Question 1

How to choose the power of the wall-mounted boiler to match my home layout?

Accepted Answer

For ordinary residential buildings of 80-150 square meters, choose 24KW, which can meet the heating and hot water needs of one kitchen and two bathrooms; Choose 28KW or above models for 150m2 or larger floor-to-ceiling units or villas; For homes in the south without insulation or those with multiple bathrooms, it is recommended to increase the power by 20% to 30% to avoid insufficient hot water or heating.

Question 2

Does the online purchase of a wall-mounted boiler include installation services? How much is the charge for auxiliary materials?

Accepted Answer

Most online shopping models of brands include free basic installation, but do not include special fees such as high-altitude work and wall drilling. Auxiliary materials such as pipes, corrugated pipes, and filters need to be purchased separately. The total cost of auxiliary materials and special installation fees is usually around 1,000 yuan, and you can consult customer service to confirm the details of the package.

The machine will automatically switch between heating and hot water mode according to the opening of the hot water faucet, and the heating will be temporarily suspended when taking a bath, and the heating will resume after the hot water is turned off.

Question 4

Is there a big difference between first-class energy efficiency and ordinary wall-mounted boilers? Is it worth spending more money to buy it?

Accepted Answer

The main difference lies in energy efficiency. Most of the first-class energy efficiency is condensing wall-mounted boilers, and the thermal efficiency can reach more than 107%. It can save 15% to 20% of the gas fee compared with ordinary non-condensing boilers. It is very cost-effective to use it for a long time, especially for large houses or families who use hot water for a long time, and the saved gas fee can quickly cover the difference.

Question 5

The old house doesn't have pre-installed heating pipes, can I install this wall-mounted boiler?

For old houses or houses that have already been renovated, you can choose the open-air radiator system, which does not need to damage the walls and decoration during construction, has a short construction period, and has a good appearance after installation.

Question 7

Can the wall-mounted boiler still heat normally after the water supply is cut off?

Accepted Answer

It can heat normally. The heating system is a closed water circulation system, which does not need to be filled with water in real time, and water stop does not affect its operation; However, hot water depends on the supply of tap water, and it cannot be used after the water supply is cut off.

Accepted Answer

When you go out for short time, you can turn on the machine's anti-freezing mode, keep the power and gas on, and the equipment will automatically maintain a low temperature to prevent freezing. If you are away from home for long time, it is recommended to turn off the water, electricity and gas, drain the water in the machine and pipes, and avoid water freezing and damaging the parts.

Question 9

Does the wall-mounted boiler consume a lot of electricity? Will it consume a lot of electricity during operation?

Accepted Answer

It doesn't consume much power. The main power-consuming components are the fan and the water pump, with a rated power of only 100-200W, and they do not run continuously; they are synchronized with the start-up and shutdown of the heating system, and the monthly power consumption is roughly the same as that of a household refrigerator.
