urinals in lieu of regular urinals.


Showering accounts for up to 20 percent of the average household’s indoor water use. You can cut your shower water use by as much as 70 percent by switching to an ultra-low-flow showerhead, which is easy to do. CNJ Services only installs high-efficiency showerheads that will give you a good strong shower stream. If you have an old or inefficient showerhead (one that uses more than 2.5 gallons of water per minute: gpm), CNJ Services can replace it with a high-efficiency / ultra-low-flow showerhead that uses no more than 2 gpm (the current EPA WaterSense standard, as of 2010). Be aware: Those “luxury shower towers” or pie-plate-sized, monsoon-downpour-imitating fixtures are major water-wasters; they can use as much as 20 gallons of water per minute! Using ultra-low-flow showerheads will also save you money on your energy bills, by reducing the demand on your water heater. According to the WaterSense program, a household could save 300 kilowatt hours of electricity annually, enough to power its television use for about a year.


If you have inefficient faucets (which use more than 2.5 gpm), CNJ Services can replace them with high-efficiency faucets that have a flow rate of no more than 1.5 gpm (the current EPA WaterSense standard, as of 2010) OR add a water-saving aerator or flow restrictor to the existing faucets (an easy and inexpensive modification). Some utility companies and cities offer rebates or other incentives for buying high-efficiency toilets or plumbing fixtures. Ask your CNJ Service Tech for more details.

Tankless Water Heaters

Tankless water heaters offer a proven alternative to the storage tank water heaters most commonly found in U.S. homes. Storage tank water heaters store 40 to 120 gallons of water at a time and constantly reheat that water regardless of how much is actually demanded. A tankless water heater is also called an “on-demand” water heater because it only heats water when you turn on the hot water tap. When you turn the hot water tap in a home with a tankless water heater, a powerful gas or electric heater kicks on and instantly heats water running through coils in the unit. Since water is only heated when you need it, you save on the costs associated with constantly heating and reheating a large tank of water. Tankless water heaters can accommodate the needs of large families and commercial buildings and can be adjusted for temperature just like the “old fashioned” storage tank water heaters. If you are looking to upgrade to a green water heater but not sure which one is right for your needs, give CNJ Services a call and we will help you decide. CNJ Services can help you understand the benefits of high efficiency appliances and systems including Federal and local tax credits and rebates. Just give us a call!

Hybrid Water Heaters

Hybrid water heaters combine the technology of tank and tankless conventional hot water heaters.

Traditional tank heaters heat from the bottom, with the air rising through the tank and exiting from the top, allowing a fair amount of heat to be wasted. Tankless models also heat from the bottom, but the water flows through copper pipes. However, tankless models have been criticized because they don’t store water and continually provide hot water to multiple places in your home.

The most obvious benefit of hybrid water heaters is their efficiency. Water heaters can be extremely energy inefficient, in part because their energy usage wasn’t regulated until 2008 [source: Green]. This is particularly concerning because they often use the most energy in a home — almost one-fifth of your entire energy use!

Solar Water Heaters

Solar water heaters—also called solar domestic hot water systems—can be a cost-effective way to generate hot water for your home. They can be used in any climate, and the fuel they use—sunshine—is free.

Solar water heating systems include storage tanks and solar collectors. There are two types of solar water heating systems: active, which have circulating pumps and controls, and passive, which don’t.

Most solar water heaters require a well-insulated storage tank. Solar storage tanks have an additional outlet and inlet connected to and from the collector. In two-tank systems, the solar water heater preheats water before it enters the conventional water heater. In one-tank systems, the back-up heater is combined with the solar storage in one tank.
