1, I have 18 shower room, with the floor, intended to use three 16L gas water heater, separate equipment, one by one 6 shower. This will not be cold or hot, not even hot water?
2, if the heating speed hot water heater, the price higher, there is no other way?
16 liters of gas water heater up to the same time with three showers, if you reload three solar water heaters should be enough, both economical and affordable.
Shower water to be 5 to 8 liters per minute. 16L take 6 shower too small.
At the same time, the water temperature of the gas water heater (including other hot water heaters) is usually related to the size of the water, and the multiple showers will certainly affect the water temperature.
Multiple showers are hot water, preferably hot water tanks.
For gas water heater, I am very familiar. But still do not have enough say on your question.
Where the problem is, the frequency of your use of water heaters. 16 liters of water heater at the same time for 6 people, the distribution of each close to 3 liters, the water is too small, simply do not use, with 2 to 4 is the largest span.
18 shower bits, the overall use of 6 to 8 sets of water heaters more appropriate. Will all water heater into a network, according to the number of baths to decide to open several machines. The benefits of networking are the ability to reduce the effects of water temperature instability during the halfway boot.
Electricity that is hot can not, water small, high failure rate. Home are free, let alone business.
Of course, the above calculation is the total amount of water used in 18 showers at the same time, if you have a gap, you can calculate the total water for 10-12 shower, then use 1000L of the storage tank plus five 16 liters Water heater on it.
?
Or you want the most simple way, then you choose to install nine water heaters, each with two shower heads, so the effect of bath better, or else there will be a lot of people call. Of course, you can also choose to install 6 water heater, each connected to three shower heads, but the effect will be far from satisfactory.
In response to this situation, in fact, the market has long been a mature program, but to increase the other accessories, which is mainly to increase a hot water tank, a tank temperature sensor, plus a constant temperature circulating pump. The hot water used by the user is from the hot water stored in the storage tank.
?
According to the national standard, the standard water consumption of a shower is at 150L, and you now have 18 shower, so the total maximum water consumption is at 2700L.
Approximate storage tank volume = total water consumption × (water temperature - tap water temperature) ÷ (water temperature - tap water temperature) × 70% × 1.3 = 1579.5 approximately equal to 1600L
Note: The calculation is usually used, the storage temperature of 60 ℃, tap water temperature of 4 ℃, the actual water temperature of 40 ℃.
70% of the water tank for the effective water consumption, 1.3 for the tank volume factor.
?
So you need to choose a 1600 liters above the storage tank, and then according to the equivalent heating power tank, choose how many gas water heater. While the 1600 storage tank, then about 250KW, it is equivalent to the need for seven 16 liters of gas water heater.
