| 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%.
