The Takagi T-K1 Water Heater Will Save You Money...

The Flash water heater, model T-K1 is very small, (more or less the size of a small Pullman suitcase). However big things or should I say powerful heaters come in small packages, as the T-K1 is actually 5 times more powerful than the average storage tank water heater.

The Flash boasts of a self modulating input rating of 37,000 to 165,000 Btu. Because of its durable design and high resistance to rust, (due to powdered coating) Model TK1 can actually be installed outdoors.

Using a storage tank, you are able to store between 40 to 75 gallons of hot 140*F water everyday, athough you only use hot water a few times a day. The tank type heaters continuously lose heat through the flue and tank walls trying to maintain 140*F. The heater cycles on and off to keep this temperature. The exterior walls will eventually crack and sediments build up and cause the storage tank to leak.

The Flash T-K1 heats the water only when there is a need for hot water

The storage tank is actually manufacturedto wear out and be replaced over time. The storage tank water heaters only have a limited amount of hot water and after this is finished you will need to wait for the tank to get heated again.

The Flash T-K1 heats the water only when there is a need for hot water - thus the name "on-demand water heaters". When you open a hot water faucet, the powerful burners come alive and the computer monitors the water temperature and adjusts the burners according to thespecific need. High demand results in very high heat while low demand results in the opposite.

There is no tank on the Flash T-K1 model - and thus there is nothing to run out off, especially when you really need to take a warm bath in winter. The flash water heater has 0 standby heat loss and 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 the Flash T-K1 unit can handle a small application like a bathroom faucet and can successfully heat water for the washing machine or dishwasher. This heater is constructed 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 need.
