Is a Tankless Water Heater Right for You?

Tankless water heaters became popular in Europe and Asia after World War II because of space constraints and a greater need for energy efficiency. Today, virtually all homes in Japan use tankless water heaters.

Tankless water heaters conserve energy because they only heat the water as it is used. Traditional water heaters store a supply of hot water whether it’s in use or not. Tankless water heaters also heat water 20% to 30% more efficiently.

Compared to conventional water heaters, tankless water heaters can save the average family about 30% on water-heating expenses annually. According to Consumer Reports, that translates into a savings of $70 to $80 per year.

Is a tankless water heater right for you? That depends. Tankless water heaters are more than double the cost of standard water heaters. And the average installation cost is $1,200, compared with $300 for conventional models.

But tankless water heaters have additional benefits: They last twice as long, on average 20 years. And they provide a constant stream of hot water unlike storage-tank models, which stop providing hot water after heavy usage.

If you’re considering a tankless water heater, it’s best to consult with a plumber to determine your household water flow rate, which is the gallons per minute of water used by your fixtures and appliances. Undersizing the flow rate of a tankless water heater is a common mistake.

Tankless water heaters are available in propane, natural gas or electric models. Gas-powered are the most efficient. Manufacturers of tankless water heaters include Takagi, Paloma, Rheem, Rinnai, Stiebel Eltron and Bosch.

    1. Change the onboard thermostats to our available tamperproof versions. An electrician could easily facilitate this change.
    2. Change from onboard thermostats to low voltage relays, connected to tamperproof wall thermostats. This would have the advantage of rendering the system both tamperproof, and far more accurate in maintain desired temperature. An electrician could easily facilitate this change.
    3. Change system to LPC’s. Between integral tamper-proofing; onboard proportioning for better temperature control & energy savings; these would solve a lot of the problems this gentleman is experiencing.

    Hope this helps
