On-Demand Water Heaters: Energy Efficiency at Its Best


Whatever you do today at home should be somehow related to energy efficiency. From the lights, to household appliances and water heaters, it is all about saving energy to help the environment. As we know, there are already energy-saving light bulbs, most of the modern appliances have the Energy Star rating and now it is time to install more productive water heaters. If you have been using an ordinary electric water heater and you see it is counting its last days, think about a tankless heater.

Water Standby – More Energy Waste

The first thing that is obvious when it comes to tankless heaters is that they do not have a tank. The problem with regular water heaters is that they heat a certain amount of water and then the thermostat prevents further heating and the heated water stays in the tank until it is used again. So, what seems to be the problem?

Well, the once-heated water is just kept lying there in the tank, wasting the heat and getting cold. So, when you turn on the faucet, you start the whole water heating-thermostat regulating-water lying procedure, which simply wastes electricity.

When you install a tankless heater, you will see that it takes less space and you have more storing options in the room where you keep the heater. Also, these devices do not keep water inside them, since they have no space for that, but they heat it as it flows through them.

Simply, when you turn on the faucet, the water flow alerts the sensors which signal the computer unit that it should activate the heat exchanger and start heating the water. No electricity is used without being transferred directly to the flowing water.

If you decide to have a tankless heater installed in your home, you have to opt either for an electric or gas heater. The decision will depend on your needs and your budget, of course. Gas heaters are more expensive and they are more delicate in terms of installation and maintenance.

On the other hand, electric tankless heaters have a much easier installation procedures and they also require less demanding maintenance. The key elements in deciding which one to choose are the electricity price and the gas availability in your region.

Mostly thanks to the fact that there are no electricity wastes since there are no standby periods, going for a new tankless heater could help you make a significant annual electricity-saving, say highly-rated Hazlet plumbing experts.

However, there are a few factors that affect the overall efficiency of such a heater. Firstly, the number of people living in the household; secondly, the frequency of parallel demands for hot water; finally, you have to regularly maintain it to prolong its life, which is expected to be at least twenty years, if treated properly.

What about the Drawbacks?

In spite of all the hype about energy efficiency, there has to be a catch. Actually, the efficiency part is pretty straightforward: by installing a tankless water heater of any kind, you do save electric energy.

The problem that you might face is wasting water. The critical period is the one between the point when water starts rushing out of the faucet and the point at which you actually get hot water. That first cold water should be collected, however, and used for watering the plants or flushing the toilet. That way you will reduce the waste of clear water.

Investing in your home is a constant process. You cannot just give it up and say “I’ve done enough”. Old-school storage water heaters demand detailed maintenance. Those new tankless fellows are here to make your life easier and less expensive, so choosing them after gaining enough information could be the real thing.
