6 FAQs about [Hot water storage calculation]

How do you calculate a storage water heater tank size?

The calculation method differs depending on the type of water heater you intend to use. The best way to estimate the size of a storage water heater tank is to work out your peak hot water demand. This is when you and your family use the most amount of hot water.

How do you calculate heating capacity in a domestic hot water system?

Input heating capacity of a domestic hot-water system: hin = q ρ dt cp / μ (2) where hin = heating capacity, input (Btu/h) μ = efficiency Recovery rate for an electrical heater in a domestic hot water system: RR = hin μ / dtρ = P (3413 Btu/kW) / dtρ                              (3) where RR = recovery rate (gal/h)

How do you calculate recovery rate in a hot water system?

Recovery rate for an electrical heater in a domestic hot water system: RR = hin μ / dtρ = P (3413 Btu/kW) / dtρ                              (3) where RR = recovery rate (gal/h) P = electrical power supplied by heater (kW) Temperature rise in an electrical heater in a domestic hot-water system: dt = hinμ / qρ

How big is a tank storage water heater?

The size of a tank storage water heater is measured differently from a tankless water heater. Storage tank heaters are rated by the amount of hot water they store in gallons. Typical capacities vary from small 6-gallon point-of-use st orage heaters up to 100-gallon home water storage heaters.

How do I calculate the size of a water heater?

Another method for estimating the size of a water heater is to use an online water heater calculator such as A. O. Smith's XPERT Residential Water Heater Selector. The advantage of this type of calculator is that it allows for the length of your showers, the number of back-to-back showers and the size of your bathtub.

How do you calculate a domestic hot water sizing equation?

Domestic Hot-Water sizing equations - heating capacity, recovery rate and power supply. Domestic hot-water systems supplies taps in houses or buildings with hot water. Output heating capacity of a domestic hot-water system: hout = q ρ dt cp(1) where hout = heating capacity, output (Btu/h) q = flow rate (gph) ρ = 8.34 - density of water (lbs/gal)
