How does an indirect heating system work?

An indirect water heater uses the main furnace or boiler to heat a fluid that’s circulated through a heat exchanger in the storage tank. The energy stored by the water tank allows the furnace to turn off and on less often, which saves energy.

What is the difference between direct heating and indirect heating?

Direct and indirect heat are both terms that refer to grilling or open-fire cooking. Direct heat means to cook the food directly over the heat source (whether charcoal, gas, or wood), while indirect cooking refers to cooking adjacent to the heat source.

Why does the top of a Fortic tank always heat?

The water in the top part of a fortic (combination cylinder) will always heat as there is nothing to insulate it from the water below. Fit a new overflow, preferably in 32mm in the right position and blank the old one. Make sure it is properly sealed.

What do you need in a Fortic indirect cylinder?

The cylinder comprises a cold water cistern and a hot water tank in a single unit and can be specified with Supercal or Ultracal coils on request for faster reheat. Units manufactured to Maxistore specification are also available.

Do you need a cold feed for a Fortic tank?

Fortics are fine. Have a combi heat one and have the shower off the combi for high pressure. If if the cold feed is blocked. You can cut a hole in the upper tank and get to the bottom of the hot section, then insert a pipe. A new cold feed. Sometime you may be able to use the drain off point – depends on cylinder. Now then Walter!

Are there indirect patterns for hot water cylinders?

Indirect cylinders can be made to an Economy 7 pattern. Hot water cylinder incorporating built-in cold water compartment. Heated electrically. (Historically known as ‘Fortic Tanks’. When sizing a cylinder remember the stated dimensions do not include the thickness of insulation.

What makes a Fortic cylinder hot water tank?

A Fortic cylinder or Fortic hot water tank; alternatively, a combination cylinder, is a vessel designed for heating and storing hot water in the home. It is typically made out of copper and covered in a layer of foam insulation. Unlike a standard vented hot water cylinder, a Fortic cylinder has its own integrated cold water storage cistern.

How does a Fortic boiler heat exchanger work?

The heat exchanger is normally in the form of a coil of copper pipe, which carries hot water from the boiler. Water enters the top of the coil via the “flow”, and exits at the bottom by the “return”. These are typically 22 mm fittings. It is possible to buy primatic Fortic cylinders.

Can a Fortic cylinder be used for a combi boiler?

A direct Fortic cylinder is an effective solution for providing hot water in a property with no loft or gas supply, i.e., there is no space for cold water cistern and no gas for a combi boiler. However, Fortic cylinders do have their drawbacks.
