The immediate possibility - is a leak in the system somewhere. If the system is leak-proof, the pressure should remain constant - no matter what time of day it is. The only time there should be a pressure difference - is when the boiler is running.
Your best solution - would be to get your system checked by a qualified service technician.
In the combo boiler for the central heating? You need a small piece of hose (or it might have a permanent connection) to fix to the mains from the boiler. Then turn the taps near the boiler for the mains and the boiler. You want the pressure to be about 1.3 bar
A back boiler is a heating unit installed behind a fireplace that heats water for central heating or domestic hot water, often using the heat from a fire or gas. It is commonly used in older homes as a space-saving and efficient heating solution.

The cost to install a central heating boiler varies greatly depending on how big an area you have to heat and how cold it gets in the winters where you live. For a 2000 sqare foot home, it appears that it would cost between 6 and 8,000 dollars to purchase a boiler and have it installed.
This question can't be answered. It is unclear what you mean by back pressure. Maximum Allowable Working Pressure in a boiler is calculated using the rules for construction of high pressure boilers and construction of heating boilers in the ASME Code sections 1 and 8.

Central Heating Power Flushing can be necessary if there is a large build of of substances within the central heating pipes, the boiler, or the radiators. These substances can cause build of of pressure within the boiler to dangerously high levels, as well as preventing hot water from flowing properly through pipes.
No, it is not okay to put your oil central heating boiler outside. It should be in an enclosed area.
The boiler service and central heating system, including the radiators, are covered under the Boiler & Central Heating System Cover. The annual boiler service is also included in this. In comparison, the home cover policy has all the elements listed above but also covers problems not related to boiler heating service.
The boiler pressure should be around 1 to 1.5 bar when the heating is turned off.
Because it has air in it.

A back boiler is a heating unit installed behind a fireplace that heats water for central heating or domestic hot water, often using the heat from a fire or gas. It is commonly used in older homes as a space-saving and efficient heating solution.
Central heating service is an annual service that should be carried out by a boiler engineer. During this service they must check to make sure a boiler is running safe and cost-effectively.
Yes, a conventional boiler typically operates as a low-pressure boiler. Low-pressure boilers are designed to operate at pressures below 15 psi, which is common for residential heating systems. These boilers use water or steam to transfer heat, providing efficient heating for homes and buildings.
Boiler pressure does not directly affect water temperature. Water temperature is primarily controlled by the thermostat setting on the boiler. However, excessive boiler pressure can lead to other issues such as leaks and inefficiency in heating the water.
Some reliable brands known for making solid central heating boilers include Worcester Bosch, Viessmann, Baxi, and Vaillant. It's important to choose a reputable brand that offers quality and durability.
