Air energy heat pump

Advantages: Scope of application Wide, energy-saving effect, environmental protection, safety, high comfort

Disadvantages: The purchase cost is relatively high, the installation and maintenance are more troublesome

Price : High

Principle: The unit uses a small amount of electricity to drive the compressor to work, absorb the low-temperature heat in the air, and pass it through the condenser or evaporator. hot Exchange, heat the cold water

Central heating problem Pipeline problem

Pipe leakage: For a long time, sand holes will cause water leakage. If it is not serious, you can use sealant and raw material tape to wrap it tightly. Change PPP pipe

Pipe dripping: The valve is not fully opened or the opening is too small, or the water flow is not washed by debris, adjust it manually, and turn the return water fully open to adjust Water supply

There is a lot of scale: If the radiator is used for a long time, scale will inevitably appear inside the pipeline. Protect the entire system

Pipe air: Check that the pipe valve is open or fully open. The exhaust valve of the user’s home on the top floor is opened to remove the air in the pipes

radiator problem

Half hot and half not hot: There is too much gas in the radiator, open the vent The valve releases the gas; the pipeline is blocked, please professional maintenance personnel to check and remove the pollutants.

Hot up and cool down: The valve of the water separator is not opened; the temperature control valve is not Turn it on and turn it counterclockwise to the end; it may also be poisoned by stolen goods, the inlet water pipe is reversed, etc.

The deflation needle is broken: Immediately use a thick towel, rag and other items Block or entangle it to reduce water flow

Low room temperature: If the number of pieces is small, you can add 1-2 pieces. If the floor is high or low, you need more , improve the sealing degree of the room

Overheating:Adjust the temperature control valve, lower the temperature slightly, the temperature will slowly drop after half a day, use a large humidifier, appropriate Open windows for ventilation

Other problems

Burst and leak of radiator: When the radiator bursts and leaks, immediately close the door valve, and then ask a professional to repair it

Occupy space and want to move: It is recommended not to move the radiator casually. If you really want to move, you can find a professional company to redesign the pipes.

Water leakage in heating facilities:The water flow is not If it is too large, you can gently wrap the pipe with a towel or a rag, and ask the professionals of the heating company to repair it.

The insulation material of the heating pipeline falls off: Once you find it, you should immediately report to the heating company. The heating company should send someone to replace or repair it in time.

Household heating problem food

Advantages Improved comfort, high space utilization, controllable cost, controllable scope, easy installation

How to arrange pipes indoors, according to the same plane Each household in the location is equipped with a common water supply and return riser; if it is set outdoors, each population is equipped with a common water supply and return riser

How to do concealment is mainly indoor concealed installation, and there are many ways of concealment, such as Install decorative partitions on the outside, buried pipes in the wall, etc., but choose the pipes, pipe routing and construction methods

Frozen cracked parts of the hot water pipes are sawn off with tools, and then connected Install a new pipe

Contact the relevant departments of the gas company and the heating company in time for natural gas leakage, and cut off some natural gas heating equipment in time

Water heating problems

First use or long-term unused When the floor heating is used for the first time, the heating will be relatively slow, and the heat transfer of the pipes will be relatively long.

The water floor heating system is not turned on. Check whether it is not fully turned on, and whether the floor heating system is fully turned on

If the water temperature is not up to standard, check whether there is a problem with the heat source equipment unit used, or whether it can meet the hot water temperature demand

The pipeline pressure is not enough During the construction of floor heating, the pressure test of the pipeline will be carried out to observe whether the floor heating pipe is cracked On

If the pipes are not cleaned for a long time, the floor heating pipe will produce dirt, which will make the temperature in the floor heating pipe not rise, so the floor heating pipe needs to be cleaned

The filter is blocked Be careful that the filter is blocked by scale , during the inspection process, the entire system can be inspected again

The floor heating was not installed according to the construction specifications when the floor heating coil was constructed, resulting in the floor heating not hot and only re-construction

Water seepage If there is water leakage, close the heating valve in time, close the valve of the water separator to control the water leakage, and seek professional maintenance personnel for maintenance.

Common problems of wall-hung boilers are insufficient pressure

phenomenon: The water pump does not turn, the controller Alarm, the fault code is insufficient pressure

Cause: Lack of water in the pipe, switch failure, a lot of air in the system

Solution: Carry out water replenishment, check with a multimeter, if the pressure switch is not turned on, replace the switch, and exhaust the pipeline system

Water shortage in the pipeline

Symptoms: The water pump does not run, the fan does not run, The fault code is water shortage in the pipeline

Cause: The power cord of the water pump falls off, and it does not need to be locked for a long time

Solution: Multimeter detection Whether the output power is normal, whether the contact is good, replace the wire, replace the water pump

Fan air pressure failure

Symptoms: The fan does not run or runs slowly, Display fan air pressure fault code
