How Do You Compare Gas Tankless Water Heaters?
Gas tankless water heaters, also referred to as instantaneous or demand water heaters, provide virtually instant, on-demand heated water. In the long run a gas tankless water heater can save you space, energy and money. Purchasing a tankless water heater is a considerable financial investment. Before diving headfirst into the purchase of a gas tankless water heater, there are several factors to consider when comparing models. Compare the flow rate capabilities of each model. To calculate the amount of flow rate your tankless water heater will need to have, add up the maximum number of hot water devices you expect to have open at any one time in your household. Use the figures below to add up their individual flow rates and calculate your total peak time household flow rate. Flow Rates Per Minute: Faucets: 0.75 – 2.5 gallons Low-flow showerheads: 1.2 – 2 gallons Older, standard showerheads: 2.5 – 3.5 gallons Clothes washers and dishwashers: 1 – 2 gallons Read inlet temperature ratings.
