Indirect water heaters are a more efficient choice for most homes, even though they require a storage tank. ... An indirect water heater, if used with a high-efficiency boiler and well-insulated tank, can be the least expensive means of providing hot water, particularly if the heat source boiler is set to "cold start."
In all cases, how big of an indirect water heater do I need? A 30 gallon indirect heater would be enough hot water for 12-14 people because a boiler consumes so many BTUs and heats to such high temperatures, that it can easily keep up with demand as it occurs. Boiler and indirect heater are truly 'unlimited' hot water.
Never mind, is a 40 gallon indirect water heater enough?
What Size Should my Indirect-Fired Water Heater Be? If you are replacing a conventional 40 or 50-gallon water heater and it was sufficient for your needs, simply match it up with a similar capacity indirect-fired water heater.
How much does it cost to install an indirect hot water heater?
Indirect Water Heaters This water heater model is energy efficient, relying on heat created by a boiler or furnace. Although the monthly price of an indirect water heater is low, the initial purchase and water heater installation cost is more expensive than traditional heaters and is priced around $1,500.

A direct-fired water heater can be heated by propane, oil, or natural gas and has its own burner. ... They are more energy-efficient than an indirect water heater because it heats the water itself. Indirect water heaters rely on the furnace or boiler to supply the heat needed for the water.
For a tank-style heater, household size is a simple indicator of hot water needs. You can estimate the necessary tank capacity (in gallons) based on the number of people in the house: 1 or 2 people—23 to 36 gallons. 2 to 4 people—36 to 46 gallons.
Indirect systems In this case the hot water is heated and then travels through a copper coil in the hot water tank. The heat is then transferred from the from the external heat source to the water inside the hot water tank. Indirect cylinders tend to be fitted with a direct backup (such as a immersion heater).
