Over time, parts of the heating system structures wear out and repair is required. The owners of private houses have to carry out heating repairs on their own. Therefore, it is important for everyone to know what malfunctions occur in the operation, and how the situation can be corrected. And it is important for owners of private houses in California to know who is engaged in heating repair in Sacramento.
Main types of construction
The heating system is by its nature closed, and in the simplest implementation it is a ring of pipes. The principle of operation is the circulation of hot liquid, which is heated in the boiler, and transferred to the equipment. Further, the transfer of thermal energy occurs, after which the liquid is sent to the boiler for reheating. Such circulation has a periodicity.
There are two main adaptive options for the heating system:
· gravity
· pump
A distinction is also made between open and closed circuits. A difference is an expansion tank. It maintains the pressure level and provides compensation for the expansion of the coolant.
Gravity system
The continuous movement of hot liquid is due to the use of the necessary slope of the direct and return pipelines, as well as the presence of pipes of different diameters. The choice of pipe diameter is carried out according to the principle: supply from the boiler — a smaller size, towards the boiler — a larger one.
Advantages:
· even distribution of heat
· sustainability of action
· autonomy
Disadvantages:
· installation complexity
· pipeline length
· system inertia
· high water temperature (restriction for the use of materials)
Pumping schemes
The circulation pump, connected to the mains, ensures the uninterrupted operation of the heating system in the house. This scheme is good because it gives unlimited possibilities for using materials for pipes, as well as the versatility of installing heating equipment.
1. Single pipe system
This version is the easiest to install, does not require increased labor costs, and has a relatively affordable price. Equipment is connected in series, the return flow for the coolant is not provided by the system. The system is widely used in private houses.
Two-pipe system
It is used in all types of houses. Its main principle is the supply of heated liquid through one pipe, the outlet through the other. Heating equipment is installed in parallel, unlike a single-pipe system.
Warm floor
Horizontal radiation is used, adjustable depending on the level of height. In warm climates, such a scheme can act as the only source of heating. If the climate is cold, then it is necessary to combine the scheme with the installation of a full-fledged heating system.
“Spider”
This is a heating system for a private house with a top spill that does not need a circulation pump. The main value is complete autonomy of gas or electricity. The distribution of the heat carrier is ensured by different levels of temperature at the inlet and outlet of the heating equipment.
Without temperature control
The system operates on the principle of a single-pipe, but with a looped circuit. It is used most often in one-story houses, and is a fairly effective and economical option.
Beam system
The liquid is evenly distributed by means of a collector. It is possible to regulate the degree of heating by changing the temperature and the rate of distribution of water. This option is an improved version of the two-pipe scheme using a collector in the underfloor heating system.
If you cannot determine on your own which heating system is installed in the house, contact a repair specialist — for example, Alfa Mechanics.
Types of breakdowns according to the complexity of repair
Breakdowns of the home heating system are of two types — fixable on their own and removable only by specialists. The former includes external mechanical failures, the latter – malfunctions in boiler equipment.
Batteries do not heat up
Batteries may not heat up due to the accumulation of air in them. The presence of gas in the system can be checked by opening the controls – the outflow of air will be accompanied by a whistle.
Cold radiators
If system blockage is suspected, shut off all radiators in the system except the suspect one. If it starts to warm up, then the system is clean. Then it is necessary to carry out hydraulic equalization by closing other branches of the system.
Pressure drops
When the system has worked for more than a month, then it is worth rechecking the dimensions of the expansion tank — if they are small, then a pressure surge occurs, the safety valve is activated and the pressure decreases.
Imbalance
In the case of a hot return, the reason is the installation of a pump without a non-return valve or a floor heating pump. Initially, the pump works at full capacity when it starts and the circulation in the house heating system can be ‘demolished’ as the result.
No circulation
To begin with, the accumulation of air in the batteries might be the reason for that. In this case, you need to release it. Then the taps have to be checked, which can be closed because of inattention. Finally, you need to take a look at the filters in front of the boiler and in other areas.
Make sure they are clean and work properly. If the condition of the system deviates from the set value by 1-2 degrees, the checking process can be considered successful. Otherwise, you need to call a professional to help you out.
Prevention is easier than cure
To reduce the frequency of breakdowns before the start of each season, it is necessary to regulate the system. First, the valves at the input of the heating system are opened. Then water is supplied to the pipelines from the heating network.
When the water is inside the pipes, experts (possibly from Alpha Mechanics) examine the mains for heating of the lower sections of the risers. The main objective of the measures is to create the same temperature conditions for all risers.
Heating must be provided for equipment on each floor of the house. The desired temperature is controlled in the central section of the device, which is located farthest from the riser.
When starting a system after a long downtime, it may take a week to balance it.
