The internet is full of information, but there’s nothing like a good old picture.
Take a look at the following pictures and see what type of water heater or heating system you need help with.  To easily figure out if you have an oil fired water heater, COMPARE YOUR OIL FIRED WATER HEATER WITH ONE PICTURED BELOW.  These are all the most popular types of oil fired water heaters that will be found in Connecticut.

“Standard”  Oil Fired Water Heaters:  Like these pictured below.

Oil Fired Water Heaters

are easy to identify, they have to distinct things about them.

  1. An Oil Burner will be sticking out the front lower portion of the tank
  2. They all have silver colored exhaust venting connecting them to the chimney

Storage Tanks

are commonly found connected to oil fired boilers:

Storage Tank water heaters are connected to a small chamber of the front or side of an oil fired boiler, called, a Tankless Coil.   Many residential oil fired boilers have these “Tankless Coils” which produces the domestic hot water safely in a separate chamber within the boiler, which does not cross connect with the boiler water.

Storage tanks DO NOT have any exhaust venting, like this ->

Indirect water heaters

have a separate dedicated zone off the boiler for it’s source of hot water.   They use the hot water from the boiler and a pump pushes that scolding hot water to an inner coil (pic right) which is a heat exchanger, passing the boilers hot water safely to the protected tank of surrounding domestic water for home and personal use.   This is a side cut away picture of what all indirect water heaters look like on the inside.
Below are pictures of 2 Indirect water heaters:
