Solar Schematics

A Solar Heating system can be connected to the heating system of a house in a number of different ways. Here are a few examples.

Domestic Hot water: Twin coil tank system

This is the most typical type of solar heating system and it heats the Domestic Hot Water only.

A twin coil water heating tank is used as a solar store with the solar circuit connected to the lower coil. The tank used should be tall and narrow to ensure good stratification of the heated water. An oil or gas boiler or pellet boiler is usually connected to the upper coil.

In this type of system the solar system will be able to provide a large percentage of the domestic hot water needs of the household.

Domestic Hot water: Single coil tank with heat exchanger

This type of system is used less often but can be a good solution where an existing tank of suitable volume is already installed but no spare coil is available.

The heat from the solar panels is fed to a plate heat exchanger which in turn is used to heat the domestic hot water. It may be a good choice where it can be retro-fitted to an existing water heating tank.

In this type of system the solar system will be able to provide a large percentage of the domestic hot water needs of the household.

Domestic Hot water: Buffer tank to pre-heat the Domestic Hot Water

This type of system is rarely used.

The solar system is connected to a separate buffer tank which in turn feeds the existing water heater.

In this type of system the solar system will be able to provide a large percentage of the domestic hot water needs of the household.

Central Heating: Combination tank system

This type of system is used a lot in new build houses where multiple heat sources need to be connected together.

The solar system is connected to a combination tank. The combination tank allows the output of the solar system to make a contribution to central heating as well as providing hot water heating.
