The Flash
water heater, model T-K1, is an on-demand, tankless gas water heater.
This space saving, highly energy efficient water heater can deliver
over 200 gallons of hot water per hour and since there is no tank
to run out, you get an ENDLESS supply of hot water.
The Flash utilizes the latest in technological controls for efficient
water heating. These include computer modulated gas valves, electronic
temperature sensor, electronic water flow sensor, electronic ignition
(no pilot burner), computerized safety devices and even pipe heaters
to protect the unit when the temperature is near freezing. Because
of these advance controls the Flash is compact, about the size of
a small Pullman suitcase, yet 5 times more powerful than the average
storage tank water heater. The Flash has a self modulating input rating
of 37,000 to 165,000 Btu.
The Flash with its durable design and rust resistant powdered coating
is made to be installed outdoors also.

With
a storage tank, you store 40-75 gallons of hot 140*F water 24 hours
a day, 7 days a week though you only use hot water a couple times
a day. The tank type heaters constantly lose heat through the flue
and tank walls trying to maintain 140*F. The heater cycles on and
off to maintain this temperature. This causes cracking of the exterior
walls and sediment build up which will eventually cause your storage
tank to leak. The storage tank is designed to wear out and be
replaced in time. Also, the storage tank water heaters only
have a limited amount of hot water and after that is gone you have
to wait for the tank to get heated again.
The Flash heats the water only when there is a demand for
hot water. Opening a hot water faucet, ignites the powerful burners
and the computer monitors the water temperature and adjusts the
burners according to the need. High demand, high heat. Low demand,
low heat. With no tank to run out you get an endless supply of hot
water. No tank to heat means no standby heat loss. The Flash
provides a continuous flow of hot water and will never run out,
but the flow rate is limited to the temperature that you set. With
a self modulating input rating of 37,000 to 165,000 Btu's this unit
can handle a small application like a bathroom faucet and can take
care of large demand application like a washing machine or dishwasher.
This heater is designed to give you the maximum amount of hot water.
With the 140*F temperature setting, you will need to mix it with
cold water to get the water temperature you desire.
For residential customer who pays $50.00/ month on natural gas for
Domestic water heating (DHW) ONLY, we project average savings of
30% based on same usage pattern. (Best way to find DHW energy cost,
is to look at Natural gas bill during summer without heating.)
With usage pattern the same, savings will be average 30%. Single
person 55%, two people using tank 40%, three people 35%, four people
30%, five people 25%.
Based on: $50.00/month DHW gas bill, average 30% savings, you would
save $15.00 month or $180.00 per year. If tankless Takagi costs
$1500.00 installed, alternative tank type water heater costs $600.00
installed, the differential of tankless is $900.00. Payback is 5
years. Return On Investment 20%.
