LEAFHouse- Tankless hot Water Back-up

At the LEAFHouse, they use tankless hot water for back-up. To get started we'll be only using tankless and install solar hot water later. FL is certainly ideal for solar water heating in general.

At the LEAFHouse, "[Their] system features a tankless water heater, the Stiebel Eltron Tempra 20. Maryland’s average yearly “insolation,” or amount of sunlight available to make hot water, is 3.98, which is a little low as compared to a sunny place like California at 5.4. This means that, especially during the winter months, when insolation is low, the backup water heater will be doing its job." This tankless cost $500.
