How about the Riyalu condensing furnace?

"HVAC Diary" Wuhan Hanyang users use Liyalu brand family series condensation wall-mounted gas stoves test report.

Two years ago, the heating and air conditioning amateur said in a column

How to change the title of this article to the following one?

A house with a heating area of 90 square meters. Including domestic gas. How to achieve 5 cubic meters of gas per day with wall-hung boiler radiator heating?

It is estimated that more people will watch it. After all, I am also a title party.

Keywords: 90-flat heating room # During Wuhan epidemic # Indoor constant temperature 22℃# 5 cubic meters of gas per day

Today we came to a family near Chucai Middle School in Hanyang District, Wuhan.

Let's take a look at the approximate energy consumption of Liyalu wall-hung boiler in 20 19 and 2020. The family series boiler of Liya Road is used here. We often say that Beretta, Vokla and Hillbo are its brands.

Using these four brands of wall-hung boilers, you will find that the accessories inside are exactly the same. It's just that the shell is different

General configuration list of customer's residence

Liyalu series condensing wall-hung boiler

Five-way water separator

Demelard radiator

OT protocol thermostat

Liyalu family series, the minimum running power of heating is 3.6kw.

When buying a wall-hung boiler, in addition to the brand, you should also remember the above two values. It is closely related to your life.

This product has low minimum working power,

The first is to ensure the stability of domestic water in summer. There will be no difference between hot and cold.

Secondly, under the condition of low power, it can really realize efficient operation with minimum load. Avoid frequent startup.

Different from some brands, the minimum power of condensing furnace is almost the same as that of conventional furnace.

Only by boring blowing and pyramid schemes can we save energy.

Let me talk about the configuration size of the room area first.

The certified area is 109 m2, and the actual heating area is about 90 m2.

One has five radiators.

I used my favorite Demera radiator. Fins have good density and high heat dissipation value.

It is worth noting here that

This place is adopted.

OT(opentherm) and radio frequency protocol thermostat

The logical control of this thermostat is as follows.

Control logic diagram 2

Control logic diagram 3

It is worth noting that all the protocols here are completed through wireless fidelity. The boiler can be connected wirelessly.

Will someone say I screwed up again and talk nonsense?

In fact, German brands also use these thermostats as standard equipment in Europe.

So why is such a good thing not promoted in China?

Actually, it's in Wuhan Guanghua HVAC. Thermostats that were the first to popularize the OT protocol. But in the whole wall-hung boiler HVAC market, bad money drives out good money. Users only care about the brand effect and ignore the essence of the product itself. Considering the cost, it didn't persist in the end.

As all customers know,

This is a German brand, and this is an Italian brand.

hear nothing of

Temperature controller of OT protocol.

Minimum power of domestic water for wall-hung boiler

Minimum output power of wall-hung boiler heating

These really useful things can help your energy-saving products.

Let's look at the mobile phone again.

Beretta thermostat

Finally, let me blow on the energy consumption.

During the epidemic, there were four people in the family. They are all at home. The energy consumption of natural gas includes domestic water and cooking.

The home is heated by radiators, with a constant temperature of about 22 degrees Celsius and 5 cubic meters of air every day.

The blow is over.

Why does this thermostat look exactly like Bosch's OR80 RF version? In addition to the different arrangement of display content, there are many WiFi connections and APP functions. Is Bosch OR80 castrated?

By the way, after reading your article, do you recommend installing a central thermostat? It's just an iron box, which connects the water pump, wall-hung boiler and thermostat through wire control. What is your background?

The central control box is generally used for floor heating, which is used to connect the wall-hung boiler with the temperature controllers in each room, that is, when the temperature control panels in all rooms reach the temperature, the boiler will automatically stop. The OT protocol thermostat mentioned by the landlord in this paper is the main thermostat connected to the wall-hung boiler, which is generally used in radiator system or small area floor heating system. It is divided into wired or wireless, and wireless is generally recommended. It can be moved and placed, and the price is not expensive. A better set of 300-401 sets is used to adjust the indoor temperature until the boiler stops. We are all standard now [laughs].

I would like to ask, generally, whether to take the dark line or the open line, how much is the difference between the open line and the dark battle, and the indoor area of the suite is 95.

Again, the temperature in Wuhan last winter was not particularly cold. The user's home insulation is doing well. So the energy consumption is not high.

If there is a wall-hung boiler heating system, the outlet water temperature can be automatically adjusted according to the change of weather temperature outside, and it is not frequently started and stopped. Keep burning if necessary, and stop if not. That's good. After all, there are three bedrooms and four bedrooms.

This is a large apartment, and a small apartment really doesn't need too much score control. The minimum operating power and frequent start-up value of wall-hung boiler are also very important.
