Energy saving is hot water
Do you turn on the lights at home all night? of course not. Do you park your car engine in the workplace or at home to keep it warm? absurd! So why is there only a water heater to keep warm all day and night when no one is using it?
Water heaters with water tanks continuously heat and reheat water throughout the day and night. Of course, adding insulation blankets helps keep the water in the tank longer, but the hot water in the pipes keeps cooling, let alone all the natural gas and propane that waste the entire day and night to warm the flue. Already.
How do you save money and stop wasting energy?
Replace domestic water heaters with one or more tankless heaters. Tankless heaters heat water only when needed, and not when not needed.
There are several Tankless brands available. The most popular (in alphabetical order) are Bosch, Paloma, Rheem, Rinnai, Ruud, and Takagi.
Resizing a tankless heater
The plumber recommends choosing the size of the water heater based on the amount of water used and how long it takes to reheat a full tank of water after use. I bet you don't have time to wait 30 minutes or longer after each family member has taken a shower? Greater demand requires water heaters with larger water tanks. For example, a typical 40 gallon water tank natural gas heater operating at 40,000 BTU may take up to 40 minutes to reheat a full water tank. A typical electric heater may take an hour to reheat a 40-gallon water tank.
Tankless water heaters have different sizes. They provide hot water and hot water as soon as you need it. A medium system with a flow rate of 6 gallons per minute (6 GPM) can continuously output 360 gallons per hour. Use the table below to estimate the approximate size of a tankless heater, or to be unsure of your plumber. Obviously, a small device running at 2.2 gpm is suitable for a single bathroom or kitchen, but the capacity is not enough to meet the needs of the entire house. The medium tankless water heater has an output of 6-6.6 gpm, while the large domestic tankless water heater has an output of 8 gpm. Up to 4 residential tankless water heaters can be strung together in a centralized system to serve large houses or distributed throughout the house to provide 'instant' hot water supply where needed.
